Question

normally, the partial pressure of oxygen gas is higher in the
multiple choice
alveoli
bronchioles
venous blood
blood of the pulmonary capillaries

Explanation:

The alveoli are the site of gas exchange in the lungs. Oxygen from the inhaled air enters the alveoli. Due to the process of gas exchange (diffusion), oxygen moves from an area of higher partial pressure (alveoli) to an area of lower partial pressure (pulmonary capillaries). Venous blood has a lower partial pressure of oxygen as it is returning to the lungs to pick up oxygen. Bronchioles are just air - conducting passages and do not have a higher partial pressure of oxygen compared to alveoli in the context of gas exchange.

Answer:

alveoli
