Final answer:
Factors affecting laminar flow include stenosis narrowing and turbulent blood flow, which can produce audible vibrations known as Korotkoff sounds.
Step-by-step explanation:
Laminar flow refers to the smooth flow of a fluid in layers that do not mix, while turbulence is characterized by eddies and swirls that mix the layers of the fluid together. Factors affecting laminar flow include stenosis narrowing, which can result in a reduction in the size of the opening and cause the fluid to slow down. Additionally, turbulent blood flow can produce audible vibrations known as Korotkoff sounds, which can be detected with a stethoscope.
