Question

Which type of white blood cells have S-shaped nuclei?

Answer 1

Hint: White blood cells (WBCs), also known as leukocytes or leucocytes, are immune system cells that help the body fight infectious disease and foreign invaders. All white blood cells are produced and derived from hematopoietic stem cells, which are multipotent cells in the bone marrow.

Complete answer:
White blood cells (WBCs) are a component of the immune system that aids in the fight against infection and the defense of the body against foreign materials. White blood cells of various types are involved in recognizing intruders, killing harmful bacteria, and producing antibodies to protect your body from future exposure to certain bacteria and viruses.

White blood cells are classified into several types. They are also referred to as leukocytes.
1. Neutrophils: Neutrophils account for approximately half of the white blood cell population. They are typically the first immune system cells to respond to an invader such as a bacteria or virus. As first responders, they also send out signals that alert other immune system cells to the scene.
Because neutrophils are the primary cells found in pus, you may be familiar with their appearance. These cells only live for about eight hours after being released from the bone marrow, but your body produces 100 billion of them every day.

2. Eosinophils: Eosinophils are also involved in the fight against bacteria and are crucial in the response to parasitic infections (such as worms). They are perhaps best known for their role in allergy symptoms when the immune system overreacts to something (like pollen) that is mistakenly thought to be an invader.
These cells make up no more than 5% of the white blood cells in your bloodstream, but they are abundant in the digestive tract.

3. Basophils: Basophils, which make up only about 1% of white blood cells, play an important role in mounting a non-specific immune response to pathogens. These cells are most famous for their role in asthma. The nucleus of basophils is shaped like an S.

When these cells are stimulated, histamine and other chemicals are released. Inflammation and bronchoconstriction of the airways can occur as a result of the products.

Lymphocytes (B and T): Lymphocytes play an important role in the immune system, with T cells directly killing many foreign invaders. In contrast to the other types of white blood cells, B lymphocytes (B cells) are in charge of humoral immunity.
They produce antibodies that "remember" an infection and are ready to go if your body is exposed to it. 4 B lymphocytes play the most important role in the efficacy of most current vaccines, but in some cases (i.e. tuberculosis and pertussis vaccines). T lymphocytes are also crucial.

Monocytes: Monocytes are the immune system's garbage trucks. Monocytes make up about 5% to 12% of white blood cells in your bloodstream, but their primary function is to migrate into tissues and clean up dead cells (among other functions.)

Basophils are white blood cells that have S-shaped nuclei.

Note: Chemotherapy's effect on white blood cells, particularly neutrophils, is one of the most common and dangerous side effects. Neutrophils are essentially our immune system's "first responders." Chemotherapy-induced neutropenia, or a decrease in neutrophils, increases the risk of serious infection.
