Question

Which valves do blood vessels have?

Answer 1

Blood vessels have two types of valves:

1. Venous valves: These are one-way valves found in veins that prevent blood from flowing backward. They help to ensure that blood is directed towards the heart and does not pool in the veins.

2. Cardiac valves: These are found in the heart and direct the flow of blood through the heart and into the blood vessels. They include the mitral valve, tricuspid valve, pulmonary valve, and aortic valve.
