Q

returns deoxygenated blood from the legs to the posterior vena cava

A

iliac vein

21
Q

carries deoxygenated blood returning from the body into the heart

A

vena cava

22
Q

large vein that collects deoxygenated blood from head and arms and returns it to the right atrium of the heart

A

superior / anterior vena cava

23
Q

large vein that collects deoxygenated blood from the abdomen and lower body and returns it to the right atrium of the heart

A

inferior / posterior vena cava

24
Q

takes deoxygenated blood from the head back to the anterior vena cava

A

jugular vein

25
Q

brings deoxygenated blood from the arms back to the anterior vena cava

A

subclavian vein

26
Q

returns deoxygenated blood from the kidneys to the posterior vena cava

A

renal vein

27
Q

returns deoxygenated blood from the liver to the posterior vena cava

A

hepatic vein

28
Q

returns deoxygenated blood from the heart muscle to the right atrium

A

coronary veins

29
Q

artery with the largest diameter in the body, takes oxygenated blood to the upper part of the body, takes oxygenated blood to the lower part of the body, and extends upward from left ventricle of the heart and arches over the heart

A

aorta

30
Q

largest vein, collects deoxygenated blood from head and arms and returns it to the heart, collects deoxygenated blood from abdomen and lower body and returns it to the heart, and when the deoxygenated blood is back in the heart, it is pumped into the lungs

A

vena cava

31
Q

what is the function of the septum?

A

it stops blood from one side of the heart from mixing with the blood on the other side

32
Q

sends oxygen-depleted blood to the lungs to pick up oxygen and unload carbon dioxide

A

pulmonary circuit

33
Q

sends oxygen-rich blood and nutrients to all body cells and removes carbon dioxide and waste

A

systematic circuit

34
Q

high body temperature, when there is excess calcium ions, and when sympathetic fibers secrete norepinephrine at the S/A and A/V nodes

A

increased heart rate

35
Q

lubb

A

occurs during contraction when A/V valves are closing

36
Q

dupp

A

occurs during relaxation when pulmonary valves are closing

37
Q

P wave on ECG

A

depolarization in atrium

38
Q

QRS wave on ECG

A

depolarization in ventricle

39
Q

T wave on ECG

A

repolarization in ventricle

40
Q

average blood pressure

A

120/80

41
Q

top number of blood pressure

A

systolic blood pressure

42
Q

systolic blood pressure

A

max pressure in artery when ventricular is contracting

43
Q

bottom number of blood pressure

A

diastolic blood pressure

44
Q

diastolic blood pressure

A

max pressure in artery when ventricular is relaxing

45
Q

heredity, diet, salt intake, and exercise

A

increase blood pressure

46
Q

cardiac output

A

stroke volume X heart rate

47
Q

follow the path of blood from the heart to the veins

A

heart –> arteries –> arterioles –> capillaries –> venules –> veins

48
Q

follow the path of blood from the right atrium to the body

A
