Which of the following factors accounts for the fact that the passage of lymph through a lymph node is slowed down to allow time for cleansing action? There are more afferent vessels than efferent vessels There are valves where the afferent vessels enter the node to regulate the flow of lymph Lymph nodes are located where flow is naturally slow because there is no pressure gradient. b. 23.

Answer 1

some move (21) (b) interstitial fluid that has entered a lymph Capillary. *keep As the blood passes through the capillaries in tissues water along with many small water soluble substances out into the spaces between the cells of tissues leaving the larger proteins and most of the formed elements in the blood vessels. This fluid released out is called the interstitial fluid . This fluid is later collected by lymphatic system. (22) (C) Lymph nodes are located where flow is there pressure slow because naturally gradient. is no (23) (0) (29) (c) Pharyngeal Pathogen (95) @) lymphocytes Non specific immune defense is also known Innate immunity. immunity.
