Function of specialised animal tissues (C2) Flashcards
1
Q
simple squamous epithelium
A
- as a barrier,regulating movement of substances across it
- permits diffusuion of gases across alveolus
- protects underlying tissues
2
Q
simple cuboidal epithelium
A
- secretion, absorption and protection
3
Q
simple cilliated columnar epithelium
A
- mechanical support and protection
4
Q
pseudostratified epithelium
A
- goblet cells secrete mucus as lubricant and trap dust particlles and microbes
- cillia in cilliated epithelium move fluids to the pharynx for swallowing
5
Q
stratified squamous epithelium
A
-protective layer in areas of higher friction
6
Q
compound stratified cubodial epithelium
A
-transport
7
Q
stratified columnar epithelium
A
-transport
8
Q
transitional epithelium
A
- allow stretching of blasdder
- barrier against urine flowing out into the surrounding tissues
9
Q
endocrine gland
A
- hormones are secreted by the endocrine glands into the surrounding capillaries and the bloodstream carry them to the target cells or organ.
10
Q
exocrine gland
A
-transport secretion the the surface
11
Q
hyaline cartilage
A
- located in the cartilage of trachea and bronchi to keep them open.
- covers the ends of the bones to reduce friction between joints during movement
- form embryonic skeleton in many bony vertebrates. (cartilage is replaced by bony tissue)
- form the skeleton of cartilaginous fish
12
Q
bone
A
- give body shape and provide framework for support
- protect internal organs
- provides surfaces for attachment of skeletal muscles to enable movement
- act as a reservoir for calcium and phosphorus
- site for blood cell production in the bone marrow
13
Q
erythrocytes
A
-transport oxygen used in aerobic respiration and some carbon dioxide
14
Q
neutrophils
A
-engulf microorganisms
15
Q
eosinophils
A
- help to control allergic responses
- release hydrolytic enzymes to digest parasitic worms
