Which of the following scenarios best exemplifies the concept of opposite reactions working together to maintain homeostasis in the human body?
A. The decline in blood calcium levels triggering the release of parathyroid hormone, which enhances calcium absorption in the intestines
B. Pro-coagulant and anticoagulant pathways to regulate blood clotting
C. The conversion of angiotensin I to angiotensin II, which promotes increased sodium and water reabsorption in the kidneys
D. The process of erythropoiesis increasing during times of chronic hypoxia

Answer (2)

Homeostasis in the human body involves opposing reactions that regulate various physiological processes. The regulation of blood clotting through pro-coagulant and anticoagulant pathways best exemplifies this balance. This interaction ensures that the system can respond appropriately to injuries without causing harm from either excessive bleeding or clot formation. ;
