Heart
The Center of the cardiovascular system, wt. 300g, circulated the blood through the heart, lungs, and the rest of the body.
Arteries
Branching system of vessels that transports blood from the right and left ventricles to all body parts. Transports blood away from the heart.
Veins
Transports blood from peripheral tissues back to the heart
Capillaries
Microscopic blood vessels that connect arterioles with venues; facilitate passages of life-sustaining fluids containing oxygen and nutrients to cell bodies and the removal of accumulated waste and carbon dioxide
Blood
Fluid consisting of formed elements and plasma. Specialized bodily fluid that delivers necessary substances to the body’s cells. Blood is circulated through blood vessels by the pumping action of the heart.
Endocardium
Inner lining of the heart.
Myocardium
Muscular middle layer of the heart
Pericardium
The outer membranous sac surrounding the heart
Septum
The divider of the right and left sides of the heart
Atria
The upper chambers of the heart
Ventricles
The lower chambers of the heart
Right atrium
Upper right portion of the heart.
Superior vena cava and inferior vena cava
Bring deoxygenated blood into the right atrium
Rt. ventricle
Right lower portion of the heart. It receives blood from the rt. atrium through the tricuspid valve
Pulmonary artery
The only artery in the body to carry deoxygenated blood.
Left atrium
Receives oxygen rich blood from the lungs via the right and left pulmonary veins. The pressure from the oxygen forces open the bicuspid (mitral) valve and fills the left ventricle
Left Ventricle
Left lower portion of the heart. It receives blood from the left atrium through the mitral valve or bicuspid valve. The oxygenated blood from the LV flows through the aortic valve and into the aorta to all parts of the body.
Tricuspid or right atrioventricular valve
Guards the opening between the right atrium and right ventricle
Pulmonary (semilunar) valve
The exit point for blood leaving the right ventricle
Bicuspid or mitral valve
The valve between the left atrium and ventricle
Aortic or semilunar valve
Blood exits the left ventricle through this between the left ventricle and aorta
Anastomosis
Surgical condition between blood vessels or the joining of one hollow or tubular organ to another.
Aneurysm
Abnormal widening or ballooning of a portion of a artery due to weakness in the wall of the blood vessel.
Angiogram
X-Ray record of the size, shape and location of the heart and it’s blood vessels after radiopaque contrast
Angioplasty
Surgical repair of a blood vessel
Arrhythmia
Loss of rhythm of the heartbeat, also called dysrhythmia.
Arteriosclerosis
Hardening of arteries.
Atheroma
Tumor of a artery containing a fatty substance
Auscultation
Method of physical assessment using a stephoscope to listen to the sounds within the chest.
