12 Skeletal System Information Appendicular System126 bonesAxial System80 bonesTotal Bones = 206
13 Types of Bone Tissue spongy bone tissue – strong, lightweight tissue found inside the bone -makes up most of the short, flat, irregular bones, and ends of long bones
14 Types of Bone Tissue compact bone tissue -tough, hard outer layer of bone -part of the body called the skeleton
15 3 Types Of Joints joints – place at which two parts of the skeletal meet immovable joints - lock bones together like puzzle pieces (skulls bones) slightly movable joints- are able to flex slightly (ribs are connected to sternum) freely movable joints - allow body to bend and to moveBrainpop - Joints15
16 Types Of Freely Moveable Joints Hinge- arm moves up and downPivot – neck moves from side to sideBall & Socket – rotating arm in a circleGliding- all joints glide16
17 Interesting FactsThe longest bone in your body is the bone above your knee, the thighboneYour funny bone isn’t a bone at allWhen you were born, you had more than 300 bones. By the time you stop growing, you’ll have 206At the end of adolescence your bones stop growingYour bones are living. They grow as you get older
18 Conditions of the Skeletal System OsteoporosisBones become fragile and more likely to breakOsteoarthritisJoint disorder where the cartilage is wearing away
19 Muscular Systemmuscular system – muscles of the body that, together with the skeletal system, function to produce movement
20 The muscular system is made up of… musclesandtendons
21 How many muscles do you have? You have about 650 muscles in your bodyYour muscles make up half of your body weight
22 Functions of the Muscular System Holds bones together so that movement can occurHelps maintain stable body temperature (homeostasis)Helps maintain posture
23 3 Types of MusclesSmooth Muscles – muscle that performs involuntary movement and is found inside certain organs, such as the stomachinvoluntary – movement without conscious controlCardiac Muscle – involuntary muscle that makes up the heartSkeletal Muscles - muscle that perform voluntary movement and are attached to the skeletonvoluntary – movement at will23
24 Why do I need tendons? Try This... -tendons attach muscles to bone and help the body movefeel your tendon right above your heel in the back ofyour leg*this is the thickest tendon in your bodyTry This...
25 Ways to keep my muscles strong… Eat foods from the meat group every day (they are high in protein which helps to build strong muscles)Exercise every day
26 Your Digestive SystemBrainpop - Digestive System
27 Your digestive system is like a complicated chemical processing plant, and performs many functions
28 Two Types of Digestion: mechanical and chemical Mechanical digestion: breaking, crushing, mashingChemical digestion: Saliva, Gastric acids
29 What major tasks does the digestive system help accomplish?
30 Your Digestive System… -breaks down food into molecules the body can absorb-passes food molecules into the blood to be carried throughout the body-works to eliminate solid wastes from the body.
31 The Parts of Your Digestive System How well do you know them?
32 Parts of Your Digestive System Brainpop - Appendix
34 The Digestive JourneyDigestion begins in your mouth with action of your teeth and tongue and your salivary glands.Food then moves through the esophagus and into your stomach after you swallow.
35 The food moves into the stomach. Your StomachThe food moves into the stomach.The stomach gradually releases materials into the upper small intestine, 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!
36 Your stomach really does look like a muscular bag!
37 Your Small & Large Intestines When food is thoroughly digested it passes through an opening into the small intestines.In the small intestines all the nutrients are absorbed leaving undigestible wastes.The indigestible 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.
39 The Functions of the Respiratory System -moves oxygen from the outside environment into the body-removes carbon dioxide and water from the body
40 Respiratory SystemBrainpop - Respiratory System
41 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 Resourceslungs.html
42 Respiratory Disease: Lung Cancer The cancerous lung (right) shows how much damage smoking can do over time to your respiratory system.
43 X-Rays can help detect cancer, and surgery and radiation are some treatments for the disease. Web Sources and Resourceslesson11.htm
44 Excretory/Urinary System -collects wastes produced by cells and removes these wastes from your body-removal process is known as excretion-kidneys are the major organs of the excretory system-kidneys filter your blood and remove urea (excess water, and some other waste materials from the blood)-filtering process produces a watery fluid called urineYucky: Pee
45 Excretory/Urinary System Brainpop - Urinary System
46 Excretory/Urinary System excretory system is a system that connects to the digestive systemthe main organs of the excretory system are the bladder, kidneys, ureters, urethra, and nephrons
47 Kidney StonesKidney stones are created when certain substances in urine -- including calcium and uric acid -- crystallize and the crystals clump together. Usually, they form in the center of the kidney, where urine collects before flowing into the ureter, the tube that leads to the bladder. Small stones are able to pass out of the body in the urine and often go completely unnoticed. But larger stones irritate and stretch the ureter as they move toward the bladder, causing excruciating pain and blocking the flow of urine. Rarely, a stone can be as large as a golf ball, in which case it remains lodged in the kidney, creating a more serious condition
48 Cardiovascular/Circulatory System Brainpop - Circulatory System
49 The circulatory system is responsible for transporting blood (which carries oxygen and food for the cells) throughout the bodyWeb Sources and Resources Usborne Human Body: Quicklinks
50 Parts of the Cardiovascular/Circulatory System HeartBloodBlood Vesselsarteries – carry oxygenated blood from the lungs to the rest of the bodyveins – carry deoxygenated blood back to the lungscapillaries
51 Blood-Blood is the fluid of life, transporting oxygen from the lungs to body tissue and carbon dioxide from body tissue to the lungs-Red blood cells and white blood cells are responsible for nourishing, cleansing, and protecting the body-Approximately 55 percent of blood is plasma, a straw-colored clear liquid-The liquid plasma carries the solid cells and the platelets which help blood clot-Without blood platelets, you would bleed to deathBrainpop - Blood
53 Your Heart is a Very Muscular Organ! Heart DissectionsHuman heartBeef heartBeef heart undissectedYour Heart is a Very Muscular Organ!Brainpop - Heart
54 Artificial HeartsThe action of the artificial heart is entirely similar to the action of the natural heart. There is, however, one huge difference: the natural heart is living muscle, while the artificial heart is plastic, aluminum, and Dacron polyester. As a result, the artificial heart needs some external source of "life." An external power system energizes and regulates the pump through a system of compressed air hoses that enter the heart through the chest. Since the system is cumbersome and open to infection, the use of an artificial heart is meant to be temporary.
56 Integumentary System -covers the body and prevents the loss of water -protects the body from injury and infection -helps regulate body temperature, eliminate wastes, gathers information about the environment
57 Integumentary System -1st line of defense against infection -organs/structures of the integumentary system include the skin, sweat glands, hair, and nails
59 Your Immune System -fights foreign invaders or infection in the body -special cells react to each kind of pathogen with a defense targeted specifically at that pathogen-major organs/structures of the immune system include the white blood cells, mucus, and ciliaBrainpop: Immune System
61 Nervous System-receives information about what is happening both inside and outside your body-directs the way in which your body responds to information-helps maintain homeostasis
62 Nervous System -major organs/ structures of the nervous system include the brain, spinal cord, and nervesBrainpop: Nervous System
63 The Stroop Effect- Your Brain Can Get Confused! TRY IT!- The famous "Stroop Effect" is named after J. Ridley Stroop who discovered this strange phenomenon in the 1930s. Here is your job: name the colors of the following words. Do NOT read the words...rather, say the color of the words. For example, for the word BLUE, you should say "RED". Say the colors as fast as you can. It is not as easy as you might think!
64 Alzheimer’s DiseaseAlzheimer's disease attacks the brain; it is not a normal part of aging. People with AD have a gradual memory loss and difficulties with language and emotions.The progressive loss of intellectual abilities is termed dementia. As the disease advances, the person may need help in all aspects of life: bathing, eating, and using the restroom.Because of this round-the-clock care, families and friends of people with AD are greatly affected. The disease is irreversible and there is currently no cure.
