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 & helps decide whether to have autopsy & whether a crime has been committed
1.1.d. What are examples of human body systems? 1.1.e. What organs make up the different body systems? Urinary “place for pee” Kidneys Ureters Bladder Urethra Nervous “full of nerves” Brain Spinal Cord Peripheral Nerves Sense organs (taste buds, ears, eyes, etc) Endocrine “secrete within” Pancreas Thymus Thyroid Pituitary Pineal Gland Adrenal Glands (“toward kidneys”) Ovaries/Test es Teeth/Tongue Salivary Glands Pharynx Esophagus (“eater within) Stomach Small Intestine Large Intestine (Colon) Rectum Liver Gall Bladder 1.1.f. What are examples of interactions between body systems? Urinary Nervous Endocrine Digestive Respiratory Cardiovascular Immune Skeletal Filters waste out of blood, removing cellular waste from all systems Tells other systems what to do via electrical signals (i.e. signal to poop) Secretes hormones that signal other systems to do things (i.e. hunger) Absorbs nutrients (small intestine) to feed all other systems Brings in oxygen needs by all cells and removes carbon dioxide waste Transportation systembrings nutrients, hormones, O2 to all systems, carries waste away Protects us by preventing, trapping and killing pathogens (“disease starters”) Provides structural support, protects soft organs (i.e. heart) & makes blood cells Nasal Cavity Pharynx Larynx Trachea (“air tube”) Bronchus Bronchiole (“little bronchus”) Alveoli*** (“hollow”) ***then back the opposite direction Digestive Respiratory Cardio. “heart & small vessels” Atria (“entrance halls for blood”) Ventricles (“bellies” that pump out blood) Veins Venules (little veins) Arteries Arterioles (little arteries) Capillaries (“hairs”place arteries turn to veins) Erythrocytes (“red cells”) Bone Marrow Thymus Spleen Lymph Nodes (“water knots”) Tonsils Leukocytes (“white cells”) Appendix Immune
1.1.g. What might be the consequence of malfunctions in any of the body systems? Urinary Nervous Endocrine Digestive Respiratory Cardiovascular Immune Skeletal Waste will build up, killing person (kidney failure) unless they have dialysis Miscommunication causes problems like paralysis, Parkinson’s, epilepsy, etc People can experience gigantism, thyroid disorders, clotting disorders (hemophilia), etc Celiac disease, Crone’s disease, etc can interfere with absorption of nutrients Cystic fibrosis or infections can cause fluid build-up, person can drown Vision loss or limb loss if blood doesn’t circulate to those areas (like in diabetes) Autoimmune disorders if it’s overactive, inability to fight disease if it’s underactive Can’t fight disease if not making WBCs, can’t circulate oxygen if not making RBCs
1.1.h. What is a system? Parts that work together to do a job (i.e. a SCHOOL system, a BODY system, a COMPUTER system) In the case of human body systems, similar cells make up tissues and the tissues form organs, which work together. 1.1 i. Are all sources of information accurate and reliable? Sources are listed as citations in a bibliography. Primary sources are firsthand accounts (Darwin’s Origin of Species & secondary sources reference primary sources (modern biology books). We should always cite all...
