The circulatory system

The circulatory system

1.what is the circulatory system?

 The circulatory system, is one of the most
important system, because the blood carry 
oxigen and nutrients.

 2.  wich are the 
functions of the 
circulatory system?

1. The circulatory system is an organ system that

permits the blood circulate and transport   inside 

nutrients and  oxigen to the cells and eliminates the
waste substances.

2. The circulatory system consist, the blood, heart and blood vessels.



3. The blood vessels

The blood vessels:

1. artery: Is a blood vessel that carry blood away the heart.
2. veins: Is a blood vessel that carry blood to the heart.
3. capillary: Is the small blood vessel.

4. what are the red cells and the white cells?

Red blood cells:

The red blood cells are the most important in
the blood,the red blood cells they   carry 
oxigen into the lungs.  

white blood cells:

The white blood cells, the cells only works in
the protections of the infections ill or viruses.
All the white blood cells of the blood
have  nucleus and plaquets. 







5. The heart

The heart is the principal organ in the body .
The heart only work and help the blood.The 
heart pumps the blood and carries it to the whole 
body.



6. Fun facts

1. It takes about 20 seconds for a red blood cell to circle the whole body.
2. In the body aproximatle of red blood cells are 5 million.
3. About 8 million, blood cells die in the human body every second.
4. About 8 million, blood cells born in the human body every second
5. your heart beats 70 times a minut.

THE CIRCULATORY SYSTEM

Definition: The Circulatory System is a system that transport all the blood to the body.

The circulatory system is composed of the heart and blood vessels, including: Arteries, veins and capillaries.

Veins: Tube that carries blood to the heart from other parts of the body.

Capillaries: A very thin tube, especially one of the smaller tubes that carry blood around the body.

Arteries: One of the thick tubes that carry blood from the heart to other parts of the body.

The heart is the most important organ of the circulatory system, because it pumps the blood to our body.

In the blood we have Red blood cells, White blood cells and platelets.

Red blood cells: Its function is to transport oxygen to body tissues and exchange it for carbon  dioxide.

White blood cells: Is in charge of fighting germs.

 

Platelets: Are small cells that are in our blood. When you make a wound the platelets are joined in a crust, so that stop you bleeding.

The Circulatory System we need to live.

RESPIRATORY SYSTEM

The respiratory system

Though respiration we take in the in the oxigen our cells need to transport into energy and our body releases the carbon dioxide it doesn´t need.

In the repiratory system there are two processes:

Pulmonary ventilation and gas exchange

Pulmonary ventilation is the moment of air into and out of the lungs.This process is performed by the inspiration and expiration.

Inspiration:

During inspiration, your diaphragm contracts and your chest cavity expands.

 1. Notrils where it is warmed up and cleaned of imputities by mucus and 
     the fine hairs inside the nasal cavities.
 2. The air travels through larynx ,into your windpipe, then into your bronchi 

     and  your bronchioles and finally reaches your lungs.

Expiration:

During expiration,your diaphragm relaxes and your chest cavity contracts.Your lungs deflate and became smaller. Now,the air goes up through your bronchioles,bronchi,windpipe and larynx and leaves the body through your nostrils.

Gas exchange:
In your lungs you have alveoli. It is here that gas exchange occurs. During this process, oxygen from the outside air passes into your blood and carbon dioxide which is in the blood passes to your lungs and leaves your body.

This parts travel around the body by:
 1.Air enters the body through the notrils.
 2.The air travels down through;
    The larynx,the windpipe, the brochi and the bronchioles, and finally reaches the lungs.
 3.Gas exchange takes place in the alveoli.


This are the parts of the repiratory system:

Fun facts
1. The right lung is  larger than the left.
2. Hairs in the nose help to clean the air we breathe and warm it.
3. The highest  "sneeze speed" is 165 km per hour.
4. The capillaries in the lungs would extend 1,600 kilometres if placed end to end.
5. We lose half a litre of water a day through breathing. 
6. A person at rest usually breathes between 12 and 15 times a minute. 
7. Is faster in children and women than in men,

circulatory system

circulatory system 

The circulatory system is the most important system because is the only one that works wiht the all systems.

The circulatory system is in charge of transporting the oxygen and the nutrients to the cells and to eliminate its wastes.

The circulatory system consists of heart,blood and blood vessels.

                                         Heart:
     The heart is the principal organ of the            system.Inside the heart there are four              cavities: two atria and two ventricle.              The heart pumped the blood 
     to pass it to the whole 
     body. 
      

Blood:

   In the blood they are three types blood cells:


   Red blood cells: 

   They transport  oxygen and carbon 

   dioxide.

    
     White blood cells: 
    They protect the body by capturing
    bacteria and viruses.




  Platelets:
   Close the wounds to stop 
   bleeding. 



 Blood vessels:
 Enter the body there are three  types of blood vessels.

 Capillaries:

It is the smallest vein in the blood vessels.

Arteries:
They carry oxygenated 
blood.

Veins: 
Carries waste from the blood.

CIRCULATORY SYSTEM

CIRCULATORY SYSTEM
Is a organ that permits blood to circulate and transport nutrients, oxygen, carbon dioxide and blood cells.
Blood is consisting:red blood cell, white blood cells ,and platelets that is circulated by the heart through the vertebrate vascular system , carring oxygen and nutrients from all the body.

RED BLOOD CELLS                                        tranport oxygen through the body . we need  the red blood cells to survive.  

WHITE BLOOD CELLS                                  there are cells that are protecting your body.

PLATELETS                                                          preven and stop your bleeding is vitally needed.

RESPIRATORY SYSTEM

Introduction

The respiratory system is vital in keeping you alive. It is a complex system that brings needed oxygen into your body and then take unwanted carbon dioxide out of your body.

Oxygen is the key factor needed for your body cells for life funciona. All of your cells make use of the oxygen and then give off waste gas in the form of carbon dioxide.

How the Respiratory System Works?

The respiratory system’s primary function is to breathe in air, absorb oxygen into the bloodstream, and breathe out carbon dioxide.

Air comes into the body through the nose or mouth, and enters the airways. Airways are the tubes that carry air into our lungs. As they branch out, they become smaller and smaller, and eventually connect to small air sacs where fresh oxygen from the air is exchanged for carbon dioxide in the blood. This oxygen is then taken through the blood to the rest of your body, where it is used to produce energy.

Main parts of the Respiratory System and their Function

Nasal cavity: Cleans, warms, and moiistens the air.

Pharynx: Only passageway that air and food travels through at the same time.

Larynx: Also known as the voice box, as air goes through te vocal cords, it makes a vibration, making sounds. 

Epiglottis: Flap of tissue that closes the airway from the pharynx when we swallow. This allows foos to move to the esophagus and prevents foos from moving to the lungs.

Trachea: Main airway for air that leads to the chest. It is lines with cartilage to prevent it from collapsing.

Bronchi: A division of the trachea that branches off bronchioles and then the lungs.

Bronchioles: Smaller airways that branch off from the bronchi.

Lungs: Masses of clustered alveoli. They are the two main organs of the respiratory system.

Alveoly: Clusteres of tiny air sacs that make up the lungs.

Diaphragm: A thin muscle that moves up adn down to hepl us breathe. When it moves up, air pressure increases as the chest cavity becomes smaller. Air eventually moves out. The opposite happens when we inhale.

Diseases of the Respiratory System

Diseases of the respiratory system fall into two categories:

• Viruses such as inluenza, bacterial pneumonia and the new enterovirus respiratory virus that has been diagnosed in children.
• Chronic diseases, such as asthma and chronic obstructive pulmonary disease.

CIRCULATORY SYSTEM

CIRCULATION

The circulatory system transport nutrients and oxygen through to the cells. It also helps them to get rid of waste products.

1.Blood

Blood consists of plasma and blood cells.

·Plasma: is the fluid wich your blood cells float in. It also carries the nutrients and waste products.

·Blood cells: In a drop of blood there´re different types of blood cells:

 1. Red blood cells: 

They transport oxygen and carbon dioxide.











2. Platelets:                                                
They heal wounds and stop you bleeding.                                                






3. White blood cells:

They defend your body from microorganisms and viruses.







2.Blood vessels
Inside your body there are three types of blood vessels.

 
       











 3. The heart        
The hear is a muscular organ with four chambers: two atria and two ventricels. They comunicate through valves. The heart contracts and expands to push blood around the body through beating. Each beat has two phases:
·Systole: The heart contracts and sense blood to the arteries.
·Diastole: the hear relaxes and blood enters from the veins.
       



4. Your blood moves around your body
Blood circulation is te journey that your blood takes around the body. This journey is divided into two routes:
·Pulmonary circulaton: This is the route that your body takes from the hear to the lungs, and back again.
·General circulation: This is the route your blood takes around the rest of your body.

DIGESTIVE SYSTEM

The digestive system transforms the food we eat into nutrients an passes them to the blood.

It also expels the undigested food out of the body as faeces.

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body.

 The digestive system is divided into parts: pharynx, oesophagus, liver, stomach, pancreas, small intestine, large intestine, rectum, and anus.

Fun facts

1. An adult esophagus ranges from 10 to 14 inches in length, and 1 inch in diameter.

2. We make 1 to 3 pints of saliva a day.

3. Muscles contract in waves to move the food down the oesophagus. This means that food would get to a person's stomach, even if they were standing on their head

4. It takes your mouth, esophagus, stomach, small intestine, large intestine, gallbladder, pancreas and liver just to digest a glass of milk..

5. An adults stomach can hold approximately 1.5 liters of material.

6. The average male will eat about 50 tons of food during his lifetime in order to sustain a weight of 150 pounds.

7. Within the colon, a typical person harbors more than 400 distinct species of bacteria

8. The liver is the largest organ in the body and performs more than 500 functions.

9. The small intestine (pronounced in-test-in) is a long tube about 1 and a half to 2 inches around, and about 22 feet long.

11. Food stays in your stomach for 2 to 3 hours.
