Q. Which of the following sequences is truly a systemic circulation pathway?
A) Right ventricle $\rightarrow$ Pulmonary aorta $\rightarrow$ Tissues $\rightarrow$ Pulmonary veins $\rightarrow$ Left auricle
B) Right auricle $\rightarrow$ Left ventricle $\rightarrow$ Aorta $\rightarrow$ Tissues $\rightarrow$ Veins $\rightarrow$ Right auricle
C) Left auricle $\rightarrow$ Left ventricle $\rightarrow$ Pulmonary aorta $\rightarrow$ Tissues $\rightarrow$ Right auricle
D) Left auricle $\rightarrow$ Left ventricle $\rightarrow$ Pulmonary aorta $\rightarrow$ Arteries $\rightarrow$ Tissues $\rightarrow$ Veins $\rightarrow$ Right atrium
Explanation
The systemic circulation pathway is - Left auricle $\rightarrow$ Left ventricle $\rightarrow$ Pulmonary Aorta $\rightarrow$ arteries $\rightarrow$ tissues $\rightarrow$ Veins right atrium.
