Anatomy and Physiology - Respiratory System Flashcards
Baroreceptors
Sensors detecting changes in blood pressure
Breathing frequency
The number of breaths per minute
Chemical regulation
The control of physiological processes via the chemoreceptors
Excess post-exercise oxygen consumption
The increased volume of oxygen consumed following exercise
Expiration
The process of breathing out
Expiratory reserve volume
The extra air that can be exhaled after normal exhalation
Inspiration
The process of breathing in
Inspiratory reserve volume
The extra air that can be inhaled after normal inhalation
Medulla oblongata
An extension of the spinal cord found in the skull that contains control centres for the heart and lungs
Minute ventilation
The volume of air inspired or exhaled per minute
Neural control
The control of physiological processes via the sympathetic and parasympathetic nervous systems
Oxyhaemoglobin
A combination of oxygen and haemoglobin
Parasympathetic nervous system
One half of the automatic nervous system that stimulates body systems to rest or relax
Proprioceptors
Sensors that detect changes in body position through changes in muscle length, tension and joint angles
Residual volume
Amount of air left in the lungs prior to forced exhalation
