Which of the following hormone is released by every tissue of the body*4 pointsProstaglandinsAtrial natriuretic hormoneHCGErythropoietin

The hormone that is released by every tissue of the body among the options given is Prostaglandins.

Here's why:

1. Prostaglandins: These are hormone-like substances that are found in nearly every tissue and organ in the body. They are produced as needed and are not stored anywhere in the body. They play a crucial role in inflammation, blood flow, the formation of blood clots, and the induction of labor.

2. Atrial Natriuretic Hormone: This hormone is produced and released by the atria of the heart when the body has too much salt (sodium), which leads to an increased volume of blood in the body. It is not released by every tissue of the body.

3. HCG (Human Chorionic Gonadotropin): This hormone is produced in the placenta during pregnancy. It is not released by every tissue of the body.

4. Erythropoietin: This hormone is produced primarily by the kidneys. It stimulates the production of red blood cells by the bone marrow. It is not released by every tissue of the body.
