Noooooo'''Tissues''' form part of an [[Organ (anatomy)|organ]]. Tissues are groups of [[cells]] that work together to do a job in the body. They are a group of cells having the same origin, structure. Non. and [[function]]. The cells look the same or almost the same. The work the cells do is also the same or almost the same. |

Tissue is different from [[Organ (anatomy)|organ]]. Organs are made up of more than one kind of tissue. The [[heart]] is an organ. It is made up of different tissues. It has [[muscle]] tissue. It has [[connective tissue]] like the [[endocardium]]. The endocardium is the thin layer of tissue that surrounds the heart. The heart has [[ |
|||
valve]]s that make sure the blood goes the right way through the heart. So the heart is an organ made from several tissues. |
|||
The study of the structure of tissues under a [[microscope]] is called [[histology]]. |
