Blood Vessels And Circulation In this video, dr mike explains the two different types of circulation and how arteries, arterioles, capillaries, venules and veins are all different. he out. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. these layers surround the lumen, the hollow interior through which blood flows. 2. oxygenated blood flows away from the heart through arteries. the left ventricle of the heart pumps oxygenated blood into the aorta.
Understanding Circulation And Blood Vessels вђ Bilarasa The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. the heart then sends oxygenated blood through arteries to the rest of the body. the veins carry oxygen poor blood back to the heart to start the circulation process over. your circulatory system is critical to healthy organs, muscles and tissues. Your body contains about 60,000 miles of blood vessels. there are three types of blood vessels: arteries carry blood away from your heart. veins carry blood back toward your heart. capillaries, the smallest blood vessels, connect arteries and veins. advertisement. The circulatory system, also known as the cardiovascular system, is a simple loop which starts, and ends, with your heart. it is a closed system, meaning blood does not enter or leave the system during its journey from your heart to your body and back again. in such a system, a continuous flow of the same liquid can be pumped through the loop. The circulatory system works thanks to constant pressure from the heart and valves throughout the body. this pressure ensures that veins carry blood to the heart and arteries transport it away.

Thrombus formation and embolisation can also occur. aneurysms can rupture, leading to significant blood loss depending on where they occur. particularly lethal sites of aneurysm formation are in the abdominal aorta, the circle of willis in cerebral circulation, and in the renal vessels. varices occur where blood vessels become enlarged and. Your circulatory system is vital to your survival. its function is to distribute blood and other nutrients to all your body’s organs and tissues. the small blood vessels, called capillaries.
