7
Question
Pulmonary artery
Answer
Carries deoxygenated blood from the right ventricle to the lungs
8
Question
Lungs (for gas exchange)

14
Question
The strongest contractions that help the blood move forward are from the ventricles
Answer
15
Question
Diastole
Answer
The relaxation phase of the heart when the ventricles are filling with blood
16
Question
Systole
Answer
The contraction phase of the heart when the ventricles pump blood
17
Question
Parietal
Answer
The outermost covering of the heart, connected to the cavity
18
Question
Visceral Pericardium
Answer
Cavity space between the parietal and the visceral layer of the heart
19
Question
Serous layer
Answer
Contains serous fluid which reduces friction between the layers to allow contractions

Question
Endocardium
Answer
Inner lining of the heart chambers

Question
Pulmonary circuit
Answer
Part of the circulatory system where gas exchange occurs in the lungs
