• Excretory

• Nervous

• Respiratory

Which two body systems carry signals from one part of the body to another part?

• Circulatory

• Digestive

• Excretory

• Nervous

• Urinary

When a person's heart and breathing rate increase while running a race, what does this help a person do?

• Increase the rate of digestion

• Decrease the rate of gamete production

• Decrease the rate of protein synthesis in neurons

• Increase the rate of cellular respiration in mitochondria

Valvular stenosis is a condition in which the heart valves are stiff and do not open completely. In people with this condition, blood flow to the body is decreased.  How will valvular stenosis most likely affect body cells?

• Body cells will produce less water than usual

• Body cells will receive less oxygen than usual

• Body cells will store more nutrients than usual

• Body cells will produce more waste products than usual

Which of the following happens as a result of decreased liver function?

• Toxic compounds build up in the blood

• Carbon dioxide builds up in the liver

• The kidneys take over the functions of the liver

• The stomach produces the enzymes needed for digestion

Most people are born with two kidneys. However, it is possible to live with only one kidney. Doctors recommend that people with one kidney have their urine tested at least once a year.

Which of the following are doctors most likely trying to determine when testing the urine of a person with only one kidney?

• That enough nutrients are dissolving in the blood

• That enough nitrogenous waste is being removed from the body

• That enough red blood cells are being replaced in the blood

• That enough oxygen is being delivered throughout the body

Match the following evens that occur in each part of the digestive system.
