The peritoneum is the most extensive serous membrane in the body.

The ______________ circulation drains all of the organs of the digestive system.

Unitary smooth muscle is found in all hollow organs except for the heart. What structures do both heart muscles and unitary smooth muscle share that allows them to contract as a functional group?

Which layer of the alimentary canal contains not only glands and blood vessels but also a nerve plexus that helps regulate digestive activity?

Which layer of the alimentary canal is constructed from either stratified squamous or simple columnar epithelium?

What tissue type has polarity and is avascular?

Which of the following is NOT a manner in which any epithelial tissue is classified?

Which of the following is a property of epithelial tissue?
