Nervous System
The two nervous systems
What is central nervous system and peripheral nervous system
The difference of pulmonary ventilation and diffusion
What is ventilation is movement of air in and out of lungs, while diffusion is movement of gases between air and lungs
2 circuits of heart
What is pulmonary and systemic circuit
Where are chemoreceptors locates
What is the medulla
The ability to maintain internal equilibrium of the body
What is homeostasis
Site of exchange of O2 and CO2
What is alveoli
Respiratory pump
What is change in intrathoracic and intraabdominal pressure during expiration and inspiration
Tidal volume
What is amount of air moved per breath
A synapse is
What is the point of communication between two cells
Pressure change during ventilation
What is increase in volume of intrathoracic cavity, diaphragm flattens, ribs elevate
Name the valves of the heart
What is the tricuspid, bicuspid, and semilunar pulmoary valves (L) & (R)
What is P1-P2/resistance
The two parts of the peripheral nervous system and what do they do
What is the sympathetic nervous system - fight or flight and the parasympathetic nervous system - rest and digest
Functions of the resp. system
What is conducts air in and out of the body, humidifiers air, warms air, and filters air
Fick Equation
What is oxygen delivery=Blood Flowxa-vO2 diff
Partial pressure
What is portion of pressure due to gas in a mixture of gases
The types of motor units
What is type s (slow) type FR) fast,fatigue resistant and type FF (fast, fatigable)
The movement of air in the body
What is the nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronciholes, alveoli
Name 4 parts that assist in circulation in the heart and their function
What is arteries:large vessels carrying blood away from the heart. Capillaries:small vessels that assist in gas exchange, venules: small veins carrying blood to heart, veins:vessels that carry blood towards heart
Oxygen diffusion
What is differences between PO2 in alveoli and blood between blood and tissue provide driving force for diffusion of oxygen
