Tissues Flashcards
(42 cards)
Simple cuboidal (epithelial)
Located in kidneys.
Secretion and absorption of substance
Simple columnar (epithelial)
Located in digestive tract.
Secretion of digestive juices - microvilli to increase surface area for absorption
Stratified squamous (epithelial)
A lot of cells
Located on skin
Protective barrier
Pseudostratified columnar (epithelial)
Single cell
Secretion of mucus
Located in trachea
Areolar/ loose tissue (connective)
Located under all epithelial tissue
Wraps and cushions organs, holds and conveys tissue fluid, important with inflammation
Adipose (connective)
Located under skin and organs
Reserves food fuel, insulates, supports and protect organs
Reticular (connective)
Located spleen
Framework of soft tissue (forms support)
Dense regular (connective)
(Same direction collagen fibers)
Located ligaments/tendons
Resists pulling forces in joints
Dense irregular (connective)
(Collagen fibers different directions)
Located dermis of skin
Resists pulling force in skin
Hyaline cartilage
Located in trachea
Supports and reinforces airway, cushioning properties
(Consists chondrocyte and lacuna)
Simple squamous (epithelial)
Diffusion occurs (between o2 and co2) Located in air sacs
Ground substance
Space where nutrients and dissolved substance diffuse between blood cap and connective tissue
Fibers (3)
Collagen, elastic and reticular
Collagen fiber
Strongest. Protein collagen. White fibers. In tendons and ligaments.
Elastic fibers
Stretch and recoil. Elastin protein. Yellow fibers. Around dermis, lungs and blood vessels
Reticular fiber
Inelastic. Collagen protein reticulin. Provides support and internal framework of glands. Lines capillaries.
Fiberblast cell
Forms collagenous and elastic fibers
Mast cell
Contains/release histamine (inflammation) and heparin (anticlot)
Chondrocyte
Cells located in cartilage. Maintains cartilage matrix and reduces friction in bones.
Lacuna
Small space containing a chondrocyte or osteocyte
Integumentary
Protects body. Maintains body temp. Excrete materials. Carry out metabolic reactions. Sense stimuli. Holds blood volume.
Epidermis
Stratified squamous tissue. A vascular ( no blood supply)
Keratinocytes (epidermis cell)
Most abundant cell. Produce keratin. Protects skin and produces antibodies
Melanocytes (epidermis cell)
Produce melanin (dark pigment). Protects keratinocytes from uv rays that may cause cancer.
