Why the blood entering the efferent arteriole is thicker

[From: ] [author: ] [Date: 11-05-25] [Hit: ]
-If youre talking about blood flow through the glomerulus, water and solutes can cross the capillary wall and into the tubule, but red blood cells and protein (albumin) cant. Concentration of these is higher in the efferent arteriole than in the afferent arteriole because some plasma (water + solutes) has passed crossed into the tubule. The osmotic pressure is higher in the efferent arteriole than in the afferent arteriole for the same reason. If this is what you mean by thicker then you have your answer.......
Why the blood entering the efferent arteriole is thicker than the blood entering the afferent arteriole's ?

The explanation is like "as plasma has entered the tubule, but still contains oxygen that is moved on to the peritubular network to provide for the metabolic needs of the tubule."

But I still don't understand. Would any please help me out? Thank you very much.
