100
How adenosine builds up in muscle tissue
What is use and breakdown of ATP in muscle contraction, myosin head activation
100
Type of cells lining capillaries

100
If blood flow increases, this occurs in order to maintain blood pressure
What is vasodilation
200
Pressure causing fluids back into capillary; Pi
What is interstitial hydrostatic pressure
200
In the Starling equation, a negative Jv value represents this.
Jv=Kf[(Pc-Pi) - (Pic-Pii)]
What is reabsorption
200
Four general causes of edema
What is increased Pc (capillary hydrostatic pressure), decreased pi-c (capillary oncotic pressure), increased Kf (hydraulic conductance), and impaired lymphatic drainage
200
If blood flow decreases, this occurs in order to maintain blood pressure
What is vasoconstriction
200
Norepinephrine binding to alpha-1 receptor results in these steps to cause vasoconstriction
What is increase in IP3, increase in Ca2+, increase in Ca2+-Calmodulin complex, increase in MLCK activation, smooth muscle contraction
300
Pressure from proteins pulling fluids into blood vessel; pi-c
What is capillary oncotic pressure
300
In the Starling equation, a positive Jv value denotes this.
Jv=Kf[(Pc-Pi) - (Pic-Pii)]
What is filtration
300
These three metabolites lead to vasodilation of smooth muscle, consequently increased blood flow to skeletal muscle
What are lactate, K+, and adenosine
300
Decrease in [PO2] and increase in [CO2] leads to this in smooth muscle
What is vasodilation
300
Epinephrine binding to beta-2 receptors results in these series of steps to cause vasodilation.
What is increase in cAMP, increase PKA activation, inhibition of MLCK, decrease in Ca2+, smooth muscle relaxation.
400
Pressure pushing fluids out, filtering into tissue; pi-i
What is interstitial oncotic pressure
400
The term (and constant) for capillary permeability
What is hydraulic conductance, Kf
400
Stimulation of this receptor on smooth muscles leads to vasoconstriction
What is alpha-1
400
Stimulation of this receptor on smooth muscles leads to vasodilation
What is beta-2
400
During a workout, high levels of (1) ion induce vasodilation due to (2)
What is K+, muscle cell lysis
500
The two pressures mostly responsible for movement of fluid across capillary wall
What is Pc (capillary hydrostatic pressure) & pi-c (capillary oncotic pressure)
500
7200L of blood pumped & filtered per day, with 7195L reabsorbed into the venous system. Where the remaining 5L go
What is the Lymphatic system
500
Definition of hyperemia
What is increased blood flow
500
Term for vessel's ability to react and respond to change in blood flow or pressure through dilation or constriction
What is autoregulation of blood flow
500
This disease is a result of vasoconstriction at extremities, leading to lack of cutaneous blood flow and "white" fingers
