What is the function of the respiratory system?

Answers

Answer 1

Answer is A because your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.

Hope this helps!

Answer 2

Answer:

The lungs and respiratory system permit us to relax. They bring oxygen into our bodies (called inspiration, or inhaling) and send carbon dioxide out (called expiration, or exhalation). This trade of oxygen and carbon dioxide is called respiration.

In many areas of the world, wood is the easiest fuel to use for heating and cooking
If the human population continues to rise, how would this consumption most likely affect the Earth's systems?
A. The use of fossil fuels will decrease as more people start to use wood.
O B. It will affect more forest habitats as people need larger supplies of wood.
O C. The risk of climate change will decrease because people are not using oil.
D. Less carbon dioxide will be released into the atmosphere because wood does not contain carbon.

Answers

Answer:

B. It will affect more forest habitats as people need larger supplies of wood.

Explanation:

If wood is the easiest fuel for heating and cooking and people use it really common and if the human population grows, wood will run out easily. Wood is a limited supply as there isn't an infinite amount of trees in the world, trees normally take ten to twenty years to fully grow and there are billions of people in this world, but not billions of trees. Trees are also being cut down not only to use it as fuel to heat up things and cook, but also to have much more space for estates, malls and places.
