Flashcards in Quiz 2 - Types of Epithelial tissues Deck (20):
1

simple squamous

very delicate, reduces friction, absorbs and secretes materials (locations: line body cavities, heart, blood vessels, alveoli of lungs)

2

Stratified squamous

in areas of severe mechanical stress (exposed body surfaces)

3

keratinized

surface of skin

4

non-keratinized

lines mouth, esophagus, anus, vagina

5

simple cuboidal

performs secretions and absorptions (locations: thyroid gland, ducts, kidney tubules)

6

simple columnar

secretion, absorption, protection (locations: lining of stomach, intestines, uterine tubes)

7

pseudostratified columnar

nucleus situated at different levels (locations: nasal cavity, trace, bronchi)

8

transitional

can stretch extensively, consists of many layers of irregularly shaped cells (locations: urinary bladder, ureter)

9

glandular epithelium

produce and secrete materials/fluids

10

types of secretions from glandular epithelium

endocrine glands and exocrine glands

11

endocrine glands

secretions enter into the blood or lymph

12

exocrine glands

secretions travel through ducts to the epithelial surface

13

types of exocrine glands

serous, mucous, mixed

14

serous

secrete watery fluid rich in enzymes

15

mucous

secretes glycoporteins (mucins) that absorb water to produce mucus

16

mixed

contains both serous and mucous secretions

17

modes of secretion

merocrine, apocrine, holocrine

18

merocrine

secretions released through exocytosis

19

aprocrine

secretions released via the loss of cytoplasm

20

holocrine

secretions released upon bursting of glandular cells
