Interrelationship Between Cell, Tissue and Organs in Human Body

Interrelationship Between Cell, Tissue and Organs in Human Body

Cell

The cell is the simplest and smallest unit, capable of carrying all the life activities. Each cell is capable of performing the basic functions of life such as respiration, reproduction, excretion, growth etc. All these life processes are performed by their single cell. So, the cell is the structural and functional unit of life. A cell can be defined as the protoplasm surrounded by the cell membrane, which works as structural and functional unit of life.


Tissue

The tissue is defined as a group or layer of similarly specialized cells which together performs certain special functions. Cells combine together inside the body to form a tissue, each of which has a specialized function e.g. blood, muscles bone etc. Blood is a kind of tissue which also consists of many cells and provides transportation inside our bodies and helps in movement.


Organs

Organs are made up of group or layer of tissues. Organs have various functions according of its structure. Some of the organs do multiple functions. For example: Heart pumps the blood and regulates the blood in all body. Kidney purifies water and also regulates water in surrounding.

System

Various organs forms system. There are 9 systems in the human body. Every system has their unique functions. Table of system with its organ and functions in animals is below:

S.N System Organs Main functions
1 Skeletal system
  1. Bones
  2. Joints
 To protect internal organs and give rigidity to a body.
2 Muscular system
  1. Muscles
  2. Tendons and ligaments
 To control the movements of the body.

  11. Appendix
 To extract nutrients from food and excrete waste products from the body.
4 Respiratory system
  1. Nose
  2. Larynx and pharynx
  3. Trachea and Bronchi
  4. Lungs
 To add oxygen to the blood and remove carbon dioxide from the blood.
5 Circulatory system
  1. Heart
  2. Blood vessels
 To pump blood and circulates it throughout the body.
6 Excretory system
  1. Kidneys
  2. Ureters
  3. Bladder
  4. Urethra
 To filterwaste products from the blood.
7 Nervous system
  1. Brain
  2. Spinal cord
  3. Nerves
 To directs intentional and many automatic actions of the body and enable thinking, self-awareness, and emotions.
8 Reproductive system
  1. Ovaries
  2. Testes
 To enable reproduction.
9 Glandular system
  1. Pituitary gland
  2. Thyroid gland
  3. Parathyroid gland
  4. Adrenal gland
  5. Pancreas
  6. gonads
 To produce chemical messenger and circulate them through the blood, which direct the activities to the different organ.

Relation between cell, tissue, organ and system in animals

Various types of tissues are grouped together to form an organ which carries out one or more specific activities. In a multicellular organism, several interrelated organs arranged into an organ system. For example: The respiratory system includes organs such as the nose, pharynx, larynx, trachea, lungs etc. They are composed of different types of cells. Likewise, the digestive system includes organs such as mouth, salivary glands, stomach, intestine, liver, gallbladder, pancreas etc. The main function of the digestive system is to take in food and carry out its digestion, absorption, and egestion.
