The frank-starling mechanism is a compensatory response to heart failure that can support cardiac output but also worsen heart failure. which statements regarding this mechanism are correct? select all that apply.

• Decrease in cardiac output causes an increase in preload. 
• Diuretics reduce blood volume and myocardial oxygen demand. 
• Excessive stretch on the ventricular wall will decrease preload.

Frank-starling mechanism showing the relation of the end diastolic pressure (EDP) and the contraction power(calculated by stroke volume).

In heart failure, failure to pump the blood(decrease in cardiac output) will increase the preload/EDP. The diuretic can decrease blood volume which will reduce the amount of blood the heart has to pump. Stretching of muscle will decrease the EDP and decrease the preload as well.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

starchy vegetablesnon-starchy vegetables

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

hope this !
