Essentials of A&P - Ch 3 & Ch4

TermDefinition
Diffusion passive transport where a solute travels from an area of higher concentration to an area of lesser concentration with the gradient.
Osmosis passive transport where water (solvent) travels thru a selectively permeable membrane when a concentration gradient is present.
Facilitated Diffusion Carrier-mediated passive transport is a variation of diffusion in which a carrier molecule helps a substance move across the membrane
Filtration pressure is applied to force water and its dissolved materials across a membrane.
Active Transport (3 types) 1. Active Transport Pumps 2. Endocytosis 3. Exocytosis
Pinocytosis liquid brining liquid is brought inside the cell using ATP.
Active Transport Pumps require ATP energy to move substances against the concentration gradient
Cell Membrane surrounds the cytoplasm and provides a protective covering.
Chromatin material found in the nucleus that contains the DNA.
Mitochondria power houses of the cell
Lysosomes vesicles containing powerful hydrolytic enzymes that take care of cleaning intracellularp
Golgi Apparatus receives protein from endoplasmic reticulum and processes/ stores in
Cilia short, microscopic located on the outside surface
Mitosis produces replacement cells, asexual cellular reproduction.
Meiosis produces gametes that provide half of the chromosomes.
Mitosis, Benign Tumors grow slowly and push healthy cells out of the way. NOT life-threatening.
Mitosis, Malignant Tumors grow rapidly and invade, health cell tissue.
Mitosis, Metastasis parts break off and travel thru the blood or lymph system and start tumors in other parts of the body.
Viruses infectious particles that have a core containing genetic material surrounded by a protective protein coat called a capsid.
MRSA Methicillin-resistant Staphylococcus aureus
VRE Vancomyocin-resistant Escheria Coli
Cells fundamental units of living organisms.
ATP adenosine triphosphate
Cytokinesis division of the cytoplasm and organelles.
Bacteria simple one-celled organisms without a nucleus or many organelles
Protozoa one celled organism that can cause disease thru ingestions or insect bites.
