Low blood pressure is normally the result of severe bleeding. The issue here is not so much the low blood pressure as it is the lack of blood delivering oxygen to the cells.
High blood pressure, on the other hand, can cause the walls of arteries to rupture. If the wall of an artery gets too weak, it can balloon up and pop. If this happens in a major artery (like in the aortic valve, causing an aortic aneurism), it can very quickly cause death by rapidly decreasing blood pressure inside the circulatory system
What else can I help you with?
What type of bleeding is easiest to control?
Venous blood flow is easiest to control. Arterial blood flow is hardest to control because it is under pressure from the heart.
Why is it important that the veins contain valves?
to maintain blood flow and pressure
Blood vessels that play more important role in the regulation of blood flow to the tissues and blood pressure are the?
the arteries
How do precapillary sphincters help regulate blood pressure and body temperature?
the Precapillary Sphincters control blood pressure and body temperature by regulating the flow of blood to the capillary bed.
What is the difference between vasodilate and vasoconstrict?
Vasodilation is the widening of blood vessels, resulting in increased blood flow and decreased blood pressure. Vasoconstriction is the narrowing of blood vessels, leading to decreased blood flow and increased blood pressure. Both play important roles in regulating blood flow and maintaining homeostasis in the body.
Why doesn't the human body change the driving pressure to control blood flow?
The human body primarily regulates blood flow through changes in the diameter of blood vessels (vasodilation and vasoconstriction) rather than altering driving pressure. This allows for precise control of blood flow to specific tissues without significantly impacting overall blood pressure. Additionally, maintaining a stable driving pressure is crucial for ensuring adequate perfusion to vital organs and preventing damage to blood vessels. By adjusting vessel resistance, the body can efficiently direct blood flow where it is needed most.
How to stop wrist blood flow?
=We cannot stop blood flow, we can only control it!==To control blood flowing from an injury to the wrist - put some gloves on, wrap a bandage around the wrist to covor the injury, apply pressure to the injury site, elevate the injury higher than the heart and apply pressure to the brachial pressure point.=
How the muscles in an artery regulate blood flow?
There are no muscles in arteries. Arterioles have muscles which can close them, but which has no normal flow control. (Used is stress/shock conditions only) Capillaries have a muscle which can stop all flow through it - it responds to oxygen pressure and is the ultimate control of blood flow.

How does the relationship between blood flow, pressure, and resistance impact overall cardiovascular health?
The relationship between blood flow, pressure, and resistance is crucial for cardiovascular health. When blood flow is restricted due to increased resistance in the blood vessels, it can lead to high blood pressure and strain on the heart. This can increase the risk of heart disease, stroke, and other cardiovascular problems. Maintaining a balance between blood flow, pressure, and resistance is important for overall cardiovascular health.
Intrinsic control of blood flow refers to the?
control of blood flow by metabolic products of the tissues
Do the aortic and pulmonary valves control the flow of the blood into the heart?
No, semilunar valves control the flow of blood out of the heart.
