 ACCESSORY Sternocleidomastoid Pectoral and brachialis muscles  HOMEOSTASIS The formula is always: 1. Receptors (SPIES) 2. Control Centre (DON) 3. Effectors (HITMEN) 1. CHEMORECEPTORS (Spies hidden in Medulla Oblongata-Keep eye out for C02 in CSF)/CHEMORECEPTORS (Spies in arteries as well, but keep eye out for partial pressure of C02 & 02)-They send the message through sensory neurones (cos they have fast wifi) 2. Control Centre (DON is Medulla Oblongata) 3. Effectors: Don sends message through PHRENIC NERVE ordering DIAPHRAGM to contract INHALATION related EXHALATION related OTHER ---------------------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- **Inspiratory reserve volume (IRV**): After you breath in, the most you can breath in further **Expiratory Reserve Volume (ERV)**: After breathing out, the most you can breath out further **Vital Capacity (VC):** The most amount of gas that can be exchanged in 1 single breath. TV+IRV+ERV **Inspiratory Capacity (IC):** After you breathed out, the most you can breath in. Tidal volume (TV)+IRV **Residual Volume (RV):** after you breathed out fully (max), the volume of gas left in your lungs **Total Lung capacity (TLC):** The most amount of gas your lungs and airways can hold. TLC = VC + RV = TV + IRV + ERV + RV **Tidal Volume (TV):** amount of gas exchanged in each breath **Functional Residual Capacity (FRC):** Volume of gas left in lungs after breathing out. FRC = RV + ERV RESISTANCE: =========== In my words: resistance is when there isn't enough space in a cavity (like its narrowed). In the lungs, this could be to do with mucous or disease and in blood vessels, this could be from plaque from smoking. Either way-there's some gunjee stuff which is disrupting normal flow. Watch video Then: Apply the following conditions to understand how resistance lowers flow of gas. PPT - Pathology of chronic obstructive airway diseases PowerPoint \...
