Muscular cone-shaped organ the size of a fist, located behind the sternum and between the lungs.
Circulates blood throughout the body.
Two upper chambers, the right and left atrium, and two lower chambers, the right and left ventricle.
located between the right ventricle and the pulmonary artery and between the left ventricle and the aorta.
Two-layer sac surrounding the heart, consisting of an external fibrous and an internal serous layer.
One of the formed elements in the blood that is responsible for aiding in the clotting process.
Similar to veins.
Transport lymph from body tissues to the chest, where it enters the cardiovascular system. Provide a one-way flow for lymph where lymph enters through veins into the circulatory system.
Small, spherical bodies composed of lymphoid tissue.
Filter lymph to keep substances such as bacteria and other foreign agents from entering the blood.
One of the primary lymphatic organs, located anterior to the ascending aorta and posterior to the sternum between the lungs.
inflammation of the inner (lining) of the heart (particularly heart valves) deficiency of blood (flow)
disease of the lymph nodes (characterized by abnormal enlargement of the lymph nodes associated with an infection or malignancy)
acute coronary syndrome (ACS)
sudden symptoms of insufficient blood supply to the heart indicating unstable angina or acute myocardial infarction
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.
atrial fibrillation (AFib)
a cardiac arrhythmia characterized by chaotic, rapid electrical impulses in the atria. The atria quiver instead of contracting, causing irregular ventricular response and the ejection of a reduced amount of blood.
sudden cessation of cardiac output and effective circulation, which requires cardiopulmonary resuscitation (CPR)
acute compression of the heart caused by fluid accumulation in the pericardial cavity
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 thought the coronary arteries to the myocardium, denying the myocardial tissue of sufficient oxygen and nutrients to function fully; most often caused by coronary atherosclerosis.
obstruction of an artery of the heart, usually from atherosclerosis. Coronary occlusion can lead to acute myocardial infarction.
deep vein thrombosis (DVT)
condition of thrombus in a deep ein of the body. Most often occurs in the lower extremities.
pain and discomfort in calf muscles while walking; a condition seen in peripheral arterial disease.
mitral valve stenosis
a narrowing of the mitral valve from scarring, usually caused by episodes of rheumatic fever
myocardial infraction (MI)
death (necrosis) of a portion of the myocardium caused by lack of oxygen resulting from an interrupted blood supply (heart attack)
peripheral arterial disease (PAD)
disease of the arteries in the arm and legs, resulting in narrowing or complete obstruction of the artery.
rheumatic heart disease
damage to the heart muscle or heart valves caused by one or more episodes of rheumatic fever
reduction in the number of red blood cells.
Caused by blood loss or decrease in the production or increase in the destruction of red blood cells.
blood clot or foreign material, such as air or fat, that enters the bloodstream and moves until it lodges at another point in the circulation.
inherited bleeding disease most commonly caused by a deficiency of the coagulation factor VIII
malignant disease characterized by excessive increase in abnormal white blood cells formed in the bone marrow
a condition in which pathogenic microorganisms, usually bacteria, enter the bloodstream, causing a systemic inflammatory response to the infection
malignant disorder of the lymphatic tissue characterized by progressive enlargement of the lymph nodes, usually beginning in the cervical nodes
