Circulatory and Respiratory Systems

Circulatory System

• 2 functions1. Blood delivers nutrients (food)

and oxygen to cells so they can function.

Veins and arteries in the head and hand

2. Blood removes waste products, like carbon dioxide, from cells.

Respiratory System

• 1 Function– Supplies body

with fresh oxygen and removes carbon dioxide

Both systems work together

Pulmonary and Systemic Circulation

• The flow of blood to the heart (pulmonary) then lungs, back to the heart, then out to the rest of the body (systemic)

Start with a red blood cell, sugar, and CO2 card in the right ventricle.

1. Blood with CO2 exits the right side of the heart

Move the red blood cell, CO2, and sugar out of the heart into the pulmonary vein

2. Blood enters lungs, drops off CO2, and picks up oxygen

Move the blood cell to the lungs, drop off the CO2 and pick up an oxygen (O2) card

3. Blood returns to the left side of the heart

Move the red blood cell, sugar, and oxygen (O2) into the left atrium.

4. Oxygen rich blood is pumped out of the heart to the rest of the

body

Move the red blood cell, sugar, and oxygen to the left ventricle, then out the aorta.

5. Blood exchanges oxygen for wastes with other cells in the body

a. Oxygen rich blood in

b. Oxygen dropped offc. Wastes picked up

d. Blood returns to heart

Move the blood cell into the systemic section (body) and drop off the oxygen and sugar. Pick up waste material.

6. Oxygen poor blood returns in veins back to the right side of the

heart

Move the red blood cell and waste material into the right atrium
