Uses and Examples of static electricity

What is Static Energy;
Static energy is stored energy or potential energy.Static energy is when electrical charges get charged on the surface of objects. These charged remain on an object untl they are released to the ground or just fade away naturally.






- Shocking a person; Rubbing materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons hold on to your body till they are released again.Therefore if you touch a someone they get shocked.

Respiratory System, Asthma& smoking

Respiratory System:
Your body is able to store what ever amount of energy it needs but it can't store any amount of oxygen. And so since you can't store the amount you need of oxygen your body takes it in a process called breathing which is the most important function in the respiratory system. We all have two lungs in our ribs that are surrounded by the ribcage and under it the Diaphragm. Every time you inhale the diaphragm contracts and moves downward and so your ribcage expands which produces air pressure inside of your lungs. And so when you take a breath the air comes in from your mouth or your nose and takes it way to the trachea and the lungs. Inside the lungs, the air moves to a smaller tubes which are called bronchial tubes. And so the air spreads to Alveoli which is surrounded by blood which is called Capillaries. From the capillaries the air moves to the blood. And so it gets rid of the Carbon Dioxide which is in your cells and takes it way through the blood into yours. And last the Diaphragm relaxes and exhales the gas out.

Asthma:

People who suffer from asthma feel tightness in their chest, they cough alot and they have a short breath. And so when you breathe the air goes to the tiny sacs(alveoli), which takes the oxygen in and kicks out the Carbon Dioxide. And so we all know that the air we breathe is not always healthy and that clean. What happens during an asthma attack is that when the air wants to get out dust inters and over reacts which will increase the chemicals that will cause the air paths to narrow that will make it much harder to breathe. And so that's why people that have asthma always have their inhalers with them to make it easier for them to breathe.


Smoking:
Smoking is really bad for you and can give you a heart disease easily. Cigarettes are made of a plant which called tobacco and many other chemicals. If instead of putting air in your lungs you put smoke in them it will damage them and they'll start turning black. this will give you a hard time breathing especially if your and athlete. Our a period of time smoking it can cause cancer to your lungs. Nicotine is a very bad chemical that is found in cigarettes which may cause you serious blood problems.

Mouth

The Mouth
When you put food in your mouth, it makes saliva which starts digestion. And so there are two parts of digestion, 1)Chemical , 2) Mechanical. What happens in the chemical part is that the enzymes change starch into sugar. And in the mechanical part it breaks down the food into small pieces. And so then the food slides to the esophagus.

Reflection

In term 2 Afra achieved a 5 and earlier in term 1 she got a 6. Instead of improving and learning from her mistakes she went down. Another point about her grade going down is that term 2 is harder than term 1 because instead of looking at term 2 grades the system this year has changed and anything in term 1 is affected and counts for term 2. Afra has faced difficulties and that clearly shows from her grade. She should really use her time wisely and come ask me if she has any questions. Also submitting homework on blogger really affected her grade. She was warned more than once but she decided not to listen. Afra could improve and achieve even a 7 if she focuses more in class next term. I wish her all the best!

Digestion Parts

Mouth;

Mechanical or physical digestion – chewing food and breaking into small pieces.

Saliva - Chemical digestion and breaking down carbohydrate.

- Slimes your food so it slides food down your esophagus

Esophagus

- Squeezes the food down to the stomach.

Stomach

- Stores food

- Mixes food (Mechanical digestion)

- Makes acid in order to help break down protein

Enzyme pepsin – Breaks down protein

- Ph-2 in your stomach when you get food inside.

Small intestine- Fats (lipids)

- Carbohydrates

- Proteins are all finished getting digested.

All of these are observed into your blood (small intestine)

Pancreas;

Makes all the important enzymes that go to small intestine to digest fats, carbohydrates and proteins.

Makes insulin in order for your body cells to suck up sugar (glucose).

Liver; greenish yellow

-It makes bile which is stomach in your gall bladder and sent to your small intestine.

- It filters the blood from your small intestine.

- Stores sugar so it can be released.
