Question

How is oxygen carried throughout the body?

Question 9 options:

Blood


Nerves


Lungs

Answer 1

Oxygen is primarily carried throughout the body by **blood**. Specifically, red blood cells transport oxygen from the lungs to the tissues and organs. Some oxygen is also dissolved in the plasma, but the majority is carried in the form of oxyhemoglobin, which is formed when oxygen binds to hemoglobin in red blood cells.

So, the answer is **Blood**.
