Physical properties of
blood
Definition of blood Blood DefinitionBlood is a liquid texture, forms of connective tissue is happening inside the body within blood vessels (veins and arteries and capillaries) and consists of a liquid (plasma Plasma) swim blood cells Blood Corpuscles.Physical properties of bloodColor:Red color of blood and the presence of hemoglobin which gives blood on this color, red color varies in arteries than in veins is bright red in the arteries due to the presence of oxygen and dark red in the veins due to the presence of carbon dioxide.Temperature:It is fixed in the body, with some differences which from one member to another as needed for this member of the heat in order to do its main function. For example, the temperature of the liver equal (40-41) degree, either brain The degree temperature equal to less than 36 degrees Celsius.The overall rate of body temperature ranges between 36.8-37.8 degrees Celsius.Blood density:It relies on the presence of substances dissolved in the plasma, such as red blood cells, protein and value for men ranging from (1.057-1.067) g / cm 3.And women ranging between (1.051-1.061) g / cm 3.Blood viscosity:It is a friction force blood walls of the arteries and veins which mainly depend on the proteins found in plasma, especially Alvebrnugen and is important in maintaining blood pressure, a men's 4.7 and women 4.3.Osmosis:And this pressure results from the presence of crystals and minerals in the plasma, due importance to maintain the equivalent of salts and water inside and outside the cell (in the arteries and microvascular).For example, the presence of salts in abundance in the blood causes the withdrawal of water from the cells and this leads to dehydration, but the lack of salt water that causes entry into cells and this is known as water poisoning.
Pressure Alkoloido Asmosze (colloidal):And this pressure results from the presence of proteins in the plasma which is equal to 25 mm Hg and its importance due to:A) to maintain the presence of water within the vascular (blood volume).B) the exchange of nutrients between the blood and cells.A lack of protein in the blood leads to a lack of pressure Alkoloido and Asmosze which keeps water inside the cell and spoke edema Oedema and this pressure is less than the osmotic pressure normally.Density hydrogen concentration in the blood (PH):Usually this density tend to basal (ie blood basic solution) and is equal to this intensity of 7.4 and 7.35 in the arteries veins.The inside the cell is equal to (7-7.2) due to the presence of carbon dioxide.
