rodikova [14]

A mechanism that is effective in maintaining a normal glomerular blood pressure only if the systemic mean arterial pressure remains between 80 and 180 mm hg is called renal autoregulation.

<h3>What is renal autoregulation?</h3>
  • Autoregulation is the inner characteristic of blood vessels present in end organs, like heart, kidney, and mind, by which they dilate or constrict in response to pressure changes, thus help to keep the blood flow generally steady.
  • Usually our body tries to regulate our blood pressure in range of 50 to 150 mm Hg.
  • Regulation of renal blood flow and glomerular blood pressure in kidneys is called renal autoregulation.
  • There are 3 mechanisms of renal blood flow namely myogenic response (MR), tubuloglomerular feedback (TGF) and third mechanism that is independent of TGF but slower than MR.

Which role do gametes play in reproduction?
Lesechka [4]
<span>C. Gametes are the sex cells, and each (sperm and ovum) contain half of the parent's genetic material. These cells will fuse to produce a zygote, which will usually contain the full number of genes required by an organism to live. If there is a chromosomal abnormality, such as a gamete with an extra chromosome, the offspring can either die in development or sometimes be born with physiological and/or developmental difficulties. An example of this phenomenon is trisomy 21, also known as Down Syndrome, in which the 21st chromosome bears 3 copies instead of the regular 2.</span>
