BIO 168 Test #1 |79 Questions and Answers
Anatomy - -Science of structure (morophology)
-Cytology - -Study of cells
-Histology - -Study of tissues
-Physiology - -Science of function
-Characteristics - -Of living organisms (movement. Growth, reproduction, excretion,
respond to stimuli)
-Metabolism - -All the chemical reactions of living organisms
-Two types of metabolism - -Anabolism and catabolism
-Anabolism - -Assembling compounds and storing energy
-Catabolism - -breaking compounds down and releasing energy
-Homostasis - -maintaining a constant internal environment
-Non-living - -atoms-compounds-molecules-organelles
-Living - -cells-tissues-organs-system orgnisms
-Integumentary - -Components: hair,skin,nails
Functions: Protection, Sensation, Temperature Regulation, Barrier of pathogens
-Skeletal - -Components: Axial &Appendicular
Functions: support, protection, movement, blood cell production
-Muscular - -Components: Skeletal, smooth & cardiac
Functions: movement, heat, blood circulation
-Nervous - -Components: central & peripheral
Functions: communication, memory
-Endocrine - -Components: Glands & Hormones
Functions: Regulate Body Functions
-Cardiovascular - -Components: Heart & Blood Vessels
Functions: Body transport system
, -Lymph - -Components: Lymph glands and vessels
Functions: Immune response, garbage collector
-Digestion - -Components: Mouth, stomach, small & large intestine
Functions: Breakdown and absorb nutrients rid solid waste
-Respiratory - -Components: nose, trachea, & lungs
Functions: Exchange CO2 & O2
-Urinary - -Components: Kidneys & Bladder
Functions: Rid liquid waste regulate blood chemistry
-Male Reproductive - -Components: Testes & penis
Functions: Procreation & Recreation
-Female Reproductive - -Components: Ovaries & Uterus
Function: Procreation & Recreation
-Metric Equalivents - -in a water environment 1 ml = 1cc = 1 gm
-Atoms - -smallest unit of an element
-Protons - -positive charge, mass of 1
-Neutrons - -no charge, mass of 1
-Electrons - -negative charge, mass of 0
-Atomic number - -number of protons
-Atomic mass - -number of protons + neutrons (in nucleus) stable atoms have no net
charge (# protons = # electrons) unstable atoms - have a tendency to revert back to stable
atom
-Ions - -increase or decrease in # of electrons of stable atom
Increase results in a negative charge (Cl-)
Decrease results in a positive charge (Na+)
-Isotopes - -increase or decrease in number of neutrons changes mass but not charge
(some are radioactive) atomic bonds
-Ionic - -atoms combine and gain or lose electrons (very strong bonds) one atom gains
electrons (-), one looses electrons (+)
-Covalent bonds - -atoms combine and share electrons (very strong bonds)
Polar covalent bonds have a slight charge (water)
