Flashcards in Organs Summary Deck (30):
1

Liver

Makes bile
Detoxes harmful substances
Phagocytizes bacteria and used RBCs and WBCs
Stores glucose, vitamins, iron
makes proteins and aa

2

Gallbladder

stores bile
attached to liver right lobe

3

Esophagus

Pierces diaphragm at esophageal hiatus
Meets stomach at cardiac orifice

4

Layers of GI Tract (Deep to Superficial)

Mucosa, Submucosa, Muscularis Externa, Serosa

5

Parts of Mucosa (Deep to Superficial)

Epithelium, Lamina propria, Muscularis mucosae

6

Epithelium

Protection or secretion and absorption

7

Lamina propria

provides epithelium with blood and lymph supply
contains MALT

8

MALT

nodules of lymphatic tissue
protect GI Tract from bacteria and pathogens

9

Muscularis Mucosae

smooth muscle for local expansion

10

Submucosa

contains Submucosal nerve plexus (Meissner's plexus)

11

Submucosal Nerve Plexus
Meissner's Plexus

part of ANS that innervates mucosa and submucosa

12

Muscularis Externa

SM for peristalsis
contains major nerve supply of GI

13

Stomach

stores, mixes, breaks down food
cardiac and pyloric sphincters

14

Duodenum

pyloric sphincter to duodenojejunal junction

15

Jejunum and Ileum

Duodenojejunal junction to ileocecal junction

16

Small Intestine Function

Mechanical- bile splits fat into smaller globules
Chemical- complete digestion of carbs, proteins, fats, nucleic acids
Absorption- 90%

17

Cecum

beginning of LI, below ileocecal junction

18

Appendix

lined with lymphatic nodules that serve immune functions

19

Ascending Colon

Ileocecal junction to right hepatic (colic) flexure

20

Transverse Colon

right colic (hepatic) flexure to left colic (splenic) flexure

21

Descending Colon

Splenic flexure to left iliac fossa

22

Large Intestine Function

Mechanical- contractions
Chemical- result of bacteria
Absorption- Vit K, B, electrolytes, water
Defecation

23

Pancreas

Exocrine- makes digestive enzymes
Endocrine- makes hormones that raise and lower blood glucose levels

24

Spleen

largest mass of lymphatic tissue
makes antibodies
phagocytosis of bacteria and old RBC and platelets
platelet reservoir

25

Kidneys

retroperitoneal (b/t peritoneum and abdomen wall)
makes hormones
absorbs minerals
filters blood
makes urine

26

Adrenal Glands

Sits on top of kidneys
cortex and medulla secrete hormones

27

Peritoneum

Serous membrane lining abdominal and pelvic cavity walls

28

Parietal Peritoneum

membrane lining wall of abdominopelvic cavity

29

Visceral Peritoneum

Covers surface of organs, continuous with parietal peritoneum

30

Peritoneal Cavity

space between parietal and visceral peritoneum
