|---|---|---|---|---|---|
| what is osmoregulation based on? | based largely on controlled movement of solutes between internal fluids and the external environment
🗑
|
||||
| what are osmoconfromers? | they are isoomotic with their surroundings and do not regulate their osmolarity
🗑
|
||||
| what are osmoregulators? | expend energy to control water uptake and loss in a hyperosmotic or hypoosmotic environment
🗑
|
||||
| what are transport epithelia? | specialized cells that regulate solute movement
🗑
|
||||
| what do excretory systems produce? | they produce urine by refining a filtrate derived from body fluids
🗑
|
||||
| what are the functions of excretory systems? | - Filtration: pressure-filtering of body fluids
- Reabsorption: reclaiming valuable solutes
- Secretion: adding toxins and other solutes from the body fluids to the filtarte
- Excretion: removing the filtrate from the system
🗑
|
||||
| what are nephrons the functional unit of? | mammalian kidney
🗑
|
||||
| when does filtration occurs? | occurs as blood pressure forces fluid from the blood in the glomerulus into the lumen of Bowman's capsule
🗑
|
||||
| what is the pathway of the filtrate? | From bowman's capsule, the filtrate passes through three regions of the nephron: the proximal tubule, the loop of Henle, andthe distal tubule
🗑
|
||||
| when does filtrate becomes urine? | becomes urine as it flows through the mammalian nephron and collecting duct
🗑
|
||||
| how does the mammalian kidney conserve water? | conserves water by producing urine that is much more concentrated than body fluids
🗑
|
||||
| what do NaCl and urea contribute to? | contribute to the osmolarity of the interstitial fluid, which causes reabsorption of water in the kidney and concentrates the urine
🗑

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.
