1. FQ: What are the basic structures of the Urinary System (excretory)?
Today we are going to cover basic function and anatomy of the urinary system

2. Function Removal of liquid waste from the blood in the form of urine
Keep a stable balance of salts and other substances in the blood
Produce erythropoietin, a hormone that aids the formation of red blood cells.

3. Basic parts of the System

4. Kidneys – An organ that filters blood
Kidneys – An organ that filters blood. The functional unit of the kidney is the nephron

5. The Kidney
Take out your coloring sheets for reference

9. How does it work? Basically…
Blood flows to the kidney via the renal artery
It goes into the Glomerulus where waste filters across the membrane into the bowman’s capsule space
This filtrate then travels down the proximal (closest to the capsule) tubule and gets filtered some more
Filtrate travels down the loop of henle and gets filtered some more
Urea travels through the distal tubule and to the collecting duct

10. Review of the kidney

12. The Case of the Crying Baby
