Upper Digestive Tract
These structures in the mouth work together to break food into smaller pieces during mechanical digestion?
Teeth (incisors, canines, premolars, and molars)
Which intestine is longer?
The small intestine
Does the tongue aid in chemical or mechanical digestion?
Mechanical digestion
What organ is responsible for breaking down food in the digestive system?
Stomach
This wave-like muscular movement pushes food down the esophagus.
Peristalsis
This structure houses taste buds and aids in manipulating food, in addition to assisting in both mechanical and chemical digestion?
Tongue
What is the primary site for digestion and nutrient absorption?
The small intestines
Which cavity are teeth located in?
Oral cavity
What type of digestion in the stomach involves churning and mixing food?
Mechanical digestion
This thick substance lines the stomach and protects it from acid damage.
Mucus
This structure, found at the back of the oral cavity, separates the nasal and oral passages, with the soft part playing a key role in swallowing?
Palate
Which organ absorbs water and electrolytes?
The Large Intestine
What is the liver inferior to?
Diaphragm
Which chemical substance in the stomach breaks down proteins, carbs, and fats?
Enzymes
This vestigial structure of the large intestine has no essential digestive function but may play a role in immune response.
Appendix
This pharyngeal division, located below the oropharynx, is responsible for directing food to the esophagus and plays a role in both respiratory and digestive processes?
Laryngopharynx
What are the 3 parts of the small intestine?
Duodenum, Jejunum, and ileum
Which accessory organ is 8-10cm long?
Gallbladder
What two curvatures define the shape of the stomach?
Lesser Curvature and Greater Curvature
Nutrients absorbed in the small intestine are transported to the liver through this major blood vessel.
Hepatic portal vein
The esophagus is lined with this type of epithelium, which provides protection against mechanical stress during the swallowing process?
Non-keratinized stratified squamous epithelium
Label the colons displayed in the picture?
Ascending colon, transverse colon, descending colon, sigmoid colon
Name all the accessory organs
Teeth, tongue, salivary glands, liver, gallbladder, and pancreas
Which layer of the stomach protects the lining from acid and urine?
Muscosa
Parietal cells in the stomach secrete this essential substance, required for vitamin B12 absorption in the small intestine.
Intrinsic factor
