Q.1 What do you mean by coordination? Explain its mechanism with examples.
Answer:
Coordination Definition
The coordination is developed when body works as one unit, in which its different organs and systems cooperate and work in harmony with each other.
Explanation
The tissues and organs in the bodies of multicellular organisms do not work independent of each other. They work together performing their many tasks as the needs of the whole body. This means that these activities are coordinated. The process is called coordination. Coordination also enables the organism to respond to happenings in the world around it.
Example No. 1
One familiar example of coordination is the way in which muscles work together during movement. When a boy runs to catch a ball, he uses hundred of muscles to move his arms, legs and back. His nervous system uses information from his sense organs and coordinates these muscles. Due to this coordination, the muscles contract in the correct sequence, power, and length of time. But that is not all. Such activities involve many other kinds of coordination. For example, breathing and heartbeat rates are increased, blood pressure is adjusted, and extra heat is removed fast from the body:
Example No. 2
When we are writing something, our hands and fingers work in collaboration with our muscles, eyes, thoughts etc. and then very intricate movements result.
