Mechanism of Auto-Regulation of Blood Flow (With Diagram)

There are many theories which try to explain the mechanism of auto-regulation of blood flow. They are: 1. Myogenic theory 2. Tissue metabolite theory 3. Tissue fluid pressure theory 4. Renin-angiotensin theory, etc. (this theory is applicable only in kidneys) 1. Myogenic Theory (Fig. 3.53) According to This Theory: i. When there is an increase in pressure, initially there will [...]

Blood Flow: Regulation and Factors (With Diagram)

In this article we will discuss about:- 1. Regulation of Blood Flow 2. Coronary Blood Flow 3. Factors 4. Auto-Regulation. Regulation of Blood Flow: 1. Increased carbon dioxide tension (increased pCO2) is the most important factor. CO2 is a power full vasodilator of the cerebral blood vessels. Increasing the CO2 content of the inspired air (3-5%) almost doubles the blood [...]
