- B cell growth factor
- secreted by helper T cells
- shunt blood away from a fetus' pulmonary circulation
- foramen ovale and ductus arteriosus
- fascicles
- a subset of the whole muscle in a bundle
- AV valves close
- lub
- laminar blood flow through valves
- no murmur
- semilunars close
- dup
- bicuspid
- left atrioventricular (mitral) valve
- layer of leukocytes and platelets
- buffy coat
- plasma cell
- the activated B cell that produes antibodies
- norepinephrine released from sympathetic postganglionic neurons causes
- increased contractility and heart rate
- thin filaments (actin)
- six of these are organized in a circle
- triscuspid
- right atrioventricular valve
- macrophage
- immune cell presents bacteria antigen to the B and T lymphocytes
- the dicrotic notch in the aortic pressure is due to
- sudden elastic recoil of elastic aorta after valves close
- cardiac muscle
- is striated, has intercalated discs, long duration action potential that plateaus before it repolarizes, is autorhymic and influenced by the autonomic NS, has drifting resting potential
- fibrin
- the final clotting factor that forms the entrapping meshwork
- smoth muscle
- type of muscle that is not striated
- type II white muscle fibers
- glycolytic, fatiguable, anaerobic, fast, becomes larger with high resistance training
- depolarization of the ventricles is associated with what electrical event
- QRS complex
- the frank-starling law can be applied to deduce that
- greater venous filling and greater end-diastolic volume increases stroke volume
- monocytes
- precursor leukocytes to wandering macrophages
- killer T cells
- most likely to attack cancer cells
- anemia
- inadequate amounts of erythrocytes
- thick filaments (myosin)
- crossbridges are a part of these proteins
- coronary vessels run in which layer
- epicardium/visceral pericardium
- myofibrils
- these increase in number with weight training
- interleukin I
- secreted by macrophages
- T helper cells are destroyed by a virus known as
- human immunodeficiency virus
- skeletal muscle
- type of muscle that is not involuntary
- pulmonary artery or trunk
- the output vessel of the right ventricl
- leaky valve
- swishing sound
- parasympathetic stimulation of the heart occurs by way of
- X. Vagus nerve
- muscle fibers
- these are multinucleated muscle cells
- type I red muscle fibers
- aerobic, oxidative, 1/10 the fore of the other, has more myglobin, has high capillary density
