Answer:
The correct answer is A, as the statement is true. All blood returns to the heart by way of either the superior vena cava or the inferior vena cava.
Explanation:
The heart pumps blood to all parts of the body. Blood supplies oxygen and nutrients to the entire body and removes carbon dioxide and residual elements. As blood travels through the body, oxygen is consumed and blood becomes deoxygenated.
Deoxygenated blood returns from the rest of the body to the heart through the superior vena cava and the inferior vena cava, the two main veins that carry the blood back to the heart.

P wave is the atria “firing”/depolarizing, the QRS complex is the ventricles depolarizing (and the atria are depolarizing while this happens), and the T wave is the ventricles depolarizing. Depolarizing is when it contracts, and repolarizing is when it relaxes and refills.
Answer:
The correct answer is a. elevated ADH levels
Explanation:
The function of ADH is to regulate the excretion of water from kidneys. As Dan has been lost in the desert for 2 days his body must be dehydrated and in stress which gives signal to hypothalamus gland to increase ADH level.
Once ADH level is increased his kidney starts reabsorbing as much water as it can preventing his body to become dehydrated and reduce his urine amount.
So the correct answer is a. elevated ADH levels
