Answer to Question 1

C
Feedback:
Cholinergic agonists are drugs that increase the activity of acetylcholine receptor sites throughout the body. Dopamine, GABA, and norepinephrine are not associated with cholinergic agonist function.

Answer to Question 2

D
Feedback:
Oxygenated blood from the lungs enters the left atrium through the pulmonary veins and passes through the mitral valve into the left ventricle, which contracts and ejects blood through the aortic valve into the aorta and out to the systemic circulation.
