The small intestine of the human digestive system – parts (duodenum, jejunum and ileum), its functions (digestion, absorption) and its structure (villi, layers). Learn about its role in the absorption of nutrients, including vitamins and minerals, how peristalsis drives food and the effects of infections. The anatomy of the small intestine, its functions and its importance to the digestive system

The Pancreas – Structure, Function and Hormonal Secretions

June 30, 2023June 30, 2023 - by Jaishree Gorane - Leave a Comment

The pancreas is a glandular organ located in the abdominal cavity. It has a complex structure consisting of various parts, including the head, body, and tail. Functionally, the pancreas plays a crucial role in both the digestive and endocrine systems. It produces and secretes digestive enzymes and juices, essential for the breakdown and absorption of nutrients. Additionally, the pancreas secretes important hormones like insulin and glucagon, which regulate blood sugar levels. The pancreatic structure, function, and hormonal secretions are vital for maintaining overall health and metabolic balance.

Structure and functional units of the Liver

June 28, 2023June 29, 2023 - by Jaishree Gorane - 1 Comment

The liver, a vital organ in the human body, consists of numerous structural and functional units called Hepatic lobules. Each lobule consists of hepatic cells, sinusoids and a central vein. The hepatocytes in the lobules perform various metabolic functions, such as detoxification, protein synthesis and bile production. Understanding the intricate structure and function of the liver units is crucial to understanding liver physiology.

Difference Between Chemosynthesis and Photosynthesis

June 23, 2023December 23, 2023 - by Jaishree Gorane - Leave a Comment

Chemosynthesis and photosynthesis are two different processes with different energy sources and reactions. While photosynthesis uses light energy, carbon dioxide and water to produce glucose and oxygen, chemosynthesis relies on chemical energy from inorganic compounds and produces organic compounds without the involvement of light or oxygen.

June 22, 2023June 23, 2023 - by Jaishree Gorane - Leave a Comment

Chemosynthesis is a process where chemosynthetic bacteria convert inorganic compounds into energy-rich organic compounds. It occurs in environments lacking sunlight. The equation for chemosynthesis is carbon dioxide + water + inorganic compounds → organic compounds + sulphur compounds. Chemosynthetic bacteria, like sulphur bacteria, iron bacteria, and nitrifying bacteria, are examples of organisms that carry out chemosynthesis. Chemosynthesis differs from photosynthesis in energy sources and reactions.

Salivary Glands – Definition, Types, Location, Size, Ducts, Diagram, Characteristics, Secretion, Structure and Function

May 30, 2023June 2, 2023 - by Jaishree Gorane - Leave a Comment

Salivary glands are exocrine glands responsible for saliva secretion. They have acinar cells for saliva synthesis and ductal cells for transport. Myoepithelial cells aid saliva movement. Major glands include parotid (largest), submandibular, and sublingual (smallest). Ducts are Stensen’s (parotid), Wharton’s (submandibular), and multiple (sublingual). Saliva lubricates, digests, and protects. Understanding their structure and function is vital.

Gastric Glands – Location , Structure, Types, Secretion and Functions

May 29, 2023May 29, 2023 - by Jaishree Gorane - 1 Comment

Gastric glands, present in the stomach lining, play an important role in digestion. Structurally, they are made up of different cell types, including parietal, chief, and mucous cells. These glands secrete gastric juice, which consists of hydrochloric acid, pepsinogen and mucus. The secretions help break down food, sterilisation of ingested pathogens and absorb essential nutrients, thus fulfilling important functions in the digestive process
