The tidal volume and the rate increased drastically from normal breathing. 10. What might cause a person to hyperventilate? Anxiety‚ fear‚ and even high altitudes with a decrease in oxygen would cause to body to breath faster and deeper to maintain homeostasis. Activity 2b: Hyperventilation – Run 2 1. What

Communication‚ Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal
