Heart Flashcards
What is the Blood Flow process?
- Right Atrium
- Tricuspid Valve
- Right ventricle
- Pulmonary Semilunar Valve
- Pulmonary trunk
- Pulmonary arteries
- Lungs
- Pulmonary veins
- Left Atrium
- Bicuspid valve
- Left Ventricle
- Aortic semilunar valve
- Aorta
- Body
Difference of Pulmonary to systemic circulation
pulmonary (right side)= blood moves between heart and lungs
=Right >lungs>left heart
systemic (left) = blood moved between heart to rest of the body
=left>body>right heart
Define papillary muscles
cone-shaped muscular pillars of ventricle
Define Chordae tendineae
strong connective tissue strings where papillary muscles are attached
What are the visceral and parietal layers
HEART
VISCERAL - SEROUS
PERICARDIAL- SEROUS
PARIETAL
Define angioplasty
Procedure to open blocked blood vessels due to buildup of plaque
(using stent)
Define arteries, veins, capillaries
Arteries- blood goes away from heart
Veins- Blood goes back to the blood
Capillaries- Bridge between the arteries and veins
Explain the process of how heart is stimulated - 5
- Heart at rest
- action potentials spread in atrial wall
- atrial wall contracts (blood go to ventricle)
- Action potential spread to ventricle wall
- ventricle wall contracts
Explain process of cardiac muscle action potentials - 3
- depolarization phase
- plateau
- repolarization
Explain heart sounds - 2
- lubb (close of atrioventricular valve)
- dupp (close of semilunar valve)
Electrocardiogram waves?
P WAVE - depolarization of atria
QRS COMPLEX- depolarization of ventricle (q,r,s, waves)
T WAVE- repolarization of ventricle
Explain process of action potential path through heart - 5
- Sinoatrial node
- Atrioventricular node
- Atrioventricular bundle
- Right and left bundle branches
- Purkinje fibers
SA- pacemaker
AV N- connect atrium to ventricles
Purkinje- deliver action potential to cardiac muscle of all ventricles
