The muscular layer of a blood vessel is the?
The tunica media is the middle layer of the wall of a blood vessel. It is made up of smooth muscle cells and sheets of elastic tissue that help regulate blood flow in the body by causing the blood vessel to narrow or widen.
Widening of the blood vessels as occurs during exercise is termed?
This is called vasodilation. This is easy enough to remember: "vaso" means "blood vessel"; "dilation" means "to widen".
What is the name of procedure that cardiologists ues to widen or reopen narrowed blood vessels in the heart?
The procedure that cardiologists use to widen or reopen narrowed blood vessels in the heart is called angioplasty. During this minimally invasive procedure, a catheter with a balloon at its tip is inserted into the affected artery and inflated to expand the vessel. Often, a stent is also placed to help keep the artery open. This procedure is commonly performed to treat coronary artery disease.
Angioplasty can unblock these?
Angioplasty can unblock narrowed or obstructed blood vessels, particularly the coronary arteries that supply blood to the heart. This minimally invasive procedure involves inserting a balloon into the affected artery and inflating it to widen the vessel, often accompanied by the placement of a stent to keep the artery open. Angioplasty is commonly used to treat conditions like coronary artery disease.
Does the sympathetic nervous system cause vasodilation?
Yes, the sympathetic nervous system can cause vasodilation through the release of certain neurotransmitters that relax the smooth muscles in blood vessel walls, allowing them to widen and increase blood flow.
When your blood vessels widen more is able to get to the large muscle groups?

How do vasodilators work to widen blood vessels and improve blood flow?
Vasodilators work by relaxing the muscles in the walls of blood vessels, causing them to widen. This widening allows for increased blood flow, which can help improve circulation and reduce blood pressure.
What is angioplasties?
An angioplasty is a surgical technique practiced in order to widen an obstructed blood vessel, such as an artery obturated by atheroma. It is practiced by using a ballon catheter to squeeze the atheroma to allow a more natural blood flow through the vessel.
What procedure involves insertion of a device to hold open a vessel and is usually performed after vascular surgery?
The procedure you're referring to is known as angioplasty, often accompanied by the placement of a stent. During angioplasty, a catheter with a balloon is inserted into a narrowed or blocked blood vessel, which is then inflated to widen the vessel. A stent, a small mesh tube, is usually placed to keep the vessel open and maintain proper blood flow, particularly after vascular surgery. This procedure is commonly used to treat conditions like coronary artery disease.
Is marijuana a vasodilator?
Yes. Vasodilators widen the blood vessels in the body, so when you inhale marijuana your pupils widen, which makes marijuana a vasodilator.
What is the purpose of an angioplasm?
Angioplasty is a medical procedure used to widen narrowed or blocked blood vessels, typically in the arteries. It helps improve blood flow to the heart muscle in cases of coronary artery disease or to other parts of the body affected by peripheral artery disease.
How does the body increase the blood vessel radius?
The body increases the blood vessel radius primarily through a process called vasodilation, where the smooth muscle cells in the vessel walls relax. This relaxation is often triggered by factors such as increased carbon dioxide levels, decreased oxygen levels, the release of certain signaling molecules like nitric oxide, and the effects of hormones. As the smooth muscles relax, the blood vessels widen, allowing for increased blood flow to tissues that require more oxygen and nutrients. This process helps regulate blood pressure and improve circulation during physical activity or in response to various physiological needs.
