Question | Answer |
Heart | muscular cone-shaped organ the size of a fist, located behind the sternum (breast bone) and between the lungs. |
Atrioventricular Valves | consist of the tricuspid and mitral valves, which lie between the right atrium and the right ventricle and the left atrium and left ventricle, respectively. |
semilunar valves | pulmonary and aortic valves located between the right ventricle and the pulmonary artery and between the left ventricle and the aorta, respectively. |
pericardium | two-layer sac surrounding the heart, consisting of an external fibrous and an internal serous layer. The serous layer secretes a fluid that facilitates movement of the heart. |
Three Layers of the Heart | epicardium, myocardium, endocardium |
epicardium | covers the heart |
myocardium | middle, thick, muscular layer |
endocardium | inner lining of the heart |
blood vessels | tubelike structures that carry blood away from the heart. |
arteries | blood vessels that carry blood away from the heart. |
pulmonary artery | carries carbon dioxide and other waste products from the heart to the lungs. |
arterioles | smallest arteries |
aorta | largest artery in the body, originating at the left ventricle and descending through the thorax and abdomen. |
veins | blood vessels that carry blood back to the heart. |
Pulmonary veins | carry blood containing carbon dioxide and other waste products. Carry oxygenated blood from the lungs to the heart. |
venules | smallest veins |
venae cavae | largest veins in the body. |
inferior vena cava | carries blood to the heart from body parts below the diaphragm. |
Superior vena cava | returns the blood to the heart from the upper part of the body. |
capillaries | microscopic blood vessels that connect arterioles with venules. |
Blood | composed of plasma and formed elements, such as erythrocytes, leukocytes, and thrombocytes. |
plasma | clear, straw-colored, liquid portion of blood in which cells are suspended. Plasma is approximately 90% water and comprises approximately 55% of the total blood volume. |
erythrocytes | red blood cells that carry oxygen. Erythrocytes develop in bone marrow. |
leukocytes | white blood cells that combat infection and respond to inflammation. There are five types of white blood cells. |
platelets (thrombocytes) | one of the formed elements in the blood that is responsible for aiding in the clotting process. |
serum | clear, watery fluid portion of the blood that remains after a clot has formed. |
lymph | transparent, colorless, tissue fluid that, on entering the lymphatic system, is called lymph. It contains Lymphocytes and monocytes that flows in a one-way direction to the heart. Lymph is similar to blood plasma. |
lymphatic vessels | similar to veins, lymphatic vessels transport lymph from body tissues to the chest, where it enters the cardiovascular system. |
lymph nodes | small, spherical bodies composed of lymphoid tissue. |
Spleen | located in the left side of the abdominal cavity between the stomach and the diaphragm. |
thymus gland | one of the primary lymphatic organs, it is located anterior to the ascending aorta and posterior to the sternum between the lungs. |
angi/o | vessel (usually refers to blood vessels) |
aort/o | aorta |
arteri/o | artery |
atri/o | atrium |
cardi/o | heart |
lymph/o | lymph, lymph tissue |
lymphaden/o | lymph node |
myel/o | bone marrow |
phleb/o, ven/o | vein |
plasm/o | plasma |
splen/o | spleen |
thym/o | thymus gland |
valv/o, valvul/o | valve |
ventricul/o | ventricle |
ather/o | yellowish, fatty plaque |
ech/o | sound |
electr/o | electricity, electrical activity |
isch/o | deficiency, blockage |
therm/o | heat |
thromb/o | clot |
brady- | slow |
-ac | pertaining to |
-apheresis | removal |
-graph | instrument used to record; record |
-penia | abnormal reduction in number |
-poiesis | formation |
-sclerosis | hardening |
angioma | tumor composed of blood vessels |
angiostenosis | narrowing of a blood vessel |
aortic stenosis | narrowing, pertaining to aorta |
arteriosclerosis | hardening of the arteries |
atherosclerosis | hardening of fatty plaque |
bradycardia | condition of a slow heart (rate less than 60 beats per minute) |
cardiomegaly | enlargement of the heart |
cardiomyopathy | disease of the heart muscle |
endocarditis | inflammation of the inner (lining) of the heart (particularly heart valves) |
ischemia | deficiency of blood (flow) |
myocarditis | inflammation of the muscle of the heart |
pericarditis | inflammation of the sac surrounding the heart |
phlebitis | inflammation of a vein |
polyarteritis | inflammation of many (sites in the) arteries |
tachycardia | condition of a rapid heart (rate of more than 100 beats per min) |
thrombophlebitis | inflammation of a vein associated with a clot |
valvulitis | inflammation of a valve (of the heart) |
hematoma | tumor of blood (collection of blood resulting from a broken blood vessel) |
multiple myeloma | tumors of the bone marrow |
pancytopenia | abnormal reduction of all (blood) cells |
thrombosis | abnormal condition of a (blood) clot |
thrombus | (blood) clot (attached to the interior wall of an artery or vein) |
lymphadenitis | inflammation of the lymph nodes |
lymphadenopathy | disease of the lymph nodes (characterized by abnormal enlargement of the lymph nodes associated with an infection of malignancy) |
lymphoma | tumor of lymphatic tissue (malignant) |
splenomegaly | enlargement of the spleen |
thymoma | tumor of the thymus gland |
acute coronary syndrome (ACS) | sudden symptoms of insufficient blood supply to the heart indicating unstable angina or acute myocardial infarction |
aneurysm | ballooning of a weakened portion of an arterial wall |
angina pectoris | chest pain, which may radiate to the left arm and jaw, that occurs when there is an insufficient supply of blood to the heart muscle. |
arrhythmia | any disturbance or abnormality in the heart's normal rhythmic pattern. |
atrial fibrillation (AFib) | a cardiac arrhythmia characterized by chaotic, rapid electrical impulses in the atria. |
cardiac arrest | sudden cessation of cardiac output and effective circulation, which requires cardiopulmonary resuscitation (CPR) |
cardiac tamponade | acute compression of the heart caused by fluid accumulation in the pericardial cavity. |
coarctation of the aorta | congenital cardiac condition characterized by a narrowing of the aorta. |
congenital heart disease | heart abnormality present at birth |
congestive heart failure | inability of the heart to pump enough blood through the body to supply the tissues and organs with nutrients and oxygen. |
coronary artery disease | a condition that reduces the flow of blood through the coronary arteries to the myocardium, denying the myocardial tissue of sufficient oxygen and nutrients to function fully |
coronary occlusion | obstruction of an artery of the heart, usually from atherosclerosis. |
deep vein thrombosis | condition of thrombus in a deep vein of the body. |
