2025年2月12日 · Blood vessels move blood through your body. They help deliver oxygen to organs and tissues and remove waste. Blood vessels include veins, arteries and capillaries.

2021年9月23日 · Continuous capillaries are tiny blood vessels that deliver blood, nutrients and oxygen to your cells. Two types, continuous fenestrated capillaries and continuous nonfenestrated capillaries, have different purposes. Many genetic and nongenetic conditions may affect your continuous capillaries.

2022年10月11日 · The great vessels of the heart include your aorta, pulmonary trunk, pulmonary veins and vena cava (superior and inferior). They connect directly to your heart and play a vital role in your circulatory system. These blood vessels send blood between your heart and lungs (pulmonary circuit) and between your heart and body (systemic circuit).

2021年9月21日 · Your heart pumps blood to the body through a network of arteries and veins (blood vessels). Your circulatory system can also be defined as your cardiovascular system. Cardio means heart, and vascular refers to blood vessels.

2022年6月19日 · Veins are blood vessels located throughout your body that collect oxygen-poor blood and return it to your heart. Veins are part of your circulatory system. They work together with other blood vessels and your heart to keep your blood moving. Veins hold …

2024年9月4日 · Your cardiovascular system functions with the help of blood vessels. Some blood vessels (veins) return blood to your heart, while others (arteries) carry blood away from your heart. Your blood vessels work with your heart and lungs to continuously move blood through your body. Here’s how:

2022年7月6日 · Vascular malformations, or abnormal blood vessel changes, include venous malformations and arteriovenous malformations (AVMs). They may look like birthmarks that develop during infancy. AVMs can form in the brain or spine, causing life-threatening problems.

2022年4月30日 · Arteries, part of your circulatory (cardiovascular) system, are the blood vessels that bring oxygen-rich blood from your heart to all of your body’s cells. They play a crucial role in distributing oxygen, nutrients and hormones throughout your body.

Arterioles, small blood vessels that carry blood away from your heart, are connectors between your arteries and capillaries. They control your blood pressure and blood flow throughout your body, using their muscles to change their diameter.

The aorta is a large, cane-shaped vessel that delivers oxygen-rich blood to your body. It starts in the lower-left part of the heart and passes through the chest and abdomen. Along the way, blood vessels branch off the aorta, extending to organs and supporting tissue.
