There are two ways in which the body produces energy.
It can do it in two ways:
Aerobic ( Oxygen + Glucose -> Carbon Dioxide + Water Vapour + Energy) respiration and anaerobic respiration ( Glucose -> Lactic acid + Carbon Dioxide. The body usually uses aerobic respiration when there is enough oxygen because aerobic respiration produces more energy. However, when you are sprinting or doing something similar, anaerobic respiration is used when the supply of oxygen is not as large as the demand. Anaerobic respiration produces less energy and lactic acid is produced causing cramps in muscles and possibly more serious problems.
If humans only held oxygen in the blood and had no access to oxygen, brain activity would only happen for 15 seconds before blacking out. In three minutes with zero oxygen your brain would die.
Blood supplies oxygen and nutrients to all parts of the body.
If a person has a blood condition or disease that affects the ability of red blood cells to deliver oxygen to cells of the body, they may experience symptoms such as fatigue, shortness of breath, weakness, and pale skin. These symptoms occur due to insufficient oxygen supply to the body's tissues and organs, leading to a lack of energy and impaired functioning of various bodily systems. Prompt medical attention and treatment are crucial in managing such conditions.
To the contrary, oxrgen cycels through your lungs and enters your blood. you use oxygen every second and you need a constant supply of it. As you lack oxygen your body starts to shutdown what isn't needed to keep you alive until your oxygen or blood oxygen is out.

The left side of the heart is responsible for pumping oxygen-rich blood out to the body through the aorta, so that it can deliver oxygen (O2) to the tissues and organs. This side receives oxygenated blood from the lungs and pushes it out to the rest of the body.
Blood, oxygen, and nutrients.
Blood delivers oxygen.
Oxygen
Blood delivers oxygen.
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
To supply blood with oxygen so the blood can deliver the oxygen throughout the body.
Blood supplies oxygen and nutrients to all parts of the body.
Hemoglobin, a protein found in red blood cells, helps deliver oxygen to the blood by binding to oxygen molecules in the lungs and releasing them to tissues throughout the body. Additionally, the respiratory system's process of inhaling oxygen and exhaling carbon dioxide facilitates the transfer of oxygen into the bloodstream.
oxygen and nutrients all over the body

No, the red blood cells carry oxygen.
