1Angiotensin One has which one of the following effects on blood vessels?

- BReduces permeability
- CIncreases permeability
- DAngiotensin one is an inactive precursor chemical
- EProduces vasodilatation
2Papillary muscles serve which one of the following functions in the heart?
- ADirect blood flow towards the out flow tract during systole

- CRight coronary artery
- DLeft main coronary artery
- EThe coronary sinus
6Which one of the following best describes the coronary ostia?
- AIs the physiological narrowing in the coronary vessel that ensures a low pressure distal to the ostia so that coronary flow is maintained
- BThe coronary ostia is the opening to the right atrium off the vena cava
- CIt is the opening in the aorta which supplies oxygenated blood to the coronary vessels
- DIt is the point in the coronary circulation where the left coronary artery divides into the left anterior descending and the circumflex artery
- EIt is the connection between the arterial and venous systems in the coronary vasculature
7The aortic valve is designed to prevent flow of blood in which one of the following situations?
- AFrom the right atrium into the vena cava during diastole
- BThe from the left ventricle into the left atrium during systole
- CFrom the right atrium into the vena cava during systole
- DFrom the aorta into the left ventricle during diastole
- EFrom the right ventricle into the right atrium during systole
