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

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
brings deoxygenated blood from the arms back to the anterior vena cava
subclavian vein
26
returns deoxygenated blood from the kidneys to the posterior vena cava
renal vein
27
returns deoxygenated blood from the liver to the posterior vena cava
hepatic vein
28
returns deoxygenated blood from the heart muscle to the right atrium
coronary veins
29
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
aorta
30
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
vena cava
31
what is the function of the septum?
it stops blood from one side of the heart from mixing with the blood on the other side
32
sends oxygen-depleted blood to the lungs to pick up oxygen and unload carbon dioxide
pulmonary circuit
33
sends oxygen-rich blood and nutrients to all body cells and removes carbon dioxide and waste
systematic circuit
34
high body temperature, when there is excess calcium ions, and when sympathetic fibers secrete norepinephrine at the S/A and A/V nodes
increased heart rate
35
lubb
occurs during contraction when A/V valves are closing
36
dupp
occurs during relaxation when pulmonary valves are closing
37
P wave on ECG
depolarization in atrium
38
QRS wave on ECG
depolarization in ventricle
39
T wave on ECG
repolarization in ventricle
40
average blood pressure
120/80
41
top number of blood pressure
systolic blood pressure
42
systolic blood pressure
max pressure in artery when ventricular is contracting
43
bottom number of blood pressure
diastolic blood pressure
44
diastolic blood pressure
max pressure in artery when ventricular is relaxing
45
heredity, diet, salt intake, and exercise
increase blood pressure
46
cardiac output
stroke volume X heart rate
47
follow the path of blood from the heart to the veins
heart --> arteries --> arterioles --> capillaries --> venules --> veins
48
follow the path of blood from the right atrium to the body
(the 21 steps)
