(a) What is the lining of blood vessels made up of? (b) What is the lining of small intestine made up of? (e) What is the lining of kidney tubules made up of (d) Where are the epithelial cells with cilia found? 2 Draw different types of epithelial tissue.
Answers
Answer:
(a) Endothelial Cells Line All Blood Vessels
The wall is lined by an exceedingly thin single sheet of endothelial cells, the endothelium, separated from the surrounding outer layers by a basal lamina.
(b) The mucosa is a mucous membrane. It is the innermost lining of the small intestine. It is made up of a: layer of epithelial cells (called the epithelium). (e) Lining of kidney tubules is made up of cuboidal epithelium. It consists of a single layer of cube-like (cuboidal) cells with large, spherical nuclei located in the centre. In the kidney tubules, the cells help in the absorption and transportation of filtered substances
(d) Ciliated epithelia are found in the airways, the uterus and Fallopian tubes, the efferent ducts of the testes, and the ventricular system of the brain.
