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 [...]
In this article we will discuss about:- 1. Anatomical Considerations of Cerebral Circulation 2. Normal Values of Cerebral Circulation 3. Regulation 4. Factors. Anatomical Considerations of Cerebral Circulation: Blood enters the cranium through four vessels, two internal carotid and two vertebral arteries. The last two combine to form the basilar artery which divides into two posterior cerebral arteries. Each internal [...]
