Study of the functioning of living organisms or their constituent tissues or cells. An understanding of biochemistry is fundamental to physiology. Physiological processes are dynamic; cells change their function in response to changes in the composition of their local environment, and the organism responds to alterations in both its internal and external environment. Many physiological reactions are aimed at preserving a constant physical and chemical internal environment (homeostasis) Physiology Lab: Determination of blood pressure in human ( how to use the stethoscope and sphygmanometer ). Observation of the effect of the position and exercise on cardiac activity ( blood pressure & pulse rate ). Determination of bleeding time. Determination of clotting time. Estimation of hemoglobin (Hb) concentration in gm/ 100ml of blood. Find out your own blood group. Counting of RBCs by using HEMOCYTOMETER. Counting of WBCs by using HEMOCYTOMETER. Lab Safety Rules: Do NOT bring food or drink into the lab. Chewing gum, applying cosmetics, putting pens or pencils into your mouth Always wear shoes in the lab. Use proper safety protection --- lab coat , goggles, gloves. Keep the laboratory as clean and neat as possible at all times. Put extra books, purses, coats, etc. well away from the work area.
