What process takes place at the boundary between the capillaries and the alveoli?
Bronchiole
Alveol
Small blood
vessels (capillaries)
O A. An exchange of oxygen and carbon dioxide between the
circulatory and respiratory systems
O B. An exchange of blood and lymph between the circulatory and
lymphatic systems
C. Reabsorption of water into the circulatory system from the
excretory system
O D. An exchange of air between the circulatory and respiratory
systems

the endocrine system secretes hormones into blood and other body fluids. these chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. hormones provide feedback to the brain to affect neural processing. reproductive hormones affect the development of the nervous system.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
