Final answer:
When faced with a lion or a cutlass cut, the body undergoes several physiological responses. The autonomic nervous system becomes activated, leading to changes in heart rate, sweat glands, lungs, pupils, and blood flow to muscles.
Step-by-step explanation:
In response to the presence of a lion, the body undergoes several physiological responses. The autonomic nervous system, specifically the sympathetic division, becomes activated, leading to the release of adrenaline into the circulatory system. This causes several changes in the body, including an increase in heart rate, activation of sweat glands, dilation of bronchi in the lungs, dilation of pupils, and an increase in blood pressure and blood flow to skeletal muscles.
These responses prepare the body for the fight-or-flight response, enabling it to either confront or flee from the threat. Similar physiological responses would occur in a cutlass cut, as the body perceives it as a threat and activates the same autonomic responses.
