Study Notes
Digestion and Related Processes
- Digestion: Breakdown of food into smaller organic fragments for nutrient absorption.
- Absorption: Simple molecules pass through cell membranes into the blood or lymphatic system.
- Ingestion: The process of taking food, drugs, or liquids into the body via the mouth.
- Elimination: Removal of waste products from the body.
Jaundice
- Characterized by yellowing of the skin due to excess bilirubin.
Gastrointestinal (GI) Tract
- Major components include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.
Esophagus
- Functions through peristalsis: alternating waves of contraction and relaxation to move food to the stomach.
Stomach
- Mixes food with gastric juices to form chyme.

Anatomy of the Digestive System
- Ascending colon connects the cecum to the transverse colon.
- Appendix is a small, tube-like structure attached to the cecum; function is debated but may have a role in gut health.
- Descending colon carries waste down to the sigmoid colon, leading to the rectum.
- Gallbladder stores and concentrates bile for fat digestion.
- Liver produces bile, processes nutrients, and detoxifies blood; key in metabolism.
- Rectum stores feces until elimination occurs.
- Stomach is a muscular organ that breaks down food using acids and enzymes.
- Spleen filters blood, recycles iron, and helps fight infection.
- Transverse colon connects the ascending and descending colons.
Diagnostic Tests for GI System
- Fecal analysis checks for presence of blood or abnormal substances in stool.
- Occult blood test detects hidden blood in stool samples.
- Culture tests for bacteria or pathogens in gastrointestinal samples.
Liver Function Tests
- ALT is an enzyme produced by the liver; elevated levels indicate liver damage.
- Serum Albumin is a protein; decreased levels suggest liver disease, kidney disease, or malnutrition.
- Bilirubin is a byproduct of red blood cell destruction; elevated levels indicate RBC destruction, liver damage, or gallbladder obstruction.
Nutritional Fundamentals
- Nutrients are classified generally into macronutrients (carbohydrates, proteins, fats) and micronutrients (vitamins, minerals).
- Vitamins serve various functions including enzyme co-factors and antioxidant roles; deficiencies can lead to specific health issues.
- Fat-soluble vitamins include A, D, E, and K; these are stored in the body's fatty tissues.

- Chronic infection with H. Pylori bacteria can lead to gastritis, increasing stomach cancer risk.
Symptoms and Signs (S&S)
-
Early Symptoms:
- Symptoms can be vague and non-specific, making early detection challenging.
- Early satiety: Feeling full after eating only a small amount.
- Anorexia: Loss of appetite.
- Indigestion: Discomfort or pain in the upper abdomen.
- Ulcer-like pain: Pain resembling peptic ulcers.
