Renal Anatomy
Filtration Activity
Nephron
Dissection
Function
100

This organ is responsible for collecting and holding urine before it is transported out through the urethra.

 What is the urinary bladder?

100

To prepare the filtration activity, this cup has filtrate (water and beads) in it.

What is the “renal artery” cup?

100

This microscopic structure in the kidney is where actual work of filtration takes place.

What are nephrons?

100

The name of the protective outer layer of the kidney.

What is the capsule?

100

The primary function of the kidneys.

How does it filter waste from blood?

200

This structure contains the loop of Henle along with the columns and pyramids.

What is the renal medulla?

200

The different spoons represent this structure.

What are transport proteins?

200

This part of the nephron is responsible for water reabsorption.

What is the Loop of Henle?

200

When examining tubes attached to kidney, this tube is small and round.

What is the renal artery?

200

When the kidneys sense low oxygen, blood pressure, or calcium they respond by releasing these. 

What are hormones?

300

This structure is at the apex of the renal pyramid and directs urine to the minor calyx.

What is the renal papilla?

300

If a group is unable to transfer all of the small blue beads, they are said to have this condition.

What is diabetes/glucosuria?

300

Filtration begins in this outer region.

What is the cortex?

300

When examining the tubes of the kidney, this tube is flat.

What is the renal vein?

300

Dehydration can cause this.

What is a build-up of wastes and acids that could lead to kidney stones and urinary tract infections?

400

This structure is a pathway for blood vessels and structural integrity.

What are the renal columns?

400

The process of the filter blocking large beads then being transported into the “renal artery” cup.

What is glomerular filtration?

400

This process is the first step in forming urine.

What is glomerular filtration?

400

This visible, white area in the middle is the final central collection area that connects to the ureter. 

What is the renal pelvis?

400

The purpose of filtration.

How to remove waste/extra fluid, maintain a balance of water, salts, and minerals in your blood?

500

Name all structures in order of filtration.

What is the 

Capsule
Renal artery
Renal vein
Cortex
Nephron
Medulla
Renal columns
renal pyramids
Minor calyx
Major calyx
Renal pelvis
Ureter

500

The process of moving small beads back into the “renal vein” cup represents this physiological process.

What is tubular reabsorption?

500

This process moves waste products (excess ions or toxins) from blood into renal tubules to be excreted in urine.

What is tubular secretion?

500

These specific items are needed to pack for a kidney dissection successfully.

What are forceps, scalpels, filtration activity, plates, sheep kidneys, and paper towels?

500

Define osmolarity.

What is the total concentration of all solute particles in a solution?

Osmosis: A chemical process allows kidney to reabsorb water and concentrate urine. 

Explanation: Kidneys manage water balance by concentrating/diluting ruing --> maintains fluid balance.
