The cardiovascular system is one big circuit - veins carry deoxygenated blood from the body towards the heart, where it will be pumped to the lungs and throughout the body again.
Human veins are categorized into several major groups, with the most notable being the superior and inferior vena cava, which return deoxygenated blood to the heart. Other important veins include the jugular veins (draining the head and neck), the subclavian veins (from the arms), and the femoral veins (from the legs). Additionally, the pulmonary veins carry oxygenated blood from the lungs to the heart. Each region of the body has a complex network of smaller veins that contribute to overall circulation.
The areas supplied by the carotid artery are primarily drained by the internal jugular vein and the external jugular vein. The internal jugular vein collects blood from the brain, face, and neck, while the external jugular vein drains the superficial structures of the head and neck. Additionally, smaller veins such as the facial vein and the thyroid veins also contribute to draining regions supplied by the carotid artery.
Carry oxygenated blood from the lungs to the left atrium so it can be transferred to the aorta which takes the blood to the head and arms.
The largest are the basilic and cephalic veins, with a smaller connecting vein called the median cubital vein; all important for being the most common vein used for drawing blood for lab tests in an office or hospital.

Pulsing veins are a sign of stress. I have the same thing. All over my head and face I can feel veins pulsing and can even see them pulsing at the temples and beneath my eyes.
Jugular veins
The jugular veins are veins that bring deoxygenated blood from the head back to the heart via the superior vena cava.
The superior vena cava (SVC) and inferior vena cava (IVC) are two large veins that transport deoxygenated blood back to the heart. The SVC collects blood from the upper body, including the head, neck, and arms, while the IVC gathers blood from the lower body, including the abdomen and legs. Both veins empty into the right atrium of the heart, playing a crucial role in the circulatory system by returning blood for reoxygenation. Their proper function is essential for maintaining effective blood circulation throughout the body.
