Detailed explanation-1: -Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation.
Detailed explanation-2: -Things like water, proteins, hormones, nutrients (glucose, etc), waste products (ammonia), gases (oxygen, carbon dioxide), electrolytes, etc must all be readily exchanged across our capillaries. Most of these things are dissolved in our blood plasma. How exactly do they move across wall of the capillaries?
Detailed explanation-3: -Capillaries. The arteries eventually divide down into the smallest blood vessel, the capillary. Capillaries are so small that blood cells can only move through them one at a time. Oxygen and food nutrients pass from these capillaries to the cells.
Detailed explanation-4: -Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.
