100% Verified Answers
Q1: lymphatic system
A: Composed of a network of vessels, ducts, nodes, and organs. Provides defense against
infection.
Q2: Spleen
A: o Blood organ
o Cleans our blood just like lymphatic vessels
o Curves around left side of stomach
Q3: Thymus
A: o In thorax
o Most active during youth
o Sits in front of the trachea
o Matures T-Cells
Q4: Tonsils
A: o Pharyngeal region
o Ring around back of our throat
Q5: Peyer's patches
A: patches of lymphatic tissue
Q6: Lymph capillaries
A: microscopic
extend into spaces of the tissue
consists of single layer cells
allows for interstitial fluid to enter the lymph capillaries
Q7: Lymph vessels
A: As the lymphatic capillaries merge they form lymphatic vessels
Q8: Lymphatic ducts
A: • Lymphatic trunks drain lymph from larger portions of the body
• They join up with one of the collecting ducts
o THORACIC DUCT
o RIGHT LYMPHATIC DUCT
Q9: thoracic duct
, A: larger and longer
receives lymph from lower body,left arm and empty in subclavian vein
Q10: right lymphatic duct
A: receives blood from the right side of the; head, neck, right arm, right thorax
Q11: Discuss the mechanisms responsible for lymph flow
A: • Lymph movement controlled by muscular movement
o Lymph fluid under low pressure
o Requires assistance in returning to the heart
o Skeletal muscular contraction and respiration assist moving lymph
o Multiple valves
Q12: The interior of the node
A: • Contains compartments and channels
• Through which lymph circulates
Q13: nodes
A: • Grouped along lymphatic pathways
• Not found within CNS
• Centers for lymphocytes production
!!!LYMPHOCYTES FUNCTION TO FIGHT FOREIGN PARTICLES AS THEY PASS THROUGH
THE NODE!!!
Q14: Thymosin
A: stimulates the maturation of lymphocytes into T cells of the immune system
secreted by thymus gland
Q15: spleen
A: largest lymphatic organs
luq
destroys old rbc
"rbc graveyard"
Q16: immunity
A: Resistance to disease
Q17: Why is immunity essential to life?
A: • Built in - specific defense system against disease
• Silent portable army
• Protect us from potentially fatal disease processes
, Q18: identify the components of the immune system
A: • Lymphatics
• Skin and mucous membranes
• Interferons
• Enzymes
• Leukocytes
Q19: two phagocytic cells
A: neutrophils and monocytes
Q20: neutrophils
A: Increase during infections
phagocytosis of small pathogenic micro - organisms
Q21: monocytes
A: Give rise to macrophages
An aggressive phagocyte
Capable of digesting
o Bacteria
o Cellular debris
o Cancerous cells
Q22: non-specific defense mechanisms
A: respond immediately against defence
skin, mucosal surfaces, tears, saliva, gastric juices
Q23: specific defence mechanism
A: Built in
Stalks and eliminates pathogens
Recognizes something as foreign -inactivates and removes it
Responsible for our immunity
Q24: Humoral
A: antibody-mediated immunity
Q25: Cellular immunity
A: lymphocytes
Q26: function and sources of histamine
A: • Source: basophils / mast cells
• Inflammatory chemical
