Digestive System Anatomy Flashcards
Accessory Organ
Includes liver, gallbladder, pancreas, teeth, and salivary glands
Alimentary Canal
- Mouth
- Pharynx
- Esophagus
- Stomach
- Small intestine (Duodenum, jejunum, ileum)
- Ileocecal valve
- Large intestine (colon)
- Anus
Anus
- Located at the end of the large intestine.
- The anus consists of a muscular ring and flat cells that line the inside of the anus.
Cecum
Comma-shaped pouch, which is the first part of the large intestine.
Common Bile Duct
A relatively long and winding tube found within the lesser omentum.
Cystic Duct
Connects the gallbladder to the common bile duct.
Epiglottis
Shaped like an isosceles triangle and located behind the tongue, in front of the soft palate.
Esophagus
The esophagus runs along the dorsal side of the trachea in the neck and chest.
Gallbladder
Located under the liver.
Hard Palate
The bony, front part of the roof of the cat’s mouth.
Hepatic Duct
Located in the liver.
Large Intestine (colon)
Located in the abdominal cavity.
Liver
Located in the abdominal cavity, between the diaphragm and the stomach.
Mesentery
- A fan-shaped structure in the mid-abdomen that connects the small intestine to the back of the body and provides support.
Mouth
The lower front part of the face, is located between the upper and lower jaws.
Omentum (greater & lesser)
- [Greater] A large, apron-like tissue fold that hangs from the stomach and covers the abdomen.
- [Lesser] Connects the stomach, duodenum, and liver.
Pancreas
V-shaped and located on the right side of the abdomen near the duodenum.
Parietal Peritoneum
Covers abdominal wall, diaphragm, and pelvic walls.
Pharynx
Located at the back of the mouth and throat, it connects the nasal and oral cavities to the esophagus and trachea.
Pyloric Sphincter
A muscular ring located at the narrow end of the stomach where it connects to the duodenum.
Rectum
Final few inches of the large intestine and connects to the anus.
Rugae
Are folds in the stomach and hard palate
Salivary Gland
On the face, behind the corners of the lips, and extending from under the eye to the lower jaw.
Small Intestine (Duodenum, Jejunum, Ileum)
A tubular organ in the abdominal cavity that connects the stomach to the large intestine.
Soft Palate
A flexible, triangular tissue that stretches from the hard palate to the pharynx.
Stomach
C-shaped, primarily on the left side of the abdomen and below the liver.
Uvula
A cone-shaped structure hanging from the soft palate at the back of the throat (present in humans, but not in cats).
Villi
Finger-like projections on the inner lining of the small intestine (duodenum, jejunum, and ileum) that help absorb nutrients.
