The control of ventilation is the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration.
Respiratory adaptation is the specific change that the respiratory system undergoes in response to the demands of physical exertion. Intense physical exertion, such as that involved in fitness training, places elevated demands on the respiratory system. Over time, this results in respiratory changes as the system adapts to these requirements. [1]
The number of respiratory cycles per minute is the breathing or respiratory rate, and is one of the four primary vital signs of life. [5] Under normal conditions the breathing depth and rate is automatically, and unconsciously, controlled by several homeostatic mechanisms which keep the partial pressures of carbon dioxide and oxygen in the ...
The first-line physiologic response to this demand is an increase in heart rate, breathing rate, and depth of breathing. Oxygen consumption (VO 2 ) during exercise is best described by the Fick Equation : VO 2 =Q x (a-vO 2 diff), which states that the amount of oxygen consumed is equal to cardiac output (Q) multiplied by the difference between ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
v. t. e. Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels.
Cardiorespiratory fitness (CRF) refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. Scientists and researchers use CRF to assess the functional capacity of the respiratory and cardiovascular systems. These functions include ventilation, perfusion, gas exchange ...
Ventilation refers to the in-and-out movement of air of the lungs and perfusion is the circulation of blood in the pulmonary capillaries. [1] In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement that brings air into the lungs where the process ...
