Which part of the body has thin walls to allow oxygen to pass through?
Capillaries
Inhaled oxygen diffuses through the walls of what?
Inhaled oxygen diffuses through the walls of the alveoli in the lungs into the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport to tissues in the body.
How does the oxygen you inhale travel into your cells?
When you breathe it in the oxygen runs around your body and passes through the walls into your blood stream
What is the correct order of the following - 'a' oxygen rich blood arrives at capillaries - 'b' oxygen enters body cells - 'c' heart pumps oxygen rich blood - 'd' oxygen moves through capillary walls?
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.
Why does the walls of the capillaries and the alveoli have to be thin?
If their walls are too thick, substances like oxygen and nutrients and waste cannot pass across the cells into or out of the body.
Have very thin walls to allow exchange of materials between blood and body cells?
Capillaries have cell walls that are onlt one cell thich to allow nutrients to pass through and into the body cells and back again. I hope this helps :-)
What happens when oxygen and carbon dioxide are exchanged in the lungs?
The exchange of oxygen and carbon dioxide happens in between the alveoli and then through the walls of the capillaries and then into the blood. The oxygen is then picked up by hemoglobin in the red blood cells and sent to all body cells. While this is happening the carbon dioxide is transported back from the body cells and into the blood. It diffuses through the walls of the capillaries and into the walls of the alveoli. Carbon dioxide leaves your body whenever you breathe out.
How do leech breathe?
They breathe through their body walls. Leeches absorb oxygen through their skin rather than breathing through a nose.
During respiration the exchange of gases takes place through the walls of the what?
During respiration the exchange of gases takes place through the walls of the alveoli. From there, the oxygen is taken by the blood to the body tissues.
Why exchange of substances blood and cells take place through capillaries?
Capillaries have thin and permeable walls which allow the exchange of substances (such as nutrients, oxygen and CO2) to occur. This enables substances to dissociate throughout the entire body (as capillaries are present throughout the entire body).
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Why capillaries have a single layer of epithelial cells?
it is because for the diffusion of water and oxygen molecules
