After oxygen leaves the lungs, it enters the bloodstream through the alveoli in the lungs. It then travels to the heart, which pumps the oxygen-rich blood to various tissues and organs in the body. The oxygen is used by cells in these tissues and organs for energy production through a process called cellular respiration.

What happens to the oxygen level in blood as it moves through the lungs?
As blood moves through the lungs, oxygen is exchanged for carbon dioxide. Oxygen diffuses from the air in the lungs into the blood, increasing the oxygen level in the blood. Conversely, carbon dioxide diffuses from the blood into the air in the lungs, decreasing the carbon dioxide level in the blood.
What is the place where oxygen enters the body and carbon dioxide leaves it?
The lungs are the organs where oxygen enters the body and carbon dioxide leaves it through the process of respiration. Oxygen is taken in when breathing and carbon dioxide is released when exhaling.
Where do oxygen rich blood go after leaving the lungs?
Oxygen-rich blood leaves the lungs through the pulmonary veins and is transported to the left side of the heart. From there, it is pumped out to the rest of the body through the aorta and the systemic circulation to provide oxygen to tissues and organs.
Where does oxygen poor blood go from the heart?
Oxygen-poor blood leaves the heart via the pulmonary artery and is transported to the lungs for oxygenation. Once it picks up oxygen in the lungs, it returns to the heart through the pulmonary vein to be pumped out to the rest of the body.
What is the process that allows oxygen carbon dioxide to transfer?
The process that allows oxygen and carbon dioxide to transfer is called respiration. In the lungs, oxygen is taken in from the air we breathe and is exchanged for carbon dioxide that is then exhaled. This gas exchange occurs in the alveoli, tiny air sacs in the lungs, where oxygen enters the bloodstream and carbon dioxide leaves it.
Why is it different when the composition of the air as it enters the lung compaerd to when it leaves the lung?
The air that enters the lungs is richer in oxygen when it enters the lungs. when it leaves it has more carbon dioxide and less oxygen as the lungs expel carbon dioxde and some unused oxygen.
When you breath in what happens to your lungs?
When you inhale, you breath in oxygen and your lungs get bigger.
Where does blood go AFTER it leaves the pulmonary arteries?
Blood leaves the pulmonary artery and travels into the lungs. In the lungs the blood releases carbon dioxide and picks up oxygen.
Why leaves are the lungs of the earth?
Because they exchange Carbon Dioxide into Oxygen
What leaves the lungs and goes into the blood?
Oxygen leaves the lungs and enters the blood during the process of respiration. When we inhale, oxygen-rich air fills the alveoli in the lungs, where oxygen diffuses across the alveolar walls into the bloodstream. This oxygen binds to hemoglobin in red blood cells and is then transported to tissues throughout the body. Additionally, carbon dioxide, a waste product of metabolism, moves from the blood into the lungs to be exhaled.
Do the lungs remove salt?
No. The lungs are where we exchange carbon dioxide and oxygen. Salt leaves the body through sweat and urine.
Why does air move in the lungs?
We breath because the oxygen/CO2 levels in our lungs are less than that of our surroundings. When you breathe in, your lungs expand and allow more oxygen to flow in. When you exhale, the CO2 levels in your lungs is greater than the your surroundings, so the CO2 leaves and the process repeats itself. This is called negative pressure breathing.
Under quiet conditions what percentage of oxygen is retained by blood returning to the heart when it leaves the lungs?
Approximately 98-99% of the oxygen is retained by the blood returning to the heart when it leaves the lungs under quiet conditions.
What happens to the oxygen levels in the blood as it moves through the lungs?
the oxygen releases carbon dioxide
What happens to each of these gases in the lungs?
Two main gases exchange in the lungs: oxygen and carbon dioxide.
What location in the body is carbon and oxygen exchanged?
This process happens in the lungs.
What kind of blood does lungs have?
Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
