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.

∙ 9y agoIn most vertebrates oxygen enters the bloodstream via diffusion at the alveoli of the lungs. This diffusion (a passive thing) is accomplished because oxygen concentration in the lungs is much higher than that of the blood, even than that of oxygenated blood.
Other animals (including many vertebrates) oxygenate via other organs like the skin or gills.
Oxygen dissolves in the liquid lining of the alveoli and then diffuses down a concentration gradient through the walls of the alveoli and capillaries into the plasma and into the red blood cells.

∙ 15y agoIt is pumped around the body, through arteries to the organs and through veins to all the muscles, fat and cell tissue. It is then absorbed by the cells and used in respiration to make energy so we can move and repair cells.. Without oxygen the cells die.
Respiration = Glucose + Oxygen = Carbon dioxide + energy +water

∙ 12y agoAlveoli (air sacs) are very thin walled to reduce the distance that oxygen in the alveoli or carbon dioxide in the blood has to diffuse. They are also very richly vascularized with capillaries so that 70% of the alveoli surface can be used for gas exchange.

What happens after oxygen from air enters the lungs?
after the oxygen from the air enters the lungs,the oxygen gets sent to the heart and then travels through the arteries with the blood.
How can you the oxygen you bring into your body get into the circulatory system?
The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.
When oxygen is being carried back to blood cells?
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
How does the oxygen you inhale get to all of your blood cells?
It enters the bloodstream through the capillaries surrounding the alveoli in the lungs. Oxygen is then transported by the blood to all of the body cells by a protein in the red blood cells called hemoglobin that binds oxygen with a capacity of 1.34 mL O2 per gram of hemoglobin.
How does oxygen get from your lungs and into the blood?
You breathe the oxygen into your lungs. The oxygen then dissolves into the water lining which is called the alveoli. Finally, the oxygen will cling to the red blood cells as they pass through the alveolar capillaries and now the oxygen is in the blood.
When Oxygen-rich blood from the lungs enters the heart at what structure?
The alveoli of the lungs are surrounded by capillaries. As the blood travels through the capillaries, the red blood cells become oxygenated and give up their load of CO2
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.
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 are some of like a cell membrane to the human?
The lungs are similar to a cell membrane in the sense that oxygen enters the alveoli similarly to how it enters cells.
What sequence correctly shows the path of carbon dioxide during respiration?
External respiration is the exchange of oxygen and carbon dioxide between the lungs, body and the outside environment; the breathing process known as inhalation and exhalation. Upon inhalation, air enters the body and is warmed, moistened, and filtered as it passes to the alveoli of the lungs. Oxygen diffuses from the alveoli to the bloodstream, then into the red blood cells. Simultaneously, carbon dioxide in the blood is diffused from the blood to the alveoli, and exhalation expels the carbon dioxide from the alveoli.
How do red red blood cells pick up oxygen from the alveoli?
red
What leaves the body cells and enters the blood then leaves the blood cells and enters the lungs?
NUTRIENTS AND OXYGEN also water, minerals, and vitamins
