A&P- Test 1

Dr. Cutler- South University- Chapters 1-3

QuestionAnswer
3 serous membranes 1. pleural (surrounds lungs) 2. Pericardium (covers heart) 3. Peritoneum (abdominopelvic organs & lines cavity)
visceral gut/internal organs
parietal wall
viscera pleura inside lungs
parietal pleura wall of lungs
viscera pericardium inside heart
parietal pericardium wall of heart
viscera peritoneum inside abdomen
parietal peritoneum wall of abdomen
4 quadrants URQ, ULQ, LLQ, LRQ
Upper Right Quadrant (URQ) Liver; Spleen
Lower Right Quadrant (LRQ) Small intestine; Appendix
Upper Left Quadrant (ULQ) Stomach
Lower Left Quadrant (LLQ) Large intestine
Matter = Atoms
Oxygen O
Carbon C
Hydrogen H
Nitrogen N
Atom smallest unit of matter -- retain the properties & characteristics of an element
Subatomic particles Electrons, Protons & Neurons
# of electrons on outer shell 8
# of electrons on inner shell 2
Chemical bonds forces of attraction (like magnets)
Valence shell furthest shell out
Hydrogen ("loose" friend) 1 electron; wants/needs 2 electrons
Molecule 2 or more atoms; share electrons
Compound contains 2 or more different elements
Ion atoms that lost or gained electron
Ion gained more negative
Ion lost more positive
ionization act of gaining/losing electrons
cation positively charged ions
anion negatively charged ions
Covalent bond sharing of ions - 3 types 1. Single 2. Double 3. Triple
Water is... Polar covalent molecule
Hydrogen bond VERY weak; kind of liked a 2 year old
Surface Tension results form H+ atoms sticking together
Chemical Bond new bonds formed/old bonds broken
Chemical bond; 3 components 1. Reactants (eggs and flour) 2. Products (cake) 3. Metabolism (mixing egg and flour)
Energy capacity to do work
3 types of energy 1. Potential = stored 2. Kinetic = released due to motion 3. Chemical = stored in bonds
concentration more particles present, more likely to collide
temperature particles move faster when heated up causing them to collide with enough force to disrupt the valence
synthesis 2 or more atoms combine to form new and larger atoms
anabolic body's synthesis reaction
decomposition splitting of larger molecules
catabolism usually exergonic - release more energy than absorb
Exchange both synthesis and decomposition in reaction together
Oxidation- reduction (OIL RIG) Transfer of electrons
oxidation loss
reduction gain
no carbon = inorganic
Water is .... a universal solvent
solution combination of solvent and solute
solvent dissolves another substance
solute thing being dissolved
normal blood pH 7.35- 7.45
Acidosis pH below 7.35
Alkalosis pH above 7.45
cytology study of cells
sex cells reproductive cells
somatic all body cells except sex cells
extracellular fluid watery/medium outside cell
Plasma membrane fluid mosaic (stained class window) outside of cell (phospholipid bilayer) selectively permeable separates external and internal
plasma membrane proteins integral periperal receptor carrier channel (transfer)
Glycocalyx sugary sweet outer coating (sweet tea)
Osmosis = water as solvent
Diffusion= salt or sugar as solute
Facilitated Diffusion: Osmosis water follows rock stats!! More rock stars the farther water will move
