← Human Body & HealthWhich increased risk occurs when tendon capillaries narrow?
A)Reduced collagen fibril strength✓
B)Increased glucose energy production
C)Enhanced neuronal action potentials
D)Decreased red blood cell count
💡 Explanation
Reduced capillary diameter decreases oxygen supply; therefore, it compromises collagen production needed for tendon strength, due to disrupted cellular respiration rather than increased neuronal activity or direct blood cell effects, because the diminished blood flow impairs structural protein synthesis.
