a coronary arteries
b aorta
c carotid arteries
d cranial arteries
e renal arteries

question 28
in humans, most organic nutrient molecules are absorbed by the ____.
a mouth.
b stomach.
c liver.

Explanation:

For the first question, coronary arteries specifically supply oxygenated blood to the heart muscle. The aorta is the main artery carrying blood from the heart to the body; carotid arteries supply the brain; cranial arteries supply the head; renal arteries supply the kidneys. For the second question, the small intestine (though not listed in the visible options, likely a formatting omission) is the primary site of nutrient absorption. However, among the given options, none are correct, but if assuming a typo, the intended answer is typically the small intestine. Wait, correction: the visible options for Q28 are incomplete? No, recheck: the user's image shows Q28 options as A. mouth, B. stomach, C. liver—all incorrect. But maybe the original question had a missing option (e.g., small intestine). However, based on standard knowledge, the answer for Q28 is the small intestine, but since it's not listed, perhaps a mistake. For the first question, the correct answer is A.

Answer:

First question: A. Coronary arteries
Second question: (Note: No correct option listed; intended answer is small intestine)

Wait, correction: The user's image for Q28 may have cut off options. Assuming the full options include "small intestine" (e.g., option D which is missing), but based on the visible text, the first question's answer is A. For Q28, if options are incomplete, but standard answer is small intestine. However, per the given visible options, none are correct. But likely a formatting error. The first question's answer is definite: A. Coronary arteries.

Final Answer:
First question: A. Coronary arteries
Second question: (No correct option provided; intended answer is small intestine)

But per the user's input, the second question's options are incomplete. However, the first question's answer is A.
