four chambered, hollow, muscular organ approximately the size of your fist, located in the superior surface of the diaphragm, left of the midline, anterior to the vertebral column, posterior to the sternum
Functions of the Heart
Generates blood pressure 2. Separates pulmonary and systemic circulations 3. ensures one way flow 4. Regulates blood supply
Blood Vessels
closed network of tubes including arteries, capillaries, and veins; tunica intima, tunica media, tunica adventitia
Arteries
distributing channel with thick walled tubes, elastic fibers, and circular smooth muscle; carry blood AWAY from the heart (oxygenated); elastic (aorta), muscular (renal, radial), arterioles (terminal arterioles)
Capillaries
microscopic blood vessels, one cell thick, serves the respiratory system, connect to arteries and veins, continuous and fenestrated
Veins
blood vessels that carry blood BACK to the heart, one-way valves, large irregular lumen
Sinusoids
large, irregular vascular space
Coronary Circulation
circulation of blood within the heart
Pulmonary Circulation
flow of blood between the heart and lungs
Systemic Circulation
flow of blood between the heart and cells of the body
Portal Circulation
