Upgraded B003 Ntbi1201 Microscopic Villi Microvilli Absorption — a labelled NEET Biology diagram with a definitions lexicon.
Microscopic view illustrating villi, microvilli, and absorption pathways. Labelled parts: Microscopic View, Small Intestine, Gall bladder, capillaries, Gallbladder, Amino Acid, Microvilli, Secretion, Pancreas, Enzyme, Liver, Order, Lacteal. The visual representation of a biological specimen as seen through a light or electron microscope. FYI: Staining techniques are often used in microscopic views to highlight specific organelles like the nucleus or mitochondria. 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. 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. The smallest and most numerous blood vessels, forming dense networks (capillary beds) that connect arterioles to venules. FYI: Gas exchange (O2 and CO2) and nutrient/waste exchange with surrounding tissues primarily occurs across the thin walls of capillaries. A small organ where bile is stored before it is released into the small intestine. The monomeric building block of proteins, containing an amino group, a carboxyl group, and a variable R-side chain. FYI: There are 20 standard amino acids that make up the vast diversity of proteins in all living organisms. Microscopic cellular membrane protrusions that increase the surface area for absorption. 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 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. The largest internal gland of the body, responsible for bile production, detoxification, and various metabolic functions. FYI: Bile produced by the liver contains no digestive enzymes but is essential for the emulsification of dietary fats. A taxonomic category that groups together families that exhibit a few similar characters. FYI: In plants, families like Solanaceae and Convolvulaceae are placed in the order Polymoniales based on floral characters. Lacteal is a labeled feature or concept in this upgraded BioAtlas image: A highly magnified diagram focusing on the brush border of intestinal epithelial cells. Labels must point out: Microvilli, Brush Border Enzymes, Capillaries (for sugars/amino ac...
