Question

lo 3.3. what happens to deoxygenated blood in the lungs? it remains deoxygenated and releases carbon dioxide it picks up oxygen and releases carbon dioxide it becomes oxygenated and picks up carbon dioxide it picks up carbon dioxide and releases oxygen it releases oxygen and picks up carbon dioxide

Explanation:

Deoxygenated blood travels to the lungs. In the alveoli of the lungs, through the process of gas exchange, oxygen diffuses into the blood (so it picks up oxygen) and carbon dioxide (a waste product from cellular respiration) diffuses out of the blood into the alveoli (so it releases carbon dioxide). This converts deoxygenated blood to oxygenated blood which then returns to the heart to be pumped to the rest of the body.

Answer:

It picks up oxygen and releases carbon dioxide.
