2. Identify structure B. What kind of digestion occurs here?
3. What is the function of structure A?
•liver •to produce bile
•stomach
The esophagus pushes food down into the stomach using peristalsis.
•chemical digestion

1.Which organs are not part of the gastrovascular tract? How do they aid in digestion?
Esophagus (A)Stomach (B)
Small intestine (D)
•Liver (F) – produces bile that goes to the SI•Gall bladder (E) – stores bile•Pancreas (C) – releases pancreatic juice into SI
Describe the role of the small intestine in digestion.
•Where most chemical digestion occurs
•Where chemical digestion is completed
•Lined with VILLI which absorb nutrients into the blood
Identify the labeled organs.

Which part of the human blood:
1. is the most numerous?
2. contains a nucleus?
3. is biconcave?
4. is produced in the bone marrow?
5. consists mainly of water?
wbc’srbc’s
rbc’s, wbc’s, platelets
rbc’s
plasma
Which activity is not a function of white blood cells in response to an invasion of the body by bacteria?
1. engulfing these bacteria
2. producing antibodies to act against this type of bacteria
3. preparing for future invasions of this type of bacteria
4. speeding transmissions of nerve impulses to detect these bacteria
Which part of the human blood transports hormones and nutrients?
1. plasma
2. platelets
3. red blood cells
4. white blood cells
The breaking apart of platelets in the blood helps in the
1. synthesis of hemoglobin
2. formation of a clot
3. release of antibodies
4. deamination of amino acids
Explain the difference between arteries and veins.
•Arteries carry blood AWAY from heart. Veins carry blood to the heart.
•Arteries are larger, more muscular and elastic than veins.
•Arteries carry blood under higher pressure than veins. •Veins have valves to prevent the backflow of blood. Arteries do not have valves.
Explain what occurs in capillaries and why.
The exchange or diffusion of substances into or out of the capillary.
Capillaries are extremely small and have a VERY thin lining that allows for diffusion to occur.

The diagram represents a capillary near some cells. 1. Identify the substances diffusing out of the capillary and into cells. 2. Identify the substances diffusing out of cells into the capillary.
Blood normally flows from the capillaries directly into
1.small arteries
2.small veins
3. lymph vessels
4. heart atria
The movement of blood from the legs toward the heart is hindered by gravity. The effect of gravity is counteracted by
a. smooth muscle in the capillaries
b. cilia lining the blood vessels
c. valves in the veins
d. lymph nodes near major vessels
Which statement best describes arteries?
a. They have thick walls and transport blood away from the heart.
b. They have thick walls and transport blood toward the heart.
c. They have thin walls and transport blood away from the heart.
d. They have thin walls and transport blood toward the heart.
1. Identify the upper chambers of the heart.
2. Identify the lower chambers of the heart.
3. Identify the structures that separate the upper and lower chambers.
4. Identify the wall that separates the right and left side of the heart.
Right and left atria
Right and left ventricles
valves
septum
When blood passes through the heart from the left atrium (D) to the left ventricle (E), it must first pass through a
valve
Identify the part of the heart being described.
1. Chamber that receives oxygenated blood.
2. Wall that separates the right and left side of the heart.
3. Large artery that carries oxygenated blood to the rest of the body.
4. Chamber that pumps out deoxygenated blood.
Left atrium
Septum
Aorta
Right ventricle
5. Chamber that receives deoxygenated blood.
6. Prevents the backflow of blood between atria and ventricles.
7. Chamber that pumps out oxygenated blood.
Right atrium
Valves
Left ventricle
