Acute Inflammation - Answer -swelling-edema in response to injury
Adaptive Immune Response - Answer -recognizes and remember certain pathogens
All-or-None Law - Answer -if a nerve impulse is initiated to form an AP, it travels the length of its
axon and releases a chemical to target site
Antibo...
Arteriovenous Difference - Answer -- the amount of O2 that is extracted at tissue level
- this increases during exercise due to increased O2 uptake in muscles
Autoregulation - Answer -- self regulated by metabolic need
- due to increase in nitric oxide and PGI2
Average Aortic Blood Pressure - Answer -pressure heart pumps against ("afterload")
B-cells (Lymphocytes) - Answer -- come from marrow
- release antibodies which attach to an antigens
Basal Ganglia - Answer -slow and deliberate movement
Blood Flow Relationships - Answer -- directly proportional to pressure difference b/t two areas of
the system
, - inversely proportional to resistance
blood flow = change in pressure/resistance
Cardiovascular Changes During Prolonged Exercise - Answer -- Q is maintained
- gradual decrease in SV due to fluid loss and decreased plasma volume out of circulation
- gradual increase in HR (cardiovascular drift)
Cardiovascular Control During Exercise - Answer -- central command is primary dive
- fine-tuned at muscle via chemoreceptors, mechanoreceptors
- baroreceptors
Cardiovascular factors during exercise - Answer -- increased +linear MAP and SBP
- increased (SV) +linear 40%-50% VO2max then levels off in UT
- increased Q +linear up to 40%-50% VO2max then less steep +linear to max
- increased HR +linear up to VO2max
- increased A-VO2diff +linear up to ~50% VO2max then less steep +linear to max
Central Command Theory - Answer -- the initial signal to "drive" the cardiovascular system at the
beginning of exercise comes from higher brain centers
- fine-tuned by feedback from muscle chemoreceptors and muscle mechanoreceptors
Cerebral Cortex - Answer -- organization of complex movements
- storage of learned experiences
Chronic Inflammation - Answer -persistent infection or prolonged immune response
Circulatory Responses to Exercise - Answer -Depends on:
- type, intensity, and duration of exercise
- environmental conditions
Circulatory System Purpose - Answer -- transport O2, nutrients, and signaling molecules to tissue
- transport CO2 to lungs and wastes
- regulation of body temperature
Co-Activation - Answer -gamma and alpha working together to contract the muscle
Contractility - Answer -- strength of ventricular contraction
