A ring-shaped molecule is a molecule that connects its ends together to form a closed loop structure. These molecules are also known as cyclic molecules and can exhibit unique properties due to the ring structure, such as increased stability or reactivity compared to their linear counterparts. Examples of ring-shaped molecules include cyclic compounds like cyclohexane or benzene.
Cricoid cartilage :D

Precapillary sphincters control blood flow into capillaries, regulating the distribution of oxygen and nutrients to tissues based on demand. Constriction of these sphincters reduces blood flow while relaxation increases blood flow, ensuring efficient delivery of resources to active tissues.
