Bone- matrix calcified
cartilage- matrix is rubbery
blood- matrix is fluid?
Bladder, trachea, glands, kidneys, lungs, blood vessels, esophagus, skin surface, lines body cavities
Where is epithelial tissue found?
Active-requires cell energy (to drink. Used to bring fluids and solutes into the cell.
What is Pinocytosis?
Active transport mechanisms because they require cell energy (to eat). Example... Helps to destroy bacteria white blood cells.
What is Phagocytosis?
Rapid communication between body structures and control of body functions.
What is the function of the nervous tissue?
Intercellular material found between the cells.
liquid form is in the blood
In bone it is calcified hard and rigid like rubber
Where is matrix found?
Areolar, adipose, fibrous connective tissue, bone cartilage, blood, hematopoietic tissue
What are 7 types of connective tissue?
The clearage furrow begins to appear. Chromatids move away from the center of the cell.
What happens during Anaphase?
Chromosomes are aligned in the center of the cell and nuclear envelope and the nucleouls have disappeared.
What happens in Metaphase?
Like a waterfall=down
The movement of water and solutes thru a membrane as a result of a pushing force that is greater on one side than the other side by hydrostatic pressure.
Smooth=makes new cell membrane
Rough= transports newly made proteins made by ribosomes
What are two kinds of Endoplasmic Reticulum (ER)?
Endoplasmic Reticulum (ER)
What is a network of connecting sacs and canals that carry substances thru the cytoplasm from the nucleus?
What contains the genetic code instructions for making proteins which, in turn determine the cell structure and function?
1) Keeps the cell intact (like skin)
2) gateway between the fluid inside the cell and the fluid around it. Certain fluids are allowed to move thru the membrane and others are not.
3) It communicates with receptors
What are 3 functions of the plasma membrane?
Each cell in the body is surrounded by a thin membrane call the plasma membrane (not part of the cell.
What is the plasma membrane?
Endoplasmic reticulum (ER)
List the 8 organs (organelles)?
finger like projections of the plasma membrane (increase the curface are of a cell) for absorption.
Why are microvilli important?
What dense region of nuclear material programs the formation of ribosomes in the nucleus?
Diffusion of water across a permeable membrane but not solutes (already disolved in water)
What is osmosis?
Inherited condition from damage to the ion pump (chlorides) abnormally thick secretions in the airways and digestive system
What is cystic fibrosis?
The process by which substances scatter evenly themselves thru all the available space
What is diffusion?
Chemical processing and packaging center from the ER- flattened sacs stacked on one another near the nucleus.
What is the function of the golgi apparatus?
Active- required energy by the cell
Passive-doesnt require energy
What is the difference between active and passive transport?
Can be 10 layers found in areas that stretch such as the bladder or stomach.
Where do you find stratified transitional epithelium?
