Cardiovascular and Respiratory Regulatory systems - Coggle Diagram
Cardiovascular and Respiratory Regulatory systems
Components
Cardiovascular centre (in brain stem)
Respiratory centre (in brain stem)
Sensory receptors (in aorta, carotid arteries, and vena cava)
Hormones (e.g., adrenaline)
Target cells with specific receptors
Effectors (heart, blood vessels, respiratory muscles)
Process:
Increased physical activity
Release of hormones into bloodstream
Hormones bind to receptors on target cells
Increase in heart rate
Increase in breathing rate and depth
Feedback Loop:
Sensory receptors monitor blood chemistry and pressure
Information sent to cardiovascular and respiratory centres
Ongoing adjustments to maintain homeostasis
Importance
Chemical messengers
: Hormones act as potent chemical regulators, produced in small quantities but exerting significant effects on metabolism throughout the body.
Targeted action
: Despite being distributed throughout the body via the bloodstream, hormones only affect specific target cells that have the appropriate receptors, allowing for precise control of physiological processes.
Long-lasting effects
: Hormonal responses can be long-lasting as the hormone continues to circulate in the blood, providing sustained regulation of physiological processes.
