osmoregulation Flashcards
Why do renal organs eliminate nitrogenous wastes?
Renal organs eliminate nitrogenous wastes to regulate water and electrolyte levels.
What is the role of the Glomerulus?
The Glomerulus filters blood, allowing certain substances to pass through.
What happens in the convoluted tubules?
In the convoluted tubules, certain substances come out while others remain in the filtrate.
What is the function of the loop of Henle?
The loop of Henle retains water and NaCl through its countercurrent structure.
Where does urea recycling occur?
Urea recycling occurs in the nephron and is necessary for maintaining osmotic balance.
When and how are antidiuretic hormone and aquaporins used?
Antidiuretic hormone and aquaporins are employed to save water and create concentrated urine.
What is osmosis?
Osmosis is the movement of water across a semipermeable membrane.
What is osmotic pressure?
Osmotic pressure is the pressure required to prevent the flow of water across a semipermeable membrane.
What is osmoregulation?
Osmoregulation is the process of maintaining water and electrolyte balance in the body.
What are the differences between ammonia, urea, and uric acid?
Ammonia is highly toxic, urea is less toxic and requires less water for excretion, while uric acid is the least toxic and conserves water.
What are the processes involved in kidney function?
The processes involved in kidney function include filtration, reabsorption, and secretion.
What are the main parts of the nephron?
The main parts of the nephron include the renal cortex, renal medulla, glomerulus, Bowman’s capsule, and the loop of Henle.
What are podocytes?
Podocytes are specialized cells in the glomerulus that help filter blood.
What is the difference between proximal and distal convoluted tubules?
The proximal convoluted tubule reabsorbs nutrients, while the distal convoluted tubule is involved in further processing of filtrate.
What are the ascending and descending limbs of the loop of Henle?
The descending limb is permeable to water, while the ascending limb is permeable to NaCl.
