CellsTissueOrganSystemsOrganism

Prepares food (nutrients) for absorption into the blood

How are the two types of digestion different?

Mechanical digestion (chewing)

Chemical digestion (enzymes)

What is the function of the digestive system

What is the function of the Respiratory System?

Takes in oxygen to make energy

Removes carbon dioxide

Where does oxygen & carbon dioxide exchange tale place?

Alveoli is the site of gas exchange in the lungs

What is the function of the Circulatory System?

Transports materials throughout the body.

What are the components of blood?

Red Blood cells – carry oxygen & CO2

White Blood cells – Fight infections

Platelets – Clot blood (stop bleeding)

Which organ pumps the blood?

Heart – pumps the blood

Name the 3 types of blood vessels?

Arteries, Veins, Capillaries

Which blood vessels carry blood away from the heart? Toward the heart?

Arteries – carries blood Away from heart

Veins – carries blood to the heart

In which blood vessels does gas and nutrient exchange take place?

Capillaries – smallest – gas & nutrient exchange takes place with the cell

What is the function of the Immune System?

To help protect the body against microorganisms

What are the parts of the immune system? Skin, mucous, acid, white blood cells, antibodies

What is a vaccine and why are they important? Vaccinations- weak virus, helps your body

produce antibodies
