If I got accurate only I mark your answer as brilliantest answer guys. what is the function of tissue?


Gauravmj: In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues

Tissue are group of cell that perform a common function .

There four basic types of tissues :-

1) EPITHELIAL TISSUE :- It covers all the organs or body surface to protect that body from moisture loss , bacteria , and internal injury . There are two types of Epithelial tissue :-

→ Covering and lining Epithelium :- It covers the outermost layer of the skin and other organs , and the internal surface lining of lymph vessels and digestive tract .

→ Glandular Epithelium :- Secretes hormones or other product such as stomach acid .

2) CONNECTIVE TISSUE :- It performs a variety of functions including support and structure to the body . This tissue has two types :-

→ Loose Connective Tissue :- Holds the structure toge . For example , it holds the outer layer of skin to the underlying muscle tissue . Thus tissue also found in fat layers , lymph nodes , and red bone marrow .

→ Fibrous Connective Tissue :- Holds the body part together . It found in ligaments , tendons , and bone .

3) NERVOUS TISSUE :- It is present in the entire nervous s including brain and spinal cord , responsible for coordinating the activities and movement of the body through its network of nerves . It consists of two kind of nerves cells :

→ Neurons are the basic structural unit of the nervous system . Each cells consists of cell body , dendrites , and axon .

→ Neuroglia provide support functions for the neurons .These cells does not multiply and , are formed during birth and last till death .

4) MUSCLE TISSUE :- It makes muscle of the body . This tissues is made up of muscle fibres that contain many myofibrils , which are the parts of the fibres that actually contract . This tissue comes in three types :-

→ Skeletal Muscle is attached to the bones and cause movements of the body .

→ Cardiac Muscle is found in the heart .

→ Smooth Muscle lines the walls of blood vessels and certain organ such as the digestive and urogenital tracts .
