Capillaries
Blood passes through the capillaries, which provide a passage way for the blood from the arteries to the veins. The tiny, thin walled capillaries also allow for the exchange of gases through the tissue. You can read more about capillaries at fi.edu
the blood vessel which allows gas exchange to occur is the capillaries
Capillary.capillariesCapillaries.Blood flow moves from arteries, to arterioles, to capillaries, to venules, to veins, to the heart, and then back to arteries. Capillaries are where the exchange of oxygen and other materials happens.Capillaries
Exchange among subdivisions of the extracellular fluid (ECF) occurs primarily at the capillaries, where nutrients, gases, and waste products are exchanged between the blood and interstitial fluid. This exchange is facilitated by the thin walls of capillaries and the pressure differences between the blood and surrounding tissues.
When blood leaves the small arteries and enters the capillaries, the pressure drops significantly. Typically, the systolic blood pressure in small arteries can be around 80-120 mmHg, but by the time blood reaches the capillaries, the pressure usually falls to about 30 mmHg or lower. This decrease is crucial for allowing the exchange of nutrients, gases, and waste products between blood and surrounding tissues. The lower pressure in capillaries helps facilitate this exchange effectively.
Exchange between tissues and blood primarily occurs in the capillaries, not in arteries and veins. Arteries transport oxygenated blood away from the heart under high pressure, while veins carry deoxygenated blood back to the heart. The walls of arteries and veins are too thick and impermeable to allow for the diffusion of nutrients, gases, and waste products. Only the thin-walled capillaries facilitate this exchange due to their close proximity to tissue cells.
When the right ventricle contracts it is pushes blood to the pulmonary arteries and to the capillaries of the lungs where exchange of gases takes place
