What else can I help you with?
Why do arteries have thicker walls then veins?
Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.
What is the blood pressure when blood leaves the small arteries and enters the capillaries?
The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
How would relaxing the smooth muscles in arteries affect blood pressure?
Blood pressure would decrease
Do veins carry blood at the same pressure as arteries?
No, veins carry blood at a lower pressure than arteries. Blood in arteries is propelled by heart contractions. Venous blood is propelled only by body movement and gravity.
Does pressure drop when blood moves from arteries to veins?
Yes. Blood always flows from a higher pressure to a lower pressure, so as the blood moves from the arteries through the capillaries and into the veins pressure drops considerably.
What is the lowest pressure exerted by blood in your arteries is your- blood pressure?
The lowest pressure exerted by blood in your arteries is your diastolic blood pressure.
Where is blood pressure is the greatest?
in the arteries
Blood pressure is higher in veins than arteries?
No, pressure is higher in the arteries.
How does the body establish a pressure gradient for fluid flow?
A pressure gradient exists in the arteries because the heart actively pumps the blood; additionally, the elasticity of the larger arteries helps force the blood along. There is a lower pressure gradient within the veins that is generated by the muscles squeezing the blood along back to the heart (assisted by valves within the veins).
Why do arteries have thicker walls then veins?
Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.
What blood vessel carries blood at high pressure and why?
Arteries carry blood at high pressure, simply because they are linked directly to the heart and lungs.
In an orbiting space station would the blood pressure in major arteries in the leg ever be greater than the blood pressure in major arteries in neck?
yes the blood pressure in major arteries in the leg is greater than the blood pressure in arteries in neck during orbiting in an orbiting space station.
What generates blood pressure?
Blood pressure is generated by the force exerted by the heart pumping blood into the arteries and the resistance encountered by the blood flow in the arteries. The systolic pressure is the pressure when the heart contracts and pushes blood out, while the diastolic pressure is the pressure when the heart relaxes and refills with blood.
Do Arteries carry blood under high or low?
Arteries carry blood under high pressure. Blood is pumped by the heart into the arteries, which deliver oxygenated blood to tissues throughout the body. The thick, muscular walls of arteries help withstand the pressure of blood being pumped from the heart.
What is the blood pressure when blood leaves the small arteries and enters the capillaries?
The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
What is the pressure when the blood leaves the small arteries and enters the Capillaries?
The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
How would relaxing the smooth muscles in arteries affect blood pressure?
Blood pressure would decrease
