Which of the following are mechanisms of intrinsic control of glomerular filtration (renal autoregulation)?sympathetic nervous system control and the renin-angiotensin mechanismtubuloglomerular feedback and the renin-angiotensin mechanismmyogenic mechanism and tubuloglomerular feedbackmyogenic mechanism and sympathetic nervous system control
  • eliminates solid, undigested wastes and excretes carbon dioxide, water, salts, and heat
  • renin-angiotensin mechanism
  • the volume of filtrate created by the kidneys per minute
  • myogenic mechanism and tubuloglomerular feedbackBoth of these mechanisms occur strictly within kidney (i.e., intrinsic controls). The myogenic mechanism is mediated by smooth muscle within the afferent arteriole. In contrast, tubuloglomerular feedback is mediated by macula densa cells of the juxtaglomerular apparatus (JGA).
