Answer: C. Positive feedback mechanisms are overwhelmed.
Explanation:
Homeostasis, is the maintenance of a normal internal environment, in the face of external and internal disturbances, so that the functions of cells and systems of the body are preserved. This is accomplished primarily through feedback systems, so when a system is disturbed, a diversity of local responses, systemic reflexes (rapid reactions and automatic stimuli) and long-term adjustments are activated to bring the system back to its normal equilibrium point.
Most systems are controlled by negative feedback mechanisms, with the controlled variable being able to "turn off" its release, in the same way as a thermostat controls the temperature of a room. So, in this context, too much positive feedback would be related to harmful effects, such as homeostatic imbalance.
Answer:
The loading dose of N-acetylcysteine is 8,700 mg (150 mg per 55 kilograms).
The complete cycle of treatment with N-acetylcysteine comprises 3 consecutive intravenous infusions, distributed as follows:
1 infusion: Initial dose of 150mg / kg of body weight in 200 ml of solution to pass in one hour.
2 infusion: 50 mg / k of weight in 500 ml of solution to pass in 4 hours
3 infusion: 100mg / kg of weight in 1000ml to pass in the following 16 hours.
Well its a little deeper than that. The oxygen transport is made through Hemoglobin (red blood cells) which is pumped from the heart
