Where & How Does Nutrient Absorption Take Place in the Body?

With the world engulfed in the wrath of serious diseases, we are also stressing healthy eating. It is because most of the disorders are effects of unhealthy eating practices. Even our children are inclined towards junk more than fresh homemade foods. Since governments are spending fortunes on educating people about the urgent need to switch, there is a push towards a diet full of vitamins, minerals, and essential nutrients. Since we are already into the healthy route, let’s learn the bodily process of nutrient absorption and pass the exciting information.

Complex carbohydrates and water, and minerals from the eating plan are assimilated from the top intestinal wall chamber. The incorporated components primarily cross the mucous membranes into the blood system and are passed to other body areas for stockpiling or further chemical conversion. This stage of the gastrointestinal tract system’s procedure varies according to the type of nutrient.

What exactly is the process of digestion?

The digestive system consists of the gastrointestinal (as well known as the GI tract and a digestive tract) and the liver, pancreatic, and gallbladder. The Digestive system is a collection of body cavities connected by a lengthy, contorting duct that runs from the mouth to the anus. The GI tract comprises hollow organs such as the mouth, esophagus, abdomen, intestinal tract, large intestine, and sphincter. The gastrointestinal system’s vital body parts are the liver, pancreatic, and gallbladder.

The small intestine has three sections. The first section is known as the duodenum. The jejunum is in the center, and the ileum is at the bottom. The appendix, cecum, colon, and rectum are all parts of the intestinal tract. The appendix is a sack connected to the cecum in the form of a finger.

To begin with, the first section of the small intestine is the cecum. The next is called the colon. Our intestinal tract also has a terminal point known as the rectum.

Microbes in your digestive tract aid in digestion. These are also known as gut flora or symbionts. Components of your nervous, as well as circulatory systems, can also assist. Nerve endings, hormone levels, microbes, plasma, and abdominal organs all collaborate to break down the foods and beverages you consume daily.

What is the significance of the digestive process?

Digestion is essential even though your body requires nutrients and vitamins, and drinks to work effectively and promote health. Supplements include protein molecules, lipids, complex carbs, vitamin supplements, NIH link, mineral resources, NIH external link, and water. Your digestive system converts nutrients into smaller pieces that your body absorbs and uses for power generation, development, and repair of the body.

  • Proteins degrade into amino acids.
  • Lipids are then broken down into glycerol and fatty acids.
  • Disaccharides are broken down into glucose.

How well does my digestive tract function?

Every component of your digestive tract contributes to the transportation of nutrients and fluid through your GI tract, breaking down the food and fluid into tiny chunks, or even both. When food is broken down into manageable sufficient pieces, your body can soak up and deliver materials to which they are required. Your digestive system absorbs and digests solid wastes become stool. Nervous system and hormone levels aid in regulating the process of digestion.

The digestion procedure of different parts:

Organ and their Motion

  • The mouth is used for munching the food.
  • The digestive tract does muscular contractions for the food to move.
  • The abdomen’s function is that the upper belly contraction helps relax, allows food to move, lowers tummy tissue, and mixes meals with digestive juice.
  • The small intestine, too, helps in muscular contractions.
  • The pancreas doesn’t help in any particular motion whatsoever.
  • The liver doesn’t help in any particular motion whatsoever.
  • The large intestine, too, helps in muscular contractions.

Signs Your Digestive System is Working Incorrectly

Since we are talking about the digestive system, let’s see some signs that show it is not working correctly. Here are the following:

Stomach Disturbances

If you are suffering from constipation, heartburn, bloating, gas or diarrhea, you can be sure that the digestive system is not working efficiently. Your body is not adjusting the foods properly in your body, so you are facing such correctly.

Sudden Weight Change

Losing a drastic amount of weight can result from an inefficient digestive system, and it is similar when people put on weight also. Since your body is not working correctly, you will not absorb the nutrients properly, regulate blood sugar or even store fat.

Sleep Disturbances

One can develop skin irritation due to sleep disturbances. Insomnia and disturbing sleeping patterns can also signify your digestive system is not working correctly.

Skin Problems

Eczema is a significant sign of gut problems. Improper food intake or inefficient digestive system can lead to several skin problems.

How would food pass through my digestive system?

Peristalsis is the movement of nutrition through your Gastrointestinal system. Your GI tract’s massive, hollow organ systems have a thin coating of muscle that allows their walls to relocate. The motion forces passage of food through your Gastrointestinal system, mixing the components of each part of the body.

The meal is pushed down the digestive tract through the contraction of muscles. When the muscle behind the meal contract, they also the meal forward. Simultaneously the muscles ahead of your food relax to enable easier movement.

Let’s look into detail the food journey from your plate to distribution and absorption in the body.


Once you eat, the meal begins to move through your gastrointestinal system. Once you ingest, the meal is pushed into your esophagus by your mouth. To avert clogging, a tiny opening of tissue called the epiglottis crinkles over your throat, allowing food to move into your esophagus.


When you start gulping down, this becomes completely automated. Peristalsis begins when your central nervous system sends the message to the musculature of your esophagus.

Sphincter of the lower esophagus

When the meal approaches the edge of your esophagus, a ring-shaped muscle known as the lower esophageal sphincter unwinds and allows food to move into your abdomen; this sphincter generally stays closed to prevent food particles from seeping back into the esophagus.


When food reaches your belly, the abdominal muscles combine it with digestive fluids. The abdomen gradually unloads its entirety, known as chyme, into the intestinal tract.

The small intestine

The small intestine’s muscles combine meals with digestive fluids from the pancreatic, liver, and intestine, then push the combination forward for any further digestive processes. The small intestine’s walls absorb moisture and metabolize nutrition into your blood system. The waste materials of digestion start moving into the intestinal tract as muscular contractions keep going.

The large intestine

Further water will move from your Gastrointestinal system into your blood system through your intestinal tract. Microbes in your considerable intestine aid in the collapse of residual nutrient content and the production of vitamin K. Stool is made up of waste products of digestion, which include particles present in foods that are too huge.

What occurs to the meals that have been metabolized?

The small intestine absorbs most of the nutrient levels in your diet, and your cardiovascular system transports them to other regions of the body for storage or even use. Specialized cells aid in absorbing nutrient content through the gut wall and into the blood system. Glucose molecules, amino acids, glycerol, and some vitamins and salts are carried to the liver by your blood. When necessary, your liver stores, procedures, and provides nutrition to the remainder of the body.

The lymph network is a method of vessels that transports white blood cells and lymph, a liquid, across the whole of your body to fight infectious disease and soak up fats and oils, and vitamin supplements.

Sugars, amino acids, fatty acids, and glycerol are used by your body to create compounds you require for power generation, growth, and repair of damage.

What is the mechanism by which my body regulates digestion and absorption?

The digestive system is managed by your hormone levels and nervous system working around each other. Messages pass throughout your Gastrointestinal system and from your Gastrointestinal system to your central nervous system.

Hormone levels

Hormones that regulate how your digestive tract works are produced and released by cells lining your small intestine and large intestine. The above hormone levels inform your body when to make digestive juices and transmit messages to your brain to indicate if you are hungry or full. Your pancreas also secretes hormones that help indigestion.

Nervous system

Nerves communicate your central nervous system (brain and spinal cord) to your digestive system and control digestion processes. For instance, when you see and smell things, your brain sends a signal to your salivary glands, causing them to “start making your mouth water” in preparation for eating.

You even have an enteric nervous system (ENS), which consists of nerve endings inside the wall surfaces of your gastrointestinal tract. Once a meal extends the walls of your Gastrointestinal system, the nerve endings of your ENS discharge several substances that either pace up or slow down meal motion and the manufacturing of digestive juices. The nerve impulses transmit data to your gut muscles, which contract as well as loosen up to move food through your digestive tract.


What you consume does not define you. However, individuals are defined by what their body consumes or absorbs. This is since your body doesn’t utilize all of your meals. Although if you do not obtain nutrients in your meals, they won’t help your molecules, muscles, brain, or other organs.

Begin reaching out to your roots and indulging in seasonal fruits and vegetables. These have the maximum flavor and nutrients. If you aren’t sure about body mechanisms, you can consult a nutritionist to guide you with a diet plan to incorporate all the necessary nutrients required to lead a healthy life.
