Answer #1

1. Factors that affect heart rate are

  • Autonomic innervation
  • Hormones
  • Fitness levels
  • Age

2. Erythropoietin is the hormone that stimulates production of red blood cells and kidney secretes this hormone. Erythropoietin is produced and released into the blood by the kidneys in response to low blood oxygen levels (hypoxemia). An absence of enough oxygen in the tissues to sustain bodily functions is called as hypoxia. Thromboprotein stimulates platelet production.

1. Why is the return of venous blood to the heart impaired when heart rate is very high? inotropy (contractility) is too low (i.e., heart is not contracting hard/fast enough) dromotropy is too low (i.e., conduction speed in cardiac conduction system is slow) lusitropy is too low (i.e., heart is not spending enough time relaxing) chronotropy is too low (i.e., heart rate is too slow) 2. If afterload is high, what happens to end-systolic volume (ESV)? ESV is decreased ESV...
