capillaries are the site of exchange of materials where the needed substances in the tissue diffuse into them from the capillary through diffusion.while the metabolic wa
ste from tissues diffuse into the capillary and taken away.the capillaries have a big surface area and their cells is one cell thick to enable diffusion to take place fast.

What does Gas exchange that occurs between the capillaries and the oxygen-starved tissues is specifically known as?
The gas exchange that occurs between the capillaries and oxygen-starved tissues is specifically known as "internal respiration." During this process, oxygen is delivered from the blood in the capillaries to the tissues, while carbon dioxide produced by the tissues is absorbed into the blood. This exchange is crucial for cellular metabolism and maintaining homeostasis within the body.
Oxygen and carbon dioxide exchange between the circulatory system and tissues occurs at the?
oxygen and carbon dioxide exchange between the circulatory system and tissues occurs at the capillaries, which are the smallest blood vessels where nutrient and gas exchange takes place through diffusion. Oxygen from the blood is released into the tissues, and carbon dioxide from the tissues is taken up by the blood to be transported back to the lungs for elimination.
Capillaries exchange food oxygen and what?
They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.
What Are sites of exchange between blood and tissue?
The capillaries are the primary sites of exchange between blood and tissues. Capillaries are small blood vessels with thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. These exchanges are essential for maintaining the proper function of tissues in the body.
What is The site of gas exchange in the tissues?
The site of gas exchange in the tissues is the capillaries. Here, oxygen from the red blood cells is released into the tissues, while carbon dioxide from the tissues enters the blood to be carried away. This exchange occurs due to differences in partial pressures of gases between the blood and the tissues.
Exchange of gases occurs between capillaries and what structure?
Exchange of carbon-di-oxide for oxygen takes place between capillaries and tissues.The exchange of gases occur through diffusion.In Lungs, oxygen from inhaled air in the alveolar space moves into the RBCs in the capillaries and the carbon-di-oxide moves form the RBCs in the capillaries to the alveolar space which is exhaled during respiration.In other tissues, the Oxygen is given to the tissues and carbon-di-oxide is taken from the tissues into the blood.Many gases can be exchanged across the capillaries but the exchange of oxygen and carbon-di-oxide occurs normally in the body.
Where does most gas exchange between blood and tissue take place?
Most gas exchange between blood and tissues takes place in the capillaries. This is where oxygen diffuses from the blood into the tissues, and where carbon dioxide diffuses from the tissues into the blood. The thin walls of the capillaries allow for efficient exchange of gases.
What is the difference between the two types of respiration?
External respiration refers to the exchange of gases between the lungs and the blood, while internal respiration is the exchange of gases between the blood and the tissues. External respiration involves the intake of oxygen and release of carbon dioxide in the lungs, while internal respiration occurs in the body's tissues.
What stimulates blood to release oxygen to tissues?
Hemoglobin within red blood cells binds with oxygen in the lungs and releases it to tissues when the blood reaches areas with lower oxygen concentration. This process is driven by the difference in oxygen concentration between the blood and the tissues, known as the oxygen gradient. Additionally, factors such as increased metabolic activity, carbon dioxide levels, and acidity in the tissues can also influence the release of oxygen from hemoglobin.
What system is a group of organs and tissues that exchange oxygen and carbon dioxide?
chloplast
The exchange of oxygen and carbon dioxide between systemic capillaries and tissue cells is called?
The exchange of oxygen and carbon dioxide between systemic capillaries and tissue cells is called external respiration. Oxygen is taken up by the blood in the capillaries and delivered to the tissues, while carbon dioxide is picked up from the tissues by the blood to be removed from the body.
What is the main function of the capillares?
Capillaries are tiny blood vessels that connect arteries and veins. Their main function is to allow for the exchange of nutrients, oxygen, and waste products between the blood and surrounding tissues. This exchange is essential for the proper functioning of organs and tissues in the body.
