Explanation:
Detailed explanation-1: -Similar to other organs, the heart relies on cardiac lymphatics to drain tissue fluid in order to maintain the steady-state interstitial fluid equilibrium. Myocardial contractions help to propel cardiac lymphatic flow.
Detailed explanation-2: -The lymphatic system utilizes both extrinsic pumps, which rely on the cyclical compression and expansion of lymphatics by surrounding tissue forces, and intrinsic pumps, which rely on the intrinsic rapid/phasic contractions of lymphatic muscle.
