Graphic Design Theory explores the principles and philosophy behind visual communication, aiming to understand how design elements can be used effectively to convey messages and evoke emotions. This discipline intersects with other fields like psychology and semiotics, providing designers with the foundational knowledge necessary to create impactful and meaningful designs.
The endocrine system is a network of glands that produce and release hormones to regulate various bodily functions, including metabolism, growth, and mood. It plays a crucial role in maintaining homeostasis and coordinating the body's response to internal and external stimuli.

Homeostasis is the physiological process by which biological systems maintain stability and equilibrium in response to changing external conditions. It is essential for the survival of organisms, enabling them to regulate internal environments such as temperature, pH, and ion concentrations to ensure optimal functioning.
Feedback mechanisms are processes that use the conditions of one component to regulate the function of another, often maintaining homeostasis or equilibrium within a system. These mechanisms can be positive, amplifying changes, or negative, counteracting deviations to stabilize the system.
Hormonal imbalance occurs when there is too much or too little of a hormone in the bloodstream, which can significantly affect bodily functions and overall health. It can lead to a wide range of symptoms depending on which hormones are affected, including weight gain, mood swings, fatigue, and changes in appetite or sleep patterns.
Concept
Metabolism is the set of life-sustaining chemical reactions in organisms that enable them to grow, reproduce, maintain their structures, and respond to environmental changes. It involves two main processes: catabolism, which breaks down molecules to produce energy, and anabolism, which uses energy to construct components of cells such as proteins and nucleic acids.
Reproductive health encompasses a state of complete physical, mental, and social well-being in all matters relating to the reproductive system at all stages of life. It implies that individuals have a safe, satisfying, and informed approach to sexual and reproductive life, with the capability to reproduce and the freedom to decide if, when, and how often to do so.
The stress response is an evolutionary survival mechanism that prepares the body to face perceived threats by activating the autonomic nervous system and releasing stress hormones like adrenaline and cortisol. While beneficial in acute situations, chronic activation of the stress response can lead to negative health outcomes such as cardiovascular disease, anxiety, and depression.
Circadian rhythms are natural, internal processes that regulate the sleep-wake cycle and repeat roughly every 24 hours, influencing various physiological functions in living organisms. These rhythms are driven by a biological clock and can be affected by environmental cues like light and temperature, impacting overall health and well-being.
Hormone receptors are specialized proteins located on the surface of or inside cells, which bind to specific hormones and trigger a response in the cell. They play a crucial role in regulating physiological processes by mediating the actions of hormones, influencing growth, metabolism, and homeostasis.
Hormonal profiling is a diagnostic tool used to assess the levels and balance of hormones in the body, providing insights into various health conditions and guiding personalized treatment plans. It plays a crucial role in understanding endocrine disorders, fertility issues, and the effects of aging, stress, and lifestyle on hormonal health.
Unconjugated estriol is a form of the hormone estriol that is not bound to any other molecules, and it is often measured during pregnancy as part of the triple or quadruple screening tests to assess the risk of certain chromosomal abnormalities in the fetus, such as Down syndrome. It is produced by the placenta and fetal liver, and its levels can provide important information about fetal well-being and development.
Endocrine function tests are diagnostic tools used to assess the performance of the endocrine glands by measuring hormone levels in the body. These tests help diagnose hormonal imbalances and conditions such as diabetes, thyroid disorders, and adrenal insufficiency.
Hormonal assays are critical diagnostic tools used to measure the levels of hormones in the body, providing essential information for diagnosing and managing a wide range of endocrine disorders. These assays utilize various techniques, including immunoassays and chromatography, to detect and quantify hormones with high specificity and sensitivity.
Biomarkers of organ dysfunction are specific biological indicators that can be measured to assess the health and function of organs, providing critical insights into the presence, severity, and progression of diseases affecting those organs. These biomarkers are essential for early diagnosis, monitoring treatment efficacy, and predicting outcomes in patients with organ-related conditions.
