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
Small Intestine- Structure , Functions and Movement in the Digestive System Read MoreThe 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.

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.
Difference Between Chemosynthesis and Photosynthesis Read More
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.
