Ch. 1 Organ Systems

Choose an organ system. Describe the general functions of that organ system and its parts in a circle map

Organ Systems

Organ Systems: The human organism consists of several organ systems, each of which includes a set of interrelated organs that work together to provide specialized functions. The maintenance of homeostasis depends on the coordination of the organ systems.

3

Integumentary System: Protects underlying tissues, regulates body temperature, and houses sensory receptors

Consists of : skin, hair, nails, sweat glands

4

Sponge

On the top margin of pg 20:What is the main function of the integumentary system?

Protection!!!! • They protect underlying tissue• Regulate body temperature• And house sensory receptors

5

Skeletal System: Provides frameworks and protective shields for softer tissues, serves as attachment for muscles, movement, and tissue within bones produce body cells

Consists of : bones, ligaments, and cartilages

6

Muscular System: Provides forces that move body parts

Consists of : muscles

7

Nervous System: Nerve cells within these organs use electrochemical signals called nerve impulses (action potentials) to communicate with one another and with muscles and glands

Consists of : brain, spinal cord, nerves, and sense organs

8

Endocrine System: Includes all the glands that secrete chemical messengers, called hormones. The effect of hormones is to alter the metabolism of the target cells- occur over a relatively long time period

Consists of : pituitary, thyroid, parathyroid, adrenal glands, pancreas, ovaries, testies, pineal gland, and thymus

9

Cardiovascular System: Or Circulatory System, passes nutrients to and from cells to fight diseases, stabilize body temperature, and maintain homeostasis

Consists of : heart, arteries, veins, capillaries, and blood

• Heart: pumps blood

• Blood: transports gases, nutrients, hormones, and wastes

10

Lymphatic System: Defends the body against infections by removing pathogens (disease causing agents) from tissue fluid

Consists of : lymphatic vessels, lymph fluid, lymph nodes, thymus, and spleen

11

Homework

On the top half of pg. 20:

On the top of pg 22:

What are the 5 parts of the cardiovascular system?What are their functions?

13

Cardiovascular System:

Consists of : heart, arteries, veins, capillaries, and blood

• Heart: pumps blood

• Blood: transports gases, nutrients, hormones, and wastes

• Arteries, veins, capillaries: The passage ways where blood travels

14

Digestive System: Receives foods and then breaks down food molecules into simpler forms that will then be absorbed into the internal environment

Consists of : mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gall bladder, pancreas, small intestine, and large intestine

15

Respiratory System: Take air in and out and exchanges gases between the blood and air

Consists of : nasal cavity, pharynx, larynx, trachea, bronchi, and lungs

16

Urinary System: Or Excretory System, removes wastes from blood and assists in maintaining the body’s water and electrolyte balance producing urine

Consists of : kidneys, ureters, urinary bladder, and urethra

17

Reproductive System: Produces whole new organisms like itself- process of producing offspring

Consists of :

Male: scrotum, testes, epididymides, vas deferens, seminal vesicles, prostate gland, Cowper’s gland, urethra, and penis

Female: ovaries, fallopian tubes, uterus, vagina, clitoris, and vulva- supports the development of embryos, carries a fetus to term, and functions in the birthing process
