Levels of organization
Organelle Level
small structures inside the cell that helps functioning
nucleolus, nucleus, ribosome, vesicle, rough endoplasmic reticulum, Golgi apparatus, smooth endoplasmic reticulum, mitochondria, vacuole, lysosome
Cellular Level
the small basic structure of any organism
animal cell, plant cell
Tissue Level
integrated group of similar cells with common structures and functions
epithelial tissue
closely packed sheets covering body surface and lining internal organs/cavities
basal lamina
apical surface
functions: protect barrier, exchange air and fluid
has different # of cell layers and different shape
squamus = thin, exchange from diffusion
cubodial and columnar: secretion or absorption
connective tissue
sparce population if cell scattered through matrix.
types
loose connective tissue
fibrous connective tissue
adipose tissue
cartilage
bone
blood
muscle tissue
muscle fibers, that contains molecules of contractile proteins
types of muscle
skeletal muscle
cardiac muscle
smooth muscle
nervous tissue
stimuli and transmit of information
found in brain and spinal cord
usually we call these tissues neurons
Organ Level
a task made from the performance of two ro more tissues
heart, liver, lungs, kidney,
Organ system level
a vital body function made by the performance of multiple organs
circulatory system, respiratory system
Organism
multiple organs functioning together as one unit
animals, human
