Nutrition
• It consists on taking in nutrients from
food (digestive system), getting oxygen
from air (respiratory system),
transport the oxygen and nutrients to
the rest of the body (circulatory
system) and clean the waste from the
blood (excretory system)

Circulatory System • The Circulatory System deliveries blood
with nutrients and oxygen to the body and collects waste and carbon dioxide from the body.

The Digestive System • In the mouth (1) we chew the food with our teeth and mix it with the
saliva (2).
• Then, the food passes through the pharynx (3) to the esophagus (4).
• The food goes to the stomach (5) and we mix the food with the
stomach juices.
• Then, the food paste passes to the small intestine (6). There, we mix
the paste with the bilis, the pancreatic juices and the intestinal juices.
The nutrients are absorbed into the blood.
• The food paste, the waste, that we don´t need goes to the large
intestine (7). The water is absorbed and we make poop that goes out
through the anus (8).

Mouth We chew the food with our teeth
Salivary Glands We mix the food with the saliva
Pharynx It connects the mouth and nose with
the esophagus
Esophagus It connects the pharynx to the stomach
Stomach We mix the food with the stomach
juices and break it to a paste
Liver It produces a digestive juice, the bile
Pancreas It produces the pancreatic juice.
Small intestine We mix the paste with the intestinal
juices, the bile and the pancreatic juice.
The nutrients are absorbed
Large intestine The water is absorbed and turns the
waste paste into poop
Anus The poop is released

The Respiratory System
• We breathe in air through the nose (1) and mouth
(2).
• Air travels down the trachea or windpipe (3) and
through the bronchi (4) to go to the lungs (5).
• In the lungs we take in oxygen from the air and
release carbon dioxide.
• The oxygen is passed to the blood
