How Do Histological Features Affect Blood Pressure?
The elasticity and contractility of the tunica media play a crucial role in maintaining arterial blood pressure. The smooth muscle cells and elastic fibers enable arteries to expand and recoil in response to the pulsatile nature of blood flow from the heart. This elasticity helps to dampen the fluctuations in blood pressure, ensuring a more consistent flow. Any histological changes, such as reduced elasticity due to aging or disease, can affect blood pressure regulation.
