Asthma

Asthma is a disease that can be spread from generation to generation. It can also be caused by some allergies. Asthma is disease that causes asthma attacks. An asthma attack is when your bronchial tubes thin when dust particle go through them and cause them to contract and thus make it hard to breath, as air can't easily pass through. Inhalers are used to breath inc chemicals to stop the bronchial tubes to stop irritating and or contract.

Smoking

Smoking is is the process of inhaling tobacco as a gas and exhaling it through the usage of a cigar or cigarette. Smoking is an addictive habit, and causes many health as well as social problems. The nicotine in cigarettes is what makes smoking addictive. The tar in cigarettes slowly starts to blacken your lungs and in the process kills the skin cells of it, which has a high chance of causing lung cancer. Smoking can cause a myriad of other health problems, because cigarettes have many, many different dangerous chemicals.

Healthy and Unhealthy foods

There are many things that decide whether a food is healthy or not. Firstly you must look at the saturated fat levels in the food, to see how many grams of fat it has. Then you must reason whether the amount of calories it possesses is good for the weight it will add to your body. Then you must check how many vitamins and minerals it has, and if it has empty calories.

Empty calories are calories with minimal vitamins and minerals, and only provide excess calories, so basically their "empty" of what our bodies need.

What is My MYP grade?

My MYP grade for term 2 this year is 7. I am proud to get back to back 7s in science.

If my teacher were to write a letter to my parents about my grade, this is what I think it would be.

"Dear Parents of Shakeer Ahmad 8E,

Your son has been an excellent student this year and has earned the highest MYP grade possible of 7.

He can still do even better in the one world activities and the conclusions in his lab write-ups, and get 6/6s instead of 5/6s in the areas. He should practice activities like this at home.

Thank you,


Stephen Rhodes"

Names of all the parts of the digestive system and their functions

Mouth
Mechanical (Physical) Digestion > chewing food, breaking food into small pieces.
Saliva- chemical digestion > enzymes, amylase in saliva. Take out the carbohydrates.
-slimes food- slide food down the esophagus.
Esophagus
Squeeze the food down to the stomach.
Stomach
-Stores food.
-Mixes food (Mechanical digestion)
-Makes acid- in order to help breakdown protein.
Enzyme pepsin > breaks down protein
Pepsin is made in the stomach
Has a ph 2 in your stomach when you get acid.
Small Intestine
-Fats (lipids)
-Carbohydrates
-Proteins are all finished getting digested (chemical)
-All of these are absorbed into your blood by your small intestine.
Pancreas
Makes all the important enzymes that go to small intestine to digest fats (lipase enzyme), carbohydrates (amylase enzymes) and proteins (pepsin enzymes).
Makes insulin in order for your body cells to suck up sugar (glucose)
Liver
1. Makes bile which is stored in your gall bladder and sent to your small intestine to helo break down fat.
2. Filters the blood from your small intestine.

The mouth

The mouth has many abilities to start of the digestion process. It first breaks down the food physical using the teeth. Then it uses saliva to make the broken up food easier to pass through the esophagus, where it will go down to the stomach for chemical break down.
