In system theory‚ an open system is a system which continuously interacts with its environment or surroundings. The interaction can take the form of information‚ energy‚ or material transfers into or out of the system boundary‚ depending on the discipline which defines the concept.

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

Lymph Nodes Definition: Lymph nodes: Lymph nodes are small encapsulated organs located along the pathway of lymphatic vessels. They vary from about 1 mm to 1 to 2 cm in diameter and are widely distributed throughout the body‚ with large concentrations occurring in the areas of convergence of lymph vessels. They serve as filters through which lymph percolates on its way to the blood. Antigen-activated lymphocytes differentiate and proliferate by cloning in the lymph nodes. They are packed

Renal system The renal system consists of two kidneys‚ two ureters which come out of the kindeys and a single bladder which collects the urine before it goes into the urethra. It also involves the sphincter muscle which is located just below the bladder and its purpose is to control the flow of urine. The kidneys have renal veins which take the blood from the kidneys into the main vein in the body which is known as the vena cava‚ they also have short renal arteries which come out of the main vein
