Digestion and absorption: Human digestive system

The pharynx is a musculo membranous tubular structure that is not aided by the support of any bony or cartilaginous matrix. It has distinct functions during breathing, deglutition, and vocalisation. In mammals, the pharynx is located where the digestive and respiratory tract combine. It is generally called the “throat”. The human pharynx is bent at […]

Peritoneal dialysis is a kidney failure treatment that uses the lining of the abdomen to filter blood. This lining is known as the peritoneum. A few weeks before peritoneal dialysis begins, the surgeon inserts a catheter, which looks like a soft tube, into the belly. The primary function of the kidney is to remove metabolic

Peristalsis definition in anatomy “Peristalsis is a sequence of contractions of the muscles in forms of wave that help transport food and liquid particles along the digestive tract to numerous processing organs.” What is Peristalsis?

In the body, pepsin is an endopeptidase enzyme, which means it breaks down proteins into peptides. As a digestive enzyme, it is produced by the main cells of the stomach lining and is one of the most important in the digestive systems of humans and many other animals, where it aids in the digestion of

Proteins are essential macronutrients in food because they provide essential amino acids as well as non-essential amino acids, which are required for the growth, repair, and preservation of tissues. Protein can be obtained from a variety of sources, and it is used to supply amino acids for the purposes of growth and repair. Nine amino

The large intestine is the terminal organ of the human digestive system. It consists of a caecum, colon, and rectum. The caecum is a tiny blind sac that contains symbiotic microorganisms. The caecum gives way to a slender finger-like tubular protrusion, the vermiform appendix, a vestigial organ. The caecum connects to the colon. The colon

Introduction The pancreas is an abdominal organ surrounded by the spleen, liver and small intestine and is placed behind the stomach.
