1The Circulatory System And the Forensic Implications of Human Anatomy
2The Circulatory System: Because blood is so vital to sustaining life, this system is very important in a death investigationWhat it does:Pumps blood throughout the body, delivering oxygen and nutrients to cellsWhen cells absorb O2 from blood, they release CO2 and other wastes into the bloodThese wastes are then released into other organs - such as the kidneys and liver - for elimination
3Organs of the Circulatory System The heartBloodArteriesVeinsCapillaries
6The system is divided into two pathways: Systemic PathwayPulmonary PathwayThe heart pumps oxygenated blood from the left atrium to the left ventriclethrough arteriesThis blood is exchanged through capillaries to reach each cell in your bodyCells absorb oxygen throughout body and release wastesVeins carry deoxygenated blood, CO2, and other wastes back to the heart (right atrium)Veins carry deoxygenated blood back to the right atrium of the heartThis blood is pumped through the right ventricle and goes to the lungs through the pulmonary arteriesThe lungs have capillaries and tiny alveoli where the blood becomes oxygenatedThe oxygenated blood flows from the lungs and back into the left ventricle of the heart
7Warm-UpSpend the next 5 minutes looking through your portfolios – especially the guided notes.On your portfolio, choose a spot and write the date (4/29/13)Then, write at least 3 questions you may have about anatomy or forensic anthropology – we will review before the quiz
8Forensic Anthropology Review Take out your Forensic Anthropology packets from 4/15/13You will be getting into your expert groupsSpend a few minutes reviewing your article and questionsTogether, you will create a poster to present to the rest of the classAs each group presents, you must take notes – this will help you on the quiz!
9Teaching Checklist – Stuff to Include on Your Posters: Know your vocabularyBe ready to explain the main take-aways from your articleWhat methods do forensic anthropologists use?What kinds of observations do they make?Be able to explain diagrams and chartsDiscuss the questions, confusions, or points of disagreement from your expert groups – your home group members may have the same questions or disagreementsShow your home group members how you answered your questions, not just the answersWhat was your evidence and reasoning?
10Take some time right now to write your observations about these three different types of muscles in the human body. We will learn why they each look different and how they function during next class.ABC
