unit 3 - tissues Flashcards
• single layer, thin, flat ended cells
• function: diffusion and filtration
• location: found in air sacs of the lungs, walls of capillaries
simple squamous (epithelial)
• function: secretion and absorption
• location: lining of kidney tubules, ducts/glands, covering surface of ovaries
simple cuboidal (epithelial)
• single layer, elongated cells, nucleus near basement membrane
• function: secretion and absorption
• location: lining of digestive tract and uterus
• goblet cells; mucus
simple columnar (epithelial)
• multi layer
• functions: protection
• location: body cavities such as skin, mouth, anus, and vagina
stratified squamous (epithelial)
• “stratified” but scattered nuclei gives the illusion of layers
• function: secretion and cilia-aided movement
• location: lining air passages and tubes of the reproductive track
pseudo-stratified squamous
• thick, layered, cube cells
• function: contract and stretch to form a barrier to block diffusion
• location: lining of urinary bladder and uterus
transitional (epithelial)
• bonds skin to organs, organs to organs, space between muscles
• throughout body
loose connective tissue
• function: protect, insulation to preserve heat
• location: beneath skin, around kidneys, around eyeballs, abdominal membrane
adipose tissue (fat)
• rigid due to salt mineralize
• layers: lamellae, haversian canal, osteocytes
bone tissue (ossesous tissue)
• destruction of large quantities of tonic and other particles
reticuloendothelial - immune phagocytes
•voluntary
•attached to bone
skeletal muscle
• involuntary
• location: gastrointestinal tract, stomach, urinary tract, and uterus
smooth muscle
• involuntary
• located gastrointestinal tract, stomach, urinary tract, and uterus
smooth muscle
• wall of heart
• allows electrochemical impulses to be conveyed (heart beat)
cardiac muscle
• transmit signals
• electrochemical signals
neurons
