Digestive System
The human digestive system is a group of organs that extract nutrients from food and eliminate waste products. Food can take between 24 and 72 hours to pass through the system.

AUX. ORGANS
INTESTINES
copy
Mouth
We bite, crush and chew the food we eat with our teeth.
Saliva makes food easier to chew and swallow.
The tongue moves food around our mouth, forming a ball called a bolus.
copy
Oesophagus
When we swallow, the bollus passes into this long and flexible tube.
The epiglotis is a flap of cartilage at the top of the oesophagus that covers the trachea and stops food from going into the lungs.
copy
Stomach
Gastric juices break down the food and kill dangerous bacterias.
The muscular walls of the stomach mix the food and gastric juices to form a liquid called chyme.
Liver, pancreas and gallbladder
The chyme is mixed with bile from the liver and pancreatic juices from the pancreas.
These liquids break down the chyme into basic nutrients: proteins, fats, carbohydrates, vitamins and minerals.
copy
Intestines
copy
The nutrients pass through the thin walls of the small intestine and they are absorbed into the blood.
Food waste passes into large intestine, where extra water is absorbed back into the body. The rest of the waste leaves the body.
copy
Respiratory System
The respiratory system takes oxygen (O2) from the air and eliminates carbon dioxide (CO2) when we breath out. Our cells combine oxygen with other nutrients to make energy.
How our Respiratory System works?
copy
Respiration
The trachea goes down into the chest and then it divides into two smaller tubes called bronchi.
When we breathe in, the air enters our nose and mouth and it passes into a long tube called trachea.
Respiration
copy
Each bronchi is divided into smaller ones. The smallest ones are called bronchioles.
At the end of each bronchiole, there are tiny air sacs called alveoli. Each one is covered by many tiny capillaries that carry blood.
Gas Exchange
copy
Oxygen passes through the walls of the alveoli and into the blood. At the same time, carbon dioxide passes out of the blood and into the alveoli. When we breath out the carbon dioxide leaves the body through the nose and mouth.
Breath in and out
copy
Under the lungs, there is a large, flat muscle called the diaphragm.
Exhale Breath out
Inhale Breath in
The diaphragm goes up / expands. The ribcage contracts. Air flows out. The lungs deflate.
The diaphragm goes down / contracts. The ribcage expands. Fresh air flows in. The lungs inflate.

Circulatory System
The circulatory system carries blood around the body. Its main organ is the heart.

How our Circulatory System works?
Circulation
copy
In pulmonary circulation, the heart pumps deoxygenated blood to the lungs. Then the oxygenated blood flows back to the heart.
In systemic circulation, the heart pumps oxygenated blood to the rest of the body. Then the deoxygenated blood returns to the heart.
copy
Excretory System
The excretory system eliminates waste products. It includes the urinary system and the sweat glands.
SWEAT GLANDS
URINARY SYSTEM
Urinary System
copy
The urinary system helps to keep our blood clean and healthy. It removes waste products and then eliminate them from the body.
Sweat Glands
copy
Our body also eliminates waste through sweat glands in our skin. When we get hot, our sweat glands excrete sweat to cool us down. Sweat is a mixture of water, salt, and other minerals. Sweat leaves the body through tiny holes in the epidermis called pores.
