Animal tissue organization is a complex and targeted towards mobility of animals, most of the them are living. Growth is not limited to areas. It required more energy for maintenance and after reaching maturity stage animals do not show further growth.
Further in this article we are going to learn 4 types of animal tissue and their classification and animal tissue flow chart.
Animal epithelial tissues are present on the surface of their body and also present at the inner lining of an organ.
Function of epithelial tissue is to serve as a protective, absorptive, secretory and sensory function.
classification of epithelial tissue
1. squamous epithelial tissue
These tissue are flattened cells with centrally placed nucleus.
It is present at the lining of air sacs (Aleve).
These are also present at the lining of Kidney Tubules and in the lining of blood capillaries.
Function of squamous epithelial tissue is to help in exchange of gasses, absorption and in exchange of materials.
2.cuboidal epithelial tissue
Cuboidal epithelial tissue have cube-like cells which are present at the lining of the celebre and pancreatic duct.
These cells have approximately equal dimensions in height, width, and depth.
Function of cuboidal epithelial tissue is to helps in absorption and secretions.
4. Ciliated Epithelium
It is also known as respiratory epithelium or ciliated columnar epithelium and has Cilia at its free end which are responsible for coordinated, rhythmic movements that help mucus to move, particles, and fluids along the surfaces of the tissue
Ciliated epithelium is found in at the lining of the fallopian tube, trachea and kidney tubules, lungs etc.
Function of ciliated epithelium is to helps in cleaning and transportation.
2. Connective tissue
Connective Tissue is widespread tissue in the human body.
Function of connective tissue is to provide structural support, connecting different tissues and organs, storing energy, and transporting nutrients.
Types of Connective Tissue
1. Areolar Connective Tissue
They are dense connective.
Areolar connective tissue function is to help in maintaining the skeletal framework of our body.
Areolar include Tendons and Ligaments.
1(a). Tendons
Tendons are those connective tissues which connect skeletal muscle to the bones. Tendons and ligaments are examples of connective tissue.
1(B). ligaments
Ligaments are those connective tissues which attach one bone to another and help us in smooth movement of our body.
2. Adipose Tissue
It is a type of loose connective tissue which is mostly located beneath the skin.
Adipose tissue function is to store fats or excess nutrients which are not used immediately.
They also provides warmth to our body.
2(a). Loose connective tissue
They are those which are loosely arranged in a semi fluid ground substance. Loose connective tissue are represented by Adipose.
3. Skeletal
3(A). Bone
Bone is a supporting connective tissue which gives the skeletal framework of our body.
These cells are known as osteocytes.
Bone is composed of calcium and phosphorus compounds.
Bones have hard ground substances and collagen fibers.
It helps in supporting and protecting our various internal organs and other soft tissues.
Two bones are connected with each other through a connective tissue known as ligament, It is an elastic which has considerable strength.
3(b). Cartilage
Cartilage is also a supporting connective tissue which is composed of chondrocytes.
They are flexible in nature and they are mostly present at the bone ends, ears, nose, trachea etc.
4. Fluid connective (Blood)
4(a). Blood
Blood is a fluid connective tissue which helps in transportation of nutrients as well as various gasses through different parts of our body. Blood is composed of two major components plasma and blood cells.
3. Muscular Tissue
They are composed of long excitable cells which helps in contraction and relaxation of the muscles. and can be divided into two basic types :
Voluntary muscles are found in the skeleton like head, limbs, face etc and these are under our direct control, they are striated in texture. These are present in various parts of our body and they have very rich blood supply and these muscles can contract, relax at the will of a person and they have large numbers of nucleus or multinucleated.
Involuntary Muscles: They are not under our direct control and they are present at the wall of body organs like the stomach and intestine and these are uni-nucleated in nature and they do not have any striation.
Types of Muscular tissue
4(a). Cardiac Muscular
They are present at the walls of the hearts. They are striated muscles and mostly Uni-nucleated in nature. Heart muscles are involuntary in nature and they have a rich supply of blood.
4. Nervous Tissue
They are made up of two types of cells i.e. neurons and neuroglial cells.
Neurons are those cells which act as a functional unit of nervous tissue.
They helps in formation of the brain, spinal cord, nerves and sensory cells as well as sense organs.
Neurons help in transmission of messages from one place to another another.
Both neuroglia and neurons lead to the formation of full nervous tissues which helps in transmission of nerve impulses.
Conclusion
Animal tissue is classified into 4 types for the proper functioning of animals. Epithelial is divided into Squamous, Cuboidal and Ciliated which helps in transportation and absorption, Connective tissue is divided into Areolar, Adipose and Skeletal which helps in keeping skeletal framework and smooth movement of body. Further Muscular tissues is responsible for contraction and relaxation of muscles where Voluntary Muscles are under our direct control, Involuntary muscular which are not under our direct control and lastly Nervous tissues which are made up of two types of cells i.e. neurons and neuroglial cells and helps in transferring of messages from one place to another another.
Their organization is complex and targeted towards mobility of animals and most of them are living.

Tissue present in animal only known as animal tissues. They protects inner lying parts of animal
