2. List the functions of the hormones/enzyme listed below: â€¢Aldosterone â€¢ Renin â€¢ Antidiuretic Hormone (ADH)
3. Heart failure is when the heart cannot eject enough blood tomeet the bodyâ€™s oxygen and blood demand. Describe what would be theexpected response from the RAAS (renin-angiotensin-aldosteronesystem) system in a patient with heart failure.
4. How is RAAS upregulation detrimental to heart failurepatients over time?

1 Cardiac output Heart rate X stroke volume Also Blood pressure Cardiac output x systemic vascular resistance Cardiac output decides Systolic blood pressure and systemic vacular resistance Diastolic blood pressure 2Changes in blood volume affect arterial pressure by changing cardiac output 3An increase in blood volume increases central venous pressure This increases right atrial pressure right ventricular enddiastolic pressure and volume 4This increase in ventricular preload increases ventricular stroke volume by the FrankStarling mechanism 5Frank starling law states to that force of contraction of muscle is directly proportional to the stretching of Muscles fibres by See Answer
