Chambers of the Heart Overview
The heart is the muscular pump of the vascular system
Superior Vena Cava
Carries deoxygenated blood from the head and arms and chest and empties into the right atrium, formed by the union of the right and left brachiocephalic veins?
Inferior Vena Cava
receives blood from lower limbs and abdominal organs and empties into the posterior part of the right atrium of the heart, formed from the union of the two iliac veins
The upper right chamber of the heart, where deoxygenated blood is received from the vena cava and then sent to the right ventricle. Receives blood from the body, the blood is low in oxygen and high in waste produce carbon dioxide
the chamber on the right side of the heart that receives venous (deoxygenated) blood from the right atrium and pumps it into the pulmonary trunk., and then pumped out through the pulmonary artery toward the lungs.
A-V Tricuspid Valve
valve between the right atrium and the right ventricle
R-V Chordae Tendineae
"heart strings" are tiny white collagenic cords that anchor the cusps to the ventricular walls. They originate from the right papillary muscles., cords between right valve cusps and right papillary muscles
R-V Papillary Muscle
specialized muscles that attach the right ventricles to the cusps of the valves by strands called chordae tendineae cordis.
any of four veins that carry arterial blood from the lungs to the left atrium of the heart, Carries oxygenated blood from the lungs to the heart
the left upper chamber of the heart that receives blood from the pulmonary veins, receives oxygenated blood from the lungs
the chamber on the left side of the heart that receives arterial blood from the left atrium and pumps it into the aorta
A-V Bicuspid (Mitral) Valve
gateway between left atrium and left ventricle, A valve between the left atrium and ventricle. It prevents blood from flowing backwards into the atrium. It has two cusps or flaps.
L-V Chordae Tendineae
"heart strings" are tiny white collagenic cords that anchor the left cusps to the ventricular walls. They originate from the left papillary muscles.
L-V Papillary Muscle
specialized muscles that attach the left ventricles to the cusps of the valves by strands called chordae tendineae cordis.
the ascending part of the aorta as it emerges from the left ventricle, Branches off the left ventricle; carries oxygen rich blood to parts of the body above the heart
the artery that carries venous (deoxygenated) blood from the right ventricle of the heart and divides into the right and left pulmonary arteries
two arteries (branches of the pulmonary trunk) that carry venous (deoxygenated) blood from the heart to the lungs
Pulmonary Semilunar Valve
heart valve opening from the right ventricle to the pulmonary artery
Aortic Semilunar Valve
The valve that leaves or exits the left ventricle opening/entering the aorta, allows blood to flow into the aorta and prevents its return to the ventricle
blood vessels located between ascending and descending aortas that deliver blood to most of the upper body
A continuation of the aortic arch as it descends through the thoracic (chest) cavity to the diaphragm. It is a very large vessel and divides into major branches to the organs and muscles of the chest. Numerous branches supplying oxygen to the chest branch off the thoracic aorta.
The first major branch off of the aorta and the major artery to the forelimbs and head.
Left Common Carotid Artery
second branch of the aortic arch, Branches from the aorta; transports blood to the left side of the head and neck
Left Subclavian Artery
Third branch of the aortic arch that distributes blood to the left arm, an artery that arises independently from the aorta and just to the left of the brachiocephalic trunk
