Cell Types + Functions Flashcards
1
Q
simple squamous epithelium
A
- Passage of materials by passive diffusion and filtration
- Secretes lubricating substances/molecules to make up the serosae membrane
2
Q
Simple cuboidal epithelium
A
Needed to secrete and absorb
3
Q
Simple columnar epithelium
A
- Absorption + secretion of mucus, enzymes, and other substances
- Ciliated simple columnar: propels mucus or reproductive cells by cilia to get it out of body
4
Q
Pseudostratified columnar epithelium
A
secrete mucus that’s propelled by cilia
5
Q
Stratified squamous epithelium
A
- Functions to protect areas against abrasion
- Keratinized type (More keratin cell has = stronger/more protected cell is)
- Nonkeratinized type
6
Q
Stratified cuboidal epithelium
A
Protection
7
Q
Stratified columnar epithelium
A
Protect and secrete
8
Q
Transitional epithelium
A
Permits distention of urinary organs when filled with urine
9
Q
3 types of loose connective tissue
A
- areolar
- adipose
- reticular
10
Q
3 types of dense CT
A
- dense regular CT
- dense irregular CT
- elastic CT
11
Q
Areolar tissue
A
- Cells include fibroblasts, mast cells, leukocytes
- Wraps and cushions organs
- Holds and conveys tissue fluid
- Important for inflammation
12
Q
Adipose tissue
A
- Provides reserve food fuel
- Insulates against heat loss
- Supports and protects organs
13
Q
Reticular tissue
A
- Forms soft, internal skeleton (stroma)
- Supports other cell types
14
Q
Dense irregular connective tissue
A
- Withstands tension from any direction
- Provides structural support
15
Q
Dense regular connective tissue
A
- Attaches muscle to bone
- Attaches bone to bone
- Withstands great stress in one direction only
