Question
Raju has recently joined the gym. The very first day, while doing exercise, he felt increased rate of respiration, heartbeat, sweating, etc. He got worried as he experienced the sudden changes in his body. He discussed it with his brother who is a biology student. His brother smiled and explained him that these are the normal activities of the organs/ organ systems that occur during exercise for the maintenance of normal physiology of the human body.
  1. Name the processes that are necessary for maintaining normal physiology of the human body.
  2. Define coordination and integration.
  3. Explain the functions of various organs of the by body that are coordinated and integrated during exercise.
  4. What values did Raju's brother possess?

Answer

  1. Coordination and integration of body organs by neural system. Which regulate normal physiology of human body.
  2. Coordination is the process through which two or more organs interact and complement the functions of one another. On the other hand, integration is a process, which makes two or more organs to work as a functional unit in harmony.
  3. When we do exercise, we observe significant increase in the rate of respiration, heartbeat, bloodflow, sweating, etc., to meet enhanced needs of nutrients and energy for increased activities of lungs, hearts, muscles and many other body organs. When we stop exercising, we witness that the increased activities of lungs, heart, nerves, kidneys, muscles, etc., gradually return to normal. Thus, during exercise, functions of various organs of the body are coordinated and integrated.
  4. He has a good knowledge of biology. He has the ability to apply his learning to the practical life.
