← Human Body & HealthWhat distinguishes lymphatic drainage in tissues surrounding tumors compared to healthy tissues, under similar interstitial pressure?
A)Reduced drainage due to osmotic pressure
B)Enhanced drainage due to lymphatic contraction
C)Impaired drainage due to vessel compression✓
D)Equivalent drainage due to pressure balance
💡 Explanation
Lymphatic drainage is impaired in tumor microenvironments because solid stress and increased interstitial pressure compress lymphatic vessels. This mechanical compression reduces the efficiency of lymphatic drainage, therefore impaired drainage occurs, rather than enhanced drainage seen in healthy tissue due to pressure gradients.
