Nitrogenous Wastes
Excretory Systems and the Nephron
Kidney Function
Water and Salt Balance
100

These are the three main organs associated with the excretory system.

What are the skin, lungs, and kidneys?

100

This organ converts toxic ammonia into urea so it can be safely excreted.

what is the liver?

100

The functional units of the kidney, where blood filtration and urine formation occur.

What are nephrons?

100

This hormone is stimulated by the pituitary gland and  increases water reabsorption in the kidneys and reduces urine volume.

What is antidiuretic hormone (ADH)?

100

This process describes the body’s ability to keep water and salt levels stable.

What is osmoregulation?

200

These two substances are almost always 100% reabsorbed in the proximal convoluted tubule (PCT)

What is Glucose and Amino Acids?
200

We convert ammonia to this less toxic compound for excretion.

What is urea?

200

This part of the nephron is where the majority of reabsorption happens

What is the proximal convoluted tubules?

200

The part of the nephron where passive (osmosis) and active transport occurs on either side. 

What is the loop of Henle?

200

When you are dehydrated, your kidneys conserve water by producing urine with this type of colour.

what is concentrated (or darker) urine?

300

This test involves the physical, chemical, and microscopic examination of urine.

What is urinalysis?

300

Many birds excrete this nitrogenous waste as a white paste to conserve water.

What is uric acid?

300

This process in the nephron involves the transfer of substances from the blood into the filtrate to be excreted.

 What is secretion?

300

This organ is the reason why one of your kidneys are slighter larger and sits above the other.

What is the liver?

300

Caffeine and alcohol will cause this kind of change to the volume of urine.

What is increased levels?

400

This step of urine formation encompasses the direction of movement FROM the nephron (PCT, Loop of Henle, DCT, & collecting duct) BACK into the blood (capillaries).

What is reabsorption?

400

This toxic waste product is created when the body breaks down proteins

Ammonia

400

The initial step in the excretory process, where blood pressure forces fluid from the blood in the glomerulus into the Bowman’s capsule.

What is filtration?

400

The final part of the nephron that adjusts the concentration of urine before it enters the collecting duct.

What is the distal tubule?

400

This high osmolality of the interstitial fluid around the loop of Henle causes water to move out of the nephron by osmosis.

What is hypertonic?

500

This is the name of the diagnosis where the kidneys have been damaged and unable to have proper filtration for a span of 3 months or more.

What is chronic kidney disease?

500

We convert ammonia to this less toxic compound for excretion.

What is Urea?

500

This structure carries urine from the kidneys to the urinary bladder.

 What is the ureter?

500

This hormone is released by the adrenal glands when blood pressure or sodium levels drop 

What is aldosterone?

500

This part of the nephron fine-tunes any last adjustments of urine concentration by responding to osmotic gradients and hormonal signals to adjust exactly how much water is reclaimed before being excreted.

What is the collecting duct?
