Final answer:
The primary reliance of this bandage is the elastic tertiary layer, which provides stretch and flexibility to the bandage.
Step-by-step explanation:
The primary reliance of this bandage is the elastic tertiary layer. The elastic tertiary layer provides stretch and flexibility to the bandage, allowing it to conform to the shape of the body and provide a snug fit. This helps to secure the bandage in place and provide support to the injured area. The elastic tertiary layer also helps to apply gentle pressure to the injured area, which can help reduce swelling and improve blood circulation.
