Answer:
1.Option d is the correct answer.
Pericardium has no role to aid cardiac contraction,it is a outer covering of the heart, cardiac contraction is depends on mainly on myocardium and other parts associated with it.Pericardium is a physical barrier and prevents inflammation and infections and partly helps in maintaining heart rate and blood pressure so option a,b,c are correct only option d is incorrect
2.Option c is the correct answer.
Left ventricle is the thickest portion of the heart and in recieves huge volume of blood from left atrium and it pumps it to the whole body so it endures huge volume of blood.Hence the option c is the correct option.
3.Option b is the correct answer.
At the end of isovolumetric relaxation phase ventricular pressure becomes lower than atria so atrioventricular valve open and blood moves into ventricle.Hence option b is correct.
4.Option b is the correct answer.
Pulmonary veins are the only vein which carry oxygenated blood coming from the pulmonary circulation.Hence the option b is the correct option.
