Answer:
It will remove the major site of red blood cell (RBC) destruction.
Explanation:
For clients with autoimmune hemolytic anemia, if corticosteroids do not cause a lessening or recovery of the disease conditions, a splenectomy (i.e., getting rid of the spleen) may be executed since it takes away the main site of Red Blood Cells (RBC) destruction.
After splenectomy, the hemoglobin concentration almost always raises, reticulocytes reduces, bilirubin levels return to usual, and RBCs have a moderately normal life span.

Answer:
The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.
Explanation:
Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.
The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).
This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.
- The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
- CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.
Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.

Auroras occur in the <u>"thermosphere".</u>
The thermosphere lies between the exosphere and the mesosphere.It is a district of expanding temperature in Earth's climate that is situated over the mesosphere.
The thermosphere significantly helps in ensuring the earth and making space investigation and present day types of correspondence conceivable. It additionally supports and ensures life on the planet. It reuses water, retains the sun's energy, and makes a moderate temperature.
The aurora (Northern Lights and Southern Lights) generally present in the thermosphere. It is a natural electrical marvel described by the presence of streamers of rosy or greenish light in the sky, particularly close to the northern or southern attractive shaft. The impact is caused by the communication of charged particles from the sun with iotas in the upper atmosphere.
