Body systems revision

Year 10 sport science

respiratory system
Respiratory system
  • Allows air to travel to our lungs from body
  • FUNCTION
  • Supplies oxygen to all parts of the body
  • Consists of:
  • Pharynx
  • Larynx
  • Trachea
  • Lungs
  • Bronchus
  • Bronchiole
  • Alveoli
  • Diaphragm
respiratory system2
Respiratory system
  • Inspiration and Expiration
  • Inspiration
  • Contraction of intercostal muscles
  • Diaphragm contracts downwards
  • Increase size of thoracic cavity and lung space
  • Air pressure in lungs decreased
  • Expiration
  • Intercostals and diaphragm relax
  • Space inside lungs decreases
  • Air pressure in lungs increased
respiratory system3
Respiratory system
  • Tidal Volume - amount of air inhaled and exhaled per breath (600mL male)
  • Minute ventilation – volume of air moved into and out of respiratory tract each minute
  • Minute ventilation (VE) = respiratory rate × tidal volume
  • At rest, minute ventilation = 12 × 0.5 L = 6.0 L/min
skeletal system
Skeletal system
  • Bone structure of body
  • FUNCTION
  • Movement of body
  • Support
  • Two sections:
  • Axial skeleton- bones of skull, spine, thorax
  • Appendicular skeleton- bones of upper and lower extremities
skeletal system1
Skeletal system
  • TYPES OF BONES
  • Long bones (eg. Femur)
  • Short bones (eg. Tarsals)
  • Flat bones (eg. Sternum)
  • Irregular bones (eg. Vertebrae)
  • Sesamoid bones (eg. Patella)
  • Sutural bones (eg. Skull)
skeletal system2
Skeletal system
  • TYPES OF JOINTS
  • Gliding Joint
  • Ball and Socket Joint
  • Pivot Joint
  • Hinge Joint
  • Saddle Joint
  • Condyloid Joint
muscular system
Muscular system
  • FUNCTION
  • Allow movement to occur
  • TYPES OF MUSCLES
  • Smooth- involuntary (eg. Stomach)
  • Skeletal- voluntary (eg. Quadricep)
  • Cardiac- involuntary (eg. Heart)
muscular system1
Muscular system
  • Types of movement
  • Flexion- shortening of muscle
  • Extension- lengthening of muscle
  • Abduction- movement away from body
  • Adduction- movement towards body
muscular system2
Muscular system
  • Supination- outward action of hand
  • Pronation- inward action of hand
  • Eversion- outward action of foot
  • Inversion- inward action of foot
  • Dorsi flexion- upward action of foot
  • Plantar flexion- downward action of foot
circulatory system
Circulatory system
  • Transportation of blood throughout the body
  • Removal of waste products
  • Consists of:
  • Heart - (ventricles, atrium, aorta, vena cava, pulmonary artery, pulmonary vein)
  • Blood - (RBC, WBC, platelets, plasma)
  • Blood vessels - (arteries, arterioles, capillaries, venules, veins)
