Presentation Transcript


By law, deaths that occur under the following circumstances must be investigated:

  • Violent crime, suicide, or accident

  • Within 24 hours of entering a hospital or as a result of surgery

  • A natural death when a doctor is not present or the patient is not under the care of a medical facility

  • Occurs in police custody or in a correctional facility

  • Results from a communicable disease that may pose a threat to public health

Autopsy basics
Autopsy Basics

  • Performed by a forensic pathologist – a medical doctor who is trained to identify why and how someone died and present those finding in court.

  • At the scene – Postmortem interval is estimated (amount of time since death)

  • In the ME’s office:

  • Determine cause, manner & mechanism of death


1) A Y-incision is made on the torso to expose the inner organs


  • Each organ is removed, weighed, carefully observed, and a sample is taken and sent to appropriate people

    • Toxicology

    • Histology

    • Neuropathology

    • Serology

What to look for
What to look for:

  • Blood for DNA – ME’s collect blood from arteries for identification and toxicology (determines drug & alcohol content). Dried blood on skin could be from perpetrator

  • Semen – If sexual assault is suspected

  • Hair – a “control sample” is collected to compare to unknown hairs found at the scene

  • Tissue – Tissue samples are sent to histology for analysis

  • Fingernails – Could contain DNA from perpetrator if a violent crime

  • Bite Marks – Images sent to forensic odontologists

Close up
Close Up

  • Everything is put back in place and a “baseball stitch” Is used to close back up.

  • A report is made….. And yes…. They have to use complete sentences and punctuation counts.

Now you try!

  • Go to: - You must use internet explorer!

    Describe in 8-10 sentences the procedure of an autopsy. Points counted off for missing sentences or short sentences obviously used to fill space.

    Do 2 autopsies then have the program email me the results:

Biomolecules review
Biomolecules Review!

  • Carbohydrate

  • Proteins

  • Lipids

  • Nucleic Acids


  • Account for more than 50% of the dry mass of most cells, and are instrumental in almost everything organisms do. We will cover these in great detail.


  • Monomer- monoglycerides and fatty acids

  • Polymer-Triglycerides: Glycerol, and 3 Fatty acid chains

  • Phospholipids

  • Jobs in the body:

    • Long-term energy storage

    • Makes up cell membranes

    • Sending messages to distant cells (hormones)

    • Insulation and protection of us and our cells!

Carbohydrates sugar
Carbohydrates: (sugar!)

  • Main source of energy for life on earth

  • Monomer-"Simple sugars" monosaccharides (glucose, ribose)

  • Jobs in the body:

  • Immediate energy

  • Labeling a cell

  • Cell walls in plants

Nucleic acids
Nucleic Acids:

  • Monomer: Nucleotide

    • Composed of a nitrogenous base, a sugar, and a phosphate group.

    • Combine to form DNA

  • Polymer, DNA, RNA
