Hormonal coordination in humans key terms

carbohydrate-controlled diet

A dietary approach that limits carbohydrate intake to help manage blood glucose levels, particularly in individuals with Type 2 diabetes.

exercise

Physical activity that can improve insulin sensitivity and aid in the regulation of blood glucose levels, beneficial for individuals with Type 2 diabetes.

obesity

A condition characterized by excessive body fat, which increases the risk of developing various health issues, including Type 2 diabetes.

Type 2 diabetes

A metabolic disorder where the body becomes resistant to insulin or doesn't produce enough insulin, often associated with obesity.

Type 1 diabetes

A disorder in which the pancreas fails to produce enough insulin, leading to high blood glucose levels.

Type 2 diabetes

A disorder where body cells no longer respond properly to insulin, often associated with obesity and lifestyle factors.

diabetes

A medical condition characterized by high blood glucose levels due to insufficient insulin production or ineffective use of insulin by the body.

obesity

A condition of excessive body fat that increases the risk of health problems, often linked to lifestyle choices and dietary habits.

blood glucose concentration

The level of glucose present in the blood, which is monitored and regulated by hormones such as insulin and glucagon.

graph interpretation

The process of analyzing graphical representations of data to understand trends and changes in blood glucose levels before and after meals or treatments.

glucagon

A hormone secreted by the pancreas that raises blood glucose levels by promoting the conversion of glycogen to glucose when blood glucose concentration is too low.

pancreas

An organ that monitors and regulates blood glucose concentration by secreting hormones such as insulin and glucagon.

glucagon

A hormone secreted by the pancreas that stimulates the conversion of glycogen back into glucose when blood glucose levels are low.

glycogen

A stored form of glucose found in the liver and muscles, which can be converted back into glucose when needed.

insulin

A hormone secreted by the pancreas that lowers blood glucose concentration by facilitating the uptake of glucose into cells.

glucagon

A hormone secreted by the pancreas that raises blood glucose concentration by stimulating the conversion of glycogen to glucose in the liver.

osmosis

The movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

ion balance

The regulation of ion concentrations in the body to maintain homeostasis and prevent cellular dysfunction.

water loss

The process by which water is expelled from the body, particularly through exhalation from the lungs and evaporation from the skin in sweat.

sweat

A fluid produced by sweat glands in the skin that helps regulate body temperature and facilitates water loss.

sweat

A fluid produced by sweat glands in the skin that helps regulate body temperature and excretes water, ions, and urea.

urea

In Maintaining water and nitrogen balance in the body (biology only), urea means a waste product formed from the breakdown of proteins, which is excreted in sweat and urine. This matters in Hormonal coordination in humans because it supports the learning objective to describe water, ions and urea loss from the skin in sweat. Use urea only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

water loss

The process by which water is expelled from the body, particularly through the lungs during exhalation and from the skin in sweat.

osmosis

The movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration, which affects water levels in body cells.

kidneys

In Maintaining water and nitrogen balance in the body (biology only), kidneys means organs that filter blood to remove excess water, ions, and urea, producing urine. This matters in Hormonal coordination in humans because it supports the learning objective to describe the kidneys as organs that remove excess water, ions and urea from the blood in urine. Use kidneys only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

internal balance

The state in which the body's internal environment remains stable and optimal for cellular function, achieved by regulating water, ions, and urea levels.

excess removal

The process of eliminating surplus water, ions, and urea from the body to maintain homeostasis and prevent toxicity.

proteins

Large molecules made up of amino acids that are essential for the structure and function of body tissues.

amino acids

The building blocks of proteins, which are produced during the digestion of proteins and cannot be stored in excess.
