Cardiovascular System

Heart, blood vessels, blood

Between lungs and about dyaphram

• upper champer- all vessels coming into the heart go to the artium
• the recieving champer of the heart are the atrium chamber

seperating wall b/w the 2 atria

• lower champer of the heart, pumping champer
• all the vessels that leave the heart come from the ventricles

wall that seperates the right and left ventricles

a narrow tip of the heart

ventricles

control the flow of blood through the heart

controls the opening b/w the right atrium and right ventrical

located b/w the right ventical and the pulmonary artery

located b/w the left artium and the left ventrical

located b/w the left ventrical and the aorta

valve

• the starting and spredding contracting impulses
• made of four masses of specialized cells

• SA node
• measures P atrium

• AV node
• measures Q atrium

• AV bundle
• Measures atrium QRS

measures atrium T

• SA node
• AV node
• AV bundle
• PJ

when the vessels slam shut b/w the artria and ventricles closer of the tricuspid and the mitrovalve and the beginning

at the end of systolic- shorter and higher pitched, caused by the semilunlar valve that are closingin the aorta and pulmonary arties

includes the flow of blood through the right ventrical, pulmonary arterial system, lungs, left atrium, and pulmonary venus system

blood flow to all parts of the body except the lungs; including arties, veins, and capillaries

• large vessels that carry blood away from the heart to all regions of the body
• contains oxygen, nutrients, and other vital products

vessels or blood

arteries

largest artiery of the heart, begins at the left ventrical of the heart

arteries

pert. to interior of the artery

branches from the aorta. supplies blood to the heart muscle

crown, coronary

• smaller branches of the artery. thinner than the arteries
• carries blood to capillaries

pert. to

the exchange of gases in the lunges takes place b/w the aveoli and the capillaries

low-pressure collecting system, returns waste filled blood to the heart

vein

small veins that join together to form veins

carries

small opening in the artial septum of the fetus that closes immediatly after birth

• EKG
• recording of the electical activity of the myocardium

imagining technic used to display soft tissue structures such as blood vessels w/o confessing overlay of the bone images

the graft that repel heart sounds

finger stick

condition where theres abnormal fluid retention where the heart is unable to maintain enough circulation

localized area of necrosis in an organ or tissue caused by an interruption of blood supply

sufficating pain, caused by lack of supply of oxygen to the myocardium

conditionof myocardium caused by a lack of oxygen reaching the tissue cells

deficiency of blood supply to circulatlory obstuct

temp. interruption in the blood supply to the brain

bacteria is the most common cause if the infection of endocarditis

obstuction of the mital valve

caused by the disease rheumatic fever w/ damage done to the valve

dysrrhythmia- abnormal heart rhyms

pounding or racing of the heart

rapid, random, ineffective contraction

muscular twitting; quivering, shivering and muscular contractions

artial contractions are rapid but regular

a fast heart beat of a sudden onset

spasm or convulsion

abnormal condition that effects the arteries of the heart caused by plaque; usu. get angina w/ CAD

abnormal condition that effects the blood vessels outside the heart; lymphatic vessels

inflammion of blood or lymph vessel

plaque

locatized ballooning which causes an enlargement of the artery

involuntary contraction

narrowing of any blood vessel, esp. the aorta

tumor made up of newly formed blood

swallon veins

• condition in which a blood clot formed attached to the internal way of the artery embolus
• drugs used to destroy clot and tissue plasmicatic activate (TPA)

block and demage of the heart caused by a blood clot

open vessel

any type of forgein object- air, gas, piece of tissue

a mass of undesolved matter circulating until it becomes lodged in a vessel

consists of attaches of pailness, cyanosis, and redness of the fingers and toes usu. indicated by emotion, stress, or cold temp.

defisiatence of blood passing through an organ or body part

mixture or blending

nosebleed

throwing up of blood

blood poisoning

lack of the factors that are needed to clot blood

together the combind w/ protein to form lipoprotein; liver cynthosises

protein

orange or yellowish pigment in the bile

absence of a formet blood element

shortened survival of red blood cells

short lived red blood cells

not enough iron in body

genetic defect of the hemoglobin causing a sickle shape

primary or idopathic

BP can be controlled once problem is cured

sudden onset of high blood pressure, damage to blood vessels such as brain, retina

used to lower BP

contol bleed

removal of the lining of hte neck artery

surgical joining of ducts or blood vessesl

incison into vein to draw blood or start IV

electrical shock through the chest wall to restore normal rhythm

constricting band

procedure of seperation of plasma from elements of the blood

slows blood cloting and prevents new clots

• antibotic used to stop infection before minor surgeries
• ex. rootcanal, tooth surgery
