- An animal’s digestive system contains all of the organs necessary to take food and change it into a form the animal’s body can use.

- A plant’s root system includes a primary root, secondary roots, and root hairs. The root system brings water and nutrients into the plant from its environment.

SURVIVORS ACTIVITY:All plants and animals have to respond to changing conditions in their environment. For example, a dog pants

when it is hot. In this activity, you will research some other ways that plants and animals adapt to survive.

What to do: 1. Research at least 7 other unique ways that plants and animals respond to changes in their environment

Animal/Plant AdaptationSnails Snails become inactive during the hottest, driest parts of the summer

when food and moisture are scarce. This is called torpor.Bears During the winter, a bear becomes inactive to avoid winter food

shortages. Its heartbeat and breather slow. Its body temperature is lower than normal. This is called hibernation

Have your food choices over the past few days been healthy or unhealthy? Why do you think so?

Did any of your choices fit into the food guide on the following page? In what areas do you need to improve?

26

1. Eat a variety of foods.

2. Eat a lot of whole grain cereals, breads, fruits, and vegetables

3. Choose low fat dairy products, lean meats, and foods prepared with little or no fat

4. Participate in regular physical activity

5. Limit the intake of salt, sugar, alcohol and caffeine.

Assessing Nutrients

• __________________________________: is a branch of science that studies foods and how the body uses them

• __________________________________: are substances found in foods that your body needs in order to maintain health

• You get nutrients from the food that you eat

Nutrients that you need27

• __________________________________ – in the form of sugar and starches are the primary source of energy

• _________________________________-build tissue and regulate chemical activity

• _____________________________-are stored in the body for use as an energy when carbohydrates are in short supply

• ___________________________________- organized according to whether they can be absorb in fat or water (E.g. vitamin B and C is water soluble)

- Scurvy, a disease among sailors, was found to be caused by a lack of vitamin `C

• ___________________________________________- help carry out life functions

(E.g. calcium (stored in bones), iron, etc.)

• ______________________________________________ - is essential

• _________________________________- occurs when essential nutrients are missing from a diet

Testing Food Nutrients:

- You can use lots of different things to test if food is nutritious or not- You can use brown paper to see if a food is high in fats.

o Example: Buttered popcorn in a paper bag…..

Use page 200 to fill in the following table about nutrients our body need…

Your job:

Look at the following food labels. It is going to be your job to decide which food is the best choice if you have your health in mind.

Bacon Cheerios

Chewy Granola Bars Microwave Popcorn

30

The Digestive System

• To obtain the nutrients that are in food, your body needs to break up the food into nutrients.

• This process is called digestion and was first researched by William Beaumont

• There are three processes of digestion:

– mechanical and chemical digestion, and absorption

• _________________________________________________- the physical work of your teeth and stomach breaking food into small pieces

• _________________________________________- the enzymes in your mouth, stomach and small intestine help break food down into smaller particles

• _______________________________________ – the small particles move into the bloodstream

Digestion

• ___________________________________ : Teeth reduce the size of food and mix it with saliva (which breaks down starches)

• __________________________________: Breaks down food and mixes it with gastric juices and special enzymes break down protein

• ______________________________________: most chemical digestion and absorption of nutrients (carbohydrates, proteins and fats) occur here

• ______________________________________: absorbs left over water, vitamins and minerals – also stores waste materials and undigested food (feces)

31

The Role of Diet

• Your body needs a good balance of nutrients at regular intervals

• Too many fats (animal fats) can cause:

– High cholesterol in the blood (heart attack)

– Hard work to burn them down

– Feeling ill or even throwing up

– Feeling tired all the time

– Weight gain

Skipping Meals:

• This can cause your blood sugars to lower

• You may become tired, dizzy, and unable to concentrate

32

Chapter 11: Maintaining Homeostatsis

Science 14

36

What you will learn:

- How diet and lifestyle influence internal

balance

- What happens when the body struggles

to maintain internal balance.

- About some technologies used to

maintain internal balance

- DNA

11.1 - What is Homeostasis?The ____________________________ around you is always changing, and as a result, the environment inside your body is always changing as well. Your body responds to temperature changes, stressful situations, increased physical activity and many other situations differently!

Just like a teeter-totter, your body can be balanced or unbalanced!

When your body becomes unbalanced, it will work extra hard to try to return everything to normal (balanced).

When a teeter-totter is in balance, we say it is in ____________________________.

The ability of your body to maintain an internal balance is called ____________________________.

Homeostasis helps maintain the proper conditions of life – all of the systems in the body (digestive, circulatory, respiratory, urinary, nervous, etc.) and all of the life functions work together to maintain homeostasis.

Remember our heart rate labs? What happened when the boys ran up the stairs?

___________________________________________________________________________

After 1 minute, was their heart rate higher or lower than it was just after they ran?

_________________________________________________

This is the body trying to maintain homeostasis! Your heart rate needs to be consistent or else you can experience pain, fatigue, ____________________________ and a consistently elevated heart rate can lead to death.

37

How does our body work to maintain a balance (homeostasis)?

Look on page 217 in your book and describe how each condition is kept in balance by the body.

Condition How it helps keep your body in balance:

Enzyme LevelsEnzyme = a substance that speeds up a process or reaction in the body

Enzymes control the release of energy from food molecules in the mitochondria

Waste Product Levels

Carbon dioxide is poisonous to our bodies – when we exhale, we get rid of carbon dioxide so we don’t get sick

Your kidneys filter your blood and get rid of wastes through urine

Concentration of Substances in the Blood

The circulation of blood to every cell in the body helps to keep the amount of oxygen, carbon dioxide, sugar, vitamins, minerals and wastes at the right levels.

Heart Rate Your heart rate depends on how much oxygen your body needs –when more oxygen is needed (during exercise or stress) your heart beats faster to deliver oxygen quicker

Water Balance Special hormones tell cells to take up or release waterHuman bodies are 60-70% water and need to keep a balance to maintain healthy cell activity.

Blood Sugar Level The level of sugar in your blood is controlled by insulin – insulin tells cells that they need to take sugar from the blood and use it to make energy.

38

11.2 – What affects homeostasis?Remember: the digestive and circulatory systems work together to maintain blood sugar levels, water balance, enzyme levels, and waste product levels.

Many things can interfere with these systems:

If the circulatory system transports too many _____________________, they can build up in arteries and cause serious symptoms including ____________________________

Lack of exercise can create many different problems in different systems Smoking can interfere with your lungs and how effective they are at taking in ____________________________

Take a look at Figure 11.6 on page 222. Examine the different health risks and explain the effects of each.

Factor Effects

Diet high in cholesterol and fats

Obesity

Smoking

Drugs

Lack of exercise

39

11.3 – When Your Body Cannot CopeSome people can eat junk food every day and remain healthy. Others struggle to maintain a balance. What is the difference between these people?

Lifestyle and genetics

Your health depends on your ____________________________ ________________as well as genetics – what traits you’ve inherited from your parents. Some diseases are inherited and some are heavily influenced by your lifestyle. Let’s take a look at some diseases that are common among teenagers:

____________________________

Diabetes can be a genetic disease – you can be born with it or inherit it from your mom or dad. However, an unhealthy

diet and lack of ____________________________ can lead to the development of diabetes at any point in your life.

People who suffer from diabetes have high levels of _____________________ in their blood and urine. This happens

because of a hormone called _________________________: this hormone tells cells in the body to take the sugar that is

circulating in the blood and turn it into energy. There are two types of diabetes:

1. Type I Diabetes (__________________ Diabetes): the pancreas no longer produces enough insulin to control the amount of sugar in the blood

a. This type of diabetes is usually diagnosed in children and is ____________________

2. Type II Diabetes: insulin levels are normal but the insulin is not recognized by cells in the bodya. This type of diabetes develops over time due to ____________________________

Treatments

There is no cure for diabetes – people with this disease must ____________________________ their diet constantly – eating too many foods with high sugar levels can put them at serious risk. Diabetics must take daily insulin shots, eat a ____________________________ diet and exercise regularly.

40

Ulcers

Ulcers are _________________ or breaks in the lining of the esophagus or stomach. Since the stomach contains a strong acid (hydrochloric acid, pH ~ 1) people with ulcers will normally feel a burning or aching in their lower chest region.

Most ulcers seem to be caused by ____________________________. Ulcers can be treated with antibiotics or different medications.

Eating Disorders – Anorexia Nervosa and Bulimia Nervosa:

Eating disorders are a result of ____________________________ and not genetics.

____________________________: people who suffer from this disease do not eat enough because they are afraid of gaining weight. No matter how thin they are, they constantly view themselves as being fat. As a result, they ignore hunger signals, restrict their food intake and compulsively ____________________ to get rid of “excess weight”.

Anorexia nervosa is most common in young people, especially young women. However, it is possible for young men to suffer from this disease as well.

____________________________: people who suffer from this disease eat too much and then force themselves to vomit in order to get rid of the food before it digests. Some people may take laxatives daily to get rid of the food faster. This is why bulimia is known as the “_____________________________________” disease.

These forms of purging can decrease body fluids and nutrients and can also affect heart function. Repeated vomiting damages the esophagus and breaks down tooth enamel due to the large amounts of ________________ in vomit.

41

Some people with eating disorders die of ____________________________; others suffer from malnutrition and an increased number of infections.

Treatment: treatment for eating disorders involves education and ____________________________. Many people who suffer from these diseases will remain hospitalized for an extended period of time in order to get healthy, and often antidepressants are prescribed.

____________________________

A heart attack occurs when blood flow to the _________________________ that supply the heart with blood is restricted. The heart won’t receive enough oxygen and will slow down or stop pumping all together and heart tissues will die.

When the heart stops, it’s called __________________________________. People experiencing cardiac arrest must be treated with CPR or electric shock immediately to start the heart as soon as possible.

Heart attacks can occur as a result of genetics or lifestyle – people can inherit a tendency to develop blocked arteries or suffer from _________________________________________. Diet and exercise can also influence the likelihood of a heart attack.
