What happens to amount of fresh air entering alveoli when tidal volume declines?
What happens is that the air volume entering the alveoli also decreases. Tidal volume is the quantity of air that enters and leaves the lungs during quiet breathing.
What is the diffences between respiration and breathing?
respiration happens inside the body and breathing happens outside the body
What are the alveoli and what happens in them?
the alveoli is happen the blood
What system allows for the exchange of carbon dioxide and oxygen between the air and the blood?
It happens in the alveoli of the lungs
The two breathing organs where gas exchange occurs in the body?
The alveoli
What is the tissue in the human body for breathing?
There is not really a tissue for breathing at all, more like an organ called the lungs. In the lungs, oxygen goes through the bronchial tubes into the alveoli In the alveoli the oxygen atoms are diffused into the blood stream and transported throughout the body by red blood cells. The same thing happens when you exhale, carbon dioxide is exchanged in the alveoli for oxygen, and the carbon dioxide exits the body, all in a matter of seconds.
Describe what happens in the alveoli sacs?
When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
Is alveoli used in both respiraton and breathing or only in respiration?
Respiration is a technical word for breathing. it means the same thing.
Where does the oxygen pass into the blood in the breathing system?
In the capillaries surrounding the alveoli in the lungs
What happens to carbon dioxide during external respiration?
During external respiration, carbon dioxide is released from the body by diffusing from the blood into the alveoli in the lungs. It is then exhaled out of the body during the process of breathing.
Why is the alveolus important to the breathing system of humans?
Alveoli in the lungs are important because they help with the transportation of oxygen to the blood. They are also called the pulmonary alveoli.
Where in the lung does exchange of O2 and CO2 take place?
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
