What else can I help you with?
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.
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 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.
Where in the human body is the highest concentration of capillaries?
The lungs of course
Which are the areas of gas exchange?
the alveoli in the lungs and the capillaries in the body
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 is the oxygen enters the blood?
Oxygen enters the blood through the process of respiration in the lungs. In the lungs, oxygen diffuses from the alveoli into the blood capillaries surrounding them. It then binds to hemoglobin in red blood cells for transport to tissues throughout the body.
Are capillaries cells?
No, capillaries are tissues that form tubes to transport blood throughout the body. They are made of thousands of cells.
What epithelial tissues form walls of capillaries and air sacs of lungs?
Simple squamous epithelium.
What needs to pass oxygen from lungs to blood vessels?
The alveoli in the lungs are where oxygen is exchanged with carbon dioxide. Oxygen diffuses across the alveolar walls and into the capillaries where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
What organs supply blood with oxygen in mammals?
the lungs supply the blood with oxygen, within the lungs there are alveoli which have a very thin membrane which allows oxygen to pass into the capillaries that run into the lungs hope i helped
How does oxygen reach to the tissues?
Oxygen is transported to the tissues by red blood cells through the circulatory system. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to the tissues throughout the body. At the tissue level, oxygen diffuses from the capillaries into the surrounding cells for cellular respiration.
