How air travels through the respiratory system(nose to lungs):

pharynx- larynx-trachea-bronchi-bronchioles-alveoli

Which is the odd one out:

esophagus because its part of the digestive system

Dust particles that are in the air in the respiratory system get out via the nasal cavities hairs-cilia

Smallest respiratory passageway: Broncioles

Separates mouth from nose: Palate

Windpipe: Trachea

Where gas exchange takes place: Alveoli

Stops food going the wrong way: Epiglottis

Air/food pass through: pharynx

Movement of air out of lungs: expiration

Main muscle involved in inspiration: Diaphragm

Membranes that cover the lungs and line the pleural cavity: Pleura

The volume of air inhaledor exhaled at each normal breath: Tidal Volume

Unhealthy and Healthy foods

Unhealthy foods usually contain large amounts of Sodium and Fat (of which is also partially saturated). Foods with empty calories have no vitamins or minerals, or fat, just plain calories, such as the cheetos used in the class for the experiment.

Name all the parts of the digestive system and their functions

Name all the parts of the digestive system and their functions:

Mouth

- Chemical Digestion [Carbohydrates] -> Enzymes

- Saliva Slimes your food so it can easily slide down your esophagus

- Mechanical (Physical) Digestion [Chewing food breaking it into smaller pieces]

Esophagus

- Squeezes the food down to the stomach

Stomach

- Stores Food

- Mixes food (mechanical digestion)

- Makes acid-> in order to breakdown 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 absorbed into your blood from your small intestine

Pancreas

- Makes all the important enzymes that go to digest fats, carbohydrates, proteins

Makes insulin in order for your body cells to suck up

Sugar (glucose)

Liver

- Makes bile which is stored in your gall bladder and sent to your small intestine to help digest fat.

- Filters blood from small intestine

- Store sugar, so it can be released

Large Intestine

- Stores undigested food

- Stores water

What is My MYP Grade

My MYP grade for the 2nd term in eighth grade, is 6. I was on the borderline between a 6 and a 7, and got a 6, because I got 32. The science areas I need to improve on are criterion c, meaning I should prepare more for tests, to push myself to a 7 in criterion c. Criterion F should also be worked on, as 4 was the latest grade for that criterion out of 6
