1.2 - Body Systems

• structural system provide the basic 'framework' and transport system for the body
• coordinating systems control mechanisms of the body
• visceral systems are all the basic functional systems that do general duties for the body
• do bones move?

  no
• how do bones move?

  muscles
• skeletal system - the supporting frame upon which the body is built (bones and joints)
• muscular system - the mechanism that connects to the bones for locomotion
• integument - the body covering
• cardiovascular system - transport the blood into the whole body
• structural systems:

  Skeletal,

  Muscular,

  Integumentary,

  Cardiovascular
• nervous system - carries info from and into the brain of the body. also, controls and monitors the internal and external environment of body
• digestive system - taking food and breaking them down to utilised by the body
• respiratory system - responsible for taking oxygen and removing carbon dioxide
• striated muscle is the one that is attached in skeleton for movement
• smooth muscle is found in walls of hollow organs such as stomach, intestines, uterus, bladder, arteries, veins.
• examples of smooth muscle: walls of blood vessels, digestive tract, respiratory tract, bladder, uterus
• smooth muscles are found in the regions of the body that are under involuntary control
• cardiac muscle is only found on?

  heart
• cardiac muscle forms ____?

  myocardium
• cardiac muscle is only found in the heart and forms the myocardium
• cardiac muscle is responsible for the rhythmic and automatic contraction of heart throughout the life
• what is the other term for the voluntary muscles?

  somatic muscle
• what is called to the involuntary muscle according to doc philip's ppt?

  visceral muscle
• what is the other term for serous membrane that lines all the body cavities?

  endothelium
• three body cavities: thoracic, abdominal, pelvic cavity
• parietal is the serous membrane that lines the boundary or sides of the cavity
• visceral is the serous membrane that covers all the organs within the cavity
• abdominal and pelvic cavities are not separated by a physical barrier
• cranial boundary of thoracic?

  thoracic vertebrae and hypaxial muscle
• ventral boundary of thoracic cavity?

  sternum
• lateral boundary of thoracic cavity?

  ribs and intercostal muscle
• cranial boundary of abdominal cavity?

  diaphragm
• caudal boundary of abdominal cavity?

  pelvic inlet
• dorsal boundary of abdominal cavity?

  lumbar vertebrae and hypaxial muscles
• ventral boundary of abdominal cavity?

  muscles of ventral abdominal walls
• lateral boundary of abdominal cavity?

  muscles of lateral abdominal walls
• cranial boundary of pelvic cavity?

  pelvic inlet
• caudal boundary of pelvic cavity?

  pelvic outlet
