where blood leaves Heart

DUB
The _______________ contract when the heart's electrical impulse reaches the Purkinje fibers
ventricles
The SA node cause the ___________ to contract
atria
Carotid Artery
Major artery that carries blood to the brain
Systemic or General Circulation
Blood travels from the heart to the tissues and cells
Small veins
venules

Swelling
Artherosclerosis
Develops when fatty deposits form on the walls of the arteries
Embolism
traveling blood clot
__________ permit blood to flow in one direction of the heart
valves

hypotension
may be a cause for syncope (fainting)
less that 100/60
symptom can be vertigo or dizziness when suddenly getting up
Aneurysm
abnormal condition characterized by a protrusion in the wall of an artery
Electrical Impulse Activity of the Heart
Atria contract > AV Node > Bundle of His > Purkinje Fibers > Ventricles contract
Arteriosclerosis
develops when arterial walls thicken and lose elastically
Oxygen and Carbon Dioxide are exchanged in these blood vessels
Capillaries
Veins collapse easily when not filled with blood?
True
