SUMMARY

The discussion centers on the concentration of proteins in post-glomerular blood compared to venous blood within the excretory system. It is established that post-glomerular blood, which is blood filtered by the glomerulus, retains a higher protein concentration due to its passage through a secondary capillary bed before rejoining the venous system. This secondary capillary bed facilitates additional water absorption, leading to a decrease in protein concentration in the venous blood. The analysis emphasizes the importance of understanding the filtration and absorption processes in the kidneys.

PREREQUISITES
  • Understanding of the excretory system and kidney functions
  • Knowledge of glomerular filtration and reabsorption processes
  • Familiarity with blood composition and concentration gradients
  • Basic concepts of capillary exchange and fluid dynamics
NEXT STEPS
  • Research the role of the nephron in kidney function
  • Study the mechanisms of glomerular filtration and tubular reabsorption
  • Explore the significance of protein concentration in blood and its physiological implications
  • Learn about the effects of dehydration on kidney function and blood composition
USEFUL FOR

Students studying biology, particularly those focusing on human anatomy and physiology, as well as educators teaching the excretory system and kidney functions.

We are learning the excretory system, and are given a thinking assignment. Okay so we are given a bunch of values for concentration of the substances in the kidney. Basically the post-glomular blood (blood after being filtered by glomerulus) has a little more protien concentration than the venous blood (blood after being reconnected to the vein system in the kidney). Why is that?

You have to show your own thinking on this problem before we can help. Also, unless you provide us with all the information you're given for the problem, we won't be able to help you much at all.
 
Okay I handed in the assignment already, I THINK I figured it out... here's what I put...

Basically I said the post glomerular blood goes through a second capilllary bed before it connects to the vein system. In that capillary bed there might have been some more water absorbed therefore the protien concentration decreases in the venous blood.

But I am probably wrong X_X...
