AOS 1 O2 - Chapter 6.1

Suggest three blood vessels in the body.

• Oxygenated blood

• Arteries

• Veins

• Capillaries

• Deoxygenated blood

Look at the diagram. Suggest two characteristics of an Artery.

• Thick muscular wall needed to pump oxygenated blood away from the heart.

• Thin wall carrying blood at low pressure

• Wider Lumen

• Narrow Lumen

State the role of the arteries in the body.

• Transport oxygenated blood from the lungs to the heart

• Transport oxygenated blood from the heart to the body at high pressure

• allow food and oxygen to diffuse to cells while diffusing waste products from the cells

Look at the diagram. Suggest two characteristics of Veins.

• Thick muscular wall needed to pump oxygenated blood away from the heart.

State the role of the veins in the body.

• Transport oxygenated blood from the lungs to the heart

• Transport oxygenated blood from the heart to the body

• allow food and oxygen to diffuse to cells while diffusing waste products from the cells

• Transport deoxygenated blood to the heart at low pressure

State the role of the capillaries in the body.

• Transport oxygenated blood from the lungs to the heart
