The gland is an organ in the body that plays a crucial role in the endocrine system by producing and releasing hormones into the bloodstream. Endocrine glands, such as the pituitary gland, thyroid gland, and adrenal glands, secrete hormones that regulate and coordinate various bodily functions, including growth, metabolism, reproduction, and stress response. These hormones act as chemical messengers, traveling through the bloodstream to target cells or organs, where they exert their specific effects. Glands of the endocrine system work together to maintain hormonal balance and ensure the proper functioning of the body's physiological processes.

A calorie is a unit of measurement that indicates the amount of energy provided by food and beverages. When food is consumed, the body converts the calories into energy to fuel various physiological processes, such as breathing, circulation, and physical activity. The number of calories in a food item depends on its macronutrient composition: carbohydrates and proteins provide approximately 4 calories per gram, while fats provide about 9 calories per gram. Monitoring calorie intake is important for maintaining a healthy weight, as consuming more calories than the body uses can lead to weight gain, while consuming fewer can result in weight loss.
