three main functions of the lymphatic system
- drains tissue spaces of interstitial fluids that escapes from capillaries and loose connective tissue, filters, then returns it to the blood stream.
- absorbs fats and transports them to the blood stream
- plays a major role in the body’s immune system
how much of the body’s lymph nodes are in the neck?
1/3
lymph nodes are mostly made of ___
water
with some plasma
what does afferent mean?
efferent?
to bring to
away from
lymphatic flow
tissue fluid leaves the cellular interstitial spaces and becomes lymph; as it enters a lymphatic capillary, it merges with other capillaries to form an afferent lymphatic vessel; which enters a lymph node where lymph is filtered. Then it leaves the node via an efferent lymphatic vessel which travels to there nodes, then merges with other vessels to form a lymphatic trunk, which merges with other trunks and joins a collecting duct either the right lymphatic or the thoracic, which empties into a subclavian vein where the lymph is returned to the blood stream.
