Study Notes
Cells: The Basic Living Unit
- The cell is the basic living unit of all organisms.
Cell Size
- An average-sized cell is about 1/25000 the size of the smallest dot you can make on a sheet of paper with a sharp pencil.
Cell Structure
Generalized Cell Parts
- A generalized cell consists of three main regions or parts:
Blood Cells
White Blood Cells
- White blood cells, also known as leukocytes, function to protect the body against infection and disease by identifying and destroying foreign substances and pathogens.
Red Blood Cells
- Red blood cells, also known as erythrocytes, function to carry oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs.
