What are the two main circulatory systems in humans?
Pulmonary
Systemic
What is the route of the pulmonary circulatory system?
From the heart
To the lungs
And back
What happens in the pulmonary system?
Blood is oxygenated through diffusion in the lungs
Which blood vessels are involved in the pulmonary system?
Pulmonary arteries
Pulmonary veins
What route does the systemic circulatory system follow?
From the heart
To the rest of the body
And back
What happens during the systemic circulatory system?
Oxygen is passed to the cells
Carbon dioxide is collected from the cells
Which blood vessels are involved in the systemic circulatory system?
Aorta Arterioles Capillaries Venules Vena cavae
