Answer 2

Answer: Blood picks up oxygen primarily in the lungs.

Explanation: The respiratory system refers to the anatomical structures and physiological processes involved in the exchange of oxygen and carbon dioxide between the body and the environment.

Blood picks up oxygen primarily in the lungs. When we inhale, oxygen enters the lungs and diffuses into the tiny air sacs called alveoli. Within the alveoli, oxygen molecules bind to hemoglobin in red blood cells, forming oxyhemoglobin.

This oxygen-rich blood is then carried by the circulatory system to deliver oxygen to tissues throughout the body. The heart pumps the oxygenated blood to the rest of the body, but it is the lungs where the actual exchange of oxygen occurs. The intestines, on the other hand, play a role in absorbing nutrients from digested food but are not directly involved in oxygenation of blood.
