Study Notes
ECG (Electrocardiogram)
- The P wave represents the atrial depolarization, which is the contraction of the atria.
- The normal heart rate in a regular rhythm is between 60-100 beats per minute.
Spirometry
- The letter B represents the point of expiration on a spirometer graph.
- The Residual volume (RV) is the volume of air that remains in the lungs after a maximal exhalation.
Osmotic Fragility Test
- The normal value range for males in the Osmotic fragility test is 0.48-0.50%.
Physiology
- Physiology is the study of the functions and processes that occur within living organisms.
Cells
- The basic unit of both structure and function in living organisms is the cell.
- In multi-cellular organisms, groups of cells form tissues.
- The cell is the smallest structure of living matter capable of functioning as an independent unit.
- In unicellular organisms, cells perform vital processes such as nutrition, metabolism, and reproduction.
