On Fig. 5.1, add label lines and letters to identify: G - the glomerulus; L - the lumen of the Bowman’s (renal) capsule.
In ultrafiltration, blood components in the glomerulus with a relative molecular mass greater than $68000$ are stopped from entering Bowman’s capsule by a filtration barrier. Name the structure that provides this barrier.
The glomerular filtration rate (GFR) is the volume of filtered fluid moving through the kidneys each unit time. Complete Table 5.1 to show whether the GFR is normal, increased, or decreased for each pair of arteriole diameters given. The first row has already been done for you.
Once it leaves Bowman’s capsule, the glomerular filtrate enters the proximal convoluted tubule, where selective reabsorption takes place. Describe and explain how all of the glucose in the glomerular filtrate is reabsorbed back into the blood.
State and explain three features of a proximal convoluted tubule cell that make it suitable for its function.
