muscular cone-shaped organ the size of a fist, located behind the sternum (breast bone) and between the lungs. The pumping action of this organ circulates blood throughout the body.
The upper chambers of the heart that receive blood returning from the body through the veins.
The lower chambers of the heart that pump blood through the arteries from the heart back to the body tissues.
located between the right atrium and right ventricle
located between the left atrium and left ventricle
pulmonary and aortic valves located between the right ventricle and the pulmonary artery between the left ventricle and aorta
two-layer sac consisting of an external fibrous and internal serous layer. The serous layer secretes a fluid that facilitates movement of the heart. This layer also covers the heart and is called the epicardium.
covers the heart
middle, thick, muscular layer
inner lining of the heart
tubelike structures that carry blood throughout the body
blood vessels that carry blood AWAY from the heart; oxygen and nutrients from the heart to the body cells
largest artery in the body, originating at the left ventricle and descending through the thorax and abdomen
blood vessels that carry blood BACK TO THE HEART; waste products
largest veins in the body
microscopic blood vessels that connect arterioles with venules. Materials are passed between the blood and tissue through capillary walls.
composed of plasma and formed elements such as erythrocytes, leukocytes, and thrombocytes
clear, straw-colored, liquid portion of blood in which cells are suspended. Plasma is ~90% water and comprises 55% of the total blood volume
red blood cells that carry oxygen; developed in the bone marrow
white blood cells tat combat infection and response to inflammation; there are five types
one of the formed elements in the blood that is responsible for aiding in the clotting process
clear, watery fluid portion of the blood that remains after a clot has formed
transparent, colorless, tissue fluid that, on entering the lymphatic system, is called lymph; contains lymphocyte and monocytes and flows in one-way direction to the heart.
transport lymph from body tissues to the chest where it enters the cardiac system
small, spherical bodies composed of lymphoid tissue; filter lymph to keep substances such as bacteria and other foreign agents from entering the blood
located in the left-side of the abdominal cavity between the stomach and diaphragm; the largest lymphatic organ in the body; stores blood and destroys worn out RBCs
important role in the development of the body's immune system (infancy to puberty)
vessel (usually refers to blood vessel)
lymph, lymph tissue
yellow, fatty plague
electricity, electrical activity
instrument used to record; record
abnormal reduction in number
tumor composed of blood vessels
narrowing of blood vessel
narrowing pertaining to aorta
hardening of arteries
hardening of fatty plague
condition of slow heart (< 60 beats/minute)
pain in the heart
enlargement of the heart
disease of the heart muscle
inflammation of the valves of the heart
inflammation of the inner lining of the heart
deficiency of blood flow
inflammation of the muscle of the heart
inflammation of the sac surrounding the heart
inflammation of a vein
inflammation of many (sites in the) arteries
abnormal state of rapid heart (> 100 beats/minute)
inflammation of a vein associated with a clot
tumors of bone marrow
abnormal reduction of all blood cells
abnormal condition of a blood clot
blood blot attached to the interior wall of an artery or a vein
inflammation of the lymph nodes
disease of the lymph nodes
tumor of lymphatic tissue
enlargement of the spleen
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
ballooning of a weakened portion of an arterial wall
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
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.
sudden cessation of cardiac output and effective circulation which requires CPR
acute compression of the heart caused by fluid accumulation in the pericardial cavity
coarctation of the aorta
congential cardiac condition characterized by a narrowing of the aorta
congenital heart disease
heart abnormality present at birth
congestive heart failure (CHF)
inability of the heart to pump enough blood through the body to supply the tissues and organs with nutrients and oxygen
coronary artery disease (CAD)
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; caused by artherosclerosis
obstruction of an artery of the heart, usually from arthersclerosis.
deep vein thrombosis (DVT)
condition of thrombus in a deep vein of the body.
