T/F
Circulatory shock is any state in which cardiac output is insufficient to meet the body’s metabolic needs
True
T/F
Pressure sensors, chemical receptors, and activity receptors are located in various area of the body to regulate our heart rate.
True
T/F
Oxygen and carbon dioxide bind to different parts of hemoglobin.
True
