Q-1 Flashcards
Squamous Epithelium
Location- Air sacs of lungs, lining blood vessels / flat
Function- Allow passage of lquids and gases
Epithelial tissue- 3 types
Columnar Epithelium
Location- Digestive tract lining/ long and slender
Function- Secretion, Absorbtion, Protection
Epithelial tissue- 3 types
Cuboidal Epithelium
Location- Gland ducts/ square
Function- Secretion
Epithelial tissue- 3 types
Areolar (Loose Connective)
Within muscle tissue, skin, and blood vessels/fibroblast cells (synthesize fibers and matrix) in a semifluid matrix, delicate, very flexible.
Function- Support
(Connective tissue-6 types)
Dense Connective
Tendons and ligaments/fibers, stress resistant, regularly or irregularly arranged
Function- Support
(Connective tissue-6 types)
Adipose
Aggregations throughout the body/ thin cytoplasm around fat-storage vacuole(s)
Function- Food storage, heat production organ protection
(Connective tissue-6 types)
Blood
Within heart and blood vessels/cells in a fluid matrix
Function- CO2 and O2 transport, immune functions, clotting
Connective tissue-6 types
Cartilage
ends of bone, respiratory track, nose, ear/abundant fibers, chondrocytes (secrete matrix) in lacunae (matrix cavities)
Function- Stress absorption, support, bone growth
(Connective tissue-6 types)
Bone
Skeletal structure/ cells in lacunae arranged in concentric circles surrounding haversian canals (vessel portals). Lacunae are interconnected by canaliculi (perforations in matrix)
Function- Support, protection, calcium reserve
Marrow produces blood cells
(Connective tissue-6 types)
4 components of blood
Erythrocytes, Leukocytes, Platelets, and Plasma
Skeletal
attached to skeleton/cylindrical. multinucleate, striated
Function- Voluntary movement
Muscle Tissue- 3 Types
Cardiac
heart/cylindrical, one or two nuclei, striated, intercalated disks (junctional complexes)
Function- Pump blood through body
(Muscle Tissue- 3 Types)
Smooth
Digestive track and blood vessels/ elongated, one nucleus, non-striated
Function- Involuntary movement of blood and food
(Muscle Tissue- 3 Types)
Neurons
brain, spine, network throughout body/cell body, myelinated axon, branched dendrites
Function- Conduct impulses
(Nervous Tissue- 2 types)
Glial
Surrounding neurons/ gel-like cell body with processes (projections of the cell body)
Function- Support and nourish neurons, provide myelin
(Nervous Tissue- 2 types)
Granulocytes
One of the two types of white blood cells. Neutrophils, eosinophils, and basophils
Agranulocytes
B and t lymphocytes responsible for the immune response cell nucleus rounded. No granules, monocytes engulf foreign substances including bacteria at site of infection.
Four types of animal tissue discussed in lab
Connective
Epithelial
Nervous
Muscle
