Understanding Human Physiology: Past, Present, and Future

The study of human physiology has been ongoing for time immemorial. The first authentic available record is found in the Sushruta Samhita and Charak Samhita, dating back to around 600 BCE. They proposed that vata, pitta, and kapha regulate the body’s functions.

Bile: Formation, Functions, and Health Implications

Bile is a physiological fluid that is dark green to yellowish-brown in color and produced by the liver.

In humans, bile is produced continuously by the liver and drained by bile canaliculi to the right and left hepatic ducts. The right and left hepatic ducts join to form the common hepatic duct. The cystic duct from the gall bladder joins the common hepatic duct and forms the common bile duct.

Gastrin: A Gastrointestinal Hormone

Gastrointestinal hormones are biologically active polypeptides secreted from the endocrine cells of the GIT mucosa. These hormones enter the portal circulation, then flow into the systemic circulation, and finally reach the target tissue. Some gastrointestinal hormones also function as paracrine and autocrine hormones to regulate gastrointestinal (GI) functions. They are chemical messengers. 

Antioxidants| Self care| Health

Antioxidants are substances or molecules that neutralize or remove the free radicals and prevent their formation. In addition, they perform various critical bodily functions and are essential for a healthy life.

Antioxidants prevent the autooxidation of fats, thus reducing the formation of free radicals and reacting with formed free radicals.

Antioxidants are essential for life.
