Describe how blood moves through the
circulatory system.
Back to Jeopardy
Game Board
Circulatory System 500
Deoxygenated blood flows into the heart through the
inferior and superior vena cava. It enters the right
atrium and goes through the tricuspid valve into the
right ventricle. The blood then goes through the
pulmonary artery to the lungs. Oxygenated blood then
returns to the heart through the pulmonary veins into
the left atrium. It then travels through the mitral
valve into the left ventricle. From here it flows
through the aorta to the rest of the body.

The epiglottis is a flap of tissue that closes over the
trachea like a trapdoor; it makes sure food goes down
the esophagus to the stomach (not down the trachea
and into the lungs).

Describe how a molecule of oxygen travels
through the respiratory system.
Back to Jeopardy
Game Board
Respiratory System 500
A molecule of oxygen first enters through your nose or
mouth. Then, it goes down your pharynx/throat and into
your windpipe, also known as your trachea. After that,
the air molecule goes through the bronchi into your
right or left lung. As it travels through the bronchioles,
the carbon dioxide and oxygen are exchanged in the
grape-like sacs called alveoli.
