Gastric Pit The opening of a gastric pit into the stomach, surrounded by the rounded apical surfaces of the columnar epithelial cells of the mucosa.

Ileum Longitudinal

Figure 1-81

Small Intestine, Villi of Ileum (Longitudinal Section) Numerous pale goblet cells punctuate columnar epithelium that covers each villus. Core of villus contains small blood vessels and blind lymph channel (lacteal). Deep in crypts are endocrine cells, identifiable as dark, round nuclei in a noncolumnar cytoplasm. Human. (X50)

Parenchymal Hepatocytes

Figure 1-84a

Liver with Central Vein and Sinusoids

Parenchymal hepatocytes lie in radial arrangement around central vein that is lined with single endothelial layer. Cords of hepatocytes are separated by spaces (sinusoids). Sinusoidal surface is covered by microvilli. (X100)

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
