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?

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.

• 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

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.

• 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.

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.

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

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.
