Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.
<h3>How is GFR regulated?</h3>
- The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
- GFR is the sum total of filtration rates of all the working nephrons in the kidney.
- Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
- In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
- Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
- Alpha receptors are more abundant on afferent arterioles.
- This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
- This decreases blood flow to glomerulus, leading to decrease in GFR.

<span>The wings on
the beetles are examples of vestigiality. Vestigiality is a structure with
attributes that have apparently loss its ancestral function but stil present
during evolution. It is a normal evolutionary process in the changing
environment that does not pressure them to evolve.</span>
Answer:
common ancestor
Explanation:
If it is a cladogram or phylogenic tree which is what it sounds like your describing, the connection is that all organisms share a common ancestor :)
Fermentation is glycolysis on a cycle, and is done repeatedly with no oxygen. Cellular respiration has three station and requires oxygen.
