1. Unit 16: Abdominal & Thoracic Injuries
Lesson 1: Abdominal Anatomy

2. Grab binders and note taker In your bell work log…
Create a list of the ORGANS within the abdominal cavity

3. Objectives
Recognize relevant anatomy of the abdominal cavity

4. Terminology Absorption Antibodies Bile Chyme Detoxify Diaphragm
A process where digested food moves into the bloodstream to be used throughout the body
Antibodies
A type of cell produced by the spleen to defend the body against foreign cells
Bile
A substance produced by the liver that neutralizes the acid of the stomach and helps digest fat in the small intestine
Chyme
A semi-liquid substance formed when ingested food is mixed with digestive fluids from the stomach
Detoxify
The process of breaking down harmful chemicals
Diaphragm
A large muscle located between the chest and the abdomen that helps control breathing

7. The Abdominal Cavity Organs
Three organ systems reside in the abdominal cavity
Digestive System
Urinary System
Reproductive System

8. Abdominal Organs Solid Organs Hollow Organs Contain large blood supply
Injury to these are generally life threatening
Ex: Liver, Kidneys, Spleen, Pancreas
Hollow Organs
Organs that are able to bend and move
Injuries to these are less serious
Ex: Stomach, Intestines, Appendix

9. Liver Secretes bile for digestion Detoxifies harmful chemicals
Hollow or Solid?

10. Gall Bladder
Stores bile the liver used in digestion
Hollow or Solid?

11. Pancreas Produces insulin Secretes pancreatic juice for digestion
Liver
Produces insulin
Secretes pancreatic juice for digestion
Gall Bladder
Pancreas

12. Kidneys Filters blood from the rest of the body
Excretes waste products in the form of urine

13. Stomach
Food mixes with secretions to form chyme

14. Spleen Stores and regulates the number of red blood cells in the body
Produces antibodies

15. Intestines Where digestion and absorption takes place
Small Intestine
Large Intestine
Where digestion and absorption takes place
Final digestion and absorption of food occurs
Chyme is converted to feces to be expelled

16. Urinary Bladder
Stores and helps expel urine

17. Appendix Small “worm” like tube off of the large intestine
The opened end drains into the large intestine
The wall of the appendix makes a mucus that has antibodies to help the immune system

23. The left kidney is located slightly more superior than the right kidney due to the larger size of the liver on the right side of the body.

24. List the borders of the abdominal cavity
Closure
List the borders of the abdominal cavity
What 3 organ systems are located in the abdominal cavity?
What quadrant is the liver?
What quadrant is the appendix?
What quadrant is the stomach?
