CONNECTIVE TISSUE 
 
? In biology, unit of life is called as a cell whereas a tissue is a 
cellular assembly which is intermediate between cells and a 
complete organ. Hence a tissue is a group of similar cells from 
the same origin which together carry out a specific function. 
Further grouping of these tissues forms an Organ. 
 
? The human body is made up of 4 types of tissues: muscular 
tissue, epithelial tissue, connective tissue and nervous tissue. 
 
? The cementing material in our body which helps to bind the 
body together and connect all the organs and parts of the body 
is called as connective tissue.   
 
? The cells that make up this tissue are present in a gel-like 
substance called medium or matrix which forms the main 
bulk of the connective tissue.   
 
? The tissue that connects two bones is called a ligament and 
the one which connects muscles to the bones is called as 
tendon. Both of these are a type of dense connective tissue. 
 
? The skin is connected to our muscles with a type of connective 
tissue which is loose and hence this tissue gets its name as an 
areolar or loose connective tissue.

? The bone cells are present in a medium which has calcium 
and phosphorus due to which its appearance is strong and 
hard. Hence bone is a type of skeletal connective tissue. 
 
? The special type of connective tissue which is filled with the fat 
globules is called adipose tissue. 
 
? The blood flows through your entire body and acts as 
transporter of oxygen hence blood is a fluid connective tissue.
