Energy in the body is obtained from the food we eat and is converted into a form called ATP. This ATP is used to power essential physiological processes such as muscle contraction, nerve signaling, and cell growth and repair. The body constantly produces and uses ATP to maintain its functions and keep us alive and healthy.
Around 90% of the energy that enters an organism is typically used for metabolic processes like growth, maintenance of body functions, and reproduction. This energy is converted into various molecules that the organism needs for its physiological processes.
Glucocorticoids help regulate various physiological processes in the body by binding to specific receptors in cells and influencing gene expression. This can affect metabolism, immune response, and stress response, among other functions.
The source of energy for most activities in the human body is glucose. Glucose is derived from carbohydrates in our diet and is converted into ATP through cellular respiration to supply energy for various physiological processes.
Physiological basis refers to the underlying physical and chemical processes within the body that support various functions and activities. It encompasses how cells, tissues, organs, and systems work together to maintain homeostasis and enable the body to respond to changes in the internal and external environment. Studying the physiological basis of different processes helps us understand how the body functions and how disruptions in these processes can lead to disease.
Hormones are released in response to feedback mechanisms that help regulate various physiological processes in the body.

The metabolic system encompasses various physiological processes that occur in multiple body systems, namely the endocrine, digestive, and respiratory systems. These systems work together to regulate metabolism, energy production, and nutrient utilization in the body.

Metabolism refers to the chemical processes in the body that convert food into energy. It involves breaking down nutrients and molecules to release energy for various physiological functions, such as growth, repair, and movement. Metabolism can be influenced by factors like genetics, age, body composition, and physical activity level.
Endocrine glands secrete hormones directly into the blood stream to regulate various physiological processes in the body.
An example of an endogenous substance is a hormone produced naturally within the body, such as insulin or estrogen. These substances are created by the body's own internal processes and play important roles in maintaining various physiological functions.
Osmosis is important to the human body because it helps maintain the balance of fluids inside and outside of cells. This process allows nutrients and waste products to move in and out of cells, helping to regulate cell function and overall body function. Osmosis impacts various physiological processes such as hydration, nutrient absorption, and waste removal, all of which are essential for the body to function properly.
The energy currency for the body is adenosine triphosphate (ATP). ATP is produced during cellular respiration and is used as a source of energy for various biological processes in the body.
The total changes that take place during physiological processes are called homeostasis. Homeostasis involves the regulation of various body functions to maintain a stable internal environment despite external changes.
