components of the cardiovascular system

functions of the cardiovascular system

sac that encloses the hear

outer layer of the sac surrounding the heart

inner layer of the sac surrounding the heart, forms the outer layer of the heart

external layer of the heart

middle layer of that heart that consists of specialized cardiac muscle tissue

inner lining of the heart

supply oxygen rich blood to myocardium

flow of blood only between the heart and lungs

carry deoxygenated blood out of R ventricle and into lungs, only place in the body where deoxygenated blood is carried by arteries instead of veins

carry oxygenated blood from the lungs into the L atrium

includes the flow of blood to all parts of the body except the lungs

node located in the posterior wall of the R atrium

node located on the floor of the R atrium near the interatrial septum

group of fibers located with the interventricular septum

fibers located in the walls of the ventricles

due to the stimulation of atria

shows the stimulation of the ventricles

recovery of the ventricles

large blood vessels that carry blood away from the heart to all regions of the body

inner portion of an artery or within an artery

largest blood vessel in the body

major arteries that carry blood upward to the head

thinner branches of arteries that carry blood to the capillaries

form a low pressure collecting system to return oxygen poor to the heart

smaller veins that join to form larger veins

2 largest veins in the body, return blood into the heart

transports blood from the upper portion of the body to the heart

transports blood from the lower portion of the body

smallest blood vessels in the body, delivering oxygen and nutrients to the cells in tissues

rhythmic pressure against the walls of an artery caused by the contraction of the heart

measurement of systolic and diastolic pressure exerted against walls of arteries

plasma fluid after the blood cells and the clotting proteins have been removed

iron containing pigment of RBCs to transport oxygen

most come WBC, formed in the red bone marrow

formed in the red blood marrow then migrates to tissues

formed in the red bone marrow, responsible for allergy symptoms

formed in the red bone marrow, lymph nodes and spleen.

formed in the red bone marrow, lymph nodes and the spleen, provide immunological defenses

important and blood clotting, platelets

substance that the body regards as being foreign

diagnosing and treating blood and blood diseases

specializes in diagnosing, medical management and surgical treatment of disorders of blood vessels

structural abnormalities caused by the failure of the heart to develop normally before birth

atherosclerosis of the coronary arteries that reduces the blood supply to the heart muscle

hardening and narrowing of the arteries caused by a buildup of cholestrol plaque on the interior walls of the arteries

group of disabilities resulting from an insufficient supply of oxygenated blood to the heart

episodes of severe chest pain due to inadequate blood flow to the myocardium

occlusion of 1 or more coronary arteries caused by plaque buildup, heart attack

heart is unable to pump out all of the blood that it receives

heart failure that causes accumulation of fluid in the lungs, pulmonary edema

failure that causes fluid buildup beginning with feet and legs

abnormal enlargement of the heart

disease of the heart muscle that causes the heart to become enlarged and to pump less strongly

abnormal protrusion of the heart valve that results in the inability of valve to close completely

heart abruptly stops or develops a very abnormal arrhythmia that prevents it from pumping blood

normal rhythmic contractions of the atria are replaced by rapid irregular twitching of heart wall, A fib

rapid irregular and useless contractions of the ventricles

very rapid heart beat that begins with in the ventricles

benign tumor made up of newly formed blood vessels

disorders of blood vessels located outside the heart and brain

periphral vascular diseased caused by athersclerosis

weak spot or balloon like enlargement of wall of artery

venous circulation is inadequate due to partial vein blockage or leakage of venous veins

abnormal condition of having a thrombus

blood clot attached to interior wall of vein/artery

blocking of artery by thrombus

damage to heart muscle caused by thrombus blocking coronary artery

sudden blockage of a blood vessel by an embolus

foreign object that is circulating in the blood

pathologic condition of the cellular elements of the blood

disorder in which the intestines absorb too much iron

less than normal WBCs

abnormal increase in the number of red cells in the blood due to excess production of those cells by bone marrow

blood poisoning

abnormally small number of platelets circulating in the blood

abnormal increase in the number of platelets in the circulating blood

fatty substance travels thru the blood and is found in all parts of the body

elevated level of cholesterol

lower than normal number of RBCs

absence of all formed blood elements caused by the failure of blood cell production to the bone marrow

inadequate number of circulating RBCs due to premature destruction of RBCs of the spleen

condition with larger than normal RBCs

caused by lack of the protein intrinsic factor that helps the body absorb vit b12 from gastrointestinal tract

caused abnormal hemoglobin, resulting in some RBCs assuming an abnormal sickle shape

causes mild or severe anemia due to reduced hemoglobin and fewer rbcs than normal

slows coagulation and prevents new clots from forming

dissolves or causes a thrombus to break up

causes blood vessels to narrow

causes blood vessels to expand

surgical removal of the lining of a portion of a clogged carotid artery leading to the brain

requires opening the chest, a piece of vein from leg or chest is implanted on the heart to replace a blocked coronary artery and to improve the flow of blood to the heart
