Where do red blood cells drop off oxygen?
Red blood cells release their oxygen in the capillaries. The oxygen diffuses across the capillary wall to reach the body tissues.
What is the role of the capillaries?
Capillaries are very small blood vessels found within the tissues of the body. Its primary role is to transport blood from arteries to the veins.
Which are the areas of gas exchange?
the alveoli in the lungs and the capillaries in the body
Where in the human body is the highest concentration of capillaries?
The lungs of course
Are capillaries cells?
No, capillaries are tissues that form tubes to transport blood throughout the body. They are made of thousands of cells.
The transport of oxygen by hemoglobin occurs in the?
capillaries between the cells in the lungs or the capillaries between the cells in the body
What epithelial tissues form walls of capillaries and air sacs of lungs?
Simple squamous epithelium.
What blood vessel changes blood from oxygenated to deoxygenated?
The capillaries carry oxygenated blood from the arterioles through body tissues, where the oxygen diffuses into cells that need it. The capillaries then receive carbon dioxide from the cells, and enter the venules that lead to veins.
What are tiny vessels which diffusion takes place between the blood and the body tissues?
The capillaries. Check Wiki for "Capillary action".
What is the major function of the lungs in a human body?
The major function of the lungs is gas exchange. Gas exchange requires the entire cardiopulmonary system which includes the heart, lungs, and blood vessels (arteries,arterioles,capillaries,veins),. At the capillaries which is the smallest vessels with thin walls permitting diffusion and gas exchange the carbon dioxide (C02) and oxygen (02) are exchanged. It is the capillaries that allows tissues to be supplied with the essential oxygen that they need and allows the tissues get rid of the toxic waste products including C02. The waste products will travel back to the veins, back to the heart where they then go to the lungs and are expired. When an individual inhales, the oxygen is taken in via alveoli in the lungs, travel to the heart then to the arteries and then to the tissues. and the cycle continues...
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.
What are the tiny vessels through which diffusion takes place between the blood and the body tissues?
The capillaries. Check Wiki for "Capillary action".
