Lymphatic and Immune System - Exam 3
Questions And Answers
Lymphatic System - - correct answer ✅Network of organs and
vein-like vessels
Lymphatic System Functions - - correct answer ✅1. Fluid recovery
(a) Capillaries collect most of fluid they pump out but the 15% that
isn't picked up is picked up by lymphatic system
2. Immunity
(a) inspects & picks up foreign cells & chemicals from tissues
(b) activates immune responses
3. Lipid absorption
(a) small intestine to lacteals to absorb dietary lipids
Components of the Lymphatic System - - correct answer ✅1.
Lymph = interstitial fluid that capillaries didn't pick up
2. Lymphatic vessels = transport lymph (similar to blood vessels)
(a) empty into capillaries which penetrate tissue
(b) collecting vessels to converged capillaries which travel beside
veins & arteries and empty into lymph nodes
3. Lymphatic tissue = cells found in mucous membranes that have
roles in defense and immunity
4. Lymphatic organs = defined sites w/ separation from neighboring
tissue
, Lymphatic and Immune System - Exam 3
Questions And Answers
(a) red bone marrow, thymus, lymph nodes, tonsils, & spleen
5. Lymphatic trunk
(a) goes to converged collecting vessels
(b) body has 6
6. Collecting ducts
(a) go to converged lymphatic trunks
(b) body has 2
Where does lymph come from and why do we call it lymph? - -
correct answer ✅-Comes from interstitial fluid outside of lymph
vessels
-Becomes "lymph fluid" once it enters the lymph vessels
-Plasma in the blood system gets pumped out into interstitial space
and becomes interstitial fluid and gets picked up by lymphatic
vessels and becomes lymph fluid
Elephantiasis - - correct answer ✅Lymphatic system is not
collecting fluid out of the leg
Areas of lymph node concentration - - correct answer ✅Large
intestine
-A lot of mucous membrane
