Physiology is
The study of how living organism function. It is concerned with complex processes that depends on the intergated fuctions of many organs in the body.
physiologists are concerned with
function and intergration
Pathophysiology is
study of diseases state
What are the 4 major categories of cell classification
Muscle cell
Neurons
epitheial cells
connectivie Tissue Cell
what are the three types of muscle cells
Skeletal cell
cardiac cell
smooth cell
The four general types of tissue
muscle tissue
nervous tissue
epithelial tissue
connective tissue
What is the definition of Tissue
differentiated cells with simular properties.
Types of Connective tissue
loose, dense, blood, adipose, cartilage, bone
What is a connective tissue cell
cells that connect anchor and support the structure of the body.
Muscles cells are specialized to ….. and the 3 types are….
Specialized to generate force the three types are cardiac, skeletal, adn smooth.
Control of the cardiac and smooth…… and skeletal muscle control is …
involuntary and voluntary
What are epithelial cells
They are specialized cell for the selective secretion and absorption of ions and organic molecules and they are for protection
What are the three types of epithelial cells
- cuboidal (cube shaped)
- columnar (elongated)
- squamous (flatted)
- ciliated
What are epithelial tissue
known as epithelium they form many different epithelium cells, they can be arraigned in single cell thick tissue callled simple epithelium or thiskcer tissue made of numerous layers called stratified epithelium.
The immediate environment surrounding each individual cell is made of
Extracellular matrix and the extracellular fluid.
ECM is made of
proteins, polysaccharides and in some case minerals
Proteins of the ECM consists of
Fibres, collagen fibres, elastin fibres and non fibrous protein like carbs
Organs are composed of
two or more of the tissue types
ECM have two general functions
it provides scaffold for cellular attachments, and it it transmits information in the form of chemical messengers to the cells to help regulate their activity, migration, growth, and differentiation.
Organ systems are
a collection of organs that together perform an overall function.
What does the term body fluid refer to
water solutions of dissolved substances like oxygen, nutrients, and wastes in the body.
What does extracellular fluid mean
extracellular fluid is the fluid in the blood as well as outside the cell, 20 percent is plasma and 80 percent is interstitial fluid.
The space containing interstitial fluid is called.
interstitium
