letter answers please

Answer 1

9A) E

Cardiac output is the product of stroke volume and heart rate which is CO = SV * HR. brains has the functionality of controlling the heart rate but pons is a part of the brain which controls the sensory information like bladder control, taste, hearing, respiration, swallowing, equilibrium etc.,

10A)

During ventricular systole the Semilunar (SL) valves open

11A)

Relaxation

T- WAVE                                               -   (E)VENTRICULAR REPOLARIZATION

S1 SOUND(LUBB)                             - (B)AV VALUES CLOSING

QRS                                                        - (A) Ventricular depolarization

S2 SOUND(DUPP)                            - (D) SL VALUES CLOSING

P-WAVE                                               -    (C) ATRIAL DEPOLARIZATION
