Identify the incorrect element of the cardio-vascular system

• Lungs

• Blood

• Blood Vessels

How many blood vessel types are there

• 1

• 2

• 3

• 4

Identify the vessel which enables diffusion of oxygen in to the working muscle

• Artery

• Capillary

• Vein

• Alveoli

Arteries carry blood to the heart

• True

• False

The pulmonary artery takes blood away from the heart to the lungs, the blood in this artery is...

• ...oxygenated

• ...deoxygenated

During exercise _______________ blood travels to the working muscles

• Oxygenated

• Deoxygenated

• Red

• Blue

Select the vessel which has a thick muscular wall and small lumen

• Artery

• Vein

• Capillary

• Alveoli

The internal diameter of a blood vessel is called...

• ...the blood passage way

• ...the inside of the vessel

• ...the measurement of a vessel

• ...the lumen

Vascular shunting involves the process of...

• Vaso-constriction which directs blood to resting muscles

• Vaso-dilation thus reducing the lumen diameter

• Vaso-constrction that reduces blood flow to working muscles

• Vaso-dilation which increases the blood flow to working muscles
