Question 16 • 2026-2027 EDGE Human Anatomy and Physiology B

After blood leaves the heart through the aorta, what happens? Check all that apply.

Answer
A
The blood moves through the cells of the body delivering oxygen.
B
The blood moves into the lungs.
C
The blood moves through progressively smaller blood vessels.
D
The blood removes carbon dioxide and other wastes from the cells.
E
The blood moves only to the upper part of the body.

Explanation

Blood leaving the heart through the aorta travels through arteries that branch into progressively smaller blood vessels, eventually reaching the body’s cells. There it delivers oxygen and picks up carbon dioxide and other wastes. It does not go directly into the lungs, and the aorta supplies the whole body, not only its upper part.
