Document Summary
Blood: made up of fluid and cells, fluid - plasma, water 90% Lipoproteins: proteins which attach to lipids to aid their transport in the blood, 4 types, chylomicrons (cm, high density lipoproteins (hdl, low density lipoproteins (ldl, very low density lipoproteins (vldl) Haemoglobin and erythrocytes: a protein found within the erythrocytes, erythrocytes. Important for transport of oxygen and carbon dioxide: flat biconcave discs, contain several hundred million (109) haemoglobin molecules per cell, have no nucleus or organelles no room in cell. Carbon dioxide transport: co2 is transported either as, bicarbonate (important to remember, this is the primary form of transport within the blood. Important because bicarbonate ions is a major buffer for the body: attached to haemoglobin, binds to the globin not the haem. In addition to o2 and co2 blood also transports: bicarbonate ions (hco3, h, nitric oxide (no, helps to stabilize blood pressure by dilating blood vessels, hydrogen sulphide (h2s, stimulates vasodilation.
