Important areas related to health
Medical care
Biomedical research
Public health
Health care
Longevity
Medical care
Professions dedicated to the treatment and prevention of illness
Heavy reliance on technology:
Diagnostic tools (e.g., blood tests, scanning)
Treatment (e.g., surgery)
Pharmaceuticals (e.g., vaccines, antibiotics)

Health Care
Umbrella term that encapsulates many components
Includes health care policies and insurance
Includes patient records
Includes ancillary services (mental health, physical therapy, occupational therapy, holistic care)
Highly politicized due to $$$

14
Edward Jenner (1749-1843)
Father of immunology
Vaccination for smallpox
Smallpox highly lethal, very disfiguring
Noticed that milkmaids who contracted coxpox (mild, related type of pox) didn’t contract smallpox
Exposed a little boy to cowpox, then injected him with smallpox – did not contract smallpox
1980 – Smallpox eradicated

Significant impact on the family structure
Fewer births
Mothers older, more financially stable
More infertility problems

Assistive Reproductive Technologies
IVF – In vitro fertilization – egg fertilized by sperm in a petri dish, implanted back in mother
Louise Brown, born July 25, 1978
1st “Test Tube Baby”
Introcytoplasmic Sperm Injection
Remove the egg, inject sperm directly into the egg, transplant
Used in cases of male infertility
Cloning
Producing an animal in a laboratory that is an exact genetic copy of another
Make a clone activity:

Is it a clone or not game:

32
Potential uses of cloning:
Cloning research animals to study disease
Cloning stem cells to repair the human body
Cloning animals for pharmaceutical development
Reproducing extinct or dead species or animal (pets, humans)
Risks:
High failure rate
Development problems (large offspring syndrome)
Abnormal gene expression
Should we clone humans?
Stem Cells
Undifferentiated embryonic or adult cells
Used to create differentiated cells for therapeutic purposes
