Aim
The aim of this experiment is to identify the morphological features of Erythrocytes, leukocytes and Thrombocytes, to carry out out a differential white cell count and to describe the parameters used to identify different types of anaemias.
Introduction
Blood is a specialised body fluid, which acts as a liquid connective tissue, by being involved around the heart and the blood vessels within the body. The main components of the blood is 55% plasma liquid and 45% Erythrocytes, leukocytes and Thrombocytes. Among others, blood in the body has three main principle functions, transport, regulation and protection. Blood transport involves About 98.5% of the oxygen in arterial blood pressure, The haemoglobin in the blood is the primary transporter of oxygen, where it helps carry blood oxygen to the lungs, Carbon Dioxide is then carried in the blood stream by Erythrocytes and passed to the lungs and the dissolved nutrients from the G-I Tract, such as amino acids and fatty acids are carried through the body by the plasma in the blood cells, the transportation of blood cells, mainly the plasma found in blood, also has a main job to play in the disposal of waste products, for example urea through the kidneys, and helps hormones through the body through the plasma protein albumin which is essential in carrying hormones like fatty acids, this helps the endocrine glands hormones to reach its target cells.
The Regulation of blood in the body is very important as it acts as a pH buffer by maintaining body temperature,the blood dispenses heat around the body through the arteries and blood vessels, blood also helps to keep the cells and tissues of the body from losing their water content, the plasma in the blood is also very important in the regulation of the body as it maintains osmotic pressure. The principle of protection involves haemostasis, in which the clotting occurs to prevent fluid loss, and if an injury to the
