University review We study microstructures at three structural levels:cells,tissues,organs Cells -is the smallest structure and functional unit of living organisms. Tissues-groups of cells and intercellular substances make up the body tissues. Organs-several different kinds of tissue are further organised to form organs System-several organs with related functions together form systems

Anhui Medical University Organs Several different kinds of tissues are organised in particular ways to form organs. From the structure view,there are two kinds of organs in human body 1)cavity organs 2)parenchyma organs

1)Cavity organs The wall of cavity organs can be divided into three or four layers. The wall of blood vessels is made up of three layers: ①tunica intima ②tunica media ③tunica adventitia
