An arteriole is one of the small branches of an artery, especially one which connects with capillaries.

Arteries divide into smaller vessels called Arteriols. Arteriols subdivide into even smaller vessels called capillaries, where oxygen, nutrients, hormones are delivered to the tissues of the body. Waste products are also picked up by capillaries and delivered to venules which grow into larger vessels called veins. Veins deliver deoxygenated blood back to the heart.
The arteries (and arterioles) still carry the pulsing from the heart. By the time the blood flow reaches the capillaries and the veins, it is lost. This helps to keep the blood flowing in the right direction.

There are mainly two parts in Cardiovascular system. 1. Heart. & 2.Blood vessels. Blood vessels contains arterial system(aorta-artery-arteriols-capillary) & Venous system (venacava-vein-venules-capillary)

An arteriole is like a 'mini artery' So it has a very similar function to an artery. Allows exchange of gasses (carbon dioxide and oxygen) and nutrients (waste products like urea and substances like glucose)
you find non return valves inside the heart, lymph and veines, avoiding fluids from flowing backwards > [veinous blood in veines and heart, oxygenated blood in the heart]. Lymph vessels have valves also. The portal vein though contains no valves. All arteries including arteriols and capillaries have no valves.
The diameter of arterioles is primarily controlled by the smooth muscle in their walls, which can contract or relax in response to various signals. Key regulators include local factors such as oxygen levels, carbon dioxide levels, and pH, as well as systemic factors like hormones (e.g., epinephrine) and neural input from the sympathetic nervous system. This regulation allows for fine-tuning of blood flow and resistance within the circulatory system, adapting to the body's metabolic demands.
