STRUCTURE AND FUNCTION OF THE CV AND LYMPHATIC SYSTEMS 1. Understand the basics of cardiac muscle contraction > Cross-bridge cycling -Attachment of actin to myosin at the cross bridge -Myosin head molecule undergoes a position change -Causes thin filaments to slide past thick filaments (contraction) Calcium -Is stored in the tubule system and the sarcoplasmic reticulum -Enters the myocardial cell from the interstitial fluid after electrical excitation, which increases membrane permea...

Structures of pulmonary system − NOT ON STUDY GUIDE • Lobes (3 on right, 2 on left) - segments − lobules • Blood vessels serve the pulmonary system • Chest wall/thoracic cage • Diaphragm: involved in ventilation − dome shaped muscle that separates the thoracic and abdominal cavities • Mediastinum: space between lungs containing heart, great vessels, and esophagus • Conducting airways o Upper airways: warms and humifies air ▪ Nasopharynx and oropharynx o Larynx: conne...
