This vessel is identified as a(n) ____ due to the _____

(C) arteriole / one to two layers of smooth muscle
(D) capillary / absence of smooth muscle
Transcribed Image Text:This image shows a histological cross-section of the human esophagus. The esophagus is lined with stratified squamous epithelium, which is visible as the densely packed layer on the left side of the image. This epithelial layer protects against mechanical stress as food and liquids pass through.
Beside the epithelium, there is a submucosal layer, which appears less dense and is made of connective tissue with blood vessels and nerves.
On the right side of the image, the structure with a circular arrangement represents a cross-section of a blood vessel, likely an artery, due to the thick muscular wall surrounding it.
This type of histology is important for understanding the structure and function of the esophagus and can help identify pathological changes in diseases such as esophagitis.
