  1. About Science Prof Online PowerPoint Resources • Science Prof Online (SPO) is a free science education website that provides fully-developed Virtual Science Classrooms, science-related PowerPoints, articles and images. The site is designed to be a helpful resource for students, educators, and anyone interested in learning about science. • The SPO Virtual Classrooms offer many educational resources, including practice test questions, review questions, lecture PowerPoints, video tutorials, sample assignments and course syllabi. New materials are continually being developed, so check back frequently, or follow us on Facebook (Science Prof Online) or Twitter (ScienceProfSPO) for updates. • Many SPO PowerPoints are available in a variety of formats, such as fully editable PowerPoint files, as well as uneditable versions in smaller file sizes, such as PowerPoint Shows and Portable Document Format (.pdf), for ease of printing. • Images used on this resource, and on the SPO website are, wherever possible, credited and linked to their source. Any words underlined and appearing in blue are links that can be clicked on for more information. PowerPoints must be viewed in slide show mode to use the hyperlinks directly. • Several helpful links to fun and interactive learning tools are included throughout the PPT and on the Smart Links slide, near the end of each presentation. You must be in slide show mode to utilize hyperlinks and animations. • This digital resource is licensed under Creative Commons Attribution-ShareAlike 3.0: • http://creativecommons.org/licenses/by-sa/3.0/ Alicia Cepaitis, MS Chief Creative Nerd Science Prof Online Online Education Resources, LLC alicia@scienceprofonline.com QUICK TRICK!: I start every class by displaying a group of images on the next slide and asking the students: 1. What would be your caption for these images? 2. How do these images relate to today’s lecture?

  2. Homeostasis and Pathology Anatomy Lecture Series 2 How do our bodies maintain a stable internal condition? From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com Anatomy and Physiology Lecture PowerPoint's by A. Cepaitis

  3. Warning! These actions can cause disruption to homeostasis From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com

  4. Homeostasis • Being alive requires a delicate balance of physiology within and between the cells and organs of human bodies. • Homeostasis is the maintenance of a stable internal condition despite changes to the external environment • Many feedback loops control homeostasis throughout the body.

  5. Examples of Homeostatic Conditions for Humans • Body temperature: normal range98° F - 100°F • Heart rate: normal range60 bpm – 100 bpm • Blood and Urine pH: • Blood normal range 7.35 – 7.45 • Urine normal range 4.50 – 8.00 From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com

  6. Homeostasis Out of Control Frostbite. Color/wiki.. High fever. Serif Photos. • Body temperature: • Hypothermia: (<86°) skin blue, puffy, stupor, numbness in limbs • Hyperthermia: (>104°) nausea, headache, dizzy, feels hot • Heart rate: • Bradycardia: (<60 bpm) dizzy, tired, confused, faintness • Tachycardia: (100-400 bpm) pain in chest, dizzy faintness, vision changes • Blood and Urine pH: • Blood acidemia: (<7.35) lethargy, stupor, chest palpitations, headache • Blood alkalosis: (>7.45) vomiting, muscle weakness, muscle spasms • Urine acidosis: (<4.5) decreased urination, confusion, fatigue, increased breathing • Urine alkalosos: (>8.0) painful, urgent or frequent urination Dizziness.

  7. Pathology • Pathologies are conditions that disrupt homeostasis beyond the immediate control of a feedback system in the body. From Crash Cars Blog. • Conditions that cause disruption: • Genetic mutations • Infection by pathogens • Environmental exposure • Congenital defects • Accidents • Tumor growth or metastasis • Malnutrition • Autoimmune problems Stage Diving. Marcus Olovsson from Tumblr From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com

  8. Pathological Processes • Genetic mutation • Example: Cystic Fibrosis • this disease primarily affects the respiratory and digestive systems and is fatal without daily treatments. • inherited mutations to one gene (CFTR) create abnormal ion channels in all cells. • Infections can be caused by a variety of pathogens including: • Prions (mad cow disease) • Viruses (common cold) • Bacteria (cholera) • Protozoans (giardasis) • Fungus (yeast infections) Cystic fibrosis Gene Location. NCBI Bovine prion.. NSF Cholera Bacteria. NIH From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com

  9. Pathological Processes Environmental can be caused by a variety of exposures to toxins, allergens, and extreme weather. Pollen grains. City of Houston, TX Lead Paint Exposur. Hawaii Dept. of Health Congenital disorders caused by problems that form during development of a fetus. The defect is not always detectable at birth. Patent Foramen Ovale occurs when a normal fetal hole in the heart does not close. PFO. NEJM. From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com

  10. Pathological Processes Accidents can cause cuts, burns, broken bone, head injuries, loss of blood, shock, and muscle tissue damage among other problems. Shattered fibula and tibia. Wellcome Library Tumors can be benign or malignant. Malignant tumors can spread to other tissues in the body to cause further damage. Benign tumors do not metastasize and are dangerous only when they interfere with organ function due to size. Pancreatic cancer metastasized to the liver. Wiki Commomn From the Virtual Anatomy and Physiology classroom on ScienceProfOnline.com

  11. Pathological Processes Malnutrition caused by the absence or excess of one or more essential nutrients in the diet. -Iodine deficiency: creates thyroid problems and goiters -Vitamin A overdose: nausea, vomiting, headache, blurred vision Malnurished Afgan Child. US Air Force Autoimmune Disorderscaused by the immune system mistakenly attacking healthy tissue in the body. Most autoimmune diseases are chronic and symptoms vary according to the type of tissue that is attacked. Goiter caused by an autoimmune disease.
