H&n - Arteries

Front 1

What is the Vascular System?

Back 1

• The heart and net work of vessels that carry blood throughout the body.

• Consists of an arterial blood supply, a capillary network, and venous drainage.

Front 2

What are Arteries

Back 2

• Vessels that arise from the heart and carry blood away from it.

• Branch into smaller vessels.

Front 3

What are arterioles?

Back 3

Smaller branches of arteries

Front 4

What are capillaries?

Back 4

• A network of tiny branches of vessels that are smaller than arterioles and arteries, veins or venules.

• Can be arterial, venous, or lymphatic.

Front 5

What are veins?

Back 5

• Vessels that travel and carry blood to the heart.

• Veins in the head and neck mostly do not have valves. Veins through the rest of the body do have valves.

• Formed by smaller branches uniting to become larger veins.

• superficial veins are found immediately deep to the skin.
• Deeper veins usually accompany larger arteries in a more protected location with tissue.

Front 6

What are Venules?

Back 6

• Smaller veins which drain the capillaries of the tissue area before uniting to become larger veins.

Front 7

What is an anastomosis?

Back 7

• Connecting channel(s) among vessels by which vesels communicate with eachother.

Front 8

What are Venous Sinuses?

Back 8

• A blood-filled space between two layers of tissue.

• All venous networks are cnnected by anastomoses.
