nutrients
Air is brought into the body during respiration, and oxygen is absorbed by the hemoglobin of the red blood cells in the lungs by diffusion. Carbon dioxide is removed during respiration -- without the removal of the CO2, the oxygen wouldn't get in.

white blood cells
Oxygen is carried by the red blood cells. The hemoglobin in the blood mixes with oxygen, and this is transported to other parts of the body.
The digested food is in form of glucose which is broken down in mitochondria to release energy.
The bloodstream carries nutrients to the body's cells. Nutrients from the food we eat are absorbed in the digestive system and then transported via the bloodstream to cells throughout the body, providing them with the necessary energy and building blocks for proper functioning.
Hemoglobin is the substance in the blood responsible for carrying oxygen to the tissues. It is a protein found in red blood cells that binds to oxygen in the lungs and releases it to the body's tissues and organs.
Hemoglobin is the substance in red blood cells that carries oxygen. It is a protein that binds to oxygen in the lungs and releases it to tissues throughout the body.
Oxygen enters the body by being absorbed into the blood (specifically, it is absorbed by red blood cells which contain an oxygen-carrying compound known as hemoglobin) when air is inhaled into the lungs, which have a highly porous, spongy structure which facilitates the exposure of blood to the air.
Red blood cells absorb oxygen and release carbon dioxide at lungs which was absorbed from other cells in the body during blood circulation, then it releases oxygen to those body cells in order to respire and release energy .
Red blood cells carrie oxegen to the different parts of your body allowing you to function and live.
Blood cells are produced from bone marrow. This is gel like substance that is located inside the bone.
