Flashcards in Blood Vessels Deck (42):
Blood from the heart to the body
Blood from the body to the heart
Smallest arterial vessels.
Where vnous return starts at the capillary level... Very small veins... Deoxygenated blood!
Inner lining of blood vessels (endothelium)
Middle layer of the vessel. Includes smooth muscle portion and is the thickest of layers.
Outer layer of the vessel.
Artery that supplies the heart muscle (myocardium)
Right coronary artery
Devides into branches on the right side of heart.
The branches supply the blood flow to RIGHT ATRIUM and RIGHT VENTRICLE, and under (inferior portion) of the LEFT VENTRICLE.
It also supplied blood to the conduction system(SINUS AND AV NODES)
Left coronary artery
Divides into two branches.
Supplies blood to most of the left ventricle, intraventricular septum, and sometimes the AV node.
Two branches of the LEFT coronary artery
Left Anterior Descending
Circumflex Coronary Arteries
Arises from the lest ventricle. Has two branches (left and right main coronary arteries)
Three major arteries arise from the aortic arch:
left common carotid artery
left subclavian artery.
Longest portion of the aorta.
Consists of Thoracic and Abdominal aorta.
First vessel to branch from the aorta
Divides into right subclavian and right carotid.
Point of division at which the common carotid artery branches into the internal and external carotid.
Superior to the carotid bifurcation.... Regulates blood pressure
Calcium deposits in the arterial walls.
Hardens the arteries.
Reduction in blood flow.
Part of coronary artery disease
Carries blood to the lungs
Carries blood to the body (system)
Arises from the left ventricle and consists of the right and left coronary arteries. CIRCULATION TO THE HEART MUSCLE
Where the carotid divides into the internal and external carotids
In the Carotid Bifurcation. Important in regulating blood pressure.
Where the left and right vertebral arteries meet.
Mass of nerve fibers at the end of the medulla oblongata
Part of the brain that is dorsal to the Pons and is responsible for coordination and balance.
Where the arotid arteries enter the cranial vault
Supply blood to the large portions of the brain cortex.
Circle of Willis
Interconnection of arteries delivering blood to the brain.
Arteries in the hand from the radial artery and ulnar artery.
Visceral Arteries ]
Supply blood to the organs
Supply blood to the walls.
While and Cool fingertips from stress or cold exposure.
big artery by the femur
Dorsalis Pedis Artery
Pedal pulse spot. artery on the superior portion of the foot.
Blockage of arterial blood flow to the digestive system.
Drain blood from the brain into the internal jugular vein.
Hepatic Portal System
Part of the venous system. Drains blood from the liver, stomach, intestines, and spleen.
Inflammation of superficial and small veins
