16
Q

Aortic valve and pulmonary valve

A

Control blood flow out of the ventricles

17
Q

Systemic circulation

A

Carries oxygenated blood from left ventricles through the arteries, to the capillaries in the tissues of the body

Deoxygenated blood returns from tissue capillaries through a system of veins to the right atrium of the heart

18
Q

Blood pressure

A

Amount of force the heart has to use to pump blood around the body

19
Q

Cardiac output

A

Volume of blood ejected per min from the left ventricle to the aorta

20
Q

Peripheral resistance

A

Resistance of arteries to blood flow: increases when arteries constrict and when decreases when they dilate

21
Q

Stroke volume

A

Amount of blood ejected by left ventricle during each heartbeat

22
Q

Heart rate

A

Number of heartbeat per min

23
Q

Acute Haemolytic Reaction

A

Triggered by host antibodies destroy donor red blood cells

24
Q

Blood group A

A

A antigens on red blood cells + B anti bodies in the plasma

25
Q

Blood group B

A

Had B antigens + A antibodies in the plasma

26
Q

Blood group O

A

Has no antigen and both anti A and anti B bodies in the plasma

27
Q

Blood group AB

A

Both A + B antigens and no antibodies

28
Q

Aorta

A

Contains blood at the highest pressure
