Lymphatic System and Astringents

Question 1

capillaries.

Question 2

edema.

Answer 2

fluid retention

Question 3

causes of edema

Answer 3

• protein blocking reabsorption,
• blocked lymphatic nodes
• improper kidney functioning.

Question 4

Thoracic Pump:

Answer 4

acts as a negative pressure during respiration, moving fluid along the vessels (similar to sucking on a straw).

Question 5

Muscle Pump:

Answer 5

This is the action of the muscles pushing against the vessels, forcing the flow along the vessels.

Question 6

main functions of the lymphatic system are:

Answer 6

1. Draining interstitial fluids
2. Transporting dietary fats and fat-soluble vitamins absorbed in the GI
3. Protection against invasion as part of the immune systems’ response

Question 7

where are the major groupings of lymph nodes ?

Answer 7

• neck
• armpits,
• breast area (in fact, the breasts are specialized lymphatic nodes)
• groin area

Question 8

what do lymph nodes do

Answer 8

work as cleaning or filtering stations along the lymphatic system

Question 9

Lymph

Answer 9

the fluid flowing in this system

Question 10

receptaculum chyli.

Answer 10

the lower part of the thoracic duct where chyle is collected

Question 11

Astringents

Answer 11

herbal agents which draw together soft organic tissue.

They bring about contraction, firm and dry up secretions and generally make tissues more dense.

Question 12

what do most astringents have?

Answer 12

Most astringents harbour either tannic or gallic acid.

Question 13

astringents are used to treate:

Answer 13

• cankers
• to diminish excessive mucous secretions
• to strengthen and contract a relaxed or weakened condition of muscle fiber
• to treat diarrhea and hemorrhoids

Question 14

Causes of edema

Answer 14

• protein blocking reabsorption
• blocked lymphatic nodes
• improper kidney functioning.
• triggered by female hormone
  imbalance

Question 15

what do the lymph nodes do?

Answer 15

nodes work as cleaning or filtering stations along the lymphatic system. If the lympathic system gets toxic it starts backing up.
If it backs up too much, death follows

Question 16

how does lymph flow?

Answer 16

moves from the left side of the head to the neck, chest, left arm, abdomen and lower limbs where it is collected into the thoracic duct. In turn, the duct empties into the left
innominate vein of the venous system. There is a much smaller right lymphatic duct receiving lymph from the right side of the head flowing to the neck, chest and right arm. This pours into the right innominate vein

Question 17

chyle

Answer 17

selected fats, which are called collected in the instestines

Question 18

spleen

Answer 18

• largest lymphoid organ
• found opposite the liver on the left side of the body
• lies under the diaphragm and posterior and lateral to the stomach
• stores an emergency supply of
  blood and lymphocytes as well as many macrophages.

Question 19

Thymus gland

Answer 19

• located in the anterior thorax, between the great vessels and the sternum
• where lymphocytes go to become T-cells, acquiring the capacity to respond to certain antigens

Question 20

Tonsils

Answer 20

• pharyngeal tonsils (adenoids) are embedded in the posterior wall of the nasopharynx.
• The palatine tonsils are situated in the space between the pharyngopalatine
  and glossopalatine arch.
• The lingual tonsils are located at the base of the tongue.
• These locations are strategically situated to protect against invasion of
  foreign substances that are inhaled or ingested.
• They contain large numbers of T and B lymphocytes as well
  as macrophages.
