The Cardiovascualar System

What is the main Artery that transports blood from the left ventricle to the body?

• Vena Cava

• Pulmonary Artery

• Aorta

• Pulmonary Vein

"The amount of blood pumped out of the left ventricle in one contraction"

• Cardiac Output

• Heart Rate

• Stroke Volume

What is the role of the systemic circuit in the double circulatory system?

• –transports blood between the heart and the lungs

• transports blood from the heart to the rest of the body

What are two differences between veins and arteries

• Veins have valves and carry blood away from the heart

• Arteries have valves and carry blood away from the heart

• Veins have valves and carry blood to the heart

• Arteries have valves and carry blood to the heart

What is the role of the capillaries?

• To enable effective gaseous exchange around muscles and organs

• To carry blood away from the heart

• To carry blood to the heart

• To stop the backflow of blood

What does the term vasodilation mean?

• Artery walls decrease in size reducing blood flow

• Artery walls increase in size allowing more blood flow

"The amount of blood pumped out of the left ventricle each minute".

• Stroke Volume

• Cardiac Output

• Heart rate

What is the role of valves in the double circulatory system

• To stop blood entering the heart

• To increase the blood flow

• To transport blood around the body

• To prevent the backflow of blood

A performer has completed a 6 month training programme. Please tick the three long term effects on the heart?

• Increase in Stroke volume

• Increase in Cardiac Output

• Higher resting heart rate

• Cardiac Hypertrophy

Please explain the vascular shunting mechanism

• Process of the redistribution of blood, Increase supply of blood to working muscles (Vasodilation) /Decrease of supply to other organs (Vasoconstriction)

• Process of the redistribution of blood, Increase supply of blood to working muscles (Vasoconstriction) /Decrease of supply to other organs (Vasodilation)

• Process of the redistribution of blood, Decrease supply of blood to working muscles (Vasodilation) /Increase of supply to other organs (Vasoconstriction)

• Process of the redistribution of blood, Decrease supply of blood to working muscles (Vasoconstriction) /Increase of supply to other organs (Vasodilation)
