A group of organs that work together L.1:Huma to performing major function n body systems Miss. Fatma Mohamed The body is made up of: Group of similar cells cells tissue The basic organs unit Systems Composed of different kinds of tissue that work together  The human body systems Digestive sys. Nervous sys. Respiratory sys. Circulatory sys. Excretory sys. Endocrine sys. Digests & Control the Breath in - Distribute the Remove Control absorbs food body oxygen and digested food & wastes growth and responses out carbon oxygen. energy dioxide process 3  The human body systems skeletal sys. integumentary sys. muscular sys. immune sys. reproductive sys. Support body and Guard against allow Fights infections Produce and allow movement infection movement deliver six cells 4  The human body systems are working together Epithelial tissue gives the Nerve cells help kidney filter kidney structure and protect it blood Muscle cells push urine to bladder Connective tissue protect the kidney  The human body systems 1- Control systems: Brain A. Nervous system: Spinal cord Function: E.X. Nervous Send tissue connect information to the kidney nerves through nerve help to control cells to control its function your actions. Nerve tissue carry electrical signals from and to the brain 6 The human body systems 1- Control systems: B. Endocrine system: It is: A collection of glands that produce important chemicals that affect. - Your mood. - Body temperature - Energy level - digestion 7  The human body systems Work to shape, move and 2- structural systems: protect your body A. Skeletal system: Function: Connective tissue bones - Support and cushion bones protect your and attach them Connective body. to muscles. tissue - Make blood cells. - Store minerals 8  The human body systems 2- structural systems: B. muscular system: Function: Includes: - Muscle tissue 650 muscles that contract to control your allow movement. movement. - Keep your blood and food moving. 9  The human body systems 2- structural systems: C. integumentary system: nail Function: Function: Skin is: - Protect your The larges organ - Regulate body body from temperature. that has epithelial hair outside Guard against tissue that - damage. infection and skin protect your inside from injuries. Oil and damage. sweat glands 10  The human body systems 3- Oxygen and transport systems: A. Respiratory system: Nose Function: pharynx Breathe in Oxygen and breathe out carbon trachea dioxide Bronchi Lung 11  The human body systems 3- Oxygen and transport systems: B. Circulatory system: Heart Heart: Function: Blood - Transport Pumps blood in vessels blood vessels oxygen, (such as Veins: carbon veins) Bring the blood dioxide, back to the heart wastes and and lungs. nutrients. 12  The human body systems 4- Food and waste processing systems: A. digestive system: mouth Esophagus Esophagus: Squeeze the food down - Undigested stomach Liver into stomach. food pass out stomach: Break down the food by from the body pancreas acids. as wastes. Liver & pancreas: Small intestine Produce chemicals break down the food in Large intestine small intestine then it goes to blood. rectum 13  The human body systems 4- Food and waste processing systems: A. Excretory system: kidney function: Gets rid of waste lungs: product and toxic Release carbon dioxide substance in your body. Liver : Kidney: Break down toxic Has nephron that filter substances so the the blood producing kidney can release it urine. bladder Sweat glands: In skin produce sweat 14  The Defense systems The immune system: Lymph nodes & White blood cells: lymph vessels: Produced inside bones. Trap bacteria and Attack and destroy any viruses. cause of disease. Swollen glands: Lymph nodes that grow larger to fight infection 15  The reproductive system Producing sperm in males and eggs in females for nurturing the fetus (new baby) A. male Female: organs: organs : 1- Testes 1- ovaries. sperm (testicles). 2- uterus. 2- Peins 3- vagina Egg 16  L.2: systems interaction work together Miss. Fatma Mohamed The human body systems are working together Muscular Skeletal system system nervous system Help in moving The human body systems are working together Endocrine system nervous (chemical system signals) (electrical signals) Control functions The human body systems are working together wastes oxygen chemical from cells from from to respiratory Endocrine excretory system system system Food from digestive system Transporting materials by blood Carbon dioxide waste from cells to in the circulatory respiratory system system Nervous system Respond for any stimuli stimulus: respond: signal from action or environment behavior as a such as : result of Smell. stimulus Color. Sound. 21 Endocrine systems & Hormone control Gland: organ that produces and release chemicals through tubes called ducts or to bloodstream directly Hormones: chemicals produced by the glands in endocrine system Carried by blood Work with Excretory & circulatory to regulate the amount of water Work with Digestive /circulatory regulate amount of sugar Work with Reproductive system during puberty
