introduction Flashcards
define physiology
study of the normal functioning of a living organism and its component parts. it also the science of the normal functions of the body and its mechanisms since it explains how body structures work and why they work.
define anatomy
branch of science which deals with the structure, position and size of organs as well as describes the minute structures of cells and organelles microscopically.
define pathology
the study of what is not normal, the patterns, causes, mechanisms and effect of diseases. It is concerned on gross and microscopic changes in structure which affects the function of the organ.
define pathophysiology
the study of physiology in diseased state. It emphasizes the alterations in the normal function because of changes in structure.
why is anatomy and physiology interlinked
because in order to understand the functions of the different organs and systems in our body, we should be able to locate and identify these organs
the categories of physiology
human
animal
cellular
plant
viral
veterinary
difference between veterinary and animal physiology
animal physio is a broader aspect of physiology. veterinary physiology focuses only on domestic animals
levels of organizations of the human body
atoms-cells-tissues0organs-organ system-organism
the smallest structure capable of carrying out all life processes.
cell
what are the 4 types of tissues
epithelia
connective
muscular
nervous
lines cavities and surfaces or form secretory parts of glands
epithelial tissue
it consists of layers of cells that form impermeable barriers
epithelial tissue
examples of epithelial tissue
skin
respiratory
GIT epithelium
made up of cells and cellular materials produced by these cells. functions as structural support of body components
connective tissue
examples of connective tissue
cartilage, bone, ligament, blood
cells which contract or produce movement of the body, beating of the heart and fluid flow in internal organs
muscular tissue
types of muscular tissue
smooth
cardiac
skeletal
cells with specialized property of conducting and transmitting information or signals around the body
nervous tissue
the functional unit of body
organs
can organs have multiple functions
yes
nutrient supply systems
digestive
cardiovascular
respiratory
waste removal system
respiratory
urinary
regulatory systems
nervous system
endocrine system
what are the 4 major constituents of the nervous system
sensory input
central nervous
autonomic system
