2. The vasa recta is a specialized capillary that branches from the ___________ arteriole. The blood flow in the vasa recta runs
lorasvet [3.4K]
<h2>Vasa recta </h2>

Explanation:

The vasa recta is a specialized capillary that branches from the efferent arteriole; The blood flow in the vasa recta runs parallel, but in the opposite direction to the flow of tubular filtrate within the nephron loop

  • The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle
  • The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption
  • Absorbed water is returned to the circulatory system via the vasa recta, which surrounds the tips of the loops of Henle
  • Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla; this passive process is known as counter-current exchange

What is natural selection (not from google) give an example of what natural selection is
ruslelena [56]
Natural selection is nature’s way of keeping the best fit-to-live things alive, and so on continue to the next generations.

For example, if a rabbit has a limp, it is bound to be out run and eaten by a predator relatively early in its life (unless it is extremely lucky.) Because of this, it is unable to reproduce, and there genes that it contained to have its limp are unable to spread through inheritance. Natural selection goes both ways. For example, if a hawk has very god vision, it will be able to scope out its prey easily, so it will thrive. Therefore, when it produces offspring of its own, its trait of good eyesight will pass on to its offspring.

So, as enough time goes on, the bad traits will be weeded out and the good ones will remain.
