Mystery Study Questions
1.1. The Mystery Study Guide
1.1.a. What causes death? The failure of one system can cause failure of next ending in lack of brain activity 1.1.b. What clues may be found at a scene of a mysterious death that may help to determine the cause of death? Vomit, blood, fingerprints, DNA, saliva, bite marks, bullets, poison, etc 1.1.c. If someone was interested in a career with responsibility to determine the cause of death, what careers should he or she consider and investigate? Forensic Pathologist (Medical Examiner) Toxicologist Coroner Medical doctor that primarily does autopsies and determines cause of death PhD (usually) who tests body fluids (blood, vitreous humor, urine) for presence of toxins & medications to help determine cause of death Elected official that works with police & …show more content…
How do principles of engineering apply to heart structure and function? The heart is a pump, just like artificial pumps created by engineers. Biomedical Engineers create things like artificial heart valves & pacemakers to help treat heart problems.
2.3 The Heart at Work Study Guide by Hisrich
2.3.a. In what ways can technology be used to collect and analyze cardiovascular data? Thing measured Blood pressure Tool used Sphygmomanometer “pulse measurer” Heart rate Electricity within heart Timer EKG Used to find beats during 10 seconds (then multiply by 6 for bpm) Electrodes on skin pick up current and show graphically Used how Determines systolic and diastolic arterial pressure
2.3.e. What is an EKG? 2.3.f. How can an EKG be used in the diagnosis and treatment of heart disease? EKGs, or electrocardiographs (“electricity heart pictures”) measure the heart’s electrical activity and display it in the form of a picture: P wavesignal passes from SA node (sinoatrial node) to AV node (atrioventricular node), moving across atria QRS intervalsignal passes from AV node through Purkinje fibers & the ventricles contract T wavethe ventricles repolarize & the heart is relaxed
