Which component of blood allows oxygen from the air to move from the lungs to cells of the body?

Respuesta :

The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Answer:

Hemoglobin

Explanation:

Hemoglobin is the protein present in the red blood cells of the blood. The protein hemoglobin serves as oxygen carrier and binds to the oxygen in lungs. As blood flows from lungs to the different body parts, hemoglobin serves to carry oxygen from lungs to various cells of the body.  At higher partial pressure of carbon dioxide and lower pH of cells of the body, the hemoglobin releases oxygen and thereby, serves as oxygen carrier.
