Adaptations of the artery

HideShow resource information


They cary oxygentated blood (except for the pulmonary artery and umbilical arteries) away from the heart. The arterial system is under the highest pressure in the circulatory system. The arterial pressure peaks at systole when blood fills the atria. The pressure variation in the arteries causes the pulse observable in major artery that reflect heart activity. Blood pressure and artheroma (an artheromous plaque in the walls of the artery is a build up of cell debris that have uptaken lipids and contain some fibrous connective tissue) are some pathological conditions that can affect the heart. As the arterial system deviates further into the body they divide into smaller components known as arterioles
