2021年7月9日 · Blood vessels circulate blood throughout your body. They help deliver oxygen to vital organs and tissues, and also remove waste products. Blood vessels include veins, arteries and capillaries.

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.

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:

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 · The circulatory system includes the heart and blood vessels. Your heart sends blood to the lungs for oxygen. It pumps oxygen-rich blood to the rest of the body.

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 most of the blood in your body.

2022年2月24日 · 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.
