Study Notes
Blood Temperature Regulation
- Body temperature increases, sweating occurs
- Body temperature decreases, shivering occurs
Blood CO2 Regulation
- High COâ‚‚ levels: Body increases breathing rate
- Low COâ‚‚ levels: Body decreases breathing rate
Circulatory System
- Blood is 55% plasma (fluid portion) and 45% formed elements (solid portion)
- Formed elements include red blood cells and white blood cells
- Red blood cells are produced in bone marrow
- Red blood cells contain hemoglobin, which carries oxygen and carbon dioxide
Primary Function of Blood
- Transport oxygen from lungs to tissues
- Carry carbon dioxide from tissues to lungs for exhalation
