  1. Title your page:Body Systems Notes Learning Goal: Iwill identify the main functions of the systems of the human organism.

  2. Body System Notes Set up your notebook as shown below for ALL 10 body systems. 1. Circulatory (Cardiovascular) System 3. Muscular System Function: Only write ONE part at a time. For example, write the whole Circulatory System’s Function before you write the word ORGANS in order to ensure you have enough space. Organs: 2. Respiratory System 4. Skeletal System • For EACH system, you will need to have: • Function • Organs • Picture- Fold this in ½ to create flaps

  3. This is what your notebook will look like when finished. Box and Highlight the systems’ name Cut the picture as small as you can. Fold it in ½ to create flaps. Tape it at the top of the picture.

  4. 5. Digestive System 7. Excretory (Urinary) System 6. Endocrine System 8. Integumentary System

  5. 9. Nervous System 10. Reproductive System

  6. Circulate = to move Cardio = heart The Circulatory (Cardiovascular) System

  7. FUNCTION:Delivery system that moves oxygen and nutrientsTOthe body's cells, and carries AWAY carbon dioxide and waste materials.

  8. Organs of the Circulatory System • Heart • Blood • Blood Vessels: • Arteries: carry blood AWAY from the heart • Veins: carry blood INTO the heart • Capillaries: connect arteries and veins

  9. Read Only Arteries • Carry blood away from the heart • Have strong, muscular walls • The inner layer is very smooth so that the blood can flow easily http://hes.ucf.k12.pa.us/gclaypo/circdia.html

  10. Read Only Veins • Carry blood to the heart • Transport waste-rich/ oxygen-poor blood back to the lungs and heart • Valves inside the veins make blood move in one direction http://hes.ucf.k12.pa.us/gclaypo/circdia.html

  11. Read Only Capillaries • Only one cell thick (very small size) • Connect arteries & veins • Food and oxygen released to the body cells • Carbon dioxide and other waste products returned to the bloodstream http://sln.fi.edu/biosci/systems/circulation.html

  12. Read Only The Circulatory System acts as a delivery system to carry and deliver oxygen and nutrients to the body’s cells and in return, picks up carbon dioxide and wastes to be removed from the body.

  13. Circulatory System works closely with... • Respiratory System • Digestive System • Excretory System • Nervous System

  14. The Respiratory System Respire = to breathe

  15. Function of the respiratory system • Gas exchange: delivering oxygen to the body (inhale) and removing carbon dioxide from the body (exhale). • Gases are carried within the blood.

  16. Read Only • The diaphragm is the muscle under the lungs. • It contracts and relaxes to moves gases (oxygen and carbon dioxide) in and out of the lungs. http://mhln.com

  17. Major organs include: nose & mouth, trachea, lungs, diaphragm, alveoli http://www.bbc.co.uk

  18. Respiratory system works closely with... • Circulatory System • Excretory System • Nervous System

  19. Muscular System

  20. Muscular System • Function: Muscles enable the body to MOVE. They also help the body maintain posture. • Bones and joints have no power to move on their own. They are connected to muscles to provide movement. • There are more than 600 muscles in the body • 35–40% of body mass ismuscle. Read Only

  21. Read Only • Skeletal muscle movements are results of pairs of muscles working together. • One musclecontractswhile the other musclerelaxes. • Muscles alwayspull; theynever push.

  22. Write this information below function. • Two Groups of Muscles • Voluntary—muscles you can control. • Ex: Arms, legs, hands, face 2. Involuntary—muscles you can’t control; move automatically • Ex: Cardiac (heart) muscles, stomach, intestines In = not

  23. Organs: • Muscles: • Skeletal muscles • Smooth muscles • Cardiac muscles

  24. Read Only • Three Types of MuscleTissue 1. Skeletal Muscle • Attached to the bones by tendons • Tendons—thick bands that pull on the bone as the muscle contracts • Voluntary • Contract quickly, tire easily • Most numerous in body • Looks striped (striated)

  25. Read Only • Three Types of MuscleTissue (cont.) 2. Smooth Muscle • Involuntary • Found in: walls of stomach, intestine, uterus, etc. • Contracts and relaxes slowly • No striations

  26. Read Only • Three Types of MuscleTissue (cont.) 3. Cardiac Muscle • Only found in heart • Involuntary • Has striations • Contracts 70 times per minute (heartbeat)

  27. Muscular System works closely with... • Skeletal System • Digestive System

  28. Skeletal System

  29. 3 Main Functions of Skeletal System • Bones are the framework for the body providing its shape • Provides protection to internal organs (ribs, skull) • Blood Cell production

  30. Read Only ALL Functions of Skeletal System • Framework gives shape & support to the body. • Bones (ribs) protect the internal organs. • Major muscles of the body are attached to the bones. • Blood cells are created in red marrow of some bones. • Skeleton is a place where major quantities of calcium and phosphorus compounds are stored. • Each bone in your body is a livingorgan, made of different tissues. Cells in bones take in foodand use energy.

  31. Read Only • Theadult skeleton has 206 bones (baby has 270). As the baby grows, bones fuse (join) together resulting in a decreased total amount of bones.

  32. Organs of the Skeletal System • Bones • Joints (connect BONE to BONE by ligaments) • Tendons (connect BONE to MUSCLE)

  33. Read Only Joints • Any place where two or more bones meet (BONE to BONE) • Ligaments: tough bands of tissue that hold bones together at the joints

  34. Read Only Tendons • Flexible connective tissue that connects MUSCLE to BONE

  35. Skeletal System works closely with... • Muscular System • Nervous System

  36. Digestive System

  37. Main function of the Digestive System • Break down food into smaller pieces to convert food into essential nutrients that are absorbed into the body and moves the unused waste material out of the body.

  38. Read Only Functions of the Digestive System • Ingestion = Food enters the mouth.

  39. Read Only Functions of the Digestive System • Ingestion = Food enters the mouth. • Digestion = Process that breaks food down into small molecules • Mechanicaldigestion = Food is chewed and churned. • Chemical digestion = Breaks down large food molecules into smaller molecules to be absorbed by cells

  40. Read Only Functions of the Digestive System • Ingestion = Food enters the mouth. • Digestion = Process that breaks food down into small molecules • Absorption = Small molecules of food are taken into the body cells.

  41. Read Only Functions of the Digestive System • Ingestion = Food enters the mouth. • Digestion = Process that breaks food down into small molecules • Absorption = Small molecules of food are taken into the body cells. • Elimination = Wastes made of unabsorbed food molecules pass out of the body. Large Intestine

  42. Main organs of the Digestive System • Mouth • Esophagus • Stomach • Small and large intestines • Rectum • Anus

  43. Digestive System works closely with... • Circulatory System

  44. Endocrine System

  45. Function of the Endocrine System The endocrine system is composed of glands that release hormones(chemical messengers) into the bloodstream to control body functions such as growth, reproduction, and metabolism.

  46. Organs involved in the Endocrine System • Glands: • Pituitary • Thyroid • Adrenal (kidney) • Hormones

  47. Read Only Pituitary Pituitary The pituitary gland produces a growth hormone which controls growth and homeostasis.

  48. Read Only Parathyroid Parathyroid The parathyroid gland produces parathormone which controls calcium levels in the body.

  49. Read Only Adrenals Adrenals Adrenals The adrenal glands produce adrenaline in response to physical and emotional stress. Fight or Flight

  50. Read Only Thyroid Thyroid The thyroid gland produces thyroxin to regulate metabolism.
