2. When a healthy person, male, aged 20-30 years old wants to
climb Mount Everest, there will be some changes in the
circulatory and respiratory system.
• It is stressed, but will adapt. The circulatory system cannot
work as efficiently, because there is less oxygen and CO2.
After being at a high altitude for a long time, the body will
adapt
• will produce more red blood cells so that it can pick up more
oxygen, since less oxygen is carried by each hemoglobin at
high altitudes.
• When respiration takes place, oxygen needs to be transported
to all the body and for the deoxygenated blood to be cleaned.
The heart cleans that blood as well as transport/delivers the
oxygen and the cleaned blood called oxygenated blood
3. At the peak of the mountain, which has the highest
altitude:
• Respiratory system = Faster, deeper breathing (a
higher tidal volume in the lungs) because of an
increased oxygen demand, and carbon dioxide
must be expelled.
• Circulatory system = Heart beats faster because
more oxygen is needed around the body (high
altitudes = low oxygen levels), and carbon dioxide
expelled.
4. At high altitude, a person could suffer from hypoxia. The early signs and symptoms of this disease
are:
Signs of Hypoxia
Poor coordination
Rapid breathing
Poor judgment
Cyanosis ( the skin turns blue in color)
Lassitude/ Lethargy
Symptoms of Hypoxia
Hot and cold flashes
Muscle and mental fatigue
Headache
Air Hunger
Nausea
Dizziness
Euphoria
Tingling
Visual Impairment
5. MALE VS FEMALE
Females are better climbers because:
they weigh less therefore gravity has less
of an effect than a 200 lb male. that and
they have wider hip cavities allowing for a
wider range of movement of the legs than
a male.
