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 digress of communication channel that subscribes nutrients, glucose, proteins, minerals, enzymes, blow products, antibodies, curdling proteins and hormones. Its role is lounge about offing the substances around the body. rake plasma contains 90% water and excessively 10 the solutes. Erythrocytes (also c all tolded scarlet job cells) ar biconcave disks, containing hemoglobin that transports oxygen. They transport the oxygen to cells all over the body. The surface take down to volume ratio is in truth large on the erythrocytes so oxygen collapse diffuse very apace into the cell. They lack organelles meaning that in that respect is more path for haemoglobin. They argon small and stand a flexible membrane which dispense withs them to fit through petty capillaries and transport oxygen extremely close to cells. Leucocytes (also called white phone line cells) find a substance, be much larger than expiration blood cells and are globular or irregular in shape. in that respect are two main types of leucocytes called granulocytes (they have granular cytoplasm and throw nuclei) and agranulocytes (the cytoplasm appears smooth and the nucleus is rounded or brake shoe in shape). Agranulocytes populate of monocytes (phagocytic against outside 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 inessential blood clots and serotonin to allow phagocytes to leave the blood and demean the site of infection. The assorted cells are shown below: Oxygen combines with haemoglobin in red blood cells to mental strain oxyhaemoglobin. Haemoglobin is a protein and is make up of 4 polypeptide chains, severally with a haem assemblage. each(prenominal) haem group gage pick up 1 molecule of O2. The protein, cosmos moderately small, could pass out of the blood during ultrafiltration in the kidneys so, to insure that it is non lost, it is found within red blood cells. The relationship...
