Study Notes
Respiratory and Circulatory System Processes
- Iron ingested from diet and absorbed by active transport
- Transferrin protein transports iron in plasma to either liver for storage or bone marrow for hemoglobin formation
- Hemostasis steps: vasoconstriction, platelet plug formation, clot formation
- Primary functions of respiratory system: gas exchange, pH regulation, protection, vocalization
- Pleural sac importance: double-layered membrane around lungs, prevents friction, maintains lung inflation
- Alveolar sac cells: type 1 for respiration, type 2 secretes surfactant, alveolar macrophage for immunity
- Respiratory membrane components: alveolar type 1 cell, basement membrane, pulmonary capillary endothelium
- Pulmonary circulation pathway: right ventricle, pulmonary trunk, arteries, capillaries, venules, veins, left atrium
- Mucociliary escalator: traps and removes pathogens, involving mucus, saline layer, and cilia
- Dalton’s law: sum of partial pressures in a container equals total gas pressure
- Boyle’s law in respiratory system: volume changes inversely affect pressure
- Lung volumes and capacities definitions and calculations: TV, IRV, ERV, RV, IC, FRC, VC, TLC
- Pressure changes in lungs during quiet breathing: intrapleural and alveolar pressure fluctuations, volume changes
