cardiovascularsystem consists of the heart, blood, vessels
pericardium known as the pericardial sac double-walled membranous sac that encloses the heart
epicardium is the external layer of the heart and inner layer of the pericardium
myocardium also known as myocardial muscle is the middle and thickest of the heart's three layers and consists of specialized cardiac muscle tissue. This muscle maintains the flow of blood throughout the body
endocardium which consists of epithelial tissue it is the inner lining of the heart. This surface comes into direct contact with the blood as it is being pumped through the heart.
atria two upper chamber of the heart. They are the receiving chambers and all blood vessels coming into the heart enter here.
Septum is a wall that separates two chanbers
ventricles are the lower chambers of the heart. They are the pumping chambers, and all blood vessels leaving the heart emerge from the ventricles
Tricuspid controls the opening between the right atrium and the right ventricle.. means having three cusps
pulmonary semilunar valve located between the right ventricle and the pulmonary artery.
pulmonary means pertaining to the lungs
semilunar means half moon shaped like a half moon
mitral valve also known as the bicuspid valve is located between the left atrium and left venticle. Biscupid means having two cusps
aortic semilunar is located between the left ventricle and aorta
pulmonary circulation is the flow of blood only between the heart and lungs
pulmonary arteries carry deoxygenated blood out of the right ventricles and into the lungs. This is the only place in the body where deoxygenated blood is carried by arteries instead of veins
pulmonary veins carry the oxygenated blood from the lungs into the left atrium of the heart. This is the only place in the body where veins carry oxygenated blood
systemic circulation includes the flow of blood to all parts of the body except the lungs
Sinoatrial node establishes the basic rhythm and rate of the heartbeat (natural pace maker)
atrioventricular node transmits the electrical impulses onward to the bundle of His
bundle of HIs fibers that carry electrical impulse to ensure to insure the sequence of the heart contractions
purkinje fibers This contraction of the ventricles forces blood out of the heart and into the aorta and pulmonary arteries
arteries are large blood vessels that carry blood away from the heart to all regions of the body
Neutrophils formed in the red bone marrow are the most common type of WBC
Basophils are the least common and are responsible for the symptoms of allergies
Eosinophils they destroy paraasitic organisms and paly a major role in allergic reactions
Lymphocytes they identify foreign substances and germs in the body (bacteria or viruses) they produce antibodies that specifically target them
Monocytes they provide immunological defenses against many infectious organisms
aneurysm is a localized weak spot or ballon like enlargement of the wall of an artery. Can be fatal
ateriosclerosis hardening of the arteries
Chronic venous insufficiency circulation is inadequate due to partial vein blockage or leakage of venous valves effects the feet and ankles causes discoloration of the skin
phlebitis inflammation of a vein occurs in superficial vein
varicose veins abnormally swollen veins occur when valves in the veins malfunction and allow blood to pool in these veins causing them to enlarge
thrombosis is the abnormal condition of a having a thrombus
thrombus is a blood clot attached to the interior wall of an artery
thrombotic occlusion is the blocking of an artery by a thrombus
coronary thrombosis is damage to the heart muscle caused by a thrombus blocking a coronary artery
deep vein thrombosis is the condition of having a thrombus attached to the wall of a deep vein blockage can form in the legs example sitting to long on a airplane it can break loose and be fatal
embolism is the sudden blockage of a blood vessel by an embolus
embolus is a foreign object such as a blood clot quantity of air or gas or a bit of tissue or tumor tha is circulating in the blood
Blood dyscrasia is any pathologic condition of the cellular elements of the blood
Hemochromatosis is a genetic disorder in which the intestines absorb too much iron
leukopenia that the number of leukocytes in the blood are less than normal
polycythemia is an abnormal increase in the number of red cells in the blood due to excess production of bone marrow
Septicemia blood poisoning/ is a systemic condition caused by the spread ob microorganisms and their toxins via the circulating blood
Thrombocytopenia is a condition in which there is an abnormally small number of platelets circulating in the blood
Thrombocytosis is an abnormal increase in the number of platelets in the circulating blood
hemmorrahage is the loss of a large amount of blood in a short time
transfusion reactions is a serious and potentially fatal complication of a blood transfusion when a patients blood does not match
Cholesterol fatty substance that travels through the blood and is found in all parts of the body
heyperlipidemia is elevated levels of cholesterol and fatty substances
myelodysplastic bone marrow disorders
leukemia type of cancer found in blood forming tissues, other organs and in circulating blood
Anemia is a lower than normal number of erythrocytes it means inadequate hemoglobin which means all parts of the body receives less oxygen
Aplastic failure of blood cell productions leads to fatigue and weakness
Hemolytic anemia is a condition of an inadequate number of circulating red blood cells due to the premature destruction of red cells by the spleen
Iron deficiency anemia common form of anemia Iron is essential component of hemoglobin blood can not carry oxygen effectively
