Function of specialised animal tissues (C2) Flashcards
simple squamous epithelium
- as a barrier,regulating movement of substances across it
- permits diffusuion of gases across alveolus
- protects underlying tissues
simple cuboidal epithelium
- secretion, absorption and protection
simple cilliated columnar epithelium
- mechanical support and protection
pseudostratified epithelium
- goblet cells secrete mucus as lubricant and trap dust particlles and microbes
- cillia in cilliated epithelium move fluids to the pharynx for swallowing
stratified squamous epithelium
-protective layer in areas of higher friction
compound stratified cubodial epithelium
-transport
stratified columnar epithelium
-transport
transitional epithelium
- allow stretching of blasdder
- barrier against urine flowing out into the surrounding tissues
endocrine gland
- hormones are secreted by the endocrine glands into the surrounding capillaries and the bloodstream carry them to the target cells or organ.
exocrine gland
-transport secretion the the surface
hyaline cartilage
- 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
bone
- 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
erythrocytes
-transport oxygen used in aerobic respiration and some carbon dioxide
neutrophils
-engulf microorganisms
eosinophils
- help to control allergic responses
- release hydrolytic enzymes to digest parasitic worms
basophils
- secrete histamine which involve inflammation and allergic reactions
- secrete heparin which prevents blood clotting in the body
lymphocytes
- B-lymphocytes-> produce antiboies that promote the destruction of the antigens or neutralise toxins
- T-lymphocytes-> attack and destroy infected cells
monocytes
- engulf antigens
- engulf and destroy dead and damaged cells of the body
blood
- transport system
- homeostasis
- protection
