Urinary System Day 3

Homework Addition: Find a picture/diagram that helps illustrate how the kidneys filter blood Point to the structures you are talking about Create 3 questions to ask after you present that they cannot answer from just looking at the diagram Present your info

Student Listener: Grade the Presenter: 1 bad 5 awesome explanation Give feedback: (on the bottom or back) What could they have done better?

Review from Yesterday capsule cortex Hilum ureter

Parts of the Kidney diagram & notes Renal Medulla: innermost section of the kidney Contains the pyramids medulla

Renal Pyramids: Takes urine from the cortex to the minor calyx Houses the Collecting Ducts Renal Pyramids: Minor Calyx cortex pyramid

Minor Calyx: cup-shaped opening/cavity that collects the urine and sends it to the major calyx

Major Calyx: 2 or 3 minor calyces form 1 major calyx; sends urine to the ureter
