1. RESPIRATORY SYSTEM

Through the respiratory system, living

things take the oxygen from the air and

eliminate carbon dioxide.

• Oxygen is very important for living

things to live.

• Carbon dioxide, on the contrary, is not

necessary for our health, and our body

eliminates it.

1.1. PARTS OF THE RESPIRATORY SYSTEM:

The respiratory system has two main parts: airway and

lungs.

• Airway: Ducts through which air enters and leaves

our body.They consists of: notrils, pharynx, larynx, thrachea

and bronchi. Bronchi are divided into bronchioles.

• Lungs: The lungs are two spongy and pink organs.

The ribcage protects them. In the lungs gas exchange

occurs: our respiratory system takes air and removes

carbon dioxide.

Lungs are spongy and red organs

• Through the respiratory system, living things take the oxygen from the

air and eliminate carbon dioxide.

• The respiratory system has two main parts: airway and lungs.

• There are two main movements of breathing: inhalation and

exhalation.

1.2. HOW WE BREATHE

When we breathe:

1.- The air enters the nose trough the notrils.

2.- The air goes to the pharinx and then to the

larynx.

3.- After that, the air reaches the trachea. It is

divided into two branchi. Both are located into the

lungs.

1.3.RESPIRATORY MOVEMENTS:

There are two main movements of breathing:

inhalation and exhalation.

• Inhalation: Air enters the lung. The lungs

and rib cage expand.

• Exhalation: The air comes out. The lungs

are deflated.



By MBLS and MACS 4

ACTIVITIES

1. Look at this photo and talk about it.

2. Label the respiratory system.



By MBLS and MACS 5

3. Read and choose true or false. Afeter say.

TRUE FALSE

1.- Through the respiratory system, living things take the oxygen from the air and eliminate carbon dioxide.

2.- Oxigen is not very important for living things to live.

3.- In the lungs gas exchange occurs.

4.- The respiratory system has two main parts: airway and lungs.

5.- The air enters the nose trough the pharinx.

6.- In the inhalation movement air enters the lung. The lungs and rib cage expand.

4. Read and order the sentences:

• The air reaches the trachea. It is divided into two branchi. Both are located

into the lungs ______

• The air enters the nose trough the notrils. ______

• The air goes to the pharinx and then to the larynx. ______

5. Write and say the correct respiratory movement.

2. EXCRETORY SYSTEM

Excretion is the process through which

we clean our blood and eliminate waste from

our body. So the body expels the subtances that

our body does not need.

2.1. PARTS OF THE EXCRETORY SYSTEM

The excretory system consists of:

• Kidneys: They are located in the

abdomen. They are bean-shaped and dark red.

• Bladder: Urine flows into the bladder

before being expelled.

• Ureters: Two tubes that connect the

kidneys to the bladder.

• Urethra: The tube that connects the

bladder to the outside.



By MBLS and MACS 7

2.1.1. KIDNEYS

All the blood in our body reaches the

kidneys.The kidneys filter blood and eliminate

waste products as urine. 95% of urine is

water.

Urine leaves the kidneys, travels

through the ureters and reaches the bladder.

There is expelled through the urethra.

2.1.2. SWEAT AND SWEAT GLANDS

Sweat is a liquid that appears when it´s

hot or when we practice physical exercise.

Sweat contains water, mineral salts and waste

products

Sweat glands form sweat and they are

situated in the skin. The sweat glands removes

waste substances, so they are involved in the

excretory system.



By MBLS and MACS 8

ACTIVITIES

6. Look at this photo and talk about it.

• Excretion is the process through which we clean our blood and eliminate

waste from our body.

• The excretory system consists of kidneys, bladder, ureter and urethra.

• The sweat glands removes waste substances, so they are involved in

the excretory system

eliminate waste from our ________. So the body expels the ___________

that our body does not __________.

3. CIRCULATORY SYSTEM

To perform the function of nutrition blood

carries nutrients, oxygen and waste products.

The circulatory system consists of blood,

blood vessels and heart.



By MBLS and MACS 11

3.1. BLOOD

Blood is the only tissue of our body that is liquid. It

transports nutrients, oxygen, carbon dioxide and waste products.

Blood is made of a liquid called plasma and blood cells: red

cells, white cells and platelets.

• Red cells: Red cells carry oxygen and give blood its colour.

• White cells: White cells defend us from disease.

• Platelets: Platelets plug up blood vessels after an injury.

This process is called coagulation.

3.2. BLOOD VESSELS

Blood vessels are types of tubes through which

blood circulates.

There are three types: arteries, veins and capillaries.

• Arteries: The arteries carry blood from the heart.

• Veins: The veins carry blood towards the heart.

• Capillaries: The capillaries connect the arteries

and veins. They carry blood to our organs.



By MBLS and MACS 12

CAPILLARY ARTERY

VEIN



By MBLS and MACS 13

3.3. HEART

The Heart is a muscular organ that

pumps blood throughout the body.

The heart works all our lives, it

doesn´t stop.

It is divided into two halves: right and left,

which are divided by an atrium and a

ventricle.

Blood flows from the atria to the

ventricles thanks to valves.

When we play a sport our heart beats faster

ANATOMY

3.4. BLOOD CIRCULATION

Circulation is the journey that makes the blood all around the

body through blood vessels.

The heart pumps blood. The heartbeat has two phases:

• Systole: The heart contracts. The blood leaves the heart through

the arteries.

• Diastole: The heart relaxes. The blood, which is carried by the

veins, enters the heart.



By MBLS and MACS 14

3.5. PULMONARY CIRCULATION

It is the journey that makes the blood into the lungs. Thus, the blood picks

up oxygen and removes carbon dioxide.

1. The blood flows from right ventricle to the pulmonary arteries.

2. The blood picks up oxygen in the lungs.

3. The blood returns to the left atrium through the pulmonary veins.



By MBLS and MACS 15

3.6. GENERAL CIRCULATION

The journey that makes the blood throughout

the body. Blood carries oxygen to all body parts.

1.The blood leaves the left ventricle by the aorta.

2.The blood goes through all the organs of the

body carrying oxygen and nutrients.

3.The blood returns to the right atrium through the

vena cava.

Veins carry blood back to the heart.

The heart is a muscular organ that pumps to every part

of our body

Arteries carry blood and nutrients from our heart to all parts

of our body.

Capillaries connect the arteries and veins. They carry

blood to our organs.
