3. greater than 1
4. 1

Q. Choose the correct pathway for systemic circulation.

1. Right auricle → Left ventricle → Aorta → Tissues → Veins
2. Right ventricle → Pulmonary aorta → Tissues → Pulmonary veins → Left auricle
3. Left ventricle → Aorta → Arteries → Tissues → Veins → Right atrium
4. Left auricle → Left ventricle → Pulmonary aorta → Tissues → Right auricle

Q. What do you understand by the term respiratory quotient?

1. Ratio of volume of $C{O}_2$ evolved to the volume of $O_2$ consumed in respiration
2. Ratio of volume of $O_2$ evolved to the volume of $C{O}_2$ consumed in respiration
3. Ratio of volume of $O_2$ consumed to the volume of $C{O}_2$ evolved in respiration
4. Ratio of volume of $C{O}_2$ consumed to the volume of $O_2$ evolved in respiration

Q. Match the items given in column I with those in column II and select the correct option given below:
