How Would Muscle Contraction Affect Lymphokinetic Action

Multiple Choice

How would muscle contraction affect lymphokinetic action?

A) There is no association between muscle contraction and lymphokinetic action.
B) A decreased flow of lymph that occurs with increased physical activity helps return fluid to the cardiovascular system.
C) Contraction of the smooth muscle in the thoracic vessel walls prohibit lymphatic vessels from pulsing rhythmically and, thus, helps to keep lymph from moving from one valved segment to the next.
D) Increased external pressure from muscle contraction also increases lymphatic pressure, which results in keeping lymph moving in only one direction.
