Presentation Transcript

  1. Human Body System

  2. Ten Body systems • Nervous • Skeletal • Muscular • Circulatory • Respritory • Digestive • Endocrine • Reproductive • Immune • Integumentary

  3. Digestive system • function of the digestive system is to help convert foods into simpler molecules that can be absorbed and used by the cells of the body

  4. Digestive System Parts • Pharynx • Esophagus • Mouth • Salivary glands • Stomach • Pancreas • Large/small intestines • Liver • Gallbladder • rectum

  5. Digestive

  6. Two way tube Mouth to anus

  7. Excretory System • The kidneys play an important role in maintaining homeostasis. They remove waste products from the blood; maintain blood pH; and regulate the water content of the blood and, therefore, blood volume.

  8. Excretory • Kidneys • Bladder • Adrenal gland

  9. Excretory System

  10. Kidneys

  11. Endocrine SYStem • The endocrine system is made up of glands that release their products into the bloodstream. These products deliver messages throughout the body.

  12. Endocrine System • Hypothalmus • Pituitary • Parathyroid • Thymus • Adrenal Glands • Pineal • Thyroid • Pancreas • Ovary • testis

  13. Endocrine System

  14. Coelom

  15. Reproductive System • Testes • Vas deferens • Uretha • Penis • Ovaries • Fallopian tubes • Uterus • Vagina

  16. Reproductive System • The main function of the female reproductive system is to produce ova. In addition, the female reproductive system prepares the female's body to nourish a developing embryo. • The main function of the male reproductive system is to produce and deliver sperm.

  17. Reproductive System Male Female

  18. SexualInternal Fertilization

  19. Immune System • The function of the immune system is to fight infection through the production of cells that inactivate foreign substances or cells.

  20. Immune System • Skin (first line of defense) • Mucus • White blood cells • Antibodies

  21. Immune System

  22. STOP

  23. Nervous System • The nervous system controls and coordinates functions throughout the body and responds to internal and external stimuli.

  24. Nervous System • Brain • Spinal cord • nerves

  25. Nervous System

  26. Cephalizationcentral nervous system with cerebral cortex

  27. Skeletal/MusculaR • The skeleton supports the body, protects internal organs, provides for movement, stores mineral reserves, and provides a site for blood cell formation. • There are three different types of muscle tissue: skeletal, smooth, and cardiac. Each type of muscle is specialized for a specific function in the body.

  28. Skeletal/Muscular • Skeletal • bones • Muscular • muscles

  29. Skeletal/Muscular

  30. Endoskeleton

  31. INtegumentary • The integumentary system serves as a barrier against infection and injury, helps to regulate body temperature, removes waste products from the body, and provides protection against ultraviolet radiation from the sun.

  32. INtegumentary • Skin • Hair • Nails

  33. INtegumentary

  34. Body Symmetrybilateral

  35. REspiratory • The basic function performed by the human respiratory system is remarkably simple—to bring about the exchange of oxygen and carbon dioxide between the blood, the air, and tissues.

  36. REspiratory • Nose • Pharynx • Larynx • Trachea • Bronchi • Lungs

  37. REspiratory

  38. Lungs

  39. Circulatory • The human circulatory system main jobs are to move blood, hormones, oxygen and other substances around the body.

  40. Circulatory • Heart • Blood vessels • Blood

  41. Circulatory

  42. Heart

  43. Closed SystemHeart with four valves

  44. THE end
