What prevents the atrioventricular valves from inverting into the atrium against the pressure of blood from the ventricles?Multiple choice question.chordae tendineae and papillary musclesthe shape of the valvesblood pressure in the atria

What is the function of the chordae tendineae and the papillary muscles?Multiple choice question.to pump blood from the ventricles into the arteries leaving the heartto increase surface area for the absorption of oxygen and nutrients from the blood into the heart wallto open the AV valves when the pressure of the blood in the atria is great enoughto prevent the AV valves from inverting into the atria due to the pressure of blood

Papillary musclesMultiple Choiceare attached to the semilunar valves via the chordae tendineae.prevent the backflow of blood into the atria during ventricular systole.prevent the backflow of blood into the ventricles from the aorta.prevent the valves from closing during ventricular diastole.contract when the ventricles relax.

When the atria are contracting you would expect:Question 2Select one or more:a.The atrioventricular valves to be open.b.Pressure in the atria to be higher than the pressure in the ventricles.c.The semilunar valves to be open.d.Blood to be moving from ventricles to atria.e.The ventricles to be in diastole.

Which statement is true of the right atrioventricular valve? it is also called the mitral valve it is open during ventricular diastole it transmits oxygenated blood it is opened by the pull of chordae tendineae it consists of 2 leaflets

What is the function of chordae tendineae?Multiple ChoiceGenerate force to push blood through the heartOpen the AV valves during atrial contractionCarry electrical signals through the ventricular myocardiumPrevent the cusps of the AV valves from moving up into the atria
