Circulatory System

angio-

vessel

arteriolo-

arteriole-small

a/telo-

incomplete or without/end

auricolo-

ear shaped heart part

conio-

dust

lympho-

watery

plasmo-

blood fluid, cells float

anguino-

blood

pericardium

a double membrane fibrous sac that encloses the heart, surrounding the myocardmiun and is the progom of the bodys great blood vessels

visceral pericardium

inner serous layer, aka epicardium

pericardium

outer fibrous layer. also called parietal

myocardium

is the middle heart layer, consisting of the heart muscle

coronary artery

blood vessels that supply blood directly to heart muscle

heart attacks are usually referred to as coronary thrombosis myocardial infarction

blood returns to the heart from (2)

the neck and the arms through the superior vena cava

and

from the bottom part of the body through the inferior vena cava

to the right atrium

blood flows from the right atrium to

down through the right tricuspid (atrioventricular) valve into the right ventricle

right side of the heart pumps blood to the

lungs, which is why its considered the pulmonary side of the heart

the AV node generated impulses to

the lower chambers, causing systole/contraction

right ventricle pumps blood through the

pulmonary valve to the lungs for oxygenation

oxygenated blood returns from the lungs

under pressure to the left atrium down to the left ventricle through the mitral valve

when the left ventricle contracts

it pumps blood out of the heart through the aortic calve and up out the aortic arch

3 layers of arteries and veins

tunica intima

tunica media

tunica externa

lymphatic system

network of capillaries, valves, ducts, nodes, and organs that help protect and maintain the internal fluid environment of the body by producing, filtering, and conveying lymph and producing blood cells

what does the lymphatic system transport

fats, proteins, and other substances to the blood system and restores fluid that filters out of the blood capillaries into interstitial spaced

lymph collected is drained into

the blood through the thoracic and lymphatic duct

body muscle contractions pump the lymph through the system

bone marrow becomes what type of cell

hematopoietic stem cells

hematopoietic stem cells can become what cells

myeloid progenitor cells or lymphoid progenitor cell

lymphoid cells can become

t cell or b cell

help immune system stay strong

myeloid cells can become

platelets

eosinophils

basophils

neutrophil

monocyte

erythrocyte

what are controllable factors for heart attack risk factors

smoking, obesity, inadequate exercise, emotional stress, alcohol n

on controllable factors for heart attack risk factors

age, genetics, homocysteine

doppler ultrasonography

used to see blood flow pattern. this can be used to view blood flow in the kidneys, placenta, and the heart

angiogram

x ray of blood vessels taken in rapid succession following injection of radio opaque substance in vessel

it defines size and shape of arteries and veins in organs or tissue and is used to define tumors of the aorta

angioplasty

process of surgically repairing a blood vessel to restore normal blood flow to the heart

can be laser, balloon, and transluminal extraction catheter

p wave is caused by

the depolarization of the atrium muscle that causes chamber contraction

q,r,s,t waves are related to

ventricles

ABCs of CPR

a-open airway

b- restore breathing

c- restore circulation

what is anemia

reduction of red blood cells or blood volume

causes of anemia

considered a symptom of other disease like sickle cell anemia

deficiency of iron and or bone marrow malfunction can also be causes
