Living Things and Life Process
Organization And Structure Of The Body
All living things are made up of one or more cells. For this reason, cells are known as the structural units or the building blocks of life.
Tissues : A group of cells that performs a special job together is known as a tissue. Blood, bone, muscle and skin are some of the tissues in your body. For example, muscle tissues are a group of cells, specialized to contract and expand for the movement of body parts.
Organ : Tissues combine to form an organ. Each organ performs some important function of the body. For example, the heart is an organ that pumps blood to various parts of the body. The eye is an organ that enables you to see. Lungs, kidneys and liver are some other organs which perform important roles in your body.
Organ system : Groups of organs work together to carry out various life activities in our body. For example the food pipe, stomach, small intestine, large intestine and some other organs together help you to digest the food you eat. Such a group of organs is called an organ system. The group of organs that carry out digestion of food collectively form the digestive system. Some other systems in your body are: circulatory, respiratory, nervous, urinary (or excretory), reproductive, muscular and skeletal system .
The main systems in the human body and their functions are given:
| ORGAN SYSTEM | MAIN ORGANS | MAIN FUNCTIONS |
| Skeletal system | bones | gives support to the body; protects internal organs; allow movement |
| Muscular system | muscles | movement of body parts |
| Circulatory system | heart, blood, blood vessels | transport nutrients and oxygen to all parts of body; transports waste |
| Nervous system | brain, spinal cord, nerves | controls all functions of the body |
| Respiratory system | nose, wind pipe, lungs | takes in oxygen and remove carbon dioxide gas |
| Digestive system | teeth, food pipe, stomach, small intestine, large intestine | Digest and absorb nutrients necessary for growth and maintenance of the body |
| Excretory system | kidneys,ureters,bladder, urethra, skin | removes waste from the body |
| Reproductive system | female : ovaries, oviducts, uterus, penis | produces offsprings |
All these systems together form your body. They all work to keep you alive. Thus, the human body, and the bodies of all multiceliular living organisms, are organized as follows:
In bigger bodies there are a large number of cells whereas in some organisms there is only one cell. The cell can be seen ____________________ | |||
