Which of the following is NOT a method that maintains lymph flow?

Biology
1 answer:
brilliants [131]4 years ago
3 0

The correct answer is: D. breathing

Lymphatic system is an open system that does not have a central pump (such as heart in the circulatory system), so the flow of the lymph is different than blood flow. Transport and movement of the lymph are slow and sporadic. Lymph flow occurs thanks to:  

• peristalsis – contraction and relaxation smooth muscle tissue,  

• valves- so that lymph doesn’t flow backwards along the vessels

• contraction of adjacent skeletal muscle .
