The blood vessels are the tubes that carry the blood to and from the heart. They could be likened to the "Plumbing pipes" in a house. These blood vessels, through which the blood flows, are called arteries, veins, and capillaries.
The heart acts as a pump to push the blood through the blood vessels. Arteries carry oxygenated blood and nutrients from the heart to the body's tissues, while veins carry the "used" blood from the body tissues back to the heart.
The heart then pumps the used blood to go through the lungs again to pick up more oxygen. When the lungs fill the blood with oxygen again, the heart pumps the oxygenated blood through the arteries back out to the body organs and tissues. This circle of blood from the heart to the lungs and out to the body then back to the heart and lungs and so on, is called "circulation". The heart and blood vessels are called the circulatory system. The tiny blood vessels called capillaries, that reach into the tissue in smaller and smaller branches, are also a part of the circulatory system.
The circulatory system is called the cardiovascular system in medical terminology. "Cardio" means heart and "vascular" means blood vessels.
Since you use the word small, these vessels are called venoules.
The heart help the body by circulating the blood throughout the body .It also ensures that the oxygen flows in all different parts of the body .
Veins - return deoxygenated blood to the heart to be reoxygenated. In contrast to arteries that bring the oxgenated blood from the heart, to the rest of the body for use.
Energy that the muscles use release heat as a by-product, which it then cooled by the dilation of blood vessels and sweating.
The heart is responsible for pumping blood to all parts of the body via a network of blood vessels. It contracts and relaxes to push blood through the circulatory system, ensuring that oxygen and nutrients are delivered to cells throughout the body.
The diagnostic procedure you are referring to is called angiography. It involves the use of contrast material and special imaging techniques to visualize blood vessels and blood flow in various parts of the body, such as the heart, brain, or extremities.
to pump blood
Squid use oxygen from seawater for respiration. The seawater enters the mantle through the opening near the head, and passes over the gills. Oxygen diffuses from the water into the blood, and is transported to the gill (or branchial) hearts by a network of many blood vessels.
Long term alcohol use causes the blood vessels to become more fragile and prone to rupture. Alcoholics have a much higher risk of stroke, aneurysms esophageal varicies and bleeding disorders.
Blood travels around your body via Veins and comes out via Arteries i remember it by veIN
Blood pressure may be reduced with the use of vasodilators, which work by relaxing and enlarging the lumen of blood vessels, leading to decreased resistance and improved blood flow. This can help in lowering blood pressure by reducing the workload on the heart.
Muscle tissue and blood vessels both use fibroblasts, a precursor for the smooth muscle cells that stabilize the blood vessels. One difference is that the muscle tissue requires oxygenated blood in order to function.
