CHS 200-final exam questions &
answers6
1918 Pandemic Influenza (spanish flu) - ANSWERS-spike of death in people 14-45 years old
caused 200-250 million deaths worldwide, 500,000 in US
fewer deaths in older people
preventative measure for Influenza - ANSWERS-creation of influenza vaccine
depending on the type of vaccine being produced, vaccine will contain three to four strains
dependent on availability of chicken eggs, which is used as growing medium for viruses
Influenza virus goes through antigenic drift every year - ANSWERS-which is why doctors think
we need a vaccine every year
Myxoma virus - ANSWERS-member of poxvirus group, small pox and is fatal disease in rabbits
H1N1 (swine flu) is no longer the killer it used to be - ANSWERS-because it is less virulent. It was
a circulation during the Spanish influenza and when you get an influenza vaccine, you are
getting an H1N1 vaccine too
Carcinogen - ANSWERS-substance that causes cancer
, free radical theory of aging - ANSWERS-oxygen molecules with an unstable electron move
around the cell, damaging cell structures as they go. example:lipids that are used to make up
cell membrane
free radicals - ANSWERS-chemical particles with an odd number of electrons- an extra unpaired
electron
Free radical prevention - ANSWERS-Vitamin A,C, E donating electrons and nutrients that
neutralize these free radicals
telomere theory of aging - ANSWERS-DNA sequences at the end of our chromosomes shortens
and evokes cell death
Location of Telomeres - ANSWERS-end of chromosomes
evidence of telomere theory of aging - ANSWERS-Hutchinson-Gilford progeria- a disease of
premature aging. Patients with this syndrome have shorter telomeres than unaffected
individuals which is an autosomal dominant inheritance pattern that causes premature aging.
Immune theory of aging - ANSWERS-Our bodies are less able to fight infection and cancer
tumors
Evidence to support immune theory of aging - ANSWERS-we all have cancer cells in our bodies
right now but our immune system takes care of them but as we age, the cancer cells are
allowed to grow undetected by our immune system because it weakens which is why the risk of
cancer increases with age
biological process of myocardinal infarction (heart attack) - ANSWERS-result of oxygen
starvation of the myocardium or the heart muscle
