Natural Science and English exams

Hello!!

We've been talking about the exams we have to take. First of all RELAX!! You know more than you think, I'm sure you'll be fine. This week you have no homework, but many of you OWN ME MANY WRITINGS!!! Don't forget this!

Listening_ 27th November
Reading_ 28th November
Grammar_ 30th November (units 1 and 2 of the English book)
Speaking_ a long the days you'll be asked to take this exam.

About Natural Science tests:
Oral test: 
- Nervous system, locomotor system next week, from 27th to 30th November
- Digestive system and respiratory system  in two weeks, from 3rd to 5th Dicember
Writing test:
- Nervous system, locomotor system, dygestive system and respiratory system_ 4th Dicember

To help you with the oral part, here you have some examples of questions so you can see how it will be. The most difficult thing here is remember most of the vocabulary and calm down when they ask you, because it's easier than you think.

NERVOUS SYSTEM

What is the function of sensitivity?

The nervous system receives the information and interprets the information about the environment. It gives the orders for our body to respond the stimuli.

Name the parts of the nervous system

- Central nervous system: brain and spinal cord

- Peripheral nervous system: nerves

Explain what is the process that occurs in the nervous system in this picture

LOCOMOTOR SYSTEM

What is the locomotor system?

It's a system formed by the skeletal system and the muscular system. It's responsible for our movements (muscles) and our shape and structure (bones).

How the muscles are attached to bones?

They are attached to bones by tendons.

How the bones stay stuck in the joints?

Bones meet at joints, where they are held together by ligaments.

DIGESTIVE SYSTEM

What is digestion?

It's the process of breaking down food into nutrients that our body can use.

What happens when we eat an apple?

1. In our mouth we chew the apple and we smash it, the apple mixes with the saliva.

2. We swallow it and it's pushed into the pharynx, and it runs down the oesophagus.

3. It reaches the stomach and mixes with the gastric juices.

4. It travels to the small intestine, where mixes with the intestinal juices, bile (liver) and pancreatic juice (pancreas)

In the small intestine the nutrients are abosrbed.

5. In the large intestine water is absorbed and the remaining undigested food  leaves the body through the anus.

RESPIRATORY SYSTEM

What is respiration?

It's the process to obtain oxygen our body needs and to expel the carbon dioxide our body produces.

What is the difference between inhalation and exhalation?

In the inhalation, air enters through the nose, goes to the pharynx, travels down the larynx and the trachea and reaches the lungs through the bronchi. In the lungs, it runs down the bronchioles to reach the air sacs, where gas exchange takes place.

And in the exalation, the carbon dioxide runs up the way back till the nose or mouth.
