The theory is credited to Schwann and Schleiden. The three postulates of the theory are:

1. All living species comprises of one or more cells.

According to the cell theory, the structure that contains cells is blood

Blood is certainly one of the major connective tissue in the human body. It regarded as a connective mainly because is made up of a non-living fluid whereby cells are suspended.

<h2>Further Explanation</h2>

The plasma is the blood matrix that surrounds the cells and makes up approximately 55% of the blood in the human body.

However, the three types of living cells include

Red blood cells
White blood cells
Platelets

Red blood cells are considered to be the most abundant cells in the human body because of their various functions. They also don’t possess a nucleus. The red blood cells mainly move oxygen and collect carbon dioxide through hemoglobin.

White blood cells are of different types and they are primarily part of the immune system. They help the human body to fight against infection. They spread throughout the body to move to an area where there is an infection in the human body.

The main types of white blood cells include

Basophils
Lymphocytes
Monocytes
Neutrophils
Eosinophils

Platelets form platelet plug which helps the blood to clot. A blood clots forms in the body to repair any damage to the blood vessels.
