Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

The complex molecules of carbohydrates, proteins, and fats are transformed by chemical digestion into smaller molecules that can be absorbed and utilized by the cells. Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules.

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

chemical digestion: Explanation: The process of enzymes breaking down food into small molecules the body can use.

Mechanical digestion Food is taken into the mouth where it is broken down into smaller pieces by the teeth. As the teeth grip, cut and chew the food, saliva is released and mixes with the smaller food particles.

Food passes through the digestive system in the following order:

• Mouth.
• Esophagus.
• Stomach.
• The small intestine.
• Colon (large intestine)
• Rectum.

2. Digestion Is a 6-Step Process. The six major activities of the digestive system are ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination.

Gastrointestinal tract, also called digestive tract or alimentary canal, pathway by which food enters the body and solid wastes are expelled. The gastrointestinal tract includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus.

Mouth. The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.

Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing. It’s important to chew your food as much as possible, as taking longer to chew gives the enzymes in saliva time to begin the process of breaking down carbohydrates, a very important part of digestion.

Saliva also contains an enzyme called lingual lipase, which breaks down fats. A condition known as dry mouth (xerostomia) occurs when you don’t have enough saliva in your mouth. This can make it difficult for you to chew and swallow food.

The scale ranges from 0 to 14, with 7 representing neutrality. The lower end of the scale is acidic, and the higher end of the scale is alkaline. What is the pH of saliva? According to an article in the Hindawi journal, the normal pH of saliva is between 6.7 and 7.4, making it relatively neutral.

Adding dairy, not a sugary flavored creamer, can help counteract the acidity. Don’t brush. Avoid brushing your teeth after drinking high-acidity beverages such as soft drinks, fruit juices, cider, wine, or beer.

To find out your saliva pH, you can use a hydrion pH test paper at home. For the most accurate results, you should test your saliva in the morning before you drink or eat anything. Acidic pH is Acidic saliva caused by a pH level lower than 7 can result in significant damage to your smile.

Start to maintain a more alkaline pH in your body through diet by:

1. Improving your intake of vitamins and minerals through food choices and supplements.
2. Planning nutritious meals and snacks.
3. Reducing sugar and caffeine.
4. Keeping regular meal times—an important factor for maintaining blood sugar levels.
5. Drinking a lot of water.

Natural remedies to restore balance

1. Avoiding harsh soaps and douching. Soaps typically have a high pH, and using them to clean the vaginal area may increase vaginal pH.
2. Taking a probiotic supplement or suppository.
3. Changing tampons regularly.
4. Using barrier protection during sex.

Digestion is the mechanical and chemical break down of food into small organic fragments. Mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes.

The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.

The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.

There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.

The five steps involved in nutrition in animals, including human beings are as follows;

• Ingestion.
• Digestion.
• Absorption.
• Assimilation.
• Egestion.

The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Helping them along the way are the pancreas, gall bladder and liver.

The stomach has 3 main functions: temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer. mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach. digestion of food.

The core function of the human stomach is as an aid to diges- tion. The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility.

The human stomach is subdivided into four regions: the fundus, an expanded area curving up above the cardiac opening (the opening from the stomach into the esophagus); the body, or intermediate region, the central and largest portion; the antrum, the lowermost, somewhat funnel-shaped portion of the stomach; and the …

The stomach has three anatomical regions: cardiac, which contains mucous secreting glands (called cardiac glands) and is closest to the oesophagus. fundus, the body or largest part of the stomach which contain the gastric (fundic) glands. pyloric, which secretes two types of mucus, and the hormone gastrin.

As an adult, your stomach has a capacity of about 2.5 ounces when empty and relaxed. It can expand to hold about 1 quart of food.

The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.

1 – Stomach: The stomach has four major regions: the cardia, fundus, body, and pylorus. The addition of an inner oblique smooth muscle layer gives the muscularis the ability to vigorously churn and mix food.

Do this by placing one hand above your navel and the other below your navel. Your belly will move out as you inhale and float in as you exhale. Be sure your breath is moving your body. Speak on exhaled air as the belly floats in.

The pancreas is a long, thin organ located behind the stomach, in the upper left side of the abdomen. It produces enzymes to aid in digestion. If the pancreas becomes inflamed, the condition is known as pancreatitis.

Some weird early signs of pregnancy include:

• Nosebleeds. Nosebleeds are quite common in pregnancy due to the hormonal changes that happen in the body.
• Mood swings.
• Headaches.
• Dizziness.
• Acne.
• Stronger sense of smell.
• Strange taste in the mouth.
• Discharge.

06/13​Vinegar pregnancy test Remember, you will need white vinegar for this particular test. Take two tablespoons of white vinegar in a plastic container. Add your urine to it and mix it properly. If the vinegar changes its colour and forms bubbles, you are pregnant and if there is no change you are not pregnant.

how soon do you get symptoms of pregnancy? It takes about 2 to 3 weeks after sex for pregnancy to happen. Some people notice pregnancy symptoms as early as a week after pregnancy begins — when a fertilized egg attaches to the wall of your uterus.

That condition, called denied pregnancy, happens often. A few studies have estimated that one in 400 or 500 women are 20 weeks, or about 5 months, into their pregnancy before they realize they are with child.

The hook effect incorrectly gives you a negative result on a pregnancy test. This can happen during early pregnancy or in rare cases — even into the third trimester, when it’s pretty clear you’re preggers. During pregnancy your body makes a hormone called human chorionic gonadotrophin (hCG).

Can I get pregnant if I’ve never had my period? Yes, a girl can get pregnant before she gets her first period. Getting pregnant is related to ovulation. Because a girl can ovulate before having her first period, it is possible to become pregnant if she has sex.

With a completely flat stomach and maintaining her size 8 figure throughout, Charlotte had no idea she was about to become a mum. And she’s certainly not the only woman to not know they were pregnant until they go into labour. In fact, the phenomenon, known as cryptic pregnancy, isn’t so uncommon.

The short answer is no. Despite all of the claims out there, it isn’t possible to have a period while you’re pregnant. Rather, you might experience “spotting” during early pregnancy, which is usually light pink or dark brown in color.
