C) angiogram
D) keyhole
E) catheter

Accepted Answer

A stent is a fine tubular wire mesh that can be inserted into a coronary vessel during angioplasty to hold the vessel open and improve blood flow. Angioplasty is a medical procedure used to widen narrowed or blocked arteries. An angiogram is a diagnostic test that uses X-rays to provide detailed images of blood vessels in various parts of the body. A catheter is a thin, flexible tube that can be inserted into the body to deliver fluids or medications, or to remove waste products. A keyhole is a small opening, usually made in a surgical procedure, through which instruments or cameras can be inserted into the body. Therefore, the correct answer is B.
