What else can I help you with?
How does alveoli help two gases diffuse quickly into and out of the blood?
They have capillaries close to their surfaces.
How does pulmonary circulation combines two systems?
The pulmonary circulation works closely with the respiratory system at the alveoli. There, capillaries are in close proximity to the air sacs, and gases are exchanged at this point.
Which two gases are exchanged in the capillaries?
O2 and CO2
How does the respiratory connect to the circulatory?
There is no anatomical connection of circulatory system with the respiratory system. Blood capillaries come in close contact with the lung alveoli. The area of contact is about 1000 square feet. But there are two thin membranes to separate blood and air. The walls of capillaries and the walls of alveoli. Both have flat and thin epithelium. The gases readily pass across these membranes.

How gaseous exchange take place in the alveoli?
We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale? The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth.
How does gas exchange occur in the alveoli?
Gas is exchanged by diffusion. We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths.

They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth. In the alveoli, oxygen crosses over into the blood stream and carbon dioxide leaves the blood stream and enters the alveoli to be expelled through the lungs.
What two important gases diffuse across the respiratory membrane?
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
What order does alveoli lung trachea nose and bronchi go in to reach the blood?
The correct order is:nosetracheamain bronchusbronchi (two) which is part of the lungsbronchioles - tinier than the bronchialveolismall capillaries surround each alveoli and cover each alveoli's surface-- CO2 passes from the alveoli to the venous blood supply; the blood passes O2 to alveoli and into the arterial blood supply
What two gases are exchange among arteries veins and capillaries?
oxygen and carbondioxide
How are oxygen carbon dioxide and other gases exchanged in the lungs and body tissues?
In the lungs, the respiratory zones end in sacs called alveoli, which are the site of gas exchange. The alveoli have walls only one cell thick, and are surrounded by pulmonary capillaries which again have walls only once cell thick; gases diffuse, along their concentration gradients (i.e. from the area of high concentration to the area of low concentration), through these two thicknesses of cells.

What two structures does the exchange of gas occur?
Gas exchange in the respiratory system occurs in the alveoli of the lungs and in the capillaries that surround them. Oxygen from the air diffuses into the bloodstream through the alveoli, while carbon dioxide diffuses out of the bloodstream into the alveoli to be exhaled.
