In this article we will discuss about the mechanisms of blood circulation in humans:- 1. Coronary Circulation 2. Cerebral Circulation 3. Microcirculation 4. Pulmonary Circulation 5. Fetal Circulation 6. Splanchnic Circulation 7. Intestinal Circulation. 1. Coronary Circulation: Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium).

In this article we will discuss about:- 1. Characteristics of Pulmonary Circulation 2. Pressures in the Pulmonary System 3. Factors 4. Measurement. Characteristics of Pulmonary Circulation: 1. The entire pulmonary vascular system is a distensible low pressure system. 2. Reservoir: Because of their distensibility, the pulmonary veins act as an important blood reservoir. The volume of blood at any one [...]
