What else can I help you with?
What cause blood to flow through blood vessel?
blood pressure produced by the pumping of the heart
What makes the blood flow inside the tubes or blood vessel?
Contractions and relaxation of heart chambers make the blood flow inside the tubes or blood vessel.
What are serious but infrquent complications of atherectomy?
blood vessel holes, blood vessel wall tears, or reduced blood flow to the heart
What affects the flow of blood through the heart?
things that could affect the blood flow through the heart
What is blood flow generated by?
The flow of blood times the resistance of the blood vessels.
How does the body control blood vessel size and blood flow?
The blood vessels are made up of an internal layer of muscle fibers, which are capable of contraction and relaxation. The contraction of the muscles reduces the lumen size of the vessel, making the blood flow faster while relaxation allows more room for blood to flow, thus blood flow rate is reduced.
What makes the blood flow inside the tube or blood vessels?
Contractions and relaxation of heart chambers make the blood flow inside the tubes or blood vessel.
What is the flow of blood through your heart and around your body called?
Circulation of the blood
What factors influences resistance to blood flow in the arteries?
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
What is the affect on blood flow on the radius vessels?
The relationship between blood flow through a vessel and the radius of the vessel can be expressed as BF=1/pi r4 (where pi is equal to 3.14.....). So a change in the radius of a vessel has a large effect on the blood flow through the vessel.
How is sodium balance ECF volume and blood pressure are jointly regulated?
for blood to flow through a vessel or across a heart valve, there must be a force propelling the blood. This force is the difference in blood pressure (i.e., pressure gradient) across the vessel length or across the valve.
What will happen to flow rate if you increase the radius of a blood vessel?
If you increase the radius of a blood vessel, the flow rate of blood through that vessel will increase significantly. This is due to the principles of fluid dynamics, specifically Poiseuille's law, which states that flow rate is proportional to the fourth power of the radius. As the radius increases, resistance to flow decreases, allowing more blood to flow through the vessel with less pressure required. Consequently, a larger radius enhances overall blood circulation in the body.
