Ultimate Quiz On Blood Test

Fibrin is a protein that plays a crucial role in the formation of blood clots. When there is an injury or damage to blood vessels, fibrinogen (a soluble protein) is converted into fibrin by the action of an enzyme called thrombin. Fibrin forms a mesh-like structure that traps platelets and red blood cells, forming a clot to prevent excessive bleeding. This process is known as coagulation. Therefore, the statement "Fibrin is responsible for blood clot" is true.

Plasma is the correct answer because it is the non-cellular portion of the blood. It is a yellowish liquid that makes up about 55% of the total blood volume and carries various substances such as hormones, nutrients, waste products, and antibodies. Plasma also helps in regulating body temperature and maintaining blood pressure.

Platelets are derived from megakaryocytes, which are large cells found in the bone marrow. These cells undergo a process called megakaryopoiesis, where they develop and mature into platelets. Platelets are small, disc-shaped cell fragments that play a crucial role in blood clotting and the repair of damaged blood vessels. They are responsible for forming blood clots to prevent excessive bleeding and promote wound healing. Platelets also release various factors that promote inflammation and immune responses. Therefore, platelets are the correct answer in this context.

T lymphocytes, also known as T cells, are a type of white blood cell that plays a crucial role in cell-mediated immunity. They are responsible for recognizing and destroying infected or abnormal cells in the body. T lymphocytes are involved in a variety of immune responses, including viral infections, cancer, and autoimmune diseases. They can directly kill infected cells or activate other immune cells to mount an immune response. B lymphocytes, monocytes, neutrophils, and eosinophils are also important components of the immune system, but T lymphocytes specifically mediate cell-mediated immunity.

Hemoglobin consists of 5% iron (Fe). This is because iron is an essential component of hemoglobin, which is the protein molecule in red blood cells responsible for carrying oxygen throughout the body. Iron binds to oxygen in the lungs and releases it in tissues that need oxygen for various metabolic processes. Without iron, hemoglobin cannot function properly, leading to a condition called iron-deficiency anemia. Therefore, the presence of iron in hemoglobin is crucial for its oxygen-carrying capacity.

The bone marrow is indeed the place where all white blood cells originate. It is a soft, spongy tissue found inside the bones. The bone marrow contains stem cells that can differentiate into various types of blood cells, including white blood cells. These white blood cells play a crucial role in the immune system, defending the body against infections and diseases. Therefore, the statement is true.

Monocytes are a type of white blood cell, but they do not make up the largest percentage. Instead, they only consist of about 7% of white blood cells. This means that the correct answer is "they are not the most they only consist of about 7%".

IgG, IgM, and IgA are types of immunoglobulins or antibodies that are derived from globulins. Globulins are a group of plasma proteins that are involved in various immune functions, including the production of antibodies. Therefore, the correct answer is "gobulins".

The statement "White blood cells are 1 percent of the entire blood" is true. White blood cells, also known as leukocytes, make up approximately 1 percent of the total blood volume. These cells play a crucial role in the immune system, defending the body against infections and diseases. While red blood cells are the majority in blood, white blood cells are essential for maintaining overall health and fighting off pathogens.

When disposing of goblins, the element Fe (iron) is used and reused, and it is located in the spleen. The spleen is responsible for filtering blood and removing old or damaged red blood cells, so it makes sense that iron, which is essential for red blood cell production, would be present in this organ. Therefore, Fe and spleen are the correct elements and location involved in the disposal of goblins.

The correct answer is "response to bacterial infections" because granular white blood cells, also known as granulocytes, play a crucial role in the immune response against bacterial infections. These cells contain granules filled with enzymes and chemicals that help to destroy bacteria. When a bacterial infection occurs, granulocytes are recruited to the site of infection and release their granules, which can kill bacteria directly or activate other immune cells to fight against the infection. Therefore, the response to bacterial infections is one of the important functions of granular white blood cells.

Neutrophils are the most common type of white blood cells. They can be both agranular and granular, which means that they can be classified as both A and B. Neutrophils play a crucial role in the immune system by engulfing and destroying bacteria and other harmful substances. They are the first responders to infections and inflammation, making them an essential part of the body's defense mechanism.
