Students Will Review:
This chapter helps students review the concepts in a digestive and excretory systems unit of a standard human physiology course. Topics covered include:
- Upper and lower gastrointestinal tracts
- Functions of the excretory system
- Anatomy of the urinary system
- Structure and divisions of the kidneys
1. Digestive System I: The Upper Gastrointestinal Tract
Did you know that there are digestive enzymes in your saliva? It's true. As soon as you put a piece of food in your mouth, the digestive process begins. Join us with this first of two lessons about the human digestive system, where we'll follow food through the upper gastrointestinal tract from the mouth through the stomach.
2. Digestive System II: The Lower Gastrointestinal Tract
The lower gastrointestinal tract is the part of the digestive system that is responsible for the last part of food digestion and the expulsion of waste from the body. In this lesson, we'll look at each part of the system and what functions each serves in the process of digestion.
3. Excretory System
Each year in the U.S., close to 400,000 people with kidney failure undergo dialysis treatment in order to remove waste, remove excess fluid and restore electrolyte balance. Kidneys, the workhorses of the excretory system, perform these same functions more effectively than any machine. In this lesson, we'll talk about how the excretory system removes toxic substances from the body.
4. Gross Anatomy of the Urinary System
Our body must detoxify and cleanse itself to thrive. That is why we depend so heavily on our liver and urinary system. In this lesson, we'll explore how toxins are filtered by our organs and how urine is formed and expelled with the nephron, bladder, ureters, and urethra.
5. The Kidney: Major Divisions & Structures
Learn about the major layers of the kidneys, like the renal cortex and renal medulla. Find out about the inner parts of the kidneys, including the renal papilla, renal pelvis, renal pyramid, and renal hilum.
