Cards (14)

  • Respiratory system
    Also known as the human breathing system, responsible for taking in oxygen and expelling carbon dioxide
  • Parts of the respiratory system
    • Nose and mouth
    • Nasal cavity or nasal passageways
    • Pharynx
    • Larynx
    • Trachea
    • Lungs
    • Bronchi
    • Bronchioles
    • Alveoli
  • Inhalation
    1. Oxygen enters the body
    2. Ribs move out, chest space increases
    3. Diaphragm muscle contracts, moves down
  • Exhalation
    1. Carbon dioxide exits the body
    2. Ribs move in, chest space decreases
    3. Diaphragm muscle relaxes, moves up
  • Circulatory system
    Also known as the cardiovascular system, the life support structure that nourishes cells and delivers materials in the body
  • Major parts of the circulatory system
    • Heart
    • Blood vessels (arteries, veins, capillaries)
    • Blood
  • The heart is a hollow muscle as big as your fist
  • Parts of the heart
    • Right atrium
    • Left atrium
    • Right ventricle
    • Left ventricle
    • Tricuspid valve
    • Bicuspid valve
    • Pulmonary valve
    • Aortic valve
    • Superior vena cava
    • Inferior vena cava
    • Pulmonary artery
    • Pulmonary vein
    • Aorta
  • Circulatory system function
    Air enters lungs, goes to left side of heart, pumped through body, oxygen processed by cells, carbon dioxide returned to right side of heart, expelled through lungs
  • Types of circulation
    • Pulmonary circulation
    • Coronary circulation
    • Systemic circulation
  • The circulatory system functions with other body systems to deliver different materials and transport waste away from the body
  • The bronchi are two tubes that branch off from the trachea into the lungs.
  • The trachea is the windpipe, which connects to the larynx.
  • Bronchial tree refers to the network of airways within the lungs.
