Study Notes
Blood Classification and Composition
- Blood is classified as connective tissue, consisting of living cells and a nonliving matrix.
- Living blood cells are known as formed elements, suspended within a fluid matrix called plasma.
- The solid components of blood primarily contain erythrocytes, which make up the majority of the cell mass.
- Plasma constitutes about 55% of blood volume and is the less dense component that rises to the top.
Blood Components
- The hematocrit is the term for the volume percentage of red blood cells in blood.
- The "buffy coat" is a thin layer between erythrocytes and plasma, consisting of leukocytes and platelets, accounting for less than 1% of total blood volume.
- Blood is bright scarlet red when oxygenated and dark red when deoxygenated.
White Blood Cells
- Neutrophils are the most numerous type of leukocyte and are actively phagocytic.
- Granular leukocytes include neutrophils, eosinophils, and basophils, while agranular leukocytes consist of monocytes and lymphocytes.
- Eosinophils increase during allergy attacks, whereas basophils release histamine during inflammatory responses.
- Monocytes are elevated during prolonged infections.
Red Blood Cells
- Red blood cells (RBCs), or erythrocytes, lack nuclei and are crucial for transporting oxygen due to their hemoglobin content.
- The stimulus for increased red blood cell production is low oxygen levels in the blood.
- Blood viscosity decreases when there is a reduction in red blood cell count.
Blood Cell Regulation and pH
- Diapedesis is the process by which white blood cells exit blood vessels to perform immune functions.
- Leukopenia refers to an abnormal decrease in the number of white blood cells.
- Normal blood pH ranges from 7.35 to 7.45, maintaining acid-base homeostasis.
Blood Volume
- The average adult cardiovascular system contains approximately 5.5 liters of blood, vital for bodily functions.
Lymphocyte Abundance
- The order of abundance for lymphocyte types is: Neutrophil, Lymphocyte, Monocyte, Eosinophil, Basophil.
