UNIT 16: ABDOMINAL &THORACIC INJURIES Lesson 1: Abdominal Anatomy

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

OBJECTIVES Recognize relevant anatomy of the abdominal cavity

TERMINOLOGY Absorption � 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 � Detoxify � A semi-liquid substance formed when ingested food is mixed with digestive fluids from the stomach The process of breaking down harmful chemicals Diaphragm � A large muscle located between the chest and the abdomen that helps control breathing

THE ABDOMINAL CAVITY ORGANS Three organ systems reside in the abdominal cavity Digestive System Urinary System Reproductive System

ABDOMINAL ORGANS Solid 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

LIVER Secretes bile for digestion Detoxifies harmful chemicals Hollow or Solid?

GALL BLADDER Stores bile the liver used in digestion Hollow or Solid?

Liver PANCREAS Produces insulin Secretes pancreatic juice for digestion Gall Bladder Pancreas

KIDNEYS Filters blood from the rest of the body Excretes waste products in the form of urine

STOMACH Food mixes with secretions to form chyme

SPLEEN Stores and regulates the number of red blood cells in the body Produces antibodies

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

URINARY BLADDER Stores and helps expel urine

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

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.

CLOSURE 1. 2. 3. 4. 5. 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?
