Question

13. All of the following cause an increase in cardiac output except: increased parasympathetic stimulus to the heart b. increased venous returm C, d. e. increased stretch of the right atrial myocardium exercise increased levels of CO2 14.Starling's law of the heart states that: a. b. c. d. cardiac output increases with increased stroke volume blood moves away from an area of higher pressure to one of lower pressure the shorter the T-P interval the faster the heart rate ventricles are larger than atria increased stretch of cardiac muscle will result in greater contractile force 15. Which of the following is associated with the left ventricle? a. pectinate muscles b pulmonary veins c. fossa ovalis d. coronary sinus e. trabeculae carnii 16 weak spot in an arnerial wall causing a dilation in the wall is known as: a. arteriosclerosis b. anastomosis c, atherosclerosis d. aneurysm aphorism i.Velocity of blood flow is slowest in the: a. aorta b. arteries c. arterioles d capillaries veins A8. Vessels that supply blood to the walls of larger vessels are called: a. metarterioles b. portal veins c. vasa vasorum d sinusoids c. anastomes

Explanation / Answer

13) a

Parasympathetic stimulation decreases heart rate and force of contraction

14) e

Increased stretch of cardiac muscle will result in greater contractile force

15) b

Pulmonary veins are associated with left ventricle

16) d

Aneurysm is weakening in the aortic wall causing it to expand or balloon in size

17) d

Capillaries have slowest blood flow, which allows time for the exchange of gases and nutrients

18) c

Vasa vasorum is a network of small blood vessels that supply the walls of large blood vessels
