4 g. Heart Diagram Use arrows to show the pathway of blood flow. Use blue and red to represent whether the blood is oxygenated (red) or deoxygenated (blue). h. List the flow of blood through the heart using the four chambers of the heart and their arteries. 7. Respiratory System a. Respiration of an organism is the exchange of and gases. b. In what two locations does gas exchange occur? c. How does your muscular system help out your respiratory system? 8. Digestive System a. The digestive system breaks down food to get the molecule which is delivered to the muscles by the system.

5 b. Define peristalsis: c. How does the Nervous System help the Digestive System? 9. Excretory System a. What is the purpose of the Excretory System? b. The lungs rid the body of. c. The skin rids the body of. d. Reviewing questions b & c above, what two body systems, besides Excretory, are involved in excretion of wastes? 10. Endocrine System a. The main function of the endocrine system is to regulate body processes through chemicals called, which are produced by glands. b.

A long distance runner needs plenty of energy, which requires oxygen to produce. What two systems work together to provide the oxygen and movement for this runner? h. Explain how the immune system and integumentary systems provide protection.

7 i. Adrenaline is a hormone released when your body is under stress from a perceived threat. Explain which three systems would be working together to (1) secrete this hormone, (2) ensure that it s transported throughout your body, and (3) allows you to run away from the danger. j. The stem of a plant provides structure for the plant, in addition to having vascular tissue to transport water, nutrients and glucose. What two systems would provide these functions in humans? 14.
