blood path through heart-left

pulmonary vein


left atrium


mitral valve

aortic vale


aorta-out to body

nervous system contains 2 ?



Pheripheral nervous system (pns)


central nervous system(cns)

cns

brain and spinal cord



pns

cranial and spinal nerves that extend beyond cns





  • autonomic
  • sensory somatic nervous system

autonomic

(PNS)



  • controls automatic body functions
  • ex:Heartbeat
  • includes sympathetic nerves (excited or scared)
  • parasympathetic nerves(eating or sleeping)

sensory-somatic nervous sytem

(PNS)



  • 12 cranial nervs
  • 31 pairs of spinal nerves & associated gangila
  • controls voluntary actions (talking &walking)

gangila

collections of nerve cell bodies

dendrites

they receive stimuli from internal & external environment and bring back to nerouons for interpetation

phagocytosis

engulfing of pathogens by white blood cells

perforins

natural killer cells produce this


-pore forming proteins that target virus and cancer cells


-causes cells to lyse

interferons

body's response to viral infection


-prevent cells from replication after 7-10 days


-activate nk cells

chemotaxis

leukocytes respond to damaged body tissue


-cytokines-chemical messengers that are released by damaged cells play a roll

diapedesis

process of WBC squeezing through capillaries slits in response to cytokines


(followed by cellular adhesion molecules guiding white blood cells to site of damage)

active immunity

-vaccine


-after vaccine body stimulates actual infection by pathogen stimulating body to produce antibodies for future protection

passive immunity

body does not make own antibodies


-receives them directly (nursing)

cell medicated immunity

t cells (lymphocyte that triggers the action of other lymphocytes) are primarily responsible for recognizing nonself cells

natural selection

some individuals of a species are better able to survive in their enviornment and able to reproduce others

alleles

every gene exists in different forms

adaption

mutations in alleles allowing better survival




(natural selection produces it)




adaption is end result

microtubules

cellular tracks that, during mitosis, form the miotic spindle. spindle helps organize and segregate the chromosomes during cell division.

centrosomes

microtubules-organizing centers that help to form and organize the mitotic spindle during mitosis

cell differention

produces more specilized cell


can happen as adult or embryo




ex:stem cell

cell replication

g1


s


g2

g1


  • dna helix unwinds
  • rna base pairs with partners to form messenger rna strand MRNA
  • helix closes, mrna exists nucleus, and takes info to ribosomes


s (synthesis)


  • dna helix unwinds (help from enzymes)
  • this breaks hydrogen bonds and seperates from base pairs (but not backbone)
  • pair with new complementary bases -then synthesized to new complementary strand -dna ploymerase enzyme helped
  • other stand from original helix going through same thing
  • 2 new strands

g2

continued protein synthesis and cell growth preparation for cell division

mitosis

prophase


metaphase


anaphase


telophase

prophase


  • spindle fibers form
  • centrioles move to opposite sides
  • nucleaur membrane disappears

metaphase

  • chromosomes align midway along spindle fibers

anaphase

  • chromosomes begin to separate from daughters
  • cytokinesis begins

telophase

  • identical sets of chromosomes are at opposite ends of the cell
  • spindle fibers disappear
  • nuclear membrane reappears
  • cytokinesis completes

cytokinesis

seperateing the two sets of chromosomes into different cells

meosis

  • prophase I
  • metaphase i
  • anaphase I
  • telophase I
  • prophase II
  • metaphase II
  • anaphase II
  • telophase II

prophase 1

  • homologous chromosomes condense and link (process-forming tetrads)
  • crossing over or recombination occurs

metaphase 1

  • homologous chromosome move to metaphase plate

anaphase 1

  • homologous chromosomes separate
  • sister chromotaids stay together

telophase 1

  • cytokinesis has occured
  • 2 haploid daughter cells are result

haploid

single set of chromosomes

diploid

cells that contain two sets of chromosomes

prophase 2

  • brief stage spindle fibers begin to reappear
  • centrioles move to opposite of poles

metaphase 2

sister chromtaids align at new metaphase plate

anaphase 2

sister chromatids separate again

telophase 2

4 haploid cells result after cytokinesis

sister chromatids

two identical copies if dna

meoisis and mitosis occur?


  • mitosis occurs to replace old cells in all cell types
  • meiosis occurs in gametes to bring about genetic variation among offspring

photosynethis

carbon dioxide + water + sunlight= Glucose + Oxygen (atp)


atp is fuel for cell from co2 and water

cellular respiration

glucose+oxygen=carbon dioxide+water+energy



  • transffered to krebs cycle where more atp is made
  • cell uses mitochondria to produce atp
  • co2 is made

dna repair process

  1. dna polymerase proof reads
  2. mismatch repair
  3. excision repair-damaged cells (exposure)

germ cells

reproductive cells that pass genetic info on to offspring

electromagnetic waves

waves of radiation that are characterized by electric and magnetic fields

wave lengths s-l


  • gamma ray
  • xray
  • ultraviolet ray
  • visible
  • infrared
  • microwave
  • radio

catalysts

control rate of chemical reaction, or reactions in which atoms react to come stable



  • *promoters-increase reaction (by lowering activation energy) *
  • inhibitors-decrease reaction

reaction rates

depend on frequency of contact of reactants with the catalysts


(may be artificially accomplished by increasing substrate (molecular surface acted upon by enzyme)
