Explanation:
The blood carries various substances that must be transported from one part of the body to another. Red blood cells are an important component of the blood because their function is to carry oxygen to the body tissues and exchange it for carbon dioxide, which is carried and removed by the lungs.
Erythropoiesis is the process of red blood cell (erythrocyte) production. It is stimulated by a decrease in O2 in the circulation, detected by the kidneys, which then secretes the hormone erythropoietin. This hormone stimulates the proliferation and differentiation of red blood cell precursors, which triggers an increase in erythropoiesis in hematopoietic tissues and ultimately in the production of red blood cells. <u>In adults, red blood cells are formed in the red bone marrow.</u>
In early developing fetuses, erythropoiesis occurs in the mesodermal cells of the yolk sac. In the third or fourth month, erythropoiesis moves to the liver. After seven months, erythropoiesis occurs in the bone marrow.

Answer:
See explanation below.
Explanation:
Viruses cause problems when they enter the body and begin to grow and reproduce. They can have byproducts that are harmful. Strep throat for example gives off substances that cause inflammation in the throat. Some viruses can cause serious issues such as nerve damage, like polio. So the immune system works to recognize and deal with cells that might cause harm.
The first time that a particular virus moves in and attacks the body, the immune system - and the white blood cells - might be slow to recognize the issue and take some time to swing into action. But the next time that particular germs shows up, the body is ready for it and reacts much more quickly. The body us designed this way so that harm by invading germs can be halted or minimized.
Hope this helps! Have an awesome day!! :-)
