The valve between the right atrium and ventricle
Tricuspid
The pacemaker of the heart
SA node (Sinoatrial)
Great saphenous
Vein
Blockage of a blood vessel
Atherosclerosis
This hormone effects the beta receptors
Epinephrine
This valve allows blood to leave the left ventricle
Aortic valve
Inferior to the AV node (the next step)
Bundle of HIS
Takes oxygenated blood to the heart from the lungs
Vein
Blockage of a mesenteric artery can cause (specific name)
Mesenteric infarction
When alpha receptors are activated, this happens
Vasoconstriction
The innermost layer of a blood vessel

Cardiac cells have the ability to send electrical impulses, this is called
Conductivity
Muscle layer of the artery
The production of red blood cells is called
Erythropoiesis
Blood is made up of this

Artery
When hemoglobin is not broken down and recycled, jaundice can be seen. This unrecycled hemoglobin is called
Bilirubin
Cells that cause a histamine response
Mast cells
Depression between the right and left atria
Fossa ovalis
Ability of cells to respond to electrical impulses
Excitability
Supplies blood to the right side of the heart and inferior left ventricle
Right Coronary Artery
Constriction of arteries due to cold or stress often in the fingers cause this phenomenon
Raynaud phenomenon
Percentage of red blood cells that make up total blood volume is known as
Hematocrit
