Digestion and absorption: Human digestive system

Because the human body is such a complicated entity, maintaining correct functioning requires a lot of energy. The energy source for usage and storage at cellular level is adenosine triphosphate (ATP). Adenosine triphosphate (ATP) is a nucleoside triphosphate with three serially linked phosphate groups, a nitrogenous base (adenine), and a ribose sugar. The connection between both […]

The stomach is the most important organ of the human body. According to biological definition, the stomach is a J-shaped, thick-walled organ located in the human body’s digestive system. It is a vital organ that stores undigested food and facilitates digestion by releasing various enzymes. This article talks about the stomach, its functions, stomach diseases

The small intestine is a long tube-like structure or organ that joins the stomach and large intestine together. The oesophagus, large intestine, and stomach give rise to the gastrointestinal tract in humans. It measures about 6-7 metres in length. It is highly convoluted and is present in the central and lower region of the abdominal

The digestive system includes the small intestine, which is the major gastric organ in the human body and is a part of the digestive system. This organ is responsible for the majority of digestive functions. So, the answer to the question, what is the small intestine, is that it is a tubular structure within the

The Skeletal system is the framework of the human body. Consider how you would build a car: start with the frame and then add the different components. The same is true of the human body! This structure is living and constantly interacts with the other body systems. The skeletal system comprises bones, cartilage, connective tissue, ligaments, and

Introduction The framework of our body is known as the skeletal system, which consists of bones, connective tissues, and cartilages. They are responsible for protecting and supporting the body’s tissue and internal organs. The skeletal system supports the human body and facilitates movements. It includes all bones and joints in the body. Each bone is

Terminology is required for all professions concerned with the representation, expression, communication, and education of particular information. Scientists, technologists, and professionals in any field require vocabulary to express and convey their expertise to inform, transmit, purchase, and sell their commodities. There isn’t a single specialization that doesn’t have its own set of units for categorizing

Introduction  Imagine a day without your sensory powers? It would be nearly impossible to perceive the world around us. Since your inception, the sense organs, including eyes, ears, tongue, nose, and skin, have held your hands strongly at various stages of life. It can be said that these are the only ways to have an

Introduction Digestive enzymes break down polymeric macromolecules into smaller building blocks, which helps the body absorb them. Nutrients are absorbed by our digestive system rather than the food we eat. Food must be broken down into nutritional components (from proteins), fatty acids and cholesterol (from fats), sugar (from carbs), vitamins, minerals and a range of

The movement of chemicals across a biological membrane from a high-concentration location to a low-concentration area using a transport molecule is known as facilitated diffusion. Chemical energy is not directly required because compounds flow in the direction of their concentration gradient. Glucose and amino acid transfer, gas transport, and ion transport are all examples of
