Explanation:
There are seven types of connective tissues found in the body of people. These are:
- Areolar Connective Tissue
- Adipose Tissue
- Dense Irregular Tissue
- Dense Regular Tissue
- Cartilages
- Bones
- Blood
Answer:
The cells of connective tissue are loosely spaced and embedded in an intercellular matrix.
They are specialised to connect various body organs.
For example:
Blood (plasma), bones, Cartilage. ligaments and tendons etc.
Plasma:
The fluid (liquid) matrix of blood is called plasma.
Plasma is a yellowish liquid like material.
Plasma contains three types of blood cells suspended in it. These are:
(i) RBC - Red blood cells
(ii) WBC - White blood Cells
(iii) Platelets
Bones:
It is also a connective tissue that forms the framework that supports the body.
It is a strong and non-flexible tissue.
Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds.
Ligaments:
Two bones are connected to each other by a connective tissue called the ligament.
This tissue is flexible or elastic in nature.
Tendons:
Bones are connected to muscles by another type of connective tissue named as Tendons.
Tendons are fibrous tissue with great strength but limited flexibility.
Cartilage:
Cartilage is another type of connective tissue which has widely spaced cells.
The solid matrix of this tissue is composed of proteins and sugars.
Cartilage smoothens bone surfaces at joints and is also present in the nose, ear, trachea and larynx.
Cartilage of ear can be folded.
Areolar tissue:
They are found in the skin and muscles, around the blood vessels, nerves, etc.
Function of areolar tissue:
It fills the space inside the organs, supports internal organs and helps in repair of tissues.
Adipose tissue:
It is found between the internal organs and below the skin.
Function of adipose tissue:
It stores fats.
It act as an insulator.
Muscular tissues
Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body.
Main function of muscular tissues is to provide movement to the body.
Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
