Parts of the Heart Crossword
18
pericardial cavity : The heart sits within a fluid-filled cavity called the
Epicardium : is the outermost layer of the heart wall and is just another name for the visceral layer of the pericardium.
Myocardium : is the muscular middle layer of the heart wall that contains the cardiac muscle tissue.
Endocardium : is the simple squamous endothelium layer that lines the inside of the heart.
Atrioventricular valves : are located in the middle of the heart between the atria and ventricles and only allow blood to flow from the atria into the ventricles.
tricuspid valve : The AV valve on the right side of the heart is called the ---- because it is made of three cusps (flaps) that separate to allow blood to pass through and connect to block regurgitation of blood.
mitral valve : The AV valve on the left side of the heart is called the -----or the bicuspid valve because it has two cusps.
chordae tendineae : pulls on the AV valves to keep them from folding backwards and allowing blood to regurgitate past them.
Semilunar valves : named for the crescent moon shape of their cusps, are located between the ventricles and the arteries that carry blood away from the heart.
pulmonary valve : The semilunar valve on the right side of the heart is the
aortic valve : named for the fact that it prevents the aorta from regurgitating blood back into the left ventricle.
superior vena cava : one of the two major paths into which the veins from all parts of the body (except from the lungs back to the heart) converge to lead to the right atrium of the heart.
Purkinje fibers : carry the signal to the walls of the ventricles, stimulating the cardiac muscle cells to contract in a coordinated manner to efficiently pump blood out of the heart.
Systole : cardiac muscle tissue is contracting to push blood out of the chamber.
Diastole : the cardiac muscle cells relax to allow the chamber to fill with blood.
Atrial systole : the atria contract and push blood into the ventricles.
Ventricular systole : the ventricles contract to push blood into the aorta and pulmonary trunk.
Relaxation phase : all 4 chambers of the heart are in diastole as blood pours into the heart from the veins.
