A countless number of cells make up the human body, all of which vary in shapes and sizes. A cell is defined as the basic structure or unit of living organisms. The different cell types are suited for carrying out specific roles. For instance, the skeletal system is made up of cells which are entirely distinct from those of the digestive system. These are important structures which play a significant role in maintaining the various functions of the body. The following are the main types of cells found in the body
These cells are very crucial in the body. They are cells which play a significant role in transporting oxygen and food to the various parts of the body. They are used in fighting infections. There are three categories of red blood cells: white blood cells, red blood cells, and the platelets. Platelets are used in blood clotting process which is helpful in stopping the loss of blood due to broken or damaged blood vessels.
The red blood cells are found in abundance in the plasma. They are used in transporting oxygen to the various systems in the body. Also, these are the cells which determine someone’s blood group. The white blood cells are helpful in defending the body. They play an essential role in destroying the pathogens thus boosting the immunity of the body.
The skin is the largest organ in the body. It is composed of different layers which include dermis (connective tissue), epidermis (epithelia tissue) and the subcutaneous layer. The skin’s top layer consists of epithelial cells which are closely packed together. The main functions of the skin include preventing dehydration, protecting your body from damage, storage of fats, production of vitamins and hormones as well as protecting the body against germs.
These are also referred to as the neuron cells. These cells are found in the nervous system. The nervous system is responsible for sending signals or impulses to the different parts of your body including the brain and spinal cord. These cells are composed of two major parts: the cell body and nerve processes. The cell body is the part which houses the cytoplasm, nucleus, and the neuron’s organelle. On the other hand, the processes are used in transmitting and conducting signals.
These cells are found in abundance in the cardiovascular and lymphatic system. These are cells which form an internal layer of all the blood vessels in your body. You can find this layer in the skin, lung, lymphatic, brain, and heart cells. Also, these cells are used in the creation of new blood vessels. They have other functions which include the control of the movement of gases, fluid, and macromolecules as well regulating blood pressure.
