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.
Your heart pumps your blood throwout the body and it is released from the blood into organs, skin, mussels
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
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).
If the blood cell is red you can tell that it has oxygen
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 blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
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.
no you have oxygen high blood.
oxygen is the answer
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.
