In the lungs is carbon dioxide more concentrated in the alveoli or in the blood?
In the lungs, carbon dioxide is concentrated more in the blood. The alveoli keeps the carbon dioxide at a lower level than in the blood.
Why do blood capillaries surround alveoli?
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
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
Is Pco2 is greater in the alveoli than it is in the arterial end of pulmonary capillaries?
No. Once blood reaches the alveoli it will immediately start to release CO2 to the air in our lungs and absorb O2 from the air in our lungs. This means that the PCO2 will be higher in the blood of the pulmonary artery than in the blood of the alveolus. If this were not so, then passing blood through the alveoli would be pointless.
Ventilation perfusion coupling means that more blood flows past functional alveoli than past nonfunctional alveoli?
True.
How does oxygen enter the alveoli then into the lungs after it enters the red blood cells?
The oxygen enters the aveoles because when you breath you create a vaccum and the oxygen rushes in to fill the empty space. it enters the red blood cell by difusing through the aveole and then travels throughout the body.
What is the type of transport that oxygen move from the alveoli into the pulmonary capillary blood?
Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.
Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
Is o2 concentration greater in the pulmonary capillaries or alveoli?
In the alveoli
What is a function of a respiratory system?
Human respiration, as a person takes a breath in the air rushes into the lungs causing the alveoli to expand. The alveoli are like little balloons with air on the inside and tinny blood vessels, called capillaries, surrounding the outside. The lungs expand as the alveoli fill up with air. The concentration of oxygen in the air of the alveoli is higher than the concentration of oxygen in the blood inside the capillaries, which results in oxygen diffusing from the alveoli into the capillaries. At the same time the carbon dioxide level in the capillaries is high and low in the lungs. So carbon dioxide also diffuses, but in the opposite direction! (carbon dioxide leaves the capillaries and goes into the alveoli) When a person exhales the lungs decrease in size as the air rushes out. Quick over view, breathe in: Oxygen from the alveoli diffuses (enters) into the capillaries Carbon dioxide from the capillaries diffuses (enters) into the alveoli to be exhaled out. (note: water vapor is also exhaled out with the carbon dioxide, that is what you see on a cold winter day when you exhale) or CO2 (carbon dioxide) + H2O (water) vapor out O2 (oxygen) in

Why are the alveoli and bronchi separated in the lungs?
The bronchi are the tubes that actually carry the air to the lungs, they have a different function than the alveoli which function in the process for gas exchange.
