Rectangular coordinate system - The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the one (usual..

The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the one (usually drawn horizontally) is called the x-axi..

Systemic is the most widespread circulatory pathway. It accounts for supply of oxygenated blood to all the parts of the body and collection of deoxygenated blood from the tissues. The left ventricle of the heart opens into a major artery called the aorta. The aorta branches just abov..

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..
