DIRECTIONS: Chose the letter of the correct answer. Write the chosen letter on a separate sheet of paper.

1. Which of the following is an example of the endocrine system directly interacting
A. Hormones provide feedback that affects neutral processing
B. The vertebrae protect the spinal cord from injury
D. The brain sends signals that control the speed at which food moves through
C. Sensory receptors in bones send signals about body position to the brain

2. During the final stages of human gestation, receptors for the hormone oxytocin
increase on the smooth muscle cells of the uterus. The release of the oxytocin
during labor stimulates the smooth muscle tissue in the wall of the uterus. The
vigorous contraction of the uterine smooth muscle helps push the baby through
the birth canal so that delivery can occur. This process involves the interaction

3. Kidneys are part of the excretory system. They purify the blood and send it back
Assessment
of which organ system?
A. Endocrine and reproductive only
B. Endocrine and muscular only
C. Endocrine, muscular and reproductive
D. Endocrine, reproductive, and excretory
to the rest of the body. Which system is mainly responsible for the transport of
plasma to the kidneys?
A. Circulatory systems
B. Respiratory systems
C. Nervous systems
D. Muscular systems

4. What two body systems are most useful in getting nutrients from the food that
you eat?
A. Muscular and endocrine systems
B. Nervous and digestive system
C. Nervous and circulatory systems
D. Circulatory and digestive systems

5. What two systems work together to provide body cells with a constant supply of
oxygen while removing carbon dioxide waste?
A. Circulatory and respiratory systems
B. Muscular and circulatory systems
C. Nervous and circulatory systems
D. Nervous and immune systems​

6. Which of the following describes an interaction that occurs between two body
systems of a rabbit that helps the rabbit outrun a pursuing coyote?
A. The endocrine system releases hormones that prepare the immune system to
deal with the possible injuries.
B. The digestive system increases the rate of digestion, and the excretory system
ceases to provide tissues with more nutrients
c. The respiratory system increases the breathing rate, and the circulatory
system increases blood pressure to provide tissues with more oxygen
D. The skeletal system releases additional calcium, and the circulatory system
retains more sodium in the blood to provide muscles with ions for contraction

7. The human digestive system id approximately 900 cm long. Food is moved
through the digestive tract primarily by:
A. Bile produce by the pancreas
B. Hydrochloric acid by the stomach
C. Muscular contractions
D. The enzyme amylase and pepsin

8. The digestive system is to absorbing nutrients as the circulatory system is to
A. removing nutrients
B. attracting nutrients
C. disturbing nutrients
D. fighting infections

9. How do circulatory system and immune system work together to respond to an
injury?
A. Increase blood flow carries white blood cells to the site of the injury
B. Increase blood flow kills healthy cells which prevents infection at the site of
the injury
C. Increase blood flow allows for an increase in the exchange of carbon dioxide
and oxygen at the site of the injury
D. Increase blood flow removes infected cells from the body at the site of the
injury

10. Which body systems must directly interact for vertebrate organism to exchange
gasses?
A. Circulatory and respiratory
B. Endocrine and respiratory
C. Immune and endocrine
D. Skeletal and circulatory

11. A deer hears a predator approaching and begins to run for safety. The deer has
primarily engaged what body system to escape?
A. Muscular, reproductive and circulatory system
B. Muscular, digestive, and immune system
C. Nervous, respiratory, and muscular system
D. Respiratory, endocrine and excretory system​

vomit it uses as a defense?
A. Excretory and immune
B. Muscular and digestive
C. Nervous and digestive
D. Urinary and muscular

13. Which of the following is an example of the endocrine system directly
interacting with the nervous system?
A. Hormones provide feedback that affect neuron processing
B. The brain sends signal that control the speed at which food moves through
the intestines
C. The vertebrae protect the spinal cord from injury
D. Sensory receptors in bones send signals about body position to the brain.

14. Which body systems work together to protect the body from pathogens?
A. Circulatory and immune
B. Digestive and excretory.
C. Endocrine and reproductive.
D. Muscular and vascular

15. How does the digestive system work with all other systems?
A. The digestive system transport blood to all the other systems
B. The digestive system puts oxygen into the body
C. The digestive system gives the body energy and nutrients
D. The digestive system allows the body to move​​
