l) 7-12 g m/m²

Introduction:

Vascular resistance is the resistance required by the blood to flow through the circulatory system. There are two types of vascular resistances- total peripheral resistance and pulmonary vascular resistance. The pulmonary vascular resistance can be measured in dynes $\times$ sec $\times$ cm^-5 (where sec represents seconds and cm represents centimeters).
