Why does air sacs need rich supply of blood vessel?
Air sacs need a rich supply of blood vessels to facilitate diffusion. A large number increases the surface area available to pick up oxygen and get rid of CO2.
Which substances are exehanged between the blood in the capillaries and the air in the air sacs?
Oxygen moves into the capillaries from the air sacs. Carbon dioxide moves out the the capillaries into the air sacs.
Air that leaves the air sacs is rich in the gas?
Oxygen is 'transported' from the lung capillaries to the body capillaries - in an inverse fashion carbon dioxide is transported from the body capillaries to the Lung Alveoli - the Answer is 'It is rich in CO2."
Where in the lungs does diffusion take place and what gasses are diffused?
---------------------------- The exchange of gasses takes place across the Alveoli, which are air spaces surrounded by very small air sacs and have a rich supply of blood, because they are surrounded by capillaries. The lungs are made up of many alveoli which are the respiratory surface. Oxygen diffuses from the alveoli into the blood in the capillaries and carbon dioxide diffuses from the blood in the capillaries into the alveoli.
What is the name of the organ that you use to breathe in oxygen?
the air goes into your lungs. In your lungs there are billions of tiny air sacs. Surrounding each air sac is a network of blood capillaries. The air sacs and the blood capillaries are separated by a thin membrane. Across this membrane the air sacs give the blood capillaries oxygen and they blood capillaries give the air sacs carbon dioxide. We breathe out this carbon dioxide!
What sort of blood vessels are surrounding the air sacs in your lungs?
Capillaries are the blood vessels that surround the alveoli, or air sacs, in your lungs. These capillaries are the site of gas exchange.
What are the tiny blood vessels that wrap around the air sacs?
Capillaries . The smallest of the blood vessels: capillaries.
What are tiny air sacs surrounded by capillaries?
Alveoli.
What the capillaries around the air sacs take in?
carbon dioxide
Oxygen diffuses into the capillaries of the lungs because there is a?
greater concentration of oxygen in the air sacs of the lungs than in the capillaries.
How do the circulatory and respiratory system work together in the air sacs?
The lungs bring air into the air sacs, which are tightly wrapped with capillaries. The capillaries exchange oxygen for carbon dioxide, which the lungs expel.
What are the small tubes called that carry air to the air sacs?
Capillaries.
