Digestion and absorption: Human digestive system

The diffusion of solutes through transport proteins in the plasma membrane is known as facilitated diffusion. Aided diffusion is facilitated by three categories of transport protein: channel protein, gated channel protein, and carrier protein. The process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via a […]

Some molecules, such areas carbon dioxide, and oxygen can diffuse directly across the plasma membrane, but others have required assistance to cross its hydrophobic core. The Molecules diffuse that were across the plasma membrane with the help of membrane proteins such as channels and carriers in facilitated diffusion. Because these molecules have a concentration gradient,

A transport molecule aiding in the movement of chemicals across a biological membrane from a region of greater concentration to that of lower concentration is a process known as facilitated diffusion. Chemical energy is not needed, since compounds flow in the direction of their concentration gradient. The transport of glucose, amino acids, gases, and ions

Diffusion is defined as the movement of atoms, ions, or molecules from a high-concentration area to a low-concentration one. The transit of matter continues until equilibrium is established and the substance has a uniform concentration. Examples of diffusion Diffusion is a physical process that describes the net migration of molecules from a high-concentration region to

Introduction The digestion of protein in the body entails first breaking this complex molecule into peptides, each having a number of amino acids, then into individual amino acids and using those building blocks to make the proteins that our body needs for daily life. Absorption of proteins refers to the body’s ability to break down

The serum consequence of protein metabolism is blood urea nitrogen (BUN). This is one of the oldest heart failure prognostic indicators. The liver produces urea, which is then transported by that of the blood to kidneys for elimination. As the glomerular filtration rate (GFR) declines owing to sick or injured kidneys, BUN builds up in the

Abdominal Ganglia is also known as Celiac Ganglia or Coeliac Ganglia. These are two different masses of tissue that are found in the upper region of the Abdomen or Digestive Tract. These two Ganglia together are known as Celiac Plexus Proper. This is the branch of Neuroanatomy in which we deal with the different structures,

The five major senses of the human body are sight, smell, hearing, touch, and taste. The eyes are responsible for the perception of sight. The cornea, iris, sclera, pupil, retina, lens, ciliary body, conjunctiva, macula, vitreous body, retinal blood vessels, and optic nerve are all crucial structures that assist the eye execute its function. The

To work properly, the human body has a sophisticated mechanism that requires an excessive amount of biological activities. Many substances help our biological or physical constitution by facilitating certain functions essential for survival. These “chemicals” include enzymes and hormones. Specific molecular action is required to sustain, control, manage, and direct any biological or physical activity

Introduction ATP is the source of energy for every cell in your body that keeps everything running. Adenosine triphosphate is the biological form of energy. Your body’s most abundant energy-carrying molecule is ATP. It utilises the chemical energy contained in food molecules to power the cell’s functions. ATP is the universal currency of your body’s
