véredény

Veredeny is a Hungarian term that translates to "blood vessel" in English. It refers to the anatomical structures that form the circulatory system, responsible for transporting blood throughout the body. These vessels are broadly categorized into arteries, veins, and capillaries.

Arteries are thick-walled vessels that carry oxygenated blood away from the heart. They are subject to high pressure, hence their robust structure. The largest artery is the aorta.

Veins, conversely, carry deoxygenated blood back to the heart. They have thinner walls than arteries and often contain valves to prevent the backflow of blood, especially in limbs where blood must travel against gravity. The vena cavae are the largest veins.

Capillaries are the smallest and most numerous blood vessels, forming a network that connects arteries and veins. Their thin walls facilitate the exchange of oxygen, carbon dioxide, nutrients, and waste products between the blood and the body's tissues.

The collective network of veredények, along with the heart, constitutes the cardiovascular system. This system is vital for sustaining life by ensuring that all cells receive the necessary oxygen and nutrients and that waste products are efficiently removed. Conditions affecting veredények, such as atherosclerosis or varicose veins, are common medical concerns.
