Blood tissie where it is present and its functions
Answers
Answer:
Blood Tissue: Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers. Blood tissues are found inside the blood vessels (arteries, arterioles, capillaries, venules and veins - see the systemic circulation for further details about the path the blood follows and the names of specific blood vessels) and also within the chambers of the heart.
The Functions of blood tissues
1) Transports
dissolved gases (e.g. oxygen, carbon dioxide)
Waste products of metabolism (e.g. water, urea)
Hormones
Enzymes
Nutrients (e.g. glucose, amino acids, micro-nutrients incl. vitamins & minerals, fatty acids, glycerol)
2) Maintains Body Temperature
3) Controls PH. The pH of blood must remain in the range 6.8 to 7.4, otherwise it begins to damage cells.
4) Removes toxins from the body. The kidneys filter all of the blood in the body (approx. 8 pints), 36 times every 24 hours. Toxins removed from the blood by the kidneys leave the body in the urine. (Toxins also leave the body in the form of sweat.)
5) Regulation of Body Fluid Electrolytes
6) Excess salt is removed from the body in urine, which may contain around 10g salt per day (such as in the cases of people on western diets containing more salt than the body requires).
