sometimes ill be sitting or standing and all of a sudden i lose circulation in my left index finger now its going to the index and the thumb and its always on the left side what should i do?
Cardio Pulmonary Circulation
Red blood cells do not have a nucleus in order for them to be able to carry more oxygen. The only thing they do is transport oxygen, therefore they do not need a nucleus. They do not lose any ability because their only purpose is oxygen transport.
as it loses blood it loses what it has to pulse so you don't have a pulse that is much stronger than the you had
The heart is two side-by-side pumps, each serving a separate blood circuit: - The blood vessels that carry blood to and from the lungs form the pulmonary circuit, which serves gas exchange. - The blood vessels that carry the functional blood supply to and from all body tissues constitute the systematic circuit. Pulmonary circuit - the right side of the heart is the pulmonary circuit pump. Blood returning from the body is relatively oxygen-poor and carbon dioxide-rich. It enters the right atrium and passes into the right ventricle, which pumps it to the lungs via the pulmonary trunk. In the lungs, the blood unloads carbon dioxide and picks up oxygen. The fresh oxygenated blood is carried by the pulmonary veins back to the left side of the heart (left atrium). NOTICE how unique this circulation is. Typically, we think of veins as vessels that carry blood that is relatively oxygen-poor to the heart and arteries as transporters of oxygen-rich blood from the heart to the rest of the body. Exactly the opposite condition exists in the pulmonary circuit. Systematic circuit - the left side of the heart is the systematic circuit pump. Freshly oxygenated blood leaving the lungs is returned to the left atrium and passes into the left ventricle which pumps it into the aorta. From there the blood is transported via smaller systemic arteries to the body tissues, where gases and nutrients are exchanged across the capillary walls. Then the blood once again loaded with carbon dioxide and depleted of oxygen, returns through the systemic veins to the right side of the heart, where it enters the right atrium through the superior and inferior venae cavae.

Blood is always useful. You cannot live without it. Blood is useful in the emergency room when somone loses too much of their own blood.
a child who loses 1 pint of blood is in extreme danger.
Not everyone who loses that much blood dies.
Vibration white finger is a work injury in that one's hand or fingers become white, numb, and one loses finger mobility. It is caused by the fingers and hands vibrating too much as with using a jackhammer.
It loses oxygen!
If an adult loses 40% or more of their total blood level, if not treated as soon as possible it will be fatal.
