All About Biological Life Processes

We are surrounded by living things. This entire world is made up of living things. Every living thing goes through a life process.

Living beings carry out various functions to sustain themselves and to live and to continue living. These functions together are called as life processes.

Nutrition, Respiration, Transportation of substances, Excretion, Movement, and Reproduction are the different life processes.

  • Nutrition: Organisms/ living things need food to live and survive. The process of taking the food and utilizing the whole food is called nutrition.
  • Respiration: Respiration is the process of releasing energy from the food. In this process, the oxygen is taken in into the cells and used for releasing energy by burning the food consumed and releasing or eliminating the waste such as carbon dioxide and water.
  • Transportation of substances: The transportation system in the animals and plants are completely different from each other. Transportation is a process where the materials or the substances going inside the body are carried to different parts of the body to release energy and nutrients.
  • Excretion: Excretion is the process of eliminating the waste and toxic substances from the body. The plants, animals and human beings have completely different excretion process. It is very necessary to excrete the waste out of the body

You can learn about the life processes in detail. Life processes of every living being have been explained in the biology textbook class 10 Science Chapter 6.


Another important part of the living beings is control and coordination of the human body. Human brains play an important and major role in the control and coordination of the body.

The human brain is a very complex organ which is comprised mostly of nervous tissues. The brain is covered with a three layered system of membranes known as meninges. The different parts of the human brain are forebrain, Midbrain, and hindbrain.

Human beings have to respond and interact with the external environment. The responses made by the human beings in relation to the external stimuli are controlled and coordinated by a system.

Nervous system: Nervous system plays an important role in the control and coordination of the human body. It comprises of nervous tissues.

Neuron: The nerve cell/neuron is the functional unit in the nervous system. The neuron is responsible for the transmission of nerve impulses.

Types of Neuron: The nervous system in humans is divided into two parts: the central nervous system and the peripheral nervous system.

  • Central Nervous System:s The brain controls all the functions in the human body.
  • Peripheral Nervous system: It consists of the cranial nerves and the spinal nerves.
  • Autonomous Nervous System: It controls all the involuntary actions performed by the human body. For example:

Voluntary and Involuntary Actions:

Voluntary Actions: These are the actions that we do it consciously and in control with the brain. Example: Kicking the ball, lifting object etc.

Involuntary Actions: These are the actions that we perform without the conscious control of the brain. These actions are not under control. Example: breathing, sweating, heart beating etc.

You can learn more about the control and coordination in detail. The information and detailed notes are available in the control and coordination class 10 biology textbook.
