When climbing a mountain, a person's circulatory and respiratory systems adapt to increased physical demands through a stronger heart and increased blood flow to active muscles. At high altitudes, both systems are stressed by low oxygen levels. Symptoms of altitude sickness include headache, nausea, fatigue, and confusion. Treatment options are resting at the current altitude, slowly descending to lower elevations, or using supplemental oxygen. Physiological responses are generally the same between sexes for healthy individuals.

2. Describe the changes in his
circulatory and respiratory system
when…….?
i. is climbing the mountain (hint:
strenuous activity)
ii. when he reached the highest peak
(hint:altitude)
iii. if he were to suffer from
hypoxia/high altitude sickness.
What are his symptoms and what
are the possible treatment?

3. 1.
Describe the change in circulatory and respiratory
system when a a healthy person,male, aged 20-30
years old climbing the mountain (hint: strenuous
activity)
• The physiology of exercise is a broad concept
that addresses the central issue as to how the
body adapts itself to the demands of physical
activity.
• When the body is subjected to exercise, and its
increased physical demands, the cardiovascular
system is forced to work more quickly and more
efficiently to fulfill bodily needs. A number of
physiological changes occur over time to this
system through exercise.
• The cardiac muscle of the heart will grow
stronger over time, as the heart becomes
adapted to working harder during exercise.

4. • Physiological change experienced by the
cardiovascular system due to exercise is the
reduction of blood pressure.
• The circulatory system ,the heart rate increase
and blood flow increase to the exercising
muscles and lessens to the other parts of the
body.
• Your respiratory system does not change except
for the amount of air flow

5. 2. Describe the change in circulatory and respiratory
system when a a healthy person,male, aged 20-30 years
old reached the highest peak (hint:altitude)
• The cardiovascular changes at high altitude are
influenced by factors such as population
ancestry and sociocultural determinants, as well
as adaptation, nutrition, intercurrent
infection, exposure to pollutants and
toxins, socioeconomic status, and access to
medical care.
• Barometric pressure decreases as one rises in
altitude and moves toward the poles.
• Both circulatory and respiratory system are
stressed.

6. • The circulatory system can not work as
efficiently , because there is less oxygen and
carbon dioxide. Increased sympathetic activity
lead the increase in heart rate.
• The respiratory system will difficult to breath.
This is due to high oxygen demand. Oxygen at
that time stay at same concentration but the
atmospheric pressure decreased.

7. 3.
If he were to suffer from hypoxia/high altitude
sickness. What are his symptoms and what are the
possible treatment?
• Altitude illness refers to a group of syndromes
that result from hypoxia. Acute mountain
sickness (AMS) and high-altitude cerebral
edema (HACE) are manifestations of the brain
pathophysiology, while high-altitude pulmonary
edema (HAPE) is that of the lung.
What causes altitude sickness?
• Air is "thinner" at high altitudes. When you go
too high too fast, your body cannot get as much
oxygen as it needs. This causes the
headaches and other symptoms of altitude
sickness. As your body gets used to the
altitude, the symptoms go away.

8. What are the symptoms?

•
The symptoms of altitude sickness/hypoxia are :
A headache, which is usually throbbing. It gets
worse during the night and when you wake up.
Not feeling like eating.
Feeling sick to your stomach. You may vomit.
Feeling weak and lazy. In severe cases, you do
not have the energy to eat, dress yourself, or do
anything.
Waking up during the night and not sleeping
well.
Feeling dizzy.
Confused, not being able to walk
straight, feeling faint, and having blue or gray
lips or fingernails

How is it treated?
If he/she have mild symptoms, he/she may be able
to stay at that altitude and let their body get used to
it.
May also be able to use oxygen or a specially
designed pressure chamber to treat altitude
sickness.
Limit any walking or activity and drink plenty of
water.
can take an over-the-counter medicine, such as
acetaminophen (Tylenol), ibuprofen (Advil, Motrin)
or naproxen (Aleve).
Go to a lower altitude if the symptoms are
moderate to severe, they get worse, or medicine or
oxygen treatment does not help. Go down at
least 1500 ft (457 m). Go to a lower altitude as fast
as you can or get emergency help

12. BONUS!!!
Would it make any difference if the
climber is a female?
• No, for me both
sexes will face the
same. As long as
the individuals are
healthy and their
circulatory and
respiratory system
are well function.
