The partial pressure of oxygen (O2) determines how much oxygen can be delivered from the lungs to the blood. At higher altitudes the partial pressure of oxygen is lower and it is therefore harder to extract the oxygen from the air to bind with the hemoglobin. Because of the oxygen deficit as compared to sea level breathing rate increases.

∙ 13y agoThe primary stimulus to respiration is the level of C02 in the brain. As C02 rises the drive to increase the rate of breathing is increased. As that rate increases the levels of C02 within the blood decrease and the drive is depressed. This is called a feedback response loop. In addition very low levels of oxygen in the blood can also increase the drive to respiration but unless you are climbing a very high mountain it isn't normally relevant.

How the rate of respiration controlled by the animal organism?
Breathing is the mechanical procedure in which air reaches the lungs. The rate of respiration is controlled by a respiratory center in the brain stem that responds to changes in the hydrogen ions and carbon dioxide in the blood.
What are the 2 connections between respiration rate and pulse rate?
The respiration rate is your breathing rate and your pulse rate is your heart beat.
Is either photosynthesis of respiration controlled by enzymes?
respiration is but photosynthesis isn't.
What is respiration rate?
The respiration rate is the number of breaths taken in 1 minute.
What is the normal human respiration rate what are the factors affecting respiration rate in humans?
I
The rate of respiration is determined by what levels in the blood?
The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.
What effects the rate of respiration in plants?
oxygen effects the rate ofn respiration in plants
What is the rate of respiration determined by levels in blood?
The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.
What is the normal rate of respiration rate?
30
What is a pig's normal respiration rate?
A pig's normal respiration rate is between 20 and 40 breaths per minute. This respiration rate is normal for pigs that are still eating and growing.
How is the rate of respiration related to the amount of co2 in the blood?
Carbon bi oxide is powerful stimulant for the respiration. Increase in carbon bi oxide increase the rate of respiration. Decrease in carbon bi oxide decease the rate of respiration.
Why does respiration rate go up after exercise?
the respiration rate goes up because the energy required by the cell cannot be provide by the normal rate of respiration
