Types Of Cells And Tissues

The human body is a complex structure with different types of cells and tissues.

For those who want to know more about it, here is a brief explanation.



One of the most common type of blood cell, and the major means of oxygen delivery to body tissues in a vertebrate organism, is red blood cells which is also known as erythrocytes and is term that is quite discussed among the types of cells and tissues. Even though the basic structure of red blood cells is the same, they are classified into different types based on the molecules, inherited antigenic, attached to them. Types of red cells are based on two systems, Rh blood group system and the ABO blood group systems.


Among the types of cells and tissues, white blood cells, which are also called as leucocytes, are responsible for the immune action and defending our body against diseases. White blood cells are produced from bone marrow. There are five different types of white blood cells namely:

– Neutrophil

– Eosinophil

– Basophil

– Lymphocyte

– Monocyte


Tissue is the term used to mention the organizational structure formed by cells that collectively undertake a specific function in the body. Tissues can also be considered as an intermediate level in between a complete organism and a cell. Similar cells combined together forms a tissue that undertakes a specific functions and several such tissues form an organ.


These types of cells and tissues are a type of fibrous tissues that are made up of separated, non-living material cells and responsible for giving shape to organs and also for holding them in place. The best example of connective tissue are blood and bone tissues that give the structural shape to our body and also keep them in place. The difference between connective and epithelial tissues are that connective tissue has cells scattered in an extracellular matrix unlike epithelial tissues.


This is the type of tissue formed by the muscle cells and is active contractile tissue of the body that is responsible for producing force and causing motion. The motion can be either the locomotion of the entire body, parts or the motion of internal organs of the body.

Muscle tissues are further classified into three types:

– Visceral or smooth muscle tissues

– Skeletal muscle

– Cardiac muscle


Among the types of cells and tissues, nervous tissue is the tissue that is formed by cells that comprises of central nervous system and peripheral nervous systems. The central nervous system contains bran and spinal cord and, cranial nerves and spinal nerves form peripheral nervous system. Nervous tissue is responsible for transmitting messages in the form of neural signals, called as impulse, in the body.


Epithelial tissue is the term used to refer to the types of cells and tissues that acts as a covering for other tissues, organs etc. The epithelial tissue cells are connected via a semi permeable membrane acts as a barrier between the foreign environment and the organ while facilitating selective absorption and secretion that are necessary for the organs. This type of tissue protects the organisms from fluid loss, microorganisms and injury.

Different types of epithelial tissues are:

– Squamous epithelium

– Cuboidal epithelium

– Columnar epithelium

– Glandular epithelium

– Ciliated epithelium
