Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen -rich liquid (such as a perfluorocarbon ), rather than breathing air, by selecting a liquid that can hold a large amount of oxygen and is capable of CO 2 gas exchange. [ 1]
Blood flow is also affected by the smoothness of the vessels, resulting in either turbulent (chaotic) or laminar (smooth) flow. Smoothness is reduced by the buildup of fatty deposits on the arterial walls. The Reynolds number (denoted NR or Re) is a relationship that helps determine the behavior of a fluid in a tube, in this case blood in the ...
Hemorheology, also spelled haemorheology ( haemo from Greek ‘αἷμα, haima ' blood '; and rheology, from Greek ῥέω rhéō, ' flow ' and -λoγία, -logia 'study of'), or blood rheology, is the study of flow properties of blood and its elements of plasma and cells. Proper tissue perfusion can occur only when blood's rheological ...
Serum (blood) Preparation of serum cups for a lipids panel designed to test cholesterol levels in a patient's blood. Serum ( / ˈsɪərəm /) is the fluid and solvent component of blood which does not play a role in clotting. [ 1] It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors ...
Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [ 2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [ 3]
The extracellular fluid compartment is further subdivided into the interstitial fluid and the intravascular fluid compartments. Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism. [ 1] In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is ...
Hypoxemia refers to insufficient oxygen in the blood. Thus any cause that influences the rate or volume of air entering the lungs ( ventilation) or any cause that influences the transfer of air from the lungs to the blood may cause hypoxemia. As well as these respiratory causes, cardiovascular causes such as shunts may also result in hypoxemia.
The volume of body fluid, blood glucose, oxygen, and carbon dioxide levels are also tightly homeostatically maintained. The volume of extracellular fluid in a young adult male of 70 kg (154 lbs) is 20% of body weight – about fourteen liters. Eleven liters are interstitial fluid and the remaining three liters are plasma. [7]
