Four basic tissues in the human body: epithelium: creates a barrier, for the external organs. This is divided into four different groups. This is due to the way the cells are arranged. Simple: simplest way of arranging tissues, single layer. Transitional: when tissues transition between simple and stratified. Simple squamous: flat, squam shaped, are found in the plasma, usually bound in blood (cid:448)essels, bo(cid:449)(cid:373)a(cid:374)"s capsule a(cid:374)d etc. Simple cuboidal epithelium: as tall as they are wide, nucleus is located in the centre. This found in plants and ducts of glands, thyroid gland, and ovary surface. Simple columnar epithelium: these are taller, and nucleus is found at the bottom. These are also found in stomach, intestine, bronchi, kidney tubules, uterus.
