Lymphatic

Question 1

Answer 1

UPPER right side of the body including the brain a 1/4 of the body

Question 2

what does the thoracic duct drain

Answer 2

3/4 of the body including the left and lower right side

Question 3

where are lymphatic capillaries found

Answer 3

interlaced with arterioles and venules. collagen fibers anchor the lymphatic capillary in the tissue, interstitial fluid slips through spaces between the overlapping endothelial cells that make the lymphatic capillary

Function of lymphatic system

Answer 16

Dietary fat absorption/transport
defends the body with WBC, T+B cells

How does fat enter the lymph system

Answer 17

via lacteals/lymphatic capillary

Question 18

Fat flow in lymph sys

Answer 18

fat enter through lacteal->cisterna chyli-> thoracic duct

Question 19

Lymph characteristics

Answer 19

yellowish liquid. Like plasma but with less protein

Question 20

Lymphatic vessel characteristics

Answer 20

like blood vessels but thinner and a lower pressure but with 1 way valves

Question 21

Answer 21

squamous endothelium w/o basement membrane

lymph w/ lipids in it

Question 23

MALT

Answer 23

Mucosa associated lymphatic tissue

Question 24

BALT

Answer 24

Bronchus associated lymphatic tissue

Question 25

characteristics of tonsils

Answer 25

unencapsulated lymphoid tissue/lymph nodules

Question 26

What/ where are the tonsils

Answer 26

Lingula-base of the tongue
Pharyngeal/adenoid x2: post of nasopharynx
palantine x2: post o oropharynx

Question 27

Lymph nodes characteristics

Answer 27

1. capsule: dense IR collagenous CT
2. outer cortex: has lymphatic nodules/germinal centers-spherical clusters of cells (primarily B lymphocytes)
3. Deep to lymph nodules is an area that houses primarily T lymphocytes
4. Medulla: innermost region: houses macrophages

Question 28

Peyer’s patch characteristics

Answer 28

found in epithelial lining of small intestine/ileum: resemble lymph nodes but lymph nodules are less defined and have incomplete capsules

Question 29

Lymph capillaries characteristics

Answer 29

Blind ended, highly permeable walls allow large substances and volume of fluid to enter and exit. has many 1 way valves, lower pressure than blood vessels

Question 30

Spleen characteristics

Answer 30

made of 2 types of tissue
1. Red pulp: destroys old worn out cells
2. white pulp: contains phagocytes and lymphocytes
