    Study Notes

    Functions of the Digestive System

    • The digestive system has six main functions: ingestion, motility, secretion, digestion, absorption, and elimination of wastes.

    Large Intestine

    • The large intestine is the final organ of the GI tract, continuing from the small intestine and forming a border around it in the abdominopelvic cavity.
    • It absorbs most of the water from the remaining digested material and compacts undigested material and waste products into faeces, which are then defecated.
    • The large intestine consists of the caecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal.

    Intraperitoneal vs Retroperitoneal Digestive Organs

    • Organs that are completely surrounded by visceral peritoneum are referred to as intraperitoneal.
    • Organs that are only covered by parietal peritoneum on their anterior surfaces are referred to as retroperitoneal.
    • The mnemonic "SAD PUCKER" can be used to remember the retroperitoneal organs.

    Salivary Glands

    • The salivary glands can be classified as either major or minor salivary glands.
    • There are three pairs of major salivary glands: the parotid, submandibular, and sublingual glands.
    • Saliva dissolves the molecules in ingested material, lubricates the oral cavity, and has antibacterial properties that help maintain oral hygiene.

    Abdominopelvic Quadrants, Peritoneal Relationship, and Primitive Gut Tube Origin

    • The abdominopelvic cavity can be divided into quadrants.
    • Digestive organs can be classified based on their peritoneal relationships and primitive gut tube origins.

    Liver

    • The liver is the largest gland in the body.
    • It is an intraperitoneal organ located primarily in the right upper quadrant of the abdominopelvic cavity, extending into the left upper quadrant.
    • The liver has a small area called the bare area that is not covered by peritoneum.

    Peritoneum

    • The peritoneum is a serous membrane lining the abdominopelvic cavity.
    • It has an outer parietal layer lining the internal surface of the body cavity and an inner visceral layer lining the external surface of some of the organs in the cavity.
    • The peritoneum has a potential space in between its layers, which is called the peritoneal cavity and contains a thin film of fluid called serous fluid.

    Functions of the Digestive System

    • The digestive system has six main functions: ingestion, motility, secretion, digestion, absorption, and elimination of wastes.

    Large Intestine

    • The large intestine is the final organ of the GI tract, continuing from the small intestine and forming a border around it in the abdominopelvic cavity.
    • It absorbs most of the water from the remaining digested material and compacts undigested material and waste products into faeces, which are then defecated.
    • The large intestine consists of the caecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal.

    Intraperitoneal vs Retroperitoneal Digestive Organs

    • Organs that are completely surrounded by visceral peritoneum are referred to as intraperitoneal.
    • Organs that are only covered by parietal peritoneum on their anterior surfaces are referred to as retroperitoneal.
    • The mnemonic "SAD PUCKER" can be used to remember the retroperitoneal organs.

    Salivary Glands

    • The salivary glands can be classified as either major or minor salivary glands.
    • There are three pairs of major salivary glands: the parotid, submandibular, and sublingual glands.
    • Saliva dissolves the molecules in ingested material, lubricates the oral cavity, and has antibacterial properties that help maintain oral hygiene.

    Abdominopelvic Quadrants, Peritoneal Relationship, and Primitive Gut Tube Origin

    • The abdominopelvic cavity can be divided into quadrants.
    • Digestive organs can be classified based on their peritoneal relationships and primitive gut tube origins.

    Liver

    • The liver is the largest gland in the body.
    • It is an intraperitoneal organ located primarily in the right upper quadrant of the abdominopelvic cavity, extending into the left upper quadrant.
    • The liver has a small area called the bare area that is not covered by peritoneum.

    Peritoneum

    • The peritoneum is a serous membrane lining the abdominopelvic cavity.
    • It has an outer parietal layer lining the internal surface of the body cavity and an inner visceral layer lining the external surface of some of the organs in the cavity.
    • The peritoneum has a potential space in between its layers, which is called the peritoneal cavity and contains a thin film of fluid called serous fluid.

    Functions of the Digestive System

    • The digestive system has six main functions: ingestion, motility, secretion, digestion, absorption, and elimination of wastes.

    Digestive System Anatomy

    • The large intestine is the final organ of the GI tract, continuing from the small intestine and forming a border around it in the abdominopelvic cavity.
    • It absorbs most water from remaining digested material and compacts undigested material and waste products into faeces, which are then defecated.
    • The large intestine consists of the caecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal.

    Intraperitoneal vs Retroperitoneal Digestive Organs

    • Organs completely surrounded by visceral peritoneum are referred to as intraperitoneal.
    • Organs only covered by parietal peritoneum on their anterior surfaces are referred to as retroperitoneal.

    Salivary Glands

    • Saliva dissolves molecules in ingested material, allowing for the stimulation of taste buds on the tongue.
    • Saliva lubricates the oral cavity and has antibacterial properties that help maintain oral hygiene.
    • There are three pairs of major salivary glands: parotid, submandibular, and sublingual glands.

    Abdominopelvic Quadrants and Peritoneal Relationship

    • The liver, gallbladder, and pancreas are located in the abdominopelvic cavity.
    • Each of these organs can be classified as either intraperitoneal or retroperitoneal, and the part of the primitive gut tube they are derived from can be identified.

    Liver

    • The liver is an intraperitoneal organ located primarily in the right upper quadrant of the abdominopelvic cavity, extending into the left upper quadrant.
    • The liver is the largest gland in the body, sitting just underneath the diaphragm.
    • Only a small area of the liver, the bare area, is not covered by peritoneum.
