reflection [16- 22 nov]

Over this past week, i did some research and found out more about digestion. i completed my learning targets. i will be going on holiday so i might not be able to record everything in my next week's reflection.

Find out how food is broken down

When you smell a tasty food

, see it, or think about it, digestion begins. Your mouth starts to get watery. When you do eat, the water breaks down the chemicals in the food a bit, which helps make the food easy to swallow. Your tongue helps out, pushing the food around while you chew with your teeth. When you're ready to swallow, the tongue pushes a tiny bit of food called a bolus toward the back of your throat and into the opening of your oesophagus, the second part of the digestive tract.
On the Way Down The oesophagus is like a stretchy pipe that's about 18 inches long. It moves food from the back of your throat to your stomach. But also at the back of your throat is your windpipe, which allows air to come in and out of your body. When you swallow a small amount of food or liquids, a special flap called the epiglottis flops down over the opening of your windpipe to make sure the food enters the oesophagus and not the windpipe. If you've ever drunk something too fast and started to cough, and heard someone say that your drink "went down the wrong way," the person meant that it went down your windpipe by mistake. This happens when the epiglottis doesn't have enough time to flop down, and you cough without thinking about it to clear your windpipe. Once food has entered the oesophagus, it doesn't just drop right into your stomach. Instead, muscles in the walls of the oesophagus move in a wavy way to slowly squeeze the food through the oesophagus. This takes about 5 seconds.
Your stomach, which is attached to the end of the oesophagus, is a stretchy sack shaped like the letter J. It has three important jobs:
To store the food you've eaten
To break down the food into a liquid mixture
To slowly empty that liquid mixture into the small intestine
The stomach is like a mixer, churning and mashing together all the small pieces of food that came down the oesophagus into smaller and smaller pieces. It does this with help from the strong muscles in the walls of the stomach and gastric juices that also come from the stomach's walls. In addition to breaking down food, gastric juices also help kill bacteria that might be in the eaten food.

This is how food is broken down. to put it shortly, food is broken down through digestion.

Know more about the digestive system and each organ's function.

Mouth
Food is ingested into the gastrointestinal tract through the mouth, or oral cavity. Associated accessory organs such as the teeth, tongue and salivary glands begin the processes of mechanical and chemical digestion through mastication. The mouth also begins the propulsive process of swallowing.

Pharynx
From the mouth, food is passed into the oropharynx and then to the laryngopharynx. Sequential contractions of the muscles in the wall of the gastrointestinal tract create a peristaltic wave, squeezing the food into the oesophagus.

Oesophagus
Contraction of the muscular wall of the oesophagus creates a peristaltic wave which continues to propel the food along the gastrointestinal tract and into the stomach.

Stomach
The stomach acts as a temporary storage site for food where chemical digestion of proteins begins, and food is converted into chyme. Mechanical digestion is also carried out as peristaltic waves mix the food with gastric juice. A few fat soluble substances are also absorbed through the lining of the stomach into the blood stream.

Small Intestine
The small intestine is the body’s main digestive organ, where digestion is completed and virtually all the absorption of the digestion products into the blood stream occurs. Mechanical digestion and propulsion of the food through the gastrointestinal tract is achieved by the alternate contraction of the smooth muscles of the small intestine wall. Enzymes conveyed via ducts from the pancreas, liver and gallbladder (accessory organs), together with enzymes secreted from the cells lining the small intestine function to chemically digest the food. The soluble digestion products are taken up into the blood stream by passive and active mechanisms.

Large Intestine
The large intestine functions to absorb water from the indigestible food residues in its lumen, and then remove the semi-solid faces from the body through defecation. Faces are propelled through large intestine via peristaltic waves, mass movements and haustral churning. Defecation is a reflex action which is triggered by rectal distension.

Find out how to have a healthy diet

Today, I did some research on how to have a healthy and balanced diet.

In the website, it said that healthy eating is not about strict nutrition philosophies, staying unrealistically thin, or depriving yourself of the foods you love. Rather, it’s about feeling great, having more energy, and keeping yourself as healthy as possible – all which can be achieved by learning some nutrition basics and incorporating them in a way that works for you. Choose the types of foods that improve your health and avoid the types of foods that raise your risk for such illnesses as heart disease, cancer, and diabetes. Expand your range of healthy choices to include a wide variety of delicious foods. Learn to use guidelines and tips for creating and maintaining a satisfying, healthy diet.

Keep portions moderate, especially high-calorie foods. In recent years serving sizes have ballooned, particularly in restaurants. Choose a starter instead of an entrée, split a dish with a friend, and don’t order supersized anything.
Eat plenty of fruits, vegetables, grains, and legumes—foods high in complex carbohydrates, fiber, vitamins, and minerals, low in fat, and free of cholesterol. Try to get fresh, local produce
Drink more water. Our bodies are about 75% water. It is a vital part of a healthy diet. Water helps flush our systems, especially the kidneys and bladder, of waste products and toxins. A majority of Americans go through life dehydrated.
Limit sugary foods, salt, and refined-grain products. Sugar is added to a vast array of foods. In a year, just one daily 12-ounce can of soda (160 calories) can increase your weight by 16 pounds. See suggestions below for limiting salt and substituting whole grains for refined grains.
Don’t be the food police. You can enjoy your favorite sweets and fried foods in moderation, as long as they are an occasional part of your overall healthy diet. Food is a great source of pleasure, and pleasure is good for the heart – even if those French fries aren’t!
Get moving. A healthy diet improves your energy and feelings of well-being while reducing your risk of many diseases. Adding regular physical activity and exercise will make any healthy eating plan work even better.
One step at a time. Establishing new food habits is much easier if you focus on and take action on one food group or food fact at a time

reflection [ 9-15 nov]

i was at my aunts house for most of this week. i had trouble doing research on the digestive system and stuff. so i plan to do this next week. my aunt had no internet. i completed my graph on the food i ate. i dont think that im doing well. i need to work faster and more consistent

Reflection [2-8 nov]

i only realised i had to do this blog on the 4th of nov. so i created it and stared the meal log. i had a bit of trouble remembering the foods i ate on the previous days. overall, it was still okay. i plan to do research next week.

food log

This is what i ate.
Rice and alternatives are the most.
next was meats and milk stuff.
followed by vegetables and fruits
lastly, we have oil and fat
