Biology: Blood Composition and Disorders

What is the biggest component of blood?

Where are red blood cells primarily produced in the body?

What causes the body to produce antibodies?

What is the medical term for the condition characterized by low levels of oxygen in the blood?

What disorder can occur when a rhesus positive male has a second child with a rhesus negative female?

Which of the following terms describes the phenomenon where blood cells become aggregated into larger clumps?

What is the primary origin of blood cell production in adults?

In the context of blood types, what is a common risk associated with erythroblastosis?

Which component of the immune response specifically targets and neutralizes foreign invaders like infectious cells?

What condition is characterized by a deficiency in hemoglobin leading to reduced oxygen transport in the blood?

Blood Composition

Plasma makes up the largest proportion of blood.
Red blood cells, white blood cells, and platelets are suspended in plasma.

Blood Cell Production

Bone marrow is the site of blood cell production.

Immune Responses

Antigens are markers found on the surface of infectious cells.
Antibodies are proteins produced by the immune system to fight foreign cells.

Blood Disorders

Anemia is a condition characterized by low oxygen levels in the blood, usually due to low hemoglobin levels.
Agglutination is the clumping of blood cells, often triggered by incompatible blood types.
Erythroblastosis fetalis is a disorder that occurs when a Rh-negative mother carries a Rh-positive fetus, particularly during a second pregnancy.

Blood Composition

Plasma is the primary component of blood, comprising around 55% of its volume.

Hematopoiesis

Bone marrow, a soft tissue found within bones, is the site of blood cell production.

Immune Response

Antigens, unique identifiers located on the surface of cells, trigger an immune response when foreign cells enter the body.
Antibodies, specialized proteins produced by the immune system, recognize and bind to antigens, marking foreign cells for destruction.

Blood Disorders

Anemia is a condition characterized by low levels of hemoglobin, the protein in red blood cells responsible for oxygen transport. This deficiency leads to reduced oxygen delivery to the body's tissues.
Agglutination, the clumping together of blood cells, can occur when incompatible blood types are mixed, leading to complications.
Erythroblastosis fetalis, a serious condition affecting newborns, can occur when a Rh-negative mother carries a Rh-positive fetus. The mother's immune system may develop antibodies against the fetal blood cells, leading to hemolysis (destruction of red blood cells) in the fetus.

This quiz covers essential aspects of blood composition, including plasma, blood cells, and the role of bone marrow in production. It also explores immune responses involving antigens and antibodies, as well as various blood disorders such as anemia and erythroblastosis fetalis.
