How many valves does the heart have
Four
What are ventricles separated by
Atrioventricular septum
What do ventricles do
Blood pumping chambers
What are the two inferior chambers
Right and left ventricles
What is the atria
Blood receiving chamber
What are the right and left atrium divided by
Inter atrial septum
Where does deoxygenated blood go
Right atrium from vena cava
What happens when right ventricle contracts
Blood deoxygenates blood to pulmonary artery
Where does deoxygenated blood go after pulmonary artery
Pulmonary semilunar valve to lungs
Where does deoxygenated blood go after lungs
Pulmonary veins
How many parts are in the cardiac cycle
4
What are the parts of the cardiac cycle
Volume change pressure change ekg heart sound
What is the conduction system
Ensures the heart chambers contract in coordination
What is the pacemaker
Sa node
Where is the SA node
Upper wall of right atrium
Where does the pulse from SA node go
Right and left atria
What does a contracted atria do
Forces blood to ventricles
Where is the AV node
Right ventricles wall
What is the contraction of ventricles called
Systole
What is the rest phase called
Diastole
How can we control the heart
Epinephrine or neophenphrine
What are lymph
Thin walled vessels
What does lymph do
One way valves to maintain flow in one direction
What do capillaries do
Absorb excess tissue fluid
