- carry blood to heart from capillaries
- veins
- carry blood from heart to capillaries
- artery
- Which chambers carry deoxynated blood
- right atria and right ventricle
- pacemaker of the heart
- SA node
- What is the path of pulmonary circulation
- Blood enter heart from superior and inferior vena cava in RA thru tricuspid valve into RV thru pulmonary semilunar valve and pulmonary artery to lungs
- what is the path of systemic circulation
- Blood enters heart from lungs thru pulmonary veins into LA thru bicuspid into LV thru aortic semilunar valve and Aorta into the body
- Afterload
- Amount of blood in the left ventricle at the end of diastole;the pressure generated at the end of diastole
- Hemodynamics
- Study of the movement of blood and the forces that affect it
- Preload
- amount of resistance the Left ventricle must generate to open the aortic valve
- Dysrhythmia
- Disturbance of rhythm;arrhythmia
- perfusion
- passage of blood through the vessels of an organ
- Bradycardia
- slow heart rate, less than 60bpm
- palpitation
- heartbeat that is strong rapid or irregular enough that the person is aware of it
- tachycardia
- rapid heart rate greater than 100bpm
- hypertrophy
- enlargement of existing cells resulting in increased size of an organ or tissue
- regurgitation
- backward flow of blood in the heart
- conductivity
- ability of the cell to transmit electrical impulses rapidly and efficiently to distant regions of the heart
- contractility
- capacity for shortening in response to stimuli
- automaticity
- ability of a cell to generate an impulse without external stimulation
- aortic valve
- the valve that prevents blood from returning to the LV
- Tricuspid valve
- the valve that prevents blood from returning to the RA
- Mitral or bicuspid valve
- valve the prevents blood from returning to the LA
- Septum
- partition that seperates the heart chambers
- pulmonic valve
- valve the prevents blood from returning to the RV
- Leukopenia
- Low WBC count
