In this system the unit of length is foot (F), of mass is the pound (P) and of time is the second (S..

The transport system in animals is called the circulatory system. The materials are transported from one part of the body to another by a mass flow system which is the circulatory system. The animals, particularly the more advanced forms, have a higher metabo..

The condition of the system when its macroscopic properties have definite measurable values, is the state of a system. If any of the macroscopic properties of the system changes such as its temperature, pressure etc., the state of the system is also said to ..

A system, which can exchange energy but not mass with the surroundings is called a closed system. For example, boiling water in a closed steel vessel is an example of a closed system. The energy can be gained or lost (through the steel walls) but not matter. Similarly..

The process of supplying water to crops in the fields by means of canals, reservoirs, wells, river valley systems and river lift systems is known as irrigati..

Lymphatic System - Lymphatic System of a Human The lymphatic system is an accessory circulatory system which transports lymph, a fluid similar to plasma from the intercellular spaces of tissues to the blood. It is a one way route for the movement of interstit..

Root is the descending portion of the axis of the plant. It is not normally green in colour. It is characterised by the absence of nodes and internodes. There are two types of root systems, the tap root system (seen in dicots) and fibrous root system (seen in monocots)..

It is represented by a pair of kidneys, a pair of ureters and a urinary bladder. Kidney contain numerous units called nephrons which filter blood, remove urea and convert it into urine. It is collected in the urinary bladder through ureters (kidney ducts), temporarily stored and then periodically e..
