(5)
Study the same and answer the questions.
00 Name the system
(ii) Label 1-4
(ili) Name the two muscles that help in breathing
(iv) Write the chemical equation of respiration
(v) Why does a person feel breathless at higher altitude?​

Answer 1

Answer:

iii)The muscles of respiration (Respiratory muscle) are those skeletal muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing.

iv) The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).

v)In order for your lungs to breathe air in without duress, the pressure has to be higher outside your body. But at high altitudes, the outside air pressure is lower than it is inside your lungs, making it more difficult to pull in the thinner air and for your veins to pump oxygen throughout the body

Answer 2

Answer:

where is the figure dude

Explanation:

I can answer without figure

3rd) The diaphragm, the rib cage muscles and the abdominal muscles.

4th) The word equation for respiration is: Glucose + Oxygen = Carbon Dioxide and Water The chemical equation is C6H1206 + O2 = CO2 + H20 Respiration is used by all living humans and animals, to make energy for movement, heat and to keep vital organs running, without it we'd be dead.

5th) In order for your lungs to breathe air in without duress, the pressure has to be higher outside your body. But at high altitudes, the outside air pressure is lower than it is inside your lungs, making it more difficult to pull in the thinner air and for your veins to pump oxygen throughout the body.
