The list of normal reference ranges for various blood electrolytes is extensive. So if you have type A blood, it's either A positive or A negative. Blood circulates through our body and delivers essential substances like oxygen and nutrients to the bodys cells. With the exception of pulmonary and umbilical arteries and their corresponding veins, arteries carry oxygenated blood away from the heart and deliver it to the body via arterioles and capillaries, where the oxygen is consumed; afterwards, venules and veins carry deoxygenated blood back to the heart. Blood is prevented from clotting in the blood vessels by their smoothness, and the finely tuned balance of clotting factors.

In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Arterial blood carries oxygen from inhaled air to all of the cells of the body, and venous blood carries carbon dioxide, a waste product of metabolism by cells, to the lungs to be exhaled. Compared with vertebrate blood, however, that of the invertebrates has relatively few cells. [17] Blood pH, partial pressure of oxygen (pO2), partial pressure of carbon dioxide (pCO2), and bicarbonate (HCO3) are carefully regulated by a number of homeostatic mechanisms, which exert their influence principally through the respiratory system and the urinary system to control the acidbase balance and respiration, which is called compensation. There are other organs and systems in our bodies that help regulate blood cells. Automated cell counters perform this test. There are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. Problems with blood composition, the pumping action of the heart, or narrowing of blood vessels can have many consequences including hypoxia (lack of oxygen) of the tissues supplied. 2.
