Reflex Action Stimulus Receptor Effects Increased body Lower leg kicks forwards due to sudden Pain receptors Salivation temperature contraction of front thigh muscles. Increased frequency and force of cardiac muscle contractions, so blood pressure Pain Olfactory and taste Pupil reflex raised and more blood carried to lungs for CO2 removal. Increased sweat release to cool body surface Light intensity Thermoreceptors Accommodation down. Raised blood HCO3- Increased frequency and depth of breathing Chemoreceptors Flexion reflex level to remove extra CO2 Decreased body Limb muscles flex, drawing limb away from Rods and cones Stretch reflex temperature pain, (pin, hotplate). Skeletal muscles have continual spasms to Stretching of muscles Thermoreceptors Knee jerk generate metabolic heat.
