- AIncreased oxygen transport to tissues.
- BAccumulation of tissue fluid (edema) and impaired immune response.
- CEnhanced digestion and absorption of fats.
- DReduced blood pressure due to lower blood volume.
The lymphatic system is responsible for draining excess interstitial fluid (tissue fluid) back into the bloodstream and plays a crucial role in immunity. Impairment would lead to fluid accumulation (edema) and a compromised immune system.
