Bicuspid/Mitral valve

Btwn. left atrium and Left ventricle. left side of heart

Left Smilunar/Aortic valve

Enterance to aorta left side of heart. Largest Artery

Layers of Blood Vessel

Tunica adventitia (external) outer layer. Tunica media middle layer. Tunica intima inner layer (interna)

(SA) node

sinoatrial node, initiates electric impulse,pacemaker

(AV) node

atrioventricular node, fibers relay impulses, bundle of his

Tricuspid Valve

btwn right atrium and right ventricle, right lower heart

empoism

obstruction of blood vessels by emolus

embolus

blood clot or undissolved matter circulating in bloodstream

phlebitis

inflamation of a vein

capillaries

one cell thick vessels form bridge btwn arterial and venous circulation

antecubital

area of arm anterior in front of and below elbow, several veins here, vein arrangements h and m

median cubital vein

near center of anticubital vein, first choice, usually larger, close to surface, staionary

Blood vessels

tube like expand and contract, arteries,veins,capillaries.

arterioles

smallest branches of arteries, join cappillaries

lumen

internal space of blood vessels where blood flows

great saphenous

longest vein in body

arteries

carry blood away from heart, thick walls, blood is under pressure, no bounce.

two divisions of circulation

pulmonary circulation: carries blood from right ventricle to lungs to remove carbon dioxide and pick up oxygen and returns oxygenated blood to left atrium. systemic circulation: serves the rest of the body carring oxygenated blood from left ventricle returns to right atrium with dirty blood.

pulmonary artery

only artery carries deoxygenated blood from heart to lungs

chambers of the heart

upper chamber: right and left atrium, recieves deoxygented blood. Lower chamber: right and left ventricle: pumps and delivers blood.

layers of the heart

Epicardium- outer, endocardium- inner, myocardium- middle

systal/disystal

contraction,relaxation

veins

return blood low in oxygen, thin walls, no pulse.

vena cava

largest vein in the body

circulatory system

The means by which oxygen and food are carried and the way carbond dioxide and waste are carried to excretory organs, kidneys, lungs, skin,coagulates blood, regulates body temp.

two parts of circulatory system

cardiovascular system: heart,blood,blood vessels, Lymphatic system: lymph,lymph vessels, nodes

Arrhythmias

bracardia- slow beats >60, tacacardia- fast beats <100, Extrasystole- extra beats, fibrillation- rapid uncoordinated beats.

pericardium

fluid filled sac that surrounds the heart

thrombus

blood clot

Basilic vein

vein located on medial aspect, inner side, of anticubital, last choice, easy to palpate, not well anchord, rolls, close to major artery.

Cephalic vein

located in lateral aspect of anticubital area, second choice, harder to palpate, fairly anchord

right semilunar/pulmonary valve

entrance to pulmonary artery, right upper heart
