The human body vital functions

The human body performs the three vital functions:

- Nutrition to get energy to grow and survive.

- Interaction to feel what happen around and inside us and respond.

- Reproduction to create new living organisms.

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)

Nutrition Systems

Digestive system

• The Digestive System breaks down the food into nutrients.

Respiratory System

• The Respiratory System takes in oxygen and release carbon dioxide.

Circulatory System • The Circulatory System deliveries blood

with nutrients and oxygen to the body and collects waste and carbon dioxide from the body.

Excretory System

• Excretory System cleans blood and makes pee.

The Digestive System

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

Mouth We breathe in air through the

mouth

Nose We breathe in air through the nose

Trachea or windpipe It connects the mouth and nose

with the bronchi

Bronchi It takes the air into the lungs

Lungs We take in oxygen and release

carbon dioxide. The oxygen passes

into the blood.
