A narrow opening through which a liquid flows is often referred to as a "narrow channel" or "orifice." This type of passage is designed to control the flow rate and direction of the liquid, commonly used in various applications like Plumbing, engineering, and fluid dynamics. The size and shape of the opening can significantly affect the liquid's velocity and pressure as it passes through.

One way to measure viscosity without using a viscometer is by observing the flow of a liquid. A more viscous liquid will flow more slowly than a less viscous liquid. This can be done by pouring the liquid and observing how quickly it flows. Another method is to measure the time it takes for a liquid to flow through a narrow tube or small opening. The longer it takes, the higher the viscosity.

The narrow tubes that urine flows through are called ureters. Each kidney is connected to the bladder by a ureter, which transports urine formed in the kidneys to the bladder for storage before it is expelled from the body.
