In this article we will discuss about the anatomy of cutaneous circulation in humans with the help of suitable diagram. Vascular architecture of the skin has the general pattern of the capillary circulation. For the most part, papillae contain capillary blood vessels and nerve endings. The arteries that supply the skin, originate from richly anastomosing irregular plexus (first plexus) of [...]
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 [...]
In this article we will discuss about:- 1. Definition and Effects of Haemorrhage 2. Role of Atrial and Ventricular Receptors and the Sino-Aortic Baroreceptors in Haemorrhage 3. Compensatory Changes. Definition and Effects of Haemorrhage: Escape of blood, from ruptured blood vessels is called haemorrhage. The effects of haemorrhage depend on the amount and rapidity of blood loss, and the efficiency [...]
