From the lungs.
In the lungs of animals, humans included, there is an interchange of oxygen for carbon dioxide. So we inhale oxygen(air) and exhale carbon dioxide.
blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
The red blood cells carry the oxygen in blood.
the blood absorb oxygen in the lungs(cappilaries)
Because your cells need oxygen. Blood has Hemoglobins inside it, which carry oxygen.
Oxygen enters the blood in the alveoli of the lungs
yes. suppy is a word.
part of the tooth contains a rich suppy of nerves and blood vessels
The right and left ventricles of the heart contract, or pump blood, at the same time. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the body.
blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
Cut off the air suppy or cut off the blood flow to the brain.
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
maybe because there isn't enough nutrients in the blood suppy to the egg
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 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.
