The closure of the mittal and tricuspid valves at the start of the ventricular systole produces the first sound 'LUBB '

True or False. If false give the correct statement: (i) In apoplastic movement the water travels through the cell membrane and enter the cell. (ii) The closure of the mitral and tricuspid valves at the start of the ventricular systole produced the first sounnd 'LUBB'.

The ______and __ valves close shortly after the start of ventricular systole..

In terms of being open or closed, what is the state of the mitral and tricuspid valves (left and right atrioventricular valves, respectively) at the end of the first heart sound?

Second heart sound-called dupp, is heard at the end of ventricular systole.

Read the following four statements (1-4) (1 ) The second heart sound is DUB, which is associated with the closure of bicuspid and tricuspid valves . (2) The duration between consecutive second and first heart sound is 0.5 second in a cardiac cycle . (3) The heartbeat of a human increase when the adrenaline hormone in injected into it. (4) The atrial systole in a cardiac cycle increase the flow of blood into the respective ventricle by about 70% . How many of the above statements are incorrect ?

Which of the following statement is CORRECT ? I. Heart, the mesodermally derived organ, is situated in the thoracic cavity, in between the two lungs , slightly tilted to the left. II. During joint diastole , tricuspid and bicuspid valves are open and the semilunar values are closed. III. The first heart sound (lub) is associated with the closure of the tricuspid and biscuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves . IV. Neural signals through the sympathetic nerves can increases the rate of hearbeat, the strength of ventricular contraction and thereby the cardiac output.
