Substances move down their concentration gradient. By that I mean where they move from an area of high concentration to an area of low concentration. This is essentially diffusion. Nutrients like glucose or oxygen that are high in the blood but low in the tissues, diffuse from the blood into the tissues. Wastes like carbon dioxide which are high in the tissues but low in the blood, diffuse from the tissues into the blood.
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
The area where chemicals pass between cells and blood is called the interstitial space. This space contains fluid that surrounds the cells and allows for the exchange of nutrients, waste products, and signaling molecules between the blood and the cells.

CO2 exchanged to blood through capillaries and blood to alveoli
Those tiny and beautiful blood vessels are called as capillaries. You have millions of them in your body. The nutrition and oxygen is given out, at the proximal end. The metabolic wastes and carbon bi oxide in taken in, at the distal end.
diffusion: particles move from a high concentration to a low concentration
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.

alveolus
Yes, oxygen is transferred to the blood via aveolae in the lungs.
Capillaries are the small blood vessels where oxygen is exchanged for carbon dioxide. They are located throughout the body and allow for the exchange of gases between the blood and tissues.

describe the differences between intravenous fluid and blood
Oxygen, nutrients, waste products, hormones, and electrolytes are exchanged between the body cells and the blood plasma. This exchange occurs through the capillaries that connect the circulatory system with the cells in the tissues. Oxygen and nutrients are delivered to the cells, while waste products and carbon dioxide are removed from the cells and transported back to the excretory organs for elimination.
