Answer to Question 1

Blood enters from the superior and inferior vena cavae and flows into the right atrium. It flows through the tricuspid valve into the right ventricle, which pumps it through the pulmonary semilunar valve into the left and right pulmonary arteries, which carry it to the lungs. From the lungs, the blood flows through the pulmonary veins, which carry the blood to the left atrium. The blood then flows through the mitral valve into the left ventricle, which pumps the blood out through the aortic valve and into the aorta.

Answer to Question 2

A
Explanation:
A) Correct.
B) A comedo is a blackhead.
C) A corn is a hardened thickening of the skin.
D) A cyst is a closed, fluid-filled sac.

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
