| which types of papillae on the tongue contain taste buds? | -foliate – fungiform – circumvallate |
| list the three unique features of the large intestine. | – tenia coli – haustra – epiploic appendages |
What is the name of the peritoneal membranes that holds the digestive tract in place?
The sheets of the peritoneal membrane that hold the digestive tract in place are called A. mesenteries. The mesentery has several functions in the abdomen, including suspending and anchoring the small and large intestine in place and still allows for slight movements.
What material is transported in the sinusoids of the liver?

|---|---|
| Term What material is transported in the sinusoids of the liver? | Definition Mixed arterial and venous blood |
| Term Which is not a function of the digestive system? | Definition Micturition |
What holds the GI tract in place?
The digestive organs within the abdominal cavity are held in place by the peritoneum, a broad serous membranous sac made up of squamous epithelial tissue surrounded by connective tissue.
Which layer of the digestive tract contains effectors for digestive propulsion?
Which layer of the digestive tract contains the effectors for digestive propulsion? The smooth muscles in the muscularis work to make the propulsive movements called peristalsis.
What are peristaltic waves quizlet?
Peristalsis consists of waves of muscular contractions that move a bolus (small mass of food along the length of the digestive tract.) During the peristaltic waves, circular muscles contract behind the digestive contents.
Which organ contains villi?
(d) Large intestine. The lining of the small intestine contains villi – finger like projections.
What is a sinusoid in liver?
Sinusoids are low pressure vascular channels that receive blood from terminal branches of the hepatic artery and portal vein at the periphery of lobules and deliver it into central veins. Sinusoids are lined with endothelial cells and flanked by plates of hepatocytes.
What is a sinusoid in anatomy?
sinusoid, irregular tubular space for the passage of blood, taking the place of capillaries and venules in the liver, spleen, and bone marrow. The walls of the sinusoids are lined with phagocytic cells, called Kupffer cells, that digest old red blood cells and clear the bloodstream of toxins.
What is the GI tract lined with?
The mucosa, or mucous membrane layer, is the innermost tunic of the wall. It lines the lumen of the digestive tract. The mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.
Which layer of the stomach contains the gastric pits?
Which layer of the stomach contains the gastric pits that secrete mucous, acid, and digestive enzymes? The mucosa of the stomach contains the epithelial lining and the gastric pits, which extend down into the mucosa but do not penetrate the submucosa.
Which change occurs in the digestive system with aging?
Our digestive system moves food through our bodies through a series of muscle contractions. As we age, this process can slow down. When that happens, more water from the food is absorbed into the body, which can lead to constipation. Staying hydrated is very important to help prevent constipation.
