The hormone epinephrine is released into the blood and travels to the lungs where it increases function. which organ systems are involved in this scenario?
circulatory, endocrine, and respiratory
digestive, skeletal, and urinary
endocrine, nervous, and reproductive
lymphatic, respiratory, and circulatory

The right answer is A.

Adrenaline is both a neurotransmitter and a hormone.  It is an important element of the endocrine system. It is released in the blood (circulatory system).

The secretion of adrenaline adapts the body to react to stress.  It prepares him especially for fight or flight behavior.

Acceleration of heart rhythm, vasoconstriction, elevation of blood pressure, increase of respiratory rate, hyperglycemic action, increase of cellular metabolism.

Option A - circulatory, endocrine, and respiratory

Explanation

The organ systems which are involved in this scenario is circulatory, endocrine, and respiratory. Epinephrine is a hormone is another name is adrenaline discovered in the late 1880s, Secreted from the medulla oblongata of the adrenal gland. Its main function is to elevate blood glucose level by cutting down the glycogen & another function is to increase cardiac output.

so if you eat a 2000-calorie diet, you should aim for about 225 to 325 grams of carbs per day.

but if you need to lose weight, you will get much faster results eating around 50 to 150 grams of carbs.

in fact, a popular alternative called the low-carb diet has been shown to be much more effective for weight loss than the high-carb diet that has been recommended for the past few decades.

this diet restricts your intake of carbohydrates like sugars and starches (breads, pasta, etc.) and replaces them with protein, fat and healthy vegetables.

studies show that low-carb diets reduce your appetite and make you eat fewer calories and lose weight pretty much effortlessly, as long as you manage to keep the carbs down (1trusted source).

in studies where low-carb and low-fat diets are compared, the researchers need to actively restrict calories in the low-fat groups to make the results comparable, but the low-carb groups still usually win (2trusted source, 3trusted source).

low-carb diets also have benefits that go way beyond just weight loss. they lower blood sugar, blood pressure and triglycerides. they raise hdl (the good) and improve the pattern of ldl (the bad) cholesterol (4trusted source, 5trusted source).

low-carb diets cause more weight loss and improve health more than the calorie restricted, low-fat diet still recommended by many people. this is pretty much a scientific fact at this point (6, 7, 8trusted source).

explanation:

there are many studies showing that low-carb diets are more effective and healthier than the low-fat diet that is still recommended by many people.
