Q

How does a double circulation system work?

A

Right side of heart pumps blood to lungs to exchange oxygen and carbon dioxide

Left side of heart pumps blood to the rest of the body

Q

Why is the wall of the left ventricle thicker than the right ventricle?

A

Has to pump blood at higher pressure around the whole body.

Q

What is the purpose of the heart valves?

A

Prevent the back flow of blood

17
Q

What is the role of the coronary arteries?

A

Supply the heart muscle with oxygen and glucose

18
Q

Name the blood vessel labelled B

A

Aorta

19
Q

Name the chamber labelled D

A

Left ventricle

20
Q

Name the structures labelled A

A

Valves

21
Q

Name the blood vessel labelled C

A

Pulmonary vein

22
Q

Blood flowing along the pulmonary artery is going to …?

A

Lungs

23
Q

Name the blood vessel that brings blood from the lungs to the left atrium

A

Pulmonary vein

24
Q

Name the blood vessel that takes blood away from the left ventricle

A

Aorta

25
Q

Name the blood vessel labelled D

A

Pulmonary artery

26
Q

Describe the flow of blood through the right side of the heart

A

Blood enters atrium via the vena cava

Atrium contracts

Blood forced through the heart valve into the ventricle

Ventricle contracts

Blood is forced into the pulmonary artery and sent to the lungs

27
Q

What is the approximate value of a resting heart rate?

A

60-70 beats per minute

28
Q

Where in the heart is the natural pacemaker?

A

Wall of the right atrium

29
Q

How can an abnormal heart rhythm be treated?

A

Artificial pacemaker which send out electrical signals

to correct the hearts rhythm

30
Q

Name the three types of blood vessel

A

Arteries
Capillaries
Veins

31
Q

How are the arteries adapted for their function?

A

Function - carry blood away from the heart

Adaptions
Thick wall to withstand the high pressure
Lots of muscle tissue - to add strength and allow wall to recoil
Lots of elastic tissue - allows artery to stretch and recoil

32
Q

How are veins adapted for their function?

A

Function- carry blood towards the heart

Adaptations
Wide lumen to reduce pressure
Valves to prevent backflow of blood

33
Q

How are capillaries adapted for their function?

A

Function - deliver glucose and oxygen to the tissues, remove carbon dioxide and urea from the cells

Adaptations
Walls one cell thick - short diffusion distance
Permeable walls - substances can get out and into the blood
Narrow lumen - blood moves slowly to give more time for diffusion

34
Q

Name the blood vessel labelled A

A

Vena Cava
