Each of these components carries out different functions to allow for bodily processes to happen i.e. respiration, digestion, and immunisation. This image shows the composition of blood in which erythrocytes, thrombocytes, leucocytes and plasma all form part of the blood. Plasma: Plasma is a pale straw-coloured liquid, in which water forms 90% of the composition of plasma with the other 10% consisting of substances. In turn plasma accounts for 55 % of the composition of blood. Substances present in plasma include CO2, urea, glucose, amino acids, ions, hormones, antibodies, anti toxins and other nutrients. CO2 is produced as a by-product in the process of respiration and dissolves in the blood (plasma) after cells have respired aerobically. This is then transported to the lungs where it is exhaled forming the 4% of exhaled CO2 in exhalation. Urea (a waste product)...
