1 unit blood = 500cc = 8-10 pints

The above answer is partially correct; however, 500cs is one pint not 8-10 pints

1 unit of whole blood is approximately 500cc or ~ 1 pint

Alcohol is processed like a carbohydrate, and is taken in to be oxidized by the cells. Since it is already in liquid form, alcohol is absorbed through the stomach lining into the bloodstream. However, its effects on the body trigger its prompt removal by the kidneys. As much as 5% to 10% of consumed alcohol is excreted without oxidation. Alcohol can block normal metabolism in the liver and pancreas, and excessive or prolonged use can cause severe organ damage.

When an individual has excessive bleeding, their blood is exiting their system faster than blood is being produced and supplied in the body. By supplying saline to the victim, it raises their volume of fluid in their body as well as contributing to keep their blood pressure elevated too in order to help prevent further shock. This is a temporary solution, in order to keep the patient as stable as possible on the way to definitive care such as the hospital.

The are several cell types in blood. One of these types of cells are the Red Blood Cells. The red blood cells perform several functions, including carrying oxygen from the lungs. Doctors routinly measure the number of red blood cells (and other cell types, like white blood cells and platelets) in a small sample of blood taken from a person. This is reported as a concentration commonly referred to as the red blood cell count. Typically men do have a higher concentration of red blood cells than women do. But this is affected by many conditions in both health and disease.

Cotinine is tricky but I will tell you that most people will say that it stays in your sytem for about 2 to 4 days. I will tell you honestly..Try more than 3 months...I quit smoking 3 months ago and have not touched another cigarette or even been around it. I tested positive for cotinine on my last nicotine test. I was a heavy smoker but I even used cleansing products and still failed. Nothing will help you get rid of it but time, exercise, lots of water or juice, and never smoking again...Hope this helps
