What do chief cells produce quizlet?
What do chief cells produce quizlet?
Chief cells secrete Gastric Lipase which functions to break down fats into smaller fatty acids that can be further digested in the intestine.
What does chief cells produce?
pepsinogen
Structure. The chief cells secrete pepsinogen, a moderately sized zymogen protein with a molecular weight of 40,400. Pepsin, an enzyme with a molecular weight of 32,700, is formed in the acidic environment of the stomach when pepsinogen loses its activation peptides.
What hormone is produced by the chief cells?
Chief cells: The chief cells manage the secretion of parathyroid hormone (PTH). When the cells are viewed, they contain prominent Golgi apparati and a developed endoplasmic reticulum to help with the synthesis and secretion of the hormone.
What hormone is produced by the chief cells quizlet?
Chief Cells. Releases pepsinogen which is then cleaved by HCl and turned into pepsin which can break down proteins. What type of digestion does HCl do?
What do neck cells of gastric pits secrete quizlet?
The mucous neck cells that line the gastric pits produce a thin mucus that is chemically different than the mucus produced by the surface goblet cells. The gastric glands are made up of four types of cells. The parietal cells produce intrinsic factor and hydrochloric acid.
What is pepsinogen produced by?
gastric chief cells
Pepsinogens are synthesized and secreted primarily by the gastric chief cells of the human stomach before being converted into the proteolytic enzyme pepsin, which is crucial for digestive processes in the stomach.
Do Chief cells secrete hydrochloric acid?
Explanation: The stomach contains several cell types, each with a specific mechanism of action. Chief cells produce pepsinogen, which is converted to pepsin by hydrochloric acid in the stomach. Parietal cells produce hydrochloric acid, allowing this conversion.
What is produced by Enteroendocrine cells?
Enteroendocrine cells produce a range of gut hormones that have key roles in the coordination of food digestion and absorption, insulin secretion and appetite.
What hormone do the Principal chief cells produce and secrete?
It produces and secretes parathyroid hormone in response to low calcium levels.
Which cells are responsible for the production of circulating antibodies?
Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.
What cells are found in the gastric pits?
Gastric Pits
- Goblet cells – secrete mucus to form a protective layer around the stomach lining.
- Parietal cells – secrete hydrochloric acid which is responsible for creating a low pH environment in the stomach.
- G cells – secrete gastrin (stimulates release of stomach acids to increase stomach acidity)

Where are the chief cells located in the stomach?
Chief Cell Function produces pepsinogen ( becomes pepsin when it is activated by HCl in the stomach Chief Cell Secretions 1. lipase- fat digesting enzyme 2. rennin- digests milk protein, casein Enteroendocrine Cell Location deep within the pit near the blood supply (in the pyloric region) Enteroendocrine Cell Function
Where are the mucous cells located in the stomach?
1. Mucous Cells 2. Mucous Neck Cells 3. Parietal Cells 4. Chief Cells 5. Enteroendocrine Cells Mucous Cells Location 1. line the gastric pits (more superficial aspects) 2. located in the cardiac and pyloric regions of the stomach Mucous Cell Biology 1. simple columnar epithelium 2. contain tight junctions
How are endocrine cells protect the stomach lining?
Endocrine Cell Secretions histamine, serotonin, and somatostatin Protection of the Stomach Lining 1. Mucous Cells secrete HCO3- to neutralize pH 2. Mucous Cells contain tight junctions to prevent gastric juices from leaking into underlying tissues
