Upgraded B003 Ntbi1201 Peristalsis Wave Esophagus Cross — a labelled NEET Biology diagram with a definitions lexicon.
Diagram showing peristalsis wave in the esophagus. Labelled parts: Cross-section, Esophagus, Stomach, peristalsis. A diagrammatic view of an organ or tissue obtained by cutting it at a right angle to its longitudinal axis. FYI: Transverse sections (T.S.) are standard in plant anatomy to study the arrangement of vascular bundles. A narrow, muscular tube that conveys food from the pharynx to the stomach through rhythmic contractions called peristalsis. FYI: The esophagus does not produce any digestive enzymes; its primary function is strictly transportation. A J-shaped muscular organ that stores food and performs the initial stages of protein digestion using acid and enzymes. FYI: The stomach lining secretes Proenzyme Pepsinogen, which is converted into active Pepsin by the highly acidic HCl. peristalsis is a labeled feature or concept in this upgraded BioAtlas image: A cross-section diagram of the pharynx and esophagus. Use arrows to illustrate the wave-like muscular contraction (peristalsis) moving a food bolus from the throat into the stom...
