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.
What moves into the capillaries from alveoli?
probably oxygen
What moves into the capillaries into the alveoli?
probably oxygen
Which substance moves from the alveoli to the blood?
With each inhalation, air fills a large portion of the millions of alveoli. In a process called diffusion (pronounced: dih-fyoo-zhun), oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels, pronounced: kah-puh-ler-eez) that line the alveolar walls. Once in the bloodstream, oxygen gets picked up by a molecule called hemoglobin (pronounced: hee-muh-glo-bun) in the red blood cells. This oxygen-rich blood then flows back to the heart, which pumps it through the arteries to oxygen-hungry tissues throughout the body.
How do alveolar and capillaries work together to provide the muscles with oxygen?
as it moves through blood vessels capillaries in the alveoli walls, your blood takes oxygen from the alveoli and gives off carbon dioxide to the alveoli
Which gas moves from the blood into the alveoli?

This oxygen-rich blood then flows back to the heart, which pumps it through the arteries to oxygen-hungry tissues throughout the body.
Where does blood get new oxygen?
In the lungs. The blood is pumped from the right side of the heart to the lungs. Air moves into the trachea, the bronchi and finally to the alveoli. From the alveoli oxygen diffuses into the microcapilaries (small blood vessels) of the lungs.
How are gasses exchanged in the alveoli?
Oxygen moves into the blood because the partial pressure of oxygen is higher in air and lower in blood. Carbon dioxide moves out of the blood because the particle pressure of carbon dioxide is higher in blood and lower in air.
Why does oxygen moves into lungs?
Inside the red blood cells, the iron has a great affinity for oxygen. It moves by passive diffusion from the alveoli in the lungs into the bloodstream where it binds to the iron groups in the haemoglobin in the red blood cells.
What is it called when oxygen moves from the lungs to the bloodstream?
diffusion - the natural movement of particles from high to low density. oxygen dissolves in a film of liquid water lining the alveoli (tiny air sacs in the lungs) and the wall of the alveoli and wall of the capillary (each 1 cell thick) into the blood in the capillary. the oxygen is moving from the high concentration of oxygen in the lung to the low concentration of oxygen in the blood. this low concentration is maintained in the blood since it continuously flows away and is replaced by oxygen poor blood. the high concentration of oxygen in the lungs is of course maintained by breathing in fresh air.
When the oxygen goes into the bloodstream it goes into arteries veins or capillaries?
Oxygen moves into the lungs to the alveoli in the lungs into capillaries into pulmonary veins to the heart then to arteries that go through the rest of the body.
Where does oxygen move from the respiratory system to circulatory system?
By diffusion across q capillary wall
