Study Notes
Anatomy
Body Regions
- Anterior (front) and posterior (back)
- Proximal (near the point of attachment) and distal (far from the point of attachment)
- Medial (toward the midline) and lateral (away from the midline)
- Superior (above) and inferior (below)
Body Cavities
- Cranial cavity (skull)
- Thoracic cavity (chest)
- Abdominal cavity
- Pelvic cavity
Gastrointestinal (GI) System
Gastrointestinal (GI) System
Organs
- Mouth (buccal cavity)
- Functions: mechanical and chemical digestion of food
- Esophagus
- Functions: passage of food to stomach
- Stomach
- Functions: mechanical and chemical digestion of food
- Small intestine (duodenum, jejunum, ileum)
- Functions: absorption of nutrients
- Large intestine (colon, rectum, anus)
- Functions: absorption of water, electrolytes, and vitamins; elimination of waste
GI Tract Directions
- Oral (mouth) -> abdominal (stomach) -> intestinal (small and large)
Suffixes
- -itis: inflammation (e.g., gastritis - inflammation of the stomach)
- -oma: tumor (e.g., carcinoma - cancerous tumor)
- -algia: pain (e.g., gastralgia - stomach pain)
- -ectomy: surgical removal (e.g., gastrectomy - removal of the stomach)
Anatomy
Body Regions
- Anterior refers to the front of the body
- Posterior refers to the back of the body
- Proximal refers to a location near the point of attachment
- Distal refers to a location far from the point of attachment
- Medial refers to a location toward the midline of the body
- Lateral refers to a location away from the midline of the body
- Superior refers to a location above
- Inferior refers to a location below
Body Cavities
- The cranial cavity is located in the skull
- The thoracic cavity is located in the chest
- The abdominal cavity is located in the abdominal region
- The pelvic cavity is located in the pelvic region
Gastrointestinal (GI) System
Organs of the GI System
- The mouth (buccal cavity) is responsible for mechanical and chemical digestion of food
- The esophagus enables the passage of food to the stomach
- The stomach performs mechanical and chemical digestion of food
- The small intestine (duodenum, jejunum, ileum) is responsible for absorption of nutrients
- The large intestine (colon, rectum, anus) is responsible for absorption of water, electrolytes, and vitamins, as well as elimination of waste
Directions of the GI Tract
- The direction of the GI tract is from the oral (mouth) to the abdominal (stomach) and then to the intestinal (small and large)
Suffixes in GI System Terminology
- The suffix -itis indicates inflammation
- The suffix -oma indicates a tumor
- The suffix -algia indicates pain
- The suffix -ectomy indicates surgical removal
