Human body

  1. 1. The Human Body • Chapters 34-39
  2. 2. Levels of OrganizationAtom Molecule Cell
  3. 3. Organ Organ Systems
  4. 4. Organism
  5. 5. Protection, Support, Locomotion• The Integumentary System – Skin, hair, nails – Epidermis, dermis, sub cutaneous – Proteins for protection – Maintains homeostasis – sweating, chills
  6. 6. The Skeletal System• Joints – where bones meet – Ball and socket – Pivot – Hinge
  7. 7. The Skeletal System• Functions: – Protection of internal organs – Production of blood cells – Muscle attachment
  8. 8. The Muscular System• Smooth muscle – Involuntary – can’t control – Stomach lining, intestines• Skeletal muscle – Voluntary - control – Biceps, triceps, hamstrings• Cardiac muscle – Involuntary – Heart muscle
  9. 9. Digestion and Regulation• The Digestive System – Function – break down and absorb nutrients – Organs • Mouth – digestive enzymes for carbs • Esophagus – tube to stomach • Stomach – HCl and digestive enzymes • Small Intestines – Absorption, high surface area • Large Intestines - Storage – Accessory Organs • Liver – detoxification, produces bile • Gall bladder – stores bile • Appendix – vestigial structure
  10. 10. The Endocrine System• Functions – Chemical messages in the body – Works with nervous system to control body• Hormones• Works by negative feedback• Glands
  11. 11. The Paomnnehal Pweor Of The Hmuan Mnid. Aoccdrnig to a rscheearch as Cmabrigde Uinervtisy,it deosnt mttaer in waht oredr the ltteers in a wrod are,the olny iprmoatnt tihng is taht the frist and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
  12. 12. The Nervous System• Neurons - Nerve cells• Brain• Spinal Cord• The Senses – Vision – Hearing – Smell – Taste – Touch
  13. 13. Respiration, Circulation and Breathing• Respiratory System – Trachea – cartilage covering – Bronchi – right and left – Lungs – Alveoli – location of gas exchange – Diaphragm – muscle for breathing
  14. 14. The Circulatory System• Blood – RBC’s – hemoglobin carries oxygen, anucleate – WBC’s – protect from disease – Platelets – clot blood, scab – Plasma – liquid part of blood
  15. 15. The Circulatory System• Blood Vessels – Arteries – carry blood away from heart – Veins – carry blood to the heart – Capillaries – connect arteries to veins, diffusion
  16. 16. The Circulatory System• Heart – Heart is a muscle, middle and a little to the left – Protected by ribs, sternum, and vertebrate – Atrium – right and left, small upper chambers – Ventricles – right and left, large, lower
  17. 17. The Urinary System• Kidneys – Filter blood and remove waste – Maintain homeostasis• Ureters – carry waste from kidney to bladder• Bladder – waste (urine) storage• Urethra – takes urine out of body
  18. 18. The Immune System• Body’s internal protection• White blood cells• Antibodies
