True False D Question 16 During the period of ventricular filing opressure in the heart is at its peak o blood flows passively through the atria and the open AV valves into the ventides o the atria remain in diastole o i is represented by the P wave on the ECG D Question 17 which of the following is greate? o heart rate when norepinephrine is released on the S-A node heart rate when acetylcholine is released on the S-A node Question 18 Which of the following is NOT true regarding a heart murmur? o can be heard with a stethoscope o may be caused by a stenotic valve o may be caused by an incompetent o may be caused by a bundle block Question 19Explanation / Answer
Being overweight increases the blood pressure primarily by increasing the blood vessel length.
True.
This increases the vascular resistance and it will increase the blood pressure. Other reason is that there will be more tissue mass which has to be transported with oxygen and nutrient thus more pressure will be requiired.

B. Blood flows passively through the atria,open av valve and into the ventricles.
