How does elastic recoil of arteries stop blood pressure going to zero and artey collapsing? Thanks

sameeralord said:Do you mean volume of the artery increases and then comes back to normal, so there is always some blood remaining? I'm really not sure please can you give me a straight forward answer. Thanks!

Someone else asked a question that led me to point them to a Wiggers Diagram that they didn't understand. I didn't feel capable of answering their follow-up questions but thought about it a bit.
Depending where blood pressure is measured, for instance, core volume provides a large determinant for BP. I started to analogize static head for a mechanical pump.
Anyway, look at a Wigger Diagram and note that nowhere does it plot precisely zero pressure. Aortic pressure is low but not zero, ventricle pressure is far from zero, as is arterial/aortic pressure.
The elastic recoil of arteries refers to the ability of the arterial walls to stretch and then return to their original shape. This is due to the presence of elastic fibers in the arterial walls, which allow them to expand and contract in response to changes in blood pressure.
The elastic recoil of arteries plays a crucial role in regulating blood pressure. When the heart pumps blood into the arteries, the elastic walls of the arteries stretch to accommodate the increased volume of blood. This stretching helps to reduce the pressure of the blood flow, preventing it from reaching dangerously high levels.
If the elastic recoil of arteries is impaired, it can lead to high blood pressure or hypertension. This is because the arteries are unable to stretch and accommodate the increased blood flow, causing the pressure to rise. Over time, this can lead to damage to the arteries and other organs in the body.
The elastic recoil of arteries is essential in maintaining blood pressure and preventing it from dropping to zero. When the heart relaxes between beats, the elastic recoil of the arteries helps to maintain a continuous flow of blood by pushing the blood forward. This prevents the blood pressure from dropping to zero and ensures that vital organs receive a consistent supply of oxygen and nutrients.
Yes, the elastic recoil of arteries can be improved through regular exercise, a healthy diet, and avoiding risk factors for cardiovascular disease, such as smoking and excess alcohol consumption. These lifestyle changes can help to maintain the elasticity of the arterial walls, thereby improving their ability to regulate blood pressure.
