Study Notes
Blood Cells
- A low white blood cell count can result from bone marrow disorders, autoimmune disorders, or chronic infections.
- A high white blood cell count can result from inflammation, infection, or allergic reactions.
- The normal range for white blood cell count is between 4,500 and 10,000 cells per microliter (μL) of blood.
- Red blood cells can increase in response to high altitude, chronic lung disease, or tumors that produce erythropoietin.
- A decrease in red blood cell count can result from blood loss, chronic bleeding, or bone marrow disorders.
Erythrocyte Sedimentation Rate (ESR)
- Erythrocyte Sedimentation Rate (ESR) measures the rate at which red blood cells settle at the bottom of a test tube.
- ESR is measured by adding an anticoagulant to a blood sample, then placing it in a vertical tube and measuring the rate at which the red blood cells settle.
Urinary System
- The primary function of the urinary system is to filter waste and excess fluids from the blood.
- The ureters are muscular tubes that conduct urine from the kidneys to the bladder.
- One of the physical properties examined in urine analysis is its specific gravity, which is a measure of its concentration.
- The ureters play a crucial role in the urinary system by transporting urine from the kidneys to the bladder.
