veins have valves. y
A cross section of a vein shows a thinner wall than that of the artery, and shows one-way valves. A cross section of an artery shows a thicker, more muscular wall and no valves.
The radial artery is the one that is used to take a pulse at the wrist.
Radial artery
Arteries are the strongest since it carries high pressured plasma away from the pumping heart. Veins carry blood from the body towards the heart; it has valves to ensures to only flow in one direction, towards the heart. There is only one vein in the body that does not contain valves, which is near the heart called the vena cava. Capillaries are connected from the veins to the body's cells, which is the weakest in strengh.
There are four total valves in the heart. The Mitral and Tricuspid in the atria and ventricles The Aortic between the Aorta and left ventricle The Pulmonary between the Pulmonary artery and right ventricle

Valves cause our blood to flow in one direction, thus preventing regurgitation of blood.
Another name for the pulmonary valve is the pulmonic valve. It is one of the four heart valves and is located between the right ventricle and the pulmonary artery, regulating blood flow from the heart to the lungs for oxygenation.
Radial artery

Radial artery
No arteries do not contain valves since there is enough pressure from the heart to force blood through these vessels without significant backflow between contractions.

There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.

Veins contain valves preventing blood from circulating backwards.
