Anatomy of the Blood Vessels

Everything to know about the anatomy of blood vessels
Describe the pulmonary and systemic circulation.
Pulmonary circulation carries blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart. Systemic circulation is the larger circulation; it provides the blood supply to the rest of the body.
Describe the structure and function of arteries.
Arteries: thick wall with three layers-tunica intima(endothelial lining), tunica media(elastiec tissue and smooth muscle), and tunica adventitia(connective tissue) function; conductance vessels because they carry blood from the heart to the arterioles.
Describe the structure and function of capillaries.
Capillaries: Layer of endothelium. function; called the exchange vessels because nutrients, gases, and waste exchange between the blood and interstital fluid.
Describe the structure and function of veins.
Three layers (intima, media, and adventitia), but thinner and less elastic than an artey; veins contain valves. function; collect and return blood from tissues to the heart, hold and store blood.
List the three layers of tissue found in artieries and veins.
Intima, media, and adventitia.
Explain the functions of conductance, resistance, exchange, and capacitance vessels.
Conductance vessel is when the primary function of the large arteries is to conduct blood from the heart to the arterioles. Resistance vessels is because their effect on resistance. Capacitance vessles is when the veins store blood.
List the major arteries of the systemic circulation that are branches of the ascending aorta, aortic arch, and descending aorta.
Right and left coronary arteries, the brachiocephalic artery, left common carotid artery, left and right subclavian arteries, and the intercostal arteries.
List the major veins of the systemic circulation.
Venae Cavae
Describe the following special circulations: blood supply to the head and brain, and hepatic circulation.
Carotid arteries supply the head and brain and jugular veins drain the brain and head. Hepatic circulation is when the portal vein carries blood from the organs of digestion to the liver.
