GENERAL HISTOLOGY

Detailed explanation-1: -Oxygen moves from the capillary toward the cells of the tissues and organs. Carbon dioxide moves from the cells and into the capillaries. Blood leaves the capillary and enters the small venules. These venules become progressively larger vessels called veins.

Detailed explanation-2: -The exchange of oxygen, nutrients, and waste between your blood and tissues also happens in your capillaries. This happens through two processes: Passive diffusion. This is the movement of a substance from an area of higher concentration to an area of lower concentration.

Detailed explanation-3: -Diffusion transports fluids, gases, nutrients, and wastes between the blood and body tissues through capillaries. Fluid travels from the vessel to the bodily tissue as a result of this process. The blood pressure in the vessel equals the osmotic pressure of the blood in the vessel in the center of the capillary bed.
