Unit 8: Physiology of human body systems
Learning aim C: Explore the physiology of the digestive system and the
use of
corrective treatments for dietary related diseases
Title: Nutrition and health
Introduction:
I'll submit a report that explains and compares how a specific dietary issue impacts the digestive
system's regular functioning. I'll also assess the effects and efficacy of treatments employed to tackle
the disease a nutritional problem
The digestive system's role is to absorb the nutrients food. Food is broken
down into smaller molecules that are absorbed by the body during digestion.
The process of chemical digestion is called hydrolysis, and it involves the usage
of water. To break down molecules, digestive enzymes are used. Enzymes for
digestion are utilised to hasten the process of hydrolysis
Mouth - The salivary glands secrete saliva, which contains an enzyme called
amylase, which breaks down starch in diet into simple sugars. Chewing breaks
down food into tiny molecules that are easier to digest. Chewing is mechanical
digestion, whereas secreting saliva is chemical digestion.
Oesophagus – The oesophagus is a muscular tube that links the mouth to the
stomach. It contracts to convey food through the digestive system. Peristalsis
is a wave-like contraction that begins in the oesophagus and transfers eaten
food balls to the stomach.
Stomach – The stomach produces hydrochloric acid, which is used to kill
microorganisms. The stomach's primary role is to store and break down
digested food. Chemical digestion is a method of digestion in which enzymes
are produced to decompose the meals. The discharge of pepsin into the
stomach, for example, is chemical digestion that breaks down proteins. In the
stomach, called peristalsis movements of smooth muscle help with mechanical
digestion. This food is broken down even more into smaller bits.
Liver – To break down lipids into fatty acids, the liver emits bile into the small
intestine. Pancreas - The pancreas is an organ that secretes pancreatic fluid
into the small intestine to neutralise the bowel's hydrochloric acid.
, Small intestine – The small intestine is an organ that collects nutrients from
meals into the bloodstream through villi. This is a chemical digestion because it
necessitates the production of enzymes by the small intestine walls. Amylase
break starch into simple sugars, lipase starts to break down lipids into lipids,
and protease breaks down into amino acids, among other enzymes.
Large intestine – The large intestine is an organ that is in charge of absorption
of nutrients of water and mineral ions from non-digested food and the
elimination of waste products. It links to the rectum and enables the material
to go there. Water is absorbed through osmosis in the large intestine, while
nutrients including such sodium are absorbed through sodium channels.
Rectum – To keep material that hasn't been processed as food until it's
expelled from the body.
Anus - The waste is released in the type of faeces through the aperture at the
bottom end of the digestive. The two mechanisms through which the body
breaks down food are mechanical and chemical digestion. Physical movements
are used to break down food in mechanical digestion. The use of enzymes to
decompose foods is known as chemical digestion. The action of the mouth to
break down food is an example of mechanical digestion. The release of saliva in
the mouth, which uses amylase to break down starch from foods into simple
sugars, is an example of chemical digestion.
