Explanation: In your blood you have different kinds of cells. You have some cells that are called red blood cells that carry oxygen to your body and they can carry carbon dioxide back to your lungs so that's what your blood red cells are.

Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.

oksano4ka [1.4K]

Answer:

Your body will always try to keep you at the same temperature, for example, even when it's raining. Asthma is a good example of homeostasis gone wrong and the body acts out of proportion to a stimulus starting a process that leads to symptoms.
