The correct response is:

**exchange oxygen in the air for carbon dioxide in the blood**.

The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs during respiration.
Answered by GPT-4o mini
The correct response is:

**bronchioles**.

Bronchioles are small air passages located within the lungs that branch off from the bronchi and lead to the alveoli where gas exchange occurs.
Answered by GPT-4o mini
The correct response is:

**the alveoli**.

Low blood oxygen levels, despite proper blood circulation, typically indicate an issue with gas exchange in the lungs, which occurs in the alveoli. These structures are responsible for transferring oxygen from the air into the blood and removing carbon dioxide from the blood. If the alveoli are not functioning properly, it can lead to reduced oxygen levels in the blood.

The correct response is:

**It carries deoxygenated blood from the body to the heart.**

The vena cava consists of the superior and inferior vena cava, which are responsible for returning deoxygenated blood from the body back to the right atrium of the heart.
