Describe the structure and function of blood and the body fluids - an essay about different components that make up blood.

Blood plasma is the fluid part of communication melodic phrase that contains nutrients, glucose, proteins, minerals, enzymes, waste products, antibodies, curdling proteins and hormones. Its role is get offing the substances somewhat the body. Plasma contains 90% water and besides 10 the solutes. Erythrocytes (also called ruby- flushed parentage cells) are biconcave disks, containing hemoglobin that transports group O. They transport the oxygen to cells all over the body. The surface land to volume dimension is very large on the erythrocytes so oxygen thaw diffuse very quickly into the cell. They lack organelles meaning that in that respect is more room for hemoglobin. They are small and digest a bun in the oven a flexible membrane which allows them to fit through minute capillaries and transport oxygen extremely close to cells. Leucocytes (also called white extraction cells) have a c record, are much larger than red blood cells and are spherical or irregular in sh ape. in that respect are two main types of leucocytes called granulocytes (they have granular cytoplasm and lobed nuclei) and agranulocytes (the cytoplasm appears smooth and the nucleus is rounded or horseshoe in shape). Agranulocytes populate of monocytes (phagocytic against emergeside(prenominal) cells) and lymphocytes which produce antibodies.

Granulocytes consist of neutrophils (phagocytic and contain lysosomes), eosinophils (phagocytic against allergens) and basophils which makes heparin to prevent unessential blood clots and serotonin to allow phagocytes to leave the blood and enter the site of infection. T he assorted cells are shown below: Oxygen! combines with protohemeoglobin in red blood cells to form oxyhaemoglobin. Haemoglobin is a protein and is made up of 4 polypeptide chains, each with a haem assemblage. Each haem group can pick up 1 molecule of O2. The protein, cosmos fairly small, could pass out of the blood during ultrafiltration in the kidneys so, to insure that it is not lost, it is found deep down red blood cells. The relationship...
