What else can I help you with?
Exchange of nutrients and gases between the blood and tissue cells?
This process occurs through the capillaries. Nutrients and oxygen diffuse from the blood into the tissues, while waste products and carbon dioxide diffuse from the tissues into the blood. This exchange is facilitated by the thin walls of the capillaries and the high surface area for diffusion.
How does alveoli help two gases diffuse quickly into and out of the blood?
They have capillaries close to their surfaces.
What does the alveoli and blood capillaries have in common?
they are both one cell thick to let the gases diffuse
What are blood vessels called that surround the nephron loop?
Renal capillaries, aka the glomerulus, where nitrogenous wastes and excess water in the blood plasma diffuse over to the nephron to be filtered and excreted.
Will O2 diffuse from air to blood or from blood to the alveolar air?
It will be absorbed from the air into your lungs. Then when it reachs the alveolus it will diffuse from the alveolus into the blood capillaries down an oxygen concentration through diffusion where it will combine with the heamoglobin in the Red Blood Cells.
Which way would O2 and CO2 diffuse during internal respiration?
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
What blood vessels do the exchange of gases occur?
the blood vessel which allows gas exchange to occur is the capillaries
The movement of nutrients into the bloodstream?
Absorption is the process by which nutrients are moved into lymph and blood.
Do alveoli have C shaped rings around them?
Alveoli are surrounded by capillaries so that the oxygen can diffuse into the blood and carbon dioxide can diffuse out. I think it depends on the shape of the alveoli to the path of the capillary.
What kind of blood vessels allow substances to enter and leave the blood easily around the cells?
Capillaries. they have such thin walls that substances can easily diffuse through them.
Where does carbon dioxide diffuse into the blood during the process of respiration?
Carbon dioxide diffuses into the blood in the capillaries surrounding the alveoli in the lungs during the process of respiration.
Why do you need capillaries?
Arteries carry blood to the tissues, and veins carry blood back to the heart. In betweenare tiny blood vessels so small that red blood cells can pass through single file, allowingthe oxygen to diffuse into the surrounding tissue. These are called capillaries.
