In an experiment to determine the figure of merit of a galvanometer by half deflection method, a student constructed the following circuit. He applied a resistance of in . When is closed and is open, the deflection observed in the galvanometer is 20 div. When is also closed and a resistance of is removed in , the deflection becomes 13 div. The resistance of galvanometer is nearly:
Liquid substances in the animal or human body are known as body fluids. The human body consists of about 60-67% body fluids. The chief components of the human body fluids are blood and lymph. Blood comprises a matrix called plasma with blood corpuscles floating in it. The blood cells are white blood cells, red blood cells, and platelets. Lymph consists of lymph cells.

The main components of blood involve;
A colorless fluid present in the interstitial tissues is lymph. It circulates all over the lymphatic system. It can be described as blood without the RBCs. The exchange of hormones, nutrients, and gases occurs via this fluid. It contains lymphocytes that play a major function in the immune responses of the body.
The movement of blood across the vessels of the body that carries nutrients and gases along with it and removes waste from the different parts of the body is circulation.
There are two types of circulatory systems:
