What are the main factors that contribute to total peripheral resistance?
Total peripheral resistance is mainly influenced by the diameter of the blood vessels, vessel length, blood viscosity, and the compliance of the vessel walls. Vasoconstriction and vasodilation also play a significant role in regulating total peripheral resistance. Additionally, factors such as arterial blood pressure and neural and hormonal control can impact total peripheral resistance.
Factors that affect vascular resistance?
Vascular resistance is influenced by factors such as vessel radius, vessel length, blood viscosity, and vessel compliance. Changes in these factors can impact the resistance to blood flow in the vasculature, affecting blood pressure and overall circulatory function.
What is the medical term meaning expansion of a blood vessel?
Dilation of a blood vessel is the term for physiologic widening of the vessel. Abnormal widening of the blood vessel through a weakening of the wall is known as aneurysm.Dilation of a blood vessel means widening of the vessel.
What is the function of the ventral blood vessel of a worm?
Blood vessel on the bottom of a worm Blood vessel on the bottom of a worm
What is the effector for blood vessel constriction?
Damage to the blood vessel.
Is the left atrium a blood vessel?
Yes it is a Blood Vessel
What blood vessel carry blood vessel?
The pulmonary artery, because it's the only vessel that oxygenates blood to the lungs.
Which of the following is NOT an important source of resistance to blood flow?
An important source of resistance to blood flow is not low blood viscosity, as low viscosity would actually decrease resistance. The important sources of resistance to blood flow are vessel diameter, vessel length, and blood viscosity.
From what blood vessel does the blood that flows through the grafted blood vessel come?
Aorta
If you rupture a blood vessel can you die?
Yes. It depends on the blood vessel and where it is, but yes a rupture to a blood vessel can kill you. A blood vessel is more likely to "pop" or rupture if it has an aneurysm, which is a local weakness where the blood vessel has stretched from the pressure of the blood. This is more likely to result in death if it is in a large blood vessel or in a critical location, such as the aorta or a vessel in the brain.
Why is the aorta the thickest blood vessel?
Because it has to face the Total Peripheral resistance that is created by the arterioles, and overcome that resistance to pump blood.
Is a blood vessel carrying blood away from the heart an afferent or efferent blood vessel?
efferent
