Exam 1
(Cardiovascular
Physiology) with
correct answers
2025/2026
Autoregulatory Control - correct answers- Most capillary beds
- Modulation of local blood flow
- Local-pressure induced (site specific for short durations)
Avian Heart Valves - correct answers- Left AV Valve: tricuspid (bicuspid in mammals), more
flappy (poorly defined cusps)
- Right AV Valve: single flap (tricuspid in mammals)
- Pulmonary Valve; tricuspid, to lungs
- Aortic Valve: tricuspid, to body
Blood Flow - correct answers- Three components to pulmonary & systemic circulation: arteries,
capillaries, veins
- Flow velocity decreases with each bifurcation (from large to small)
Blood Flow in Capillary Beds - correct answers- Gas exchange: gases move by simple diffusion,
adaptations for flight in pectoralis muscle (higher capillary density & less flow resistance)
