CV 7: Vasculature, Arteries & Blood Pressure
Flow
Resistance
Inverse relationship with radius
Pressure Change
Velocity
Cross-sectional area
Vasculature
Arteries
Elasticity = BP maintenance
Large radius = Less resistance = More flow
Arterial BP regulation
Arterial baroreceptors
Negative feedback mechanism to sympathetic division
Central and Peripheral chemoreceptors
Ties to the respiratory system; generally pressor effect
Angina pectoris is caused by stimulation of the peripheral
Cardiopulmonary receptors
Same as arterial but with the chamber of the heart
Reduce water volume via many chemicals
Hypothalamus
Temp = pressor
Posterolateral = pressor
Anterior = depressor
Cerebral cortex
Motor = pressor; Emotion = depressor
Skin
Pain = pressor
Distension = depressor
Endothelium
