What is the main artery of the lower arm that is felt at the wrist?

The radial artery is the main artery of the lower arm felt at the wrist. It runs along the radial side (thumb side) of the forearm and is easily accessible at the wrist, making it a common site for checking the pulse. This artery is important for both medical assessments and emergency situations, as it provides vital information about the cardiovascular status of an individual.

In contrast, the aorta is the body's largest artery, responsible for transporting blood from the heart to the rest of the body, but it is not located in the lower arm or accessible at the wrist. The femoral artery is located in the thigh and is the main artery of the leg, while the subclavian artery supplies blood to the arms and upper body but is situated farther up in the chest area, not in the wrist region. Understanding the specific locations and roles of these arteries is essential for any healthcare provider.
