Did you know...?

Hi Bloggers!!
This is the last post, so we thought that it could be funny to know some curiosities about The Respiratory System.


1. Horses only breathe through their noses
For humans, breathing through the mouth comes naturally and easily. The same is for many other mammals. Horses, have a flap of tissue which prevents them from breathing through their mouths.

2. Sneeze particles may not travel as fast as people think
In the past, modeling studies have estimated the velocity of a sneeze at 112 mph (180 km/h). However, a 2013 study found that a sneeze's velocity is even lower than the rates determined.

3. The lungs are the only organs that can float on water
Each of your lungs contains about 300 million balloon-like structures called alveoli. When these structures are filled with air, the lungs become the only organs that can float on water.

4. Some people can hold their breath for more than 20 minutes
The average time an adult can hold his or her breath is between 30 and 60 seconds. Stig Severinsen holds the Guinness World Record: he held his breath underwater for 22 minutes.


5. You lose a lot of water just by breathing
How much water do you lose from breathing? When at rest, humans exhale up to 17.5 milliliters

PARTS OF THE RESPIRATORY SYSTEM

Hi Bloggers!! 

Today we are going to explain you the parts of the Respiratory System.

1.Nasal Cavity: Condition the air to be received by the other areas of the respiratory tract.
2.Pharynx: Extends from the mouth to the larynx, and it becomes  continuous with the esophagus.
3.Larynx:  The prevention of foreign objects from entering the lungs by coughing and other reflexive actions
4.Trachea: It filters the air we breathe and branches into the bronchi.
5.Bronchi:  Permits rapid diffusion of oxygen and carbon dioxide.
6.Bronchioles: It helps to pass the air to the lungs
7.Lungs: In the lungs oxygen is taken into the body and carbon dioxide is breathed out.
8.Diaphragm:  The diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.

We hope that it helps.

Bye,
The Gorup.

RESPIRATORY DISEASES



I'll show you the different types of respiratory diseases. About 3 million people die from these diseases.
The most common respiratory diseases are:
  • Bronchitis: It's an irritation and inflammation of the bronchi. It produces breathing difficulties and accumulations of mucus. A symptom is coughing and one of the most common causes is the smoke's fumes.
  • Asthma: It's a common respiratory disease in children.The bronchi are inflamed and the work of the rest of the respiratory system is more difficult.The symptoms can be insomnia, fatigue, difficulty breathing and decreased of daily activities.

  • Pneumonia: It's the main disease that kills many children around the world. It can be caused by a virus, bacteria or fungi, which causes painful and limited breathing. The symptoms of pneumonia are fever, chills, loss of appetite, fast breathing and cough.

TABACCO AND EFFECTS

Hi bloggers!

Today I'm going to show you the effects of the tabacco.

The fumes that come from the tabacco contains:

  • Nicotine: Two or three drops of this substance can kill an adult. A cigarette contains 15 grams of nicotine. The nicotine creates the addiction.
  • Tar: It produces the cancer.
  • CO: It produces the heart diseases.

The principal causes of the consumption of tabacco are:

  • Heart diseases
  • Cancer
  • Respiratory diseases (for more information click here)
Cancer:
The risk of cancer depends of the duration of use, the age when you start to smoke and the number of the cigarette that you consumes in a day. The kind of cancer in men and women:


  • Men: Lungs, stomach, liver, esophagus and prostate. 
  • Women: Mama, lungs, stomach, colon and rectum.
Lungs:
The fumes of the tabacco affects to the lungs.

  • Increases the risks of colds.
  • Irritates the lungs and it becomes large.
  • The lungs become old faster.
  • Lung cancer.

Tabacco is too dangerous. We shouldn't smoke if we don't want problems with our health.


CONCLUSIONS OF THE ACTIVITY ABOUT BREATH/ HEARTRATE AND EXERCISE


Hi bloggers!!

We did an experiment about our pulse and breath. 

The project consists in: take the pulse and the breath, repose, we ran 2 minuts, we take the pulse and the breath, repose, we walk 2 minuts and finally we take the pulse and the breath again. 

After the project we have come to a conclusion. 

These are questions, about the project and the answers.


  1. Does your heartbeat remain the same after walking or running? Why?

No, because the body needs more energy.


  2. Does your breathing remain the same after walking or breathing?

No


    3. Why is it good for our bodies to have a faster heartbeat?

Because the heart distribuate more blood to the body.



    4. When can you see people breathing fast?



After doing sport.



When we do sport the breath and the pulse accelerates.

THE BREATHING PROCESS

Hi bloggers!

The breathing process is the inhale and the exhalate.

Inhale: the air enters through nasal cavities or mouth. When you inhale, the diaphragm contracts and air rushes in.

Exhale: the air leave through nasal cavities or mouth. When you exhale, the diaphragm relaxes and the air is forced out.

BREATHING EXPERIMENT IN CLASS (BALLOONS)


Hi bloggers!!


We did a project in class.

The project consists in see the process of the respiratory system in

the lungs.

The materials that we have were this:

-Two balloons

- A bottle

- Scissors


Steps:

      1. Cut the bottle in half

      2.  Cut a balloon in half

      3.  Put the balloon in the half of the bottle

      4.  Introduce the other balloon in the other part of the bottle.



 Conclusion: When we pull the rubber, the balloon blow up.

                      When we push the rubber, the balloon deflate.



Bye
