blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
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.
Planting more trees and preserving existing forests is the best way to maintain the world's oxygen supply. Trees absorb carbon dioxide and release oxygen through photosynthesis, helping to balance the oxygen and carbon dioxide levels in the atmosphere. By protecting and expanding forest areas, we can help mitigate the decrease in the world's oxygen supply.
We should first start at the beginning. As you know, you breathe oxygen in when you contract your diaphragm and air fills your lungs. The walls of your lungs are filled with capillaries (tiny blood vessels) that look kind of like feathers. If you were to stretch out the entire surface area of the capillaries in your lungs, it would be about equal to the size of a tennis court! So, in the capillaries flows your de-oxygenated blood. It has been on a complete cycle through your body, and is now low on O2. When the erythrocytes (red blood cells) enter the capillaries, the oxygen gets chemically stuck to them. It attaches to a large protein called hemoglobin, a 4 piece protein with a single iron atom at the center. (this explains why an iron deficiency can lead to anemia, or a low red blood cell count) Each red blood cell contains as many, many hemoglobin molecules. The oxygen is at a HIGH concentration in your lungs, and so flows into the LOW concentration in the blood. As the laws of nature would predict, as the red blood cells move into areas of lower oxygen concentration, the oxygen leaves the hemoglobin and enters its new tissue.
They pollinate plants, and this is necessary to create new plants. The new plants create oxygen, so I would say yes. But, to be fair, they do it indirectly.
If moisture and oxygen combine with steel wool, the new substance produced is iron oxide, commonly known as rust. Rust forms on the surface of the steel wool as a result of the oxidation reaction between iron, oxygen, and water.
The heart pumps your blood (cardio), into your lungs (respitory), to give them oxygen. Then it makes itsway around the body to supply oxygen to where it is needed. Then then new blood, without oxygen, goes on the exact same path.

A section of tissue detached from its blood supply, moved to another part of the body, and reattached by microsurgery to a new blood supply
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
Nerve cells can typically survive without a new blood supply for about 4-6 minutes before irreversible damage occurs due to oxygen and nutrient deprivation. After this time, cell death may occur, leading to permanent neurological impairment.
Yes, the right atrium which receives oxygen poor blood from the body, channels it into the right ventricle which pumps that blood to the lungs to unload its carbon dioxide and pick up a fresh new supply of oxygen. That freshly oxygenated blood from the lungs returns to our left atrium which channels it into the left ventricle which in turn pumps it out to the rest of the body. And the cycle begins anew.
Yes, there is not an infinite supply of blood in your body. It's just the same blood being recycled by your heart. When your blood goes around your body, it's deprived of oxygen, so your heart kind of "freshens" the blood cells when they return to the heart. That's why people sometimes die from loss of blood.
No, red blood cells do not have the ability to repair damaged tissues. Their main function is to transport oxygen from the lungs to the rest of the body and remove carbon dioxide. Tissue repair is typically carried out by other types of cells in the body, such as white blood cells and fibroblasts.
Coronary artery bypass graft is the procedure done to provide the myocardium with a new source of blood supply when a coronary artery is occluded.

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 constant movement of the people helped them increase their food supply because they kept using up all of the food in that one place then they would move and use all of the other places food supply. that way they kept being able to maintain a good food supply
