| Aldosterone from the adrenal cortex causes sodium ions to be | Conserved & potassium ions to be excreted
🗑
|
||||
| An increase in glomerular osmotic pressure ____ the rate of glomerular filtration | Decreases
🗑
|

| Filtration rate in the glomerulus is increased by | Both vasodilation of the afferent arteriole & vasoconstriction of the efferent arteriole
🗑
|
||||
| The juxtaglomerular apparatus regulates the filtration rate by | Renin-angiotensin 2 vasoconstricting both the afferent & efferent arterioles

🗑
|
||||
| The _______ ______ acts as the counter current multiplier. | Nephron loop
🗑
|
||||
| The increase in osmolarity as filtrate moves down the descending limb is due to ______ moving out of the tubule. | Water
🗑
|
||||
| The decrease in osmolarity of the filtrate as it moves up the ascending limb due to _____ moving out of the tubule. | Solutes
🗑
|
||||
| The filtrate is _______ at the tip of the nephron loop & _____ at the end of the ascending limb. | Hypertonic
Hypotonic
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
