Human body: ORAL TEST 1st TERM

Good morning!!

I hope you are enjoying your loooooong weekend. As I told you, here you have the questions we'll ask you on 12th December about human's body systems:

NERVOUS SYSTEM  

1. The nervous system carries out the function of sensitivity. 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 to the stimuli.

2. Name the parts of the nervous system

- Central nervous system: brain and spinal cord

- Peripheral nervous system: nerves

3. Explain what is the process that occurs in the nervous system in this picture (you will have a picture o explain it, the one below it's just an example)

The drivers hear the siren and see the ambulance lights (stimuli). His eyes and ears send the information to the brain. The brain receives and interprets the information and gives an order to his hands to step aside to let it pass (response).

DIGESTIVE SYSTEM

1. What is digestion?

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

2. 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 absorbed.

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 nouse, 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 exhalation, the carbon dioxide runs up the way back till the nose or mouth.
