Question
ID: ame: 63. opening of the semilunar valves is called The period between the filling of the ventricles and the a. b. c. d. atrial systole. isovolumetric ventricular contraction. isovolumetric ventricular relaxation. passive ventricular filling. 64. The period during which bl ood is pumped out of the atria and into the ventricles is called: a. atrial systole. b. isovolumetric ventricular contraction. d. passive ventricular filling. shock 65. Circulatory shock caused by an acute allergic reaction is called a. cardiogenic b. hypovolemic c. anaphylactic d. septic When trying to stop arterial bleeding by applying pressure, why is it necessary to apply pressure between the bleeding part and the heart? a. Because blood flows from the heart through the arteries to the injured part 66. pressure placed between the heart and the bleeding point cuts off the source of blood flow to that point. b. Because blood pressure is greater in the arteries coming from the heart, pressure placed between the heart and bleeding point reduces pressure, thus cutting off the source of blood flow to that point Because venous blood pressure changes by alternate contraction and relaxation of c. the atria, pressure placed between the heart and bleeding point cuts off the source of venous blood flow to that point d. Because arterial blood pressure changes by alternate contraction and relaxation of the atria, pressure placed between the heart and bleeding point cuts off the source of arterial blood flow to that point. The main difference between the composition of lymph and interstitial fluid and the composition s of plasma is the percentage ofin lymph and interstitial fluid. a. lower, proteins b. higher; proteins c. lower, fats d. higher, fats All of the following are functions of the lymphatic system except: a. transporting interstitial fluid back to the bloodstream. b. providing immunological defenses. c transporting absorbed fats from the intestine to the blood. d. filtering metabolic wastes 68.Explanation / Answer
63. C. Isovolumetric ventricular relaxation.
Isovolumetric ventricular relaxation is the time interval in the cardiac cycle where the blood flows from atria to ventricles.
In this period, closure of aortic valve, to onset of filling by opening of the mitral valve occurs.
64. Isovolumetric ventricular relaxation
As mentioned in above question it is the period during which blood flows from atria to ventricles.
Passive ventricular filling is the period where blood flows from atria to ventricles when the atrioventricular valves are closed.
65. C. Anaphylactic shock
The circulatory shock caused by acute allergic reaction is called as anaphylactic shock.
It is a life threating condition. When anaphylactic shock occurs, blood pressure suddenly drops and airways become narrow, blocking normal breathing.
This condition is dangerous and if it is not treated immediately it can result in serious complications and even be fatal.
