WHAT ARE LYMPHATIC CAPILLARES?

Answer 9

SMALLEST OF LYMPHATIC VESSELS

CLOSED AT ONE END AND FILTER FLUID FROM BODYS CELLS AND TISSUES

Question 10

HOW ARE THE LYMPHATIC CAPILLARES CONSTRUCTED?

Answer 10

MADE OF ENDOTHELIAL CELLS CLOSELY OVERLAPPED

Question 11

WHAT DO THE ENDOTHELIAL CELLS DO?

Answer 11

ALLOW BACTERIA AND OTHER CELLS ENTRANCE INTO LYMPHATIC CAPILLARIES
LAYERED CELLS CREATES VALVE LIKE FLAPS THAT OPEN WHEN INTERSTITIAL FLUID PRESSURE IS HIGH, AND CLOSE WHEN IT IS LOW

Question 12

WHAT IS THE ROUTE OF THE LYMPHATIC SYSTEM?

Answer 12

LYMPHATIC CAPILLARIES CONVERGE TO FORM COLLECTING VESSELS
COLLECTING VESSELS
LYMPHATIC TRUNKS
COLLECTING DUCTS

Question 13

WHAT ARE THE COLLECTING VESSELS?

Answer 13

VESSELS THAT START DRAINING FLUID THROUGH LYMOH NODES

Question 14

WHAT DO THE COLLECTING VESSELS DO?

Answer 14

DRAIN FLUID FROM THE LYMPH NODES AND CONVERGE TO FORM THE LYMPHATIC TRUNKS

Question 15

WHAT DO THE LYMPHATIC TRUNKS DO?

Answer 15

6 OF THEM DRAIN LARGE AREAS OF THE BODY AND CONVERGE TO FORM THE R AND L COLLECTING DUCTS

Question 16

WHAT DOES THE R COLLECTING DUCT DO?

Answer 16

RECEIVES LYMPH FROM R ARM, R SIDE OF HEAD AND THORAX, THEN EMPTIES INTO R SUBCLAVIAN VEIN

Question 17

WHAT DOES THE L COLLECTING DUCT DO?

Answer 17

RECEIVES LYMPH FROM BELOW DIAPHRAM, L ARM, L SIDE OF HEAD, NECK AND THORAX, THEN EMPTIES INTO L SUBCLAVIAN VEIN

Question 18

WHICH COLLECTING DUCT IS THE LARGEST?

Answer 18

THE L COLLECTING DUCT BEING LARGER AND LONGER \

BEGINS AS A PROMINENT SAC IN ABDOMEN CALLED CISTERNA CHYLI

Question 19

WHY IS THE L COLLECTING DUCT LARGER?

Answer 19

BECAUSE IT DRAINS A LARGER AREA

Question 20

WHAT ARE THE MECHANISIMS OF LYMPHATIC RETURN?

Answer 20

RHYTHMIC CONTRACTING OF LYMPH VESSELS 
SKELETAL MUSCLE PUMP
THORASIC PUMP
VALVES 
BLOOD FLOWING IN SUBCLAVIAN VEINS
EXERCISE

Question 21

WHAT DOES RHYTHMIC CONTRACTING OF LYMPH VESSELS DO DURING LYMPHATIC RETURN?

Answer 21

STRETCHING OF VESSELS STIMULATES CONTRACTION

Question 22

WHAT DOES THE SKELETAL MUSCLE PUMP DO DURING LYMPHATIC RETURN?

Answer 22

WHEN MUSCLE CONTRACTS, THE LYMPHATIC VESSEL CONTRACTS FORCING LYMPH UPWARDS

Question 23

WHAT DOES THE THORASIC PUMP DO DURING LYMPHATIC RETURN?

Answer 23

INHALATION CRATES PRESSURE ON THE LYMPHATIC VESSELS

Question 24

WHAT DO THE VALVES DO DURING LYMPHATIC RETURN?

Answer 24

STOP THE BACKFLOW FOR LYMOG FROM GOING BACK DOWN THE LYMPHATIC VESSEL AFTER MUSCLE CONTRACTION

Question 25

WHAT DOES BLOOD FLOWING IN SUBCLAVIAN VEINS DO DURING LYMPHATIC RETURN?

Answer 25

FLOWING BLOOD DRAWS IN THE LYMPH

Question 26

WHAT ARE THE MAJOR TYPES OF LYMPHATIC CELLS?

Answer 26

T LYMPHOCYTES - T CELLS B LYMPHOCYTES - B CELLS NATURAL KILLER CELLS - NK CELLS

Question 27

WHAT DO T LYMPHOCYTES - T CELLS DO?

Answer 27

RECOGISE AND ATTACK FOREIGN ANTIGENS | MATURE IN THYMUS

Question 28

WHAT DO B LYMPHOCYTES - B CELLS DO?

Answer 28

ACTIVATION CAUSES PROLIFERATION AND DIFFERENTIATION INTO PLASMA CELLS THAT PRODUCE ANTIBODIES MATURE IN BONE MEMORY B CELLS THAT DO NOT DIFFERENTIATE

Question 29

WHAT DO NATURAL KILLER CELLS - NK CELLS DO?

Answer 29

ATTACKS BACTERIA, TRANSPLANTED TISSUES AND INFECTED HOST CELLS
