Inside the alveoli, oxygen moves across paper-thin walls to the capillaries (tiny blood vessels) and into the blood. It is then picked up by chemicals (haemoglobin) in the red blood cells that carry it around the body. At the same time, waste products from the body, in the form of carbon dioxide, come out of the capillaries back into the alveoli, ready to be breathed out. Freshly oxygenated blood is carried from the lungs to the left side of the heart which pumps blood around the body through the arteries. Once the oxygen has been used up, the blood returns, through the veins, to the right side of the heart. From there it is pumped to the lungs so that the carbon dioxide can be removed and more oxygen taken on board.
Capillaries in your lungs provide oxygen to the haemoglobin molecules of red blood cells.
Yes - oxygen is held in red blood cells (in haemoglobin to be precise). As the blood flows, oxygen is brought all around the body and eventually gets back to the heart and lungs as carbon dioxide (which is what you exhale).
The blood gets oxygen from the lungs during the process of respiration. Oxygen is inhaled into the lungs, where it diffuses into the bloodstream via tiny air sacs called alveoli. This oxygenated blood is then pumped by the heart to the rest of the body.
Combining capacity for oxygen refers to the maximum amount of oxygen that can be bound to hemoglobin in the blood. It is influenced by factors such as the concentration of hemoglobin in the blood and the oxygen saturation level. This measurement is important in assessing the oxygen-carrying capacity of the blood.
First you breath it in and then it goes through you blood stream dropping off oxygen molecules and picking up carbon dioxide all through the body and then it goes to the lungs to get more oxygen and drop off the carbon dioxide so it can be exhaled.
the quality of our blood that rich with oxygen will become low
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
oxygen is the answer
no you have oxygen high blood.
oxygen is transferred to the blood by breathing
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
haemoglobin carries oxygen in the blood
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
Oxygen never fully dissociates from the haemoglobin in the red blood cells. There is a lot more oxygen in arterial blood, but there is still oxygen in veinal blood too.
