Describe histological structure ? artery, vein & copillary
Answers
Answer:
Histology, also known as microscopic anatomy or microanatomy,is the branch of biology which studies the microscopic anatomy of biological tissues.
Capillaries consist of a single layer of epithelial cells, the endothelium tunic (tunica intima). Veins and arteries both have two further tunics that surround the endothelium: the middle, tunica media is composed of smooth muscle, while the outer tunica externa is connective tissue (collagen and elastic fibers).
Answer:
Post capillary blood flows into venules and then into progressively larger veins. Compared to arteries, veins have larger diameters and thinner walls. ... The intima and adventitia are similar in structure and function to arteries but the media is much thinner due to significantly less smooth muscle and elastic tissue.
