Which physiological challenge arises in hibernating mammals due to reduced erythrocyte deformability?

💡 Explanation

Microvascular occlusion risk greatly increases because reduced temperature decreases erythrocyte flexibility impacting blood flow via altered membrane protein configuration; therefore, cells become rigid, rather than staying flexible for narrow capillaries preventing blood clots under hypothermic conditions.
