Review Note

beta vs alpha effects on peripheral resistance: 

beta: {{c1::relax}} blood vessles
*isoproterenol → stimulates more beta than alpha → decreased peripheral resistance → reflex/compensatory {{c3::tachycardia}} (increase HR)
→ decreased {{c2::diastolic}} BP due to decrease resistance
→ increased {{c2::systolic}} BP due to increased HR and CO 


alpha: {{c1::constricts}} blood vessels
*norepinephrine → stimulates more alpha than beta → increased peripheral resistance → slight decrease in HR (not rlly seen clinically) 
→ {{c4::increase::increase/decrease}} in both systolic and diastolic BPs due to increased resistance


equal beta and alpha
*epinephrine → stimulates alpha and beta equally → slight decrease in resistance → {{c6::increase::increase/decrease}} in HR
→ increased {{c5::systolic}} BP
→ decreased {{c5::diastolic}} BP
