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.
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
Blood receives a new supply of oxygen in the lungs through the process of respiration. When we breathe in, oxygen from the air enters the lungs and diffuses into the blood in the capillaries of the lungs, where it binds to hemoglobin in red blood cells.
blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
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.
