Upgraded B003 Ntbi1202 Hormonal Feedback Loops Controlling — a labelled NEET Biology diagram with a definitions lexicon.
Diagram illustrating hormonal feedback loops controlling digestion. Labelled parts: Small Intestine, Blood Vessel, Gall bladder, Gallbladder, Secretion, Pancreas, Stomach, Enzyme, releasing four hormones, Gastrin, Secretin, CCK, GIP. The longest part of the digestive tract where the majority of chemical digestion and nutrient absorption occurs. FYI: The internal surface area is vastly increased by finger-like projections called villi and microscopic microvilli. Tubular structures (arteries, veins, capillaries) that transport blood throughout the body. FYI: Cancerous tumors stimulate the growth of new blood vessels to sustain themselves, a process called angiogenesis. This small organ stores and concentrates bile, which is produced by the liver. Bile is essential for the digestion and absorption of fats and fat-soluble vitamins. FYI: The bile stored in the gall bladder is alkaline and contains bile salts, which emulsify large fat globules into smaller droplets. A small organ where bile is stored before it is released into the small intestine. The active transport of certain substances like H+, K+, and ammonia from the peritubular capillaries into the renal tubule. FYI: Tubular secretion helps in maintaining the ionic and acid-base balance of body fluids. A gland that has both digestive and endocrine functions (regulating blood sugar). 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. A biological catalyst, usually a protein, that accelerates chemical reactions by lowering the activation energy. FYI: Almost all enzymes are proteins, except for ribozymes which are catalytic RNA molecules. releasing four hormones is a labeled feature or concept in this upgraded BioAtlas image: A simplified diagram showing the small intestine sensing nutrients.
