Journey Through the Digestive System by Praniti Agarwal
Transcript of Journey Through the Digestive System by Praniti Agarwal
Both ways of digestion include the breaking down of food into smaller parts so that the
of food can occur.
the actual process of
breaking down the food
into smaller pieces and
particles inside your
is done by
chemical breakdown of
food which then makes the
food that you digested
into simpler compounds.
The macro-nutrients are

I think that my meal choices fulfill all my body's needs, because 49% of my breakfast are carbohydrates, 25% are proteins and 25% are fats. Research shows that your meal should consist of 50% carbohydrate, 25% protein and 25% fat.
intake of my breakfast is 1250.6 calories and that is healthy, because a teenagers meal should include 700-1400 calories.

-nutrients are very important substances that our body needs for nourishment and development. They play a very important part in keeping are body healthy and helping our body grow and keeping it healthy.

can be converted into glucose. You shouldn't consume too many

sugar to rise.
You could say that

our body won't run.
is an essential nutrient that we need to
consume, because it's necessary for growth and maintenance of our body. It is a long chain of
. Almost everything in our body can't function without
including our tissues and organs. There are 20 kinds of
in our body and it's a mixture of essential amino
(8) which help in maintaining healthy hair, skin and bones and non-essential
(12). Some amino acids can also be
straight into the muscle and then converted into energy. Foods with protein include meat, eggs, seeds, legumes, dairy and nuts.
Often people think that they should completely
from their diet, however
is a very important nutrient and it helps the other nutrients function properly. It's extremely necessary for us to consume the right amount of
, because it provides a normal body function and a healthy supply of energy, in fact without
it is almost impossible for us to live. There are 4 kinds of
Saturated, Trans, Polyunsaturated and Monounsaturated. Polyunsaturated and Monounsaturated
are better for your body and help reduce the risk of heart failures and diseases. In comparison, saturated
are less healthy and you should almost completely ignore trans
are organic compounds which are necessary in small portions, as it is an incredibly important nutrient which your body can't produce enough of. There are 13 essential
that you should definitely not avoid, these are
A, 8 types of
B's, C, D, E and K. Each of these have a different role and task in your body and are all equally important. It coverts food into energy, keeps our cells healthy and helps enhance the immune system.
C (ascorbic acid) can be consumed in the form of citrus juice (lime or lemon) and your body can

When you hear the phrase

perform the same tasks as
when it comes to helping our body. It helps your body grow, develop, build strong bones , transmitting nerve impulses and just simply keeping your body healthy. There are a lot of
but only some help in maintaining a healthy heart beat.
It is very important to consume water in our daily lives. If you avoid food in your daily lives, you can still survive, however if you don't drink enough
it's nearly impossible for you to survive. Water is a very important substance that is needed in our digestive system, because it removes toxins and waste from our body, this is why the more
that you drink the color of your urine tends to be clearer. It also helps to make necessary body fluids. Did you know that our body is made of 75% water? The sign which used to describe
is H2O which is made with 1 oxygen (O) and 2 hydrogen (H2).
is a very important element in plants for example fruits, vegetables and whole grains.

isn't broken down and is usually intact and passes quickly through the digestive system. If you don't consume enough
in your regular diet, you will face several symptoms like constipation and sluggishness.
helps to prevent colon cancer and keeps your colon clean. Did you know that
can even help with weight loss because it makes you feel full in your intestine, which makes you eat less?
What is the difference between physical and chemical digestion?
Tortilla chips contain a lot of carbohydrates and dietary fiber it also contains a little bit of protein and fat.
The Monterey Cheese is a healthy dressing used in breakfast nachos. It contains a lot of protein and a lot of fat, even though there is a lot of fat it's still healthy for you as it provides your body with energy.
2 Large eggs
These eggs are a good source of protein and
, but it contains a little bit of fat.
Guacamole is mostly made with avocado and a little bit of vegetables. It's a good source of fiber, vitamins and minerals.
The nachos dressing consists of olives, jalapenos, black beans and salsa sauce with vegetables which all contain a lot of vitamin and minerals.
This apple contains a lot of carbohydrates- around 96% of the apple. It also contains Vitamin C and Vitamin A. There is also a little bit of iron and calcium.
Low fat Vanilla Yogurt
This creamy mango contains low fat vanilla yogurt. It's very healthy, because it contains a lot of calcium, protein and carbohydrates. Also, since it's low fat not fat free, it contains a little bit of fat and
The soy milk contains a lot of magnesium, Vitamin B-6, Iron, Protein and Carbohydrates. It also includes a little bit of polyunsaturated and
which are considered
to be the 'good'
Mangoes contain loads
of vitamin C, a lot of Vitamin A, Vitamin B-6, Carbohydrates and potassium.It also contains a little bit of protein and fat.
In cottage cheese more than 50% of it is protein, there is also quite a lot of carbohydrates and a little bit of fat. It also contains calcium and a little bit of Vitamin B-12.
In India, cottage cheese is
very famous. It is called
paneer and when it's eaten
it's often mixed with other
vegetables and/or gravy .
The Digestive System
The process of the
begins in the
. Your teeth cuts up the food that you eat into relatively small pieces so that it makes it possible to digest. After that happens, saliva is produced in the
and gets mixed with the food in your mouth. In your saliva, there are chemicals called
that help in breaking down the starches in your food. There is an
in your saliva called the
which breaks down the starch into sugars.
The process in which our food goes down the
is called peristalsis. This process uses layers of muscle in your
and intestines. They move in a wave motion and push the food down the
is basically a tube which transports the food that we swallow into the stomach. In the root of our tongue, there are two tubes- the wind pipe which leads to the lungs and the
which leads to the stomach. When we talk, the
(a flap of cartilage) covers the
and when we eat the
covers the trachea (windpipe) so that our food doesn't go to our lungs. That's why when people eat while talking, their food often goes down the wind pipe and in order to get the food back into the mouth they cough
it out from the windpipe.
When the food goes down the

stream and, it is exocrine because it releases some of the juices into ducts.
