Study Notes
Gastrointestinal System (GIT)
- Mouth: Located in the oral cavity, head region; Anterior to the GIT. Chews (masticates), mixes food with saliva; initiates carbohydrate digestion.
- Parts: Lips, teeth, tongue, salivary glands (parotid, submandibular, sublingual).
- Blood Supply: External carotid artery.
- Venous Drainage: Facial vein, lingual vein.
- Nerve Supply: Sensory: Trigeminal nerve (CN V); Motor: Hypoglossal nerve (CN XII), facial nerve (CN VII).
Pharynx
- Location: Posterior to the oral and nasal cavities.
- Position: Connects the mouth and esophagus.
- Function: Swallowing (deglutition).
- Parts: Nasopharynx, oropharynx, laryngopharynx.
- Blood Supply: Ascending pharyngeal artery (branch of external carotid).
- Venous Drainage: Pharyngeal venous plexus.
- Nerve Supply: Glossopharyngeal nerve (CN IX), vagus nerve (CN X).
Esophagus
- Location: Thoracic cavity, posterior to the trachea.
- Position: Connects the pharynx to the stomach.
- Function: Propels food to the stomach via peristalsis.
- Parts: Cervical, thoracic, abdominal segments.
- Blood Supply: Inferior thyroid artery, esophageal branches of the aorta.
- Venous Drainage: Esophageal veins to azygos and hemiazygos veins.
- Nerve Supply: Parasympathetic: Vagus nerve (CN X).
Stomach
- Location: Upper left quadrant of the abdomen.
- Position: Intraperitoneal, between the esophagus and duodenum.
- Function: Mechanical and chemical digestion; secretes gastric juice.
- Parts: Cardia, fundus, body, pylorus.
- Blood Supply: Left gastric artery, right gastric artery, gastroepiploic arteries.
- Venous Drainage: Gastric veins to portal vein.
- Nerve Supply: Parasympathetic: Vagus (CN X); Sympathetic: Celiac plexus.
Small Intestine
- Location: Central abdomen.
- Position: Intraperitoneal, extends from the stomach to the large intestine.
- Function: Absorption of nutrients, continued digestion.
- Parts: Duodenum, jejunum, ileum.
- Blood Supply: Duodenum: Gastroduodenal and superior mesenteric arteries; Jejunum and ileum: Superior mesenteric artery.
- Venous Drainage: Superior mesenteric vein to portal vein.
- Nerve Supply: Parasympathetic: Vagus (CN X); Sympathetic: Superior mesenteric plexus.
Large Intestine
- Location: Encircles the small intestine in the abdominal cavity.
- Position: Retroperitoneal (ascending, descending colon) and intraperitoneal (transverse, sigmoid colon).
- Function: Water absorption, formation of feces.
- Parts: Cecum, appendix, colon (ascending, transverse, descending, sigmoid), rectum, anal canal.
- Blood Supply: Cecum & Appendix: Ileocolic artery; Colon: Branches of superior and inferior mesenteric arteries; Rectum: Superior rectal artery, middle rectal artery.
- Venous Drainage: Corresponding veins to portal or systemic circulation.
- Nerve Supply: Parasympathetic: Vagus nerve (up to mid-transverse colon), pelvic splanchnic nerves (distal); Sympathetic: Superior and inferior mesenteric plexuses.
Liver
- Location: Upper right quadrant, under the diaphragm.
- Position: Intraperitoneal.
- Function: Metabolism, bile production, detoxification.
- Parts: Right lobe, left lobe, quadrate lobe, caudate lobe.
- Blood Supply: Hepatic artery (from celiac trunk).
- Venous Drainage: Hepatic veins to inferior vena cava.
- Nerve Supply: Parasympathetic: Vagus nerve; Sympathetic: Celiac plexus.
Gallbladder
- Location: Inferior surface of the liver.
- Position: Intraperitoneal.
- Function: Stores and concentrates bile.
- Parts: Fundus, body, neck.
- Blood Supply: Cystic artery.
- Venous Drainage: Cystic veins to portal vein.
- Nerve Supply: Parasympathetic: Vagus nerve; Sympathetic: Celiac plexus.
Pancreas
- Location: Posterior to the stomach.
- Position: Retroperitoneal.
- Function: Produces digestive enzymes and hormones (insulin, glucagon).
- Parts: Head, body, tail.
- Blood Supply: Splenic artery, superior and inferior pancreaticoduodenal arteries.
- Venous Drainage: Pancreatic veins to portal vein.
- Nerve Supply: Parasympathetic: Vagus nerve; Sympathetic: Celiac plexus, superior mesenteric plexus.
Rectum and Anus
- Location: Pelvic cavity.
- Position: Terminal part of the GIT.
- Function: Storage and excretion of feces.
- Parts: Rectum, anal canal.
- Blood Supply: Superior, middle, inferior rectal arteries.
- Venous Drainage: Rectal veins to portal and systemic veins.
- Nerve Supply: Parasympathetic: Pelvic splanchnic nerves; Sympathetic: Hypogastric plexus.
