Explain relationship between a cell, a tissue, organ and organ system.

$\Huge{\boxed{\purple{\mathcal{ANSWER}}}}$

A cell is a single body. Organisms who are made up of single cell are called as unicellular organisms. Whereas, organisms which are made up of more than 1 cell are called as multicellular organisms.

In unicellular organisms, the whole work like respiration, locomotion, etc., is done by just one cell.

But in multicellular organisms, many cells join together and form a tissue which would perform a specific function.

Thus, many similar kinds of tissues combine together to form a organ, whivh would perform a specific function. For example : - Our stomach is used to digest the food.

Many organs join together to form a digestive system. For example : - Digestive system.

There are lot of organs in digestive system, but the main are as follows : -

1. Salivary glands

2. Pharynx

3. Esophagus

4. Stomach

5. Small intestine

6. Large intestine

7. Rectum

Many such organ system join together and form an organism such as human beings.

A diagram of cell, tissue, organ and organ system is referred in the attachments.

2. Stomach tissues

3. Stomach

4. Digestive system
