Definition
Squamos
(flat, e.g.epidermis)
cuboidal
(square, e.g. salivary ducts)
columnar
(tall and thin, e.g. lining of digestive & resp. tracts)
|
|
|
Term
|
Definition
-have ducts
-secrete chemicals outside of body or into digestive tract
-e.g. sweat glands, majority of pancreas, etc |
|
|
Term
|
Definition
no ducts
-secrete chemicals (HORMONES) into blood
e.g. dopamine, adrenaline, epinephrine
-e.g. adrenal gland, certain cells of pancreas

Term
|
Definition
Sparse scattering of cells in an extracellular matrix;
Functions:
a.) structural support and binding of other tissues
b.) defense against foreign particles or organisms
c.) diffusion of nutrients from blood vessels to other cells

Term
|
Definition
joint surfaces; supports and protects |
|
|
Term
|
Definition
transport materials (nutrients, oxygen, wastes) around body & immunity
|
|
|
Term
|
Definition
structure, protection, aid in movement

|
Term
|
Definition
dynamic internal constancy
Organ systems help maintain homeostasis
|
|
|
Term
|
Definition
•Results in a return to
homeostatic equilibrium because the response reduces stimulus (stress)
• Examples:
– Regulation of blood
glucose
– Regulation of body
temperature
– Pretty much the
majority of physiologic
mechanisms
