blood terms Flashcards
Red blood cells are called
Erythrocytes
White blood cells are called
Leukocytes
Cell fragments formed from megakaryocytes in the bone marrow via thrombopoiesis are called
Platelets/thrombocytes
WBC with cytoplasmic granules are called
granulocytes
A type of granulocyte that fights infection by engulfing and destroying bacteria and fungi; Most abundant type
Neutrophil
A type of granulocyte involved in fighting parasites and allergic reactions. It releases enzymes that combat invaders
Eosinophil
A granulocyte that plays a role in allergic responses by releasing histamine and other chemicals, causing inflammation
Basophil
A type of WBC without cytoplasmic granules
Agranulocyte
A type of agranulocyte involved in immune defense
Lymphocyte
__ cells produce antibodies, __ cell destroy infected cells
B; T
A large agranulocyte that differentiates into macrophages and dendritic cells, helping to engulf and digest pathogens and dead cells
Monocyte
Antigen (_________)
Agglutinogen
Antibody (__________)
Agglutinin
Agglutinogen refers to:
- Type A and B proteins
- anti-A and anti-B
- Type A and B proteins
antigens
Agglutinin refers to:
- Type A and B proteins
- anti-A and anti-B
- anti-A and anti-B
anitbodies
When agglutinins recognize foreign agglutinogens on RBCs they bind the RBCs together. This is called __________ (clumping)
agglutination
The extracellular liquid part of blood that carries cells and nutrients (otherwise called the matrix). Made up of 92% water, but also proteins, electrolytes, nutrients, waste products, etc:
Plasma
Plasma without clotting factors:
Serum
Universal donor
Type O
Universal recipient
Type AB
Rh-factor (D-agglutinogen) - A protein found on RBCs. If you have it, you are Rh-____, if not, Rh-_____.
positive; negative
The percentage of red blood cells in a blood sample, used to measure blood health and oxygen-carrying capacity.
Hematocrit
True or False: Anti-D agglutinins are not normally present in the blood?
True.
Anti-D agglutinins are not normally present in the blood, they only form in Rh-negative individuals who are exposed to Rh-positive blood.
A protein in red blood cells that binds to oxygen and carries it from the lungs to the body’s tissues.
Hemoglobin
A protein that forms a mesh during blood clotting to help stop bleeding
Fibrin
Structures made of DNA and proteins that carry genetic information in the form of genes.
Chromosomes
A segment of DNA that contains instructions for building a specific protein or regulating a biological function.
Gene
Different versions of a gene that can cause variations in a trait
Alleles
The genetic makeup of an individual, referring to the specific alleles inherited.
Genotype
The observable traits or characteristics of an individual, influenced by the genotype and environment.
