What is the network of blood vessels?

What is the network of blood vessels?

What is the network of blood vessels?

The blood vessels — a network of interconnecting arteries, arterioles, capillaries, venules, and veins — provide the pathway in which blood travels. Arteries are the passageways through which the blood is delivered, the largest of which is the aorta.

What vessel provides blood to the heart?

Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.

What is the heart and vein system called?

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

What is another name for the heart and circulatory system?

cardiovascular system
cardiovascular system: The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body’s tissues.

What are the two main types of blood vessels called?

Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.

What are the blood vessels that carry blood back to the heart?

For this reason, capillaries are known as exchange vessels. Groups of capillaries within a tissue reunite to form small veins called venules. Venules collect blood from capillaries and drain into veins. Veins are the blood vessels that carry blood back to the heart.

How are blood vessels in the circulatory system support circulation?

Vein. Veins are vessels of the circulatory system that support circulation by conveying blood to the heart. Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body.

How are the atria and ventricles connected to the heart?

The atria are both supplied by large blood vessels that bring blood to the heart (see below for more details). Atria have special valves that open into the ventricles. The ventricles also have valves but, in this case, they open into blood vessels.

How are capillaries related to blood vessels in the heart?

Groups of capillaries within a tissue reunite to form small veins called venules. Venules collect blood from capillaries and drain into veins. Veins are the blood vessels that carry blood back to the heart. They may contain valves which stop blood flowing away from the heart. How do the heart and blood vessels work?

Where are the vessels that carry blood to the heart called?

Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

What happens to the collateral vessels in the heart?

When the coronary arteries narrow to the point that blood flow to the heart muscle is limited ( coronary artery disease ), a network of tiny blood vessels in the heart that aren’t usually open (called collateral vessels) may enlarge and become active.

Vein. Veins are vessels of the circulatory system that support circulation by conveying blood to the heart. Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body.

Where does the heart get its blood from?

Coronary Arteries. The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet.
