Question

Which of the following option represents the correct blood flow pathway in pulmonary circulation?

• A. $Right \, ventricle \, \rightarrow _{v e i n}^{P u l m o n a r y} \, Lungs \, \rightarrow _{a r t e r y}^{P u l m o n a r y} \, Left \, atrium$
• B. $Right \, ventricle \, \rightarrow _{a r t e r y}^{P u l m o n a r y} \, Lungs \, \rightarrow _{v e i n}^{P u l m o n a r y} \, Left \, atrium$
• C. $Left \, ventricle \, \rightarrow _{v e i n}^{P u l m o n a r y} \, Lungs \, \rightarrow _{a r t e r y}^{P u l m o n a r y} \, Right \, atrium$
• D. $Left \, ventricle \, \rightarrow _{a r t e r y}^{P u l m o n a r y} \, Lungs \, \rightarrow _{v e i n}^{P u l m o n a r y} \, Right \, atrium$
