In this article we will discuss about:- 1. Introduction to Capillary Circulation 2. Methods of Studying Capillary Circulation 3. Peculiarities 4. Control 5. Interchange. Introduction to Capillary Circulation: The average length of a capillary is 0.5 -1 mm, average diameter, 8 µ or often less than a red cell, average velocity of flow, 0.5 -1 mm per second. Capillaries are [...]
This article will help you to differentiate among artery, vein and capillary. Difference # Artery: 1. Carry blood away from heart. 2. Outer coat is thin middle coat is thick. 3. Lumen is small. 4. Pure oxygenated blood is passed except pulmonary artery. 5. Semilunar valves are absent. 6. Press of blood is high. 7. Blood flow is rapid through [...]
Blood circulates around the body through different blood vessels like Arteries, Veins and Capillaries. Type # 1. Arteries: Arteries carry oxygenated blood away from the heart. Only pulmonary artery is an exception which carries deoxygenated blood. These arteries are divided into smaller branches which are known as arterioles. The walls of the arteries are thick, strong and elastic Blood passes [...]
