The Excretory System - This multi-day, 40 slide Senior Biology PowerPoint Lesson package looks at the maintenance of water balance inside mammals (specifically humans). Structurally it examines the kidney, the bladder, the components of the nephron, the collecting ducts, the minor and major calyx, the renal pelvis and the ureter. Functionally it looks at the formation of urine including: reabsorption and secretion inside the proximal tubule, loop of henle, distal tubule and collecting duct. Lastly the lesson examines the role of ADH, the importance of blood pressure and pH balance as well as kidney disease. It is a complete lesson/mini unit on the excretory system geared towards a senior level biology and/or an AP biology classroom. The PowerPoint contains many diagrams, explanations and videos. It includes the lesson (student and teacher versions of the Power Point), 6 embedded videos and a student lesson handout as a word document which follows the PowerPoint.
Included in the lesson package is:
- The teacher version of the PowerPoint

Within my Homeostasis Unit you can also find the following lessons
Lesson 1 - Homeostasis - maintaining balance
Lesson 2 - Thermoregulation - maintenance of internal body temperature
Lesson 3 - The Excretory System - maintaining water balance
Lesson 4 - The Endocrine System - chemical control system
Lesson 5 - The Nervous System
Lesson 6 - The Reproductive System
The student version of the PowerPoint contains multiple blanks that need to be filled in throughout the lesson. These blanks are conveniently underlined and bolded on the teacher copy. I have found this to be the most effective means of keeping my students engaged and active without having them write everything out. This also leaves more time for discussion and activities.
