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.
Yes you body is always making new cells by methods of mitosis or meiosis. The dividing of cells. Each cell (excluding cancer and stem cells) have a hayflick limit which states the amount of times that the cell can divide (: Hope i helped
Red blood cells are responsible for transporting oxygen around the body, but they do not protect the body from disease. The immune system, which is made up of white blood cells and other components, is the primary defense against pathogens and diseases.
Round about 21 days is the average span of a blood cell
After donating blood, red blood cells are replaced by bone marrow, but usually takes a month to be fully replaced, but it can also take longer depending on how frequently the donor donates blood.
After a tooth extraction, a blood clot forms in the empty socket to help with healing and protect the area. The blood clot serves as a scaffold for new tissue growth. Over time, the blood clot will break down and be replaced by new tissue as the extraction site heals.
Illnesses where the body has trouble making new blood cells
According to a healthy lifestyle book that I just read recently, it is in theory (not proven yet) that they last for approximentally 4 months. Your body is always making new blood cells, so there is no need to worry if you have a healthy & active lifestyle.

Yes Your body regenerates new blood cells very quickly, yet some quickly die. If the body did not regenerate new blood cells you would run out of blood, and then yourself die.
For the most part. Arteries are better described as saying they always carry blood away from the heart. Every artery in the human body carries oxygenated blood, except the pulmonary artery. The pulmonary artery carries blood from the heart to the lungs in order to "pick up" a new supply of O2 which it then carries back to the heart and to the rest of the body.
yes, there is always blood in vampire movies, most of them are based around blood.
Because blood cells don't last forever. Even if you haven't got any injuries thay still get used up "internally", and if your body aren't making new ones well enough you can still need a transfusion.
Red blood cells carry oxygen throughout the circulatory system, which allows the tissue cells to produce energy through aerobic respiration. The red blood cells pick up oxygen in the lungs and carry it through the arteries in the body to the tissues. When they reach the smallest vessels, capillaries, oxygen is easily dropped off and the cells make their way back to the heart and then into the lungs. They will continue this cycle for about 100-120 days. Because the body is always making new blood, it is safe, under most circumstances, to donate blood.
