12.During cardiac cycle syatole and diastole of both atria and ventricles contract and release.atria and ventricles never contact at the simultaneously.but at first both atria contract atbthe same time and then relax releasing blood to ventricles.atrial syatole lasts for 0.1 sec during which ventricles remain relaxed.
So option 1 is the correct answer.
13.Large arteries are termed as elastic arteries.medium sized arteries are called muscular arteries.arterioles are small arteries that deliver blood to capillaries.Through constriction and dilation,arterioles assume a key role in regulating blood flow from arteries into capillaries thus altering blood pressure.
Option: c
14.false.because the propagation of cardiac action potential s as follows.SA node -atrial synctium-AV node- AV bundle- bundle branches- Purkinje fibres- ventricular synctium-AV..
16.120/80 is normal blood pressure mmHg.it is the hydrostatic pressure exerted by blood on the walls.it is measured by sphygmomanometer.so120/88 is stage 1 hypertension.
