Characteristics Of Organisms Flashcards
The sum of all chemical processes
Metabolism
Breaking down complex molecules like proteins into amino acids
Catabolism
Process of Using amino acids to build new proteins
Anabolism
Process of being able to detect and respond to internal and external stimuli
Responsiveness
The development and specialization of cells
Differentiation
Increase in cell number
Hyperplasia
Increase in cell size
Hypertrophy
Groups of cells with the same origin and general function
Tissues
What is the microscopic study of tissues called?
Histology
What type of epithelium forms the secreting portion of glands?
Glandular epithelium
What glands do glandular epithelium form?
Thyroid, adrenal, sweat glands or sabaceous glands.
Glands that secrete into the blood
Endocrine
Glands that secrete to the outside of the body
Exocrine
The interior lining of blood cells
Lumen
3 characteristics of epithelial tissue
Avascular, innervated, proliferative
Define innervated
Extensive nerve endings
define Proliferative
High rate of cell division
One cell layer thick
Simple
Two or more cell layers
Stratified
Single layer of cells that appear to have more than one layer
Pseudostratified
Thin flat cells
Squamous
Describe squamous cell nuclei from the apical view and side view
Apical: appears round
Side: appear flat
Cube like cells
Cuboidal
Describe cuboidal nuclei
Round and centrally located
Tall cells
Columnar
Describe columnar nuclei
Oval
Irregularly shaped cells
Transitional
Simple squamous epithelium the forms the epithelial layer of serous membranes
Mesothelium
Where is mesothelium located?
The peritoneum (abdominopelvic)
Pericardium (heart)
Pleura (lungs)
Simple squamous epithelium the lines the cardiovascular and lymphatic systems
Endothelium
Where do you find endothelium?
Heart, blood vessels, lymphatic vessels
