Body Organization Flashcards
Epithelial tissue properties (3)
covers body surfaces
lines body cavities
forms glands
Types of tissue (4)
- Epithelial
- connective
- muscle
- nervous
Connective tissue properties (3)
Binds and supports other tissues
Transportation (blood)
Energy storage (adipose)
Epithelial cell types (3)
squamous
cuboidal
columnar
All can be:
simple (singular layer)
Secretes/absorbs
or
stratified (2+ layers)
Protects underlying areas
Squamous epithelial cells (structure, function, example)
Flat, scale-like
For easy diffusion of O2 & CO2
Ex. Blood vessels, lungs
Cuboidal epithelial cells (structure, function, example)
Cube shaped
For secretion and absorption
Ex. Glands, kidneys
Columnar epithelial cells (structure, function, example)
Column shaped
For secretion and absorption (increased surface area)
Ex. Small intestine
Types of protein fibers in connective tissue matrix (3)
Collagen
Strong, rope like, can withstand pulling
Elastic
Contain coils which allow stretching
Ex. Skin, lungs, blood vessels
Reticular
Extensively branching collagen networks supporting soft tissue
Connective tissue types
Connective tissue proper
Specialized connective tissue
Connective tissue proper types (3)
Loose, areolar
Packing material between other tissues
Anchors skin to tissues and organs
Ex. Between muscles, around glands
Loose, adipose
Specialized for fat storage
Insulation around organs
Ex. Around kidneys, heart
Dense
Strong bands of tightly woven fibers
Ex. Tendons, ligaments, dermis
Specialized connective tissue types (3)
Cartilage
Flexible support
Cushioning
Bone Metabolizing tissue with good blood supply Protection/support Movement w/ muscle Storage Production of blood cells
Blood
Transport of O2 & CO2, nutrients, hormones, waste
Fights infections
Muscle tissue types (3)
Skeletal
Attached to bone
Long, cylindrical, Striated
Voluntarily contract
Cardiac
Wall of heart
Branching, striated, with specialized junctions
Involuntarily contract
Smooth Digestive system, blood vessels, urinary Tapered cells in sheets, no striation Propels substances Involuntarily contracts
Nervous tissue types (2)
Neurons
Generate and conduct nerve impulses
Neuroglia
Support, insulate, protect neurons
Cavities of the body (6)
Ventral -Thoracic --pleural (lung) --pericardial (heart) -abdominal Dorsal -cranial -spinal
Organ systems (11)
Integumentary Skeletal Muscular Nervous Endocrine Cardiovascular Lymphatic Respiratory Digestive Urinary Reproductive
