When a person reaches high altitudes, the immediate response of the circulatory system is an increase in heart rate and cardiac output. This is triggered by lower oxygen levels in the atmosphere, prompting the body to pump more blood to deliver adequate oxygen to tissues. Additionally, the body may also begin to produce more red blood cells over time to enhance oxygen transport.

Heat Stroke- is a response to heat characterized by extremely high body temperature and disturbance of the sweating mechanism. it is a immediate life threatening emergency.
Advantage of open circulatory system: * requires less engergy for distribution * it need less need of oxygen * blood pressure remain low Disadvantages for open circulatory system: * not very effective, because fluid is pumbed under low pressure, so it corculates more slowly than in closed circulatory system Advantage of closed circulatory system * Operates much higher blood pressure * blood pumped under high pressure so it reaches destination quickly * immune response are much Stronger, helping body fight infection Disadvantage: * stronger heart is required, more energy to maintain * is complex but more powerful
when the temperature reaches the dew point.
To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
No, during a reflex arc, the nerve impulse does not reach the brain before the reflex action occurs. Instead, the impulse travels from the sensory receptor through the spinal cord to the motor neurons, which directly trigger a response. This allows for a quick reaction to stimuli, bypassing the brain for immediate response. The brain may become aware of the stimulus and the reflex action afterward.
Stratosphere Commercial airliners typically cruise at altitudes of 9-12 km (30,000-39,000 ft) in temperate latitudes (in the lower reaches of the stratosphere)
Differences in air temperatures at different altitudes are primarily caused by the way the atmosphere absorbs and retains heat from the sun. As you increase in altitude, the air pressure decreases, causing the air to expand and cool. This results in lower temperatures at higher altitudes compared to lower altitudes.
Proctor tells her that he will cut his hands off before he reaches for her again.
At higher altitudes, the boiling point of water is lower due to decreased atmospheric pressure. This means that water reaches a lower temperature when boiled, resulting in a less hot cup of tea than at sea level.
Water vapor condenses when it reaches higher altitudes in the atmosphere due to a decrease in temperature and pressure. As air rises, it expands and cools, causing the water vapor to lose energy and change from a gas to a liquid state, forming clouds. This process is known as condensation, and it occurs when the air reaches its dew point, where it can no longer hold all the moisture in vapor form.
