Chapter 2 - Circuits

Question 1

Where does the systemic circuit start and end?

Answer 1

The systemic starts in the left ventricle (aorta) and it ends in the right atrium (vena cava)

Question 2

Where does the pulmonary circuit start and end?

Answer 2

The pulmonary circuit starts in the right ventricle (pulmonary artery) and it ends in the left atrium (pulmonary vein)

Question 3

What is the only artery that carries deoxygenated blood?

Answer 3

Pulmonary artery

Question 4

What is the only vein that carries oxygentated blood?

Answer 4

Pulmonary vein

Question 5

What are the four steps of the systemic circuit?

Answer 5

1. comes from the aorta/L ventricular 2. carries O2 rich blood to body target etc. 3. exchange 4. takes CO2 back to vena cava/ R atrium

Question 6

What are the four steps of the pulmonary circuit?

Answer 6

1. comes from the pulmonary artery/R ventricular 2. goes to lungs 3. exchange 4. takes O2 rich blood back to pulmonary vein/ L atrium

Question 7

Where does O2 and nutrients get exchanged for CO2 and waste?

Answer 7

At body targets

Question 8

What happens at the lungs

Answer 8

CO2 gets exchanged for O2
