cardiovascular system
auricles
are extensions of the atria which look like puppy ears, they are lined by trabeculae carneae
trabeculae carneae
are ridges that slow blood flow and decrease splashing; located in both ventricles
chordae tendineae
attach the right and left atrioventricular valves to the papillary muscles for reinforcement and to prevent prolapse
are extensions of the atria which look like puppy ears, they are lined by pectinate muscles
auricles
left atrioventricular valve is also known as...
bicuspid and mitral valve; are reinforced by chordae tendineae; oxygenated blood passes thru
attach the right and left atrioventricular valves to the papillary muscles for reinforcement and to prevent prolapse
chordae tendineae
help keep both left and right atrioventricles from prolapsing; attach to papillary muscles; found only in atrioventricular valves
chordae tendineae
pectinate muscles
help direct the flow of blood; located in both auricles and the right atrium
chordae tendineae
help keep both left and right atrioventricles from prolapsing; attach to papillary muscles; found only in atrioventricular valves
mitral valve is also known as...
left atrioventricular and bicuspid valve
bicuspid valve is also known as...
left atrioventricular and mitral valve
papillary muscles
located in both right and left ventricles, chordae tendineae attach to them to reinforce atrioventricular valves and prevent prolapse.
What is blood pressure?
measuring systolic pressure; the top number is when the ventricles contract; bottom number is when ventricles relax
ventricular diastole
occurs when the ventricles relax and the atria contract; AV valves open; both semilunar valves close; makes a dupp sound
ventricular systole
occurs when ventricles contract while the atria relax; semilunar valves open; both AV valves close; makes a lubb sound
located in both right and left ventricles, chordae tendineae attach to them to reinforce atrioventricular valves and prevent prolapse.
papillary muscles
help direct the flow of blood; located in both auricles and the right atrium
pectinate muscles
name the valves
pulmonary semilunar valve; aortic semilunar valve; left atrioventicular valve; right atrioventricular valve
tricuspid valve is also known as...
right atrioventricular valve
What is the function of the valves?
they passively enforce one way blood flow and they only open of close due to blood pushing against them; made of WFCT
are ridges that slow blood flow and decrease splashing; located in both ventricles
trabeculae carneae
right atrioventricular valve is also know as...
tricuspid valve

ventricular diastole
occurs when ventricles contract while the atria relax; semilunar valves open; both AV valves close; makes a lubb sound
