  3. Human Body Systems This slide presentation is meant to help you study the major systems of the human body. Use it as an introduction or as a review. Follow the instructions as you move along to explore and learn. You can go through the entire program slide by slide, or you skip to focus on any one system.

  4. http://www.parentingpress.com/pics/sock_cvr.jpg Believe it or not, you are organized! • The main levels of organization are… • Cells, Tissues, Organs, Organ Systems, and You (the Organism).

  5. Can you identify & label the 3 levels of organization shown here? Well, at least your body is!

  6. Levels of OrganizationThe Human Body has several “layers” of organization beginning with the simplest and becoming more complex. Answers to previous slide: cell, tissue, organ (small intestine). http://www.bmb.psu.edu/courses/bisci004a/chem/levels.jpg

  7. By the way, is your room “organized” like this!?!?

  8. Here They Are: Your Body Systems (Part 1). http://www.agen.ufl.edu/~chyn/age2062/lect/lect_19/147a.gif

  9. And Your Body Systems (Part 2) http://www.agen.ufl.edu/~chyn/age2062/lect/lect_19/lect_19.htm

  10. So Let’s Begin!

  11. DR. I.I.L. MCSNEER Presents…Your Digestive System

  12. Your digestive system is like a complicated chemical processing plant, and performs many functions.

  13. What major tasks does your digestive system help you accomplish?

  14. Your Digestive System… …breaks down food into molecules the body can absorb. …passes these molecules into the blood to be carried throughout the body. …works to eliminate solid wastes from the body.

  15. The Parts of Your Digestive System How well do you know them?

  16. Label the parts of your digestive system on your handout; then correct them using the following slide.

  17. Parts of Your Digestive System

  18. Now for the Digestive Journey

  19. The Digestive Journey Digestion begins in your mouth with action of your teeth and tongue (mechanical digestion) and your salivary glands (chemical digestion). The salivaryglands produce enzymes that are mixed with the food, breaking down the starches. Peristalsis is the muscular action that moves the food through the esophagus and into your stomach after you swallow.

  20. Your Stomach The food moves into your stomach, which contains chemicals such as hydrochloric acid and pepsin. Pepsin breaks proteins, and other enzymes break down fat. Your stomach gradually releases these materials into the upper small intestine (duodenum), where digestion is completed. Your stomach also has a thick coating of mucus to protect it form the acids and to keep it from digesting itself!

  21. By the way, your stomach really does look like a muscular bag!

  22. Your Liver, Pancreas, and Gall Bladder Located in the upper portion of your abdomen, your liver is the largest and heaviest organ of your body. It is like a busy chemical factory that plays many roles. For example, your liver breaks down many substances and toxins, and produces bile- a substance that helps break down fat. The bile flows from the liver into the gall bladder, where it is stored until needed. The pancreas lies between the stomach and the duodenum and produces enzymes that flow into the small intestines, helping to break up complex starches, proteins, and fats.

  23. Your Small & Large Intestines After the solid food has been digested the fluid remaining is called chyme When it is thoroughly digested it passes through an opening (called the pylorus sphincter) into the small intestines. In the small intestines all the nutrients are absorbed leaving undigestible wastes. These wastes pass into the large intestines, where water is removed. Then the wastes are stored in the rectum until they are released by the anus.

  24. Cross Section of Your Intestines The Villi add surface area to increase absorption of food and nutrients. On the left you see how the villi line your small intestines, and on the left you see 1 villi with its capillaries.

  25. It’s a (Intestinal) Gas, Baby! The human large intestine, or colon, is home to many microorganisms, such as the bacterium Escherischia coli (E. coli). Certain foods contain large amounts of carbohydrates that our digestive enzymes cannot break down. When these carbohydrates reach the large intestine, our gut microbes respond by "having a party“ (reproducing rapidly, giving off gases such as methane and hydrogen sulfide as natural by-products of their activities). This is the cause of the discomfort and flatulence associated with eating beans, cabbage, and other gas-promoting foods. Fortunately for gas sufferers, the enzymes that enable our microbes to break down complex carbohydrates are now available in pill form. If these are taken before a meal, the enzymes break down the carbohydrates in the small intestine so that they can be absorbed by the body before they reach the hungry throngs of bacteria living in the colon.

  26. DR. I.I.L. MCSNEER Presents…Your Respiratory System

  27. The Functions of Your Respiratory System Your respiratory system moves oxygen from the outside environment into your body. It also removes carbon dioxide and water from your body (this image shows all the tiny bronchioles that carry air into your alveoli for gas exchange).

  28. The Path of Air Please label the parts of your respiratory system on your handout. Can you describe the path that air takes as it enters and leaves your body?

  29. Check Your Answers Here.

  30. How You Breathe 1: The Diaphragm

  31. How You Breathe 2: The Alveoli

  32. The Respiratory and Circulatory Systems: Working Together. Working together the respiratory and circulatory systems form the cario-pulmonary system, which is an integral connection between the heart and lungs.

  33. The Cardio-Pulmonary System

  34. Respiratory Disease: Pneumonia Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus. Pneumonia can also be caused by inhaling vomit or other foreign substances. Web Sources and Resources www.medimagery.com/Respiration/ lungs.html

  35. Respiratory Disease: Lung Cancer The cancerous lung (right) shows how much damage smoking can do over time to your respiratory system.

  36. X-Rays can help detect cancer, and surgery and radiation are some treatments for the disease. Web Sources and Resources www.smm.org/heart/lessons/ lesson11.htm

  38. DR. I.I.L. MCSNEER Presents…Your Integumentary System (It’s Your Skin!)

  39. Your skin covers your body and prevents the loss of water. It protects the body from injury and infection. The skin also helps to regulate body temperature, eliminate wastes, gather information about the environment, and produce vitamin D. The skin is organized into two main layers, the epidermis and the dermis.

  40. Can You Name the Parts of Your Skin?

  41. Skin Anatomy

  42. What is Botox? Botox is the commercial name given to a toxin which is produced from botulism toxin. a medical protein that is injected into a muscle to cause temporary (months) paralysis of that muscle. This helps prevent the appearance of wrinkles.

  43. With Botox will everyone look the same? What do you think?

  44. DR. I.I.L. MCSNEER Presents…Your Immune System

  45. Your Immune System Your Immune system protects you from foreign invaders. Special cells react to each kind of pathogen with a defense targeted specifically at that pathogen. http://www.nobel.se/medicine/laureates/1996/illpres/introduction.html

  46. Your Immune System Has Many Specialized Cells! White blood cells that target specific pathogens are called lymphocytes. There are two major kinds of lymphocytes—T cells and B cells. A major function of T cells is to identify pathogens by recognizing their antigens. Antigens are molecules that the immune system recognizes as either part of your body, or as coming from outside your body. B cells produce chemicals called antibodies.

  47. How Your Immune System Works Our immune system protects us against threats. These include viruses, bacteria and parasites causing infectious diseases, from ordinary flu to full-blown malaria. The white blood cells of the defense system are produced in the marrow of our bones. The cells are carried in the blood to specialized organs, where they develop and communicate to launch immune responses against infections. • http://www.nobel.se/medicine/laureates/1996/illpres/introduction.html

  48. DR. I.I.L. MCSNEER Presents…Your Lymphatic System

  49. The Functions of Your Lymphatic System Your lymphatic system and the cardiovascular system are closely related structures that are joined by a capillary system. The lymphatic system is important to the body's defense mechanisms. It filters out organisms that cause disease, produces certain white blood cells and generates antibodies. It is also important for the distribution of fluids and nutrients in the body, because it drains excess fluids and protein so that tissues do not swell up. http://www.acm.uiuc.edu/sigbio/project/updated-lymphatic/node_p2.gif
