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.
Test your knowledge of identifying and differentiating blood cells, understanding Erythrocyte Sedimentation Rate (ESR) and Hematocrit (HT) values, and performing laboratory counts of RBCs and WBCs.
