Hematology: Blood (Pt. 1) Flashcards
(28 cards)
Blood
The fluid found inside of blood vessels
Plasma
A watery fluid that composes approximately 55% of the blood inside humans.
Many important substances such as glucose, amino acids, hormones, and electrolytes are transported as dissolutions in the plasma.
Formed Elements
Cells or cell fragments floating in the plasma that make up approximately 45% of the blood in humans.
Include:
- Erythrocytes (Red Blood Cells)
- Leukocytes (White Blood Cells)
- Platelets (formerly called Thrombocytes).
Erythrocytes
Contain hemoglobin which is a protein that transports oxygen.
Leukocytes
Povide protection against pathogens
There five specialized types:
- Neutrophils
- Basophils
- Eosinophils
- Monocytes
- Lymphocytes
Platelets
Small platelike fragments of a larger cell and initiate hemostasis (blood-clotting process).
Hematopoiesis
The process that occurs in the red bone marrow which produces all of the formed elements.
Hematology
The diagnosis and treatment of disorders of the blood and blood-forming tissues.
Hematologist
Specializes in the treatment of bleeding disorders, cancers of the blood-forming tissues, and anemia as well as interpreting blood tests and the science of blood transfusions.
