Hormonal coordination in humans key terms

endocrine system

A system of glands that secrete hormones directly into the bloodstream to regulate various bodily functions.

hormones

Chemical messengers produced by glands in the endocrine system that travel through the bloodstream to target organs, influencing physiological processes.

hormones

Chemical messengers that travel in the bloodstream to target organs, where they produce specific effects.

target organs

Specific organs that respond to hormones, receiving signals that trigger particular physiological effects.

Hormonal coordination

A slower and longer-lasting response mechanism in the body that uses hormones to regulate physiological processes.

Nervous coordination

A rapid response mechanism in the body that uses electrical signals transmitted through neurons to control immediate actions.

pituitary gland

The master gland of the endocrine system that secretes several hormones directly into the bloodstream.

hormones

Chemical messengers produced by glands in the endocrine system that regulate various functions in the body.

pituitary hormones

Hormones secreted by the pituitary gland that regulate the function of other endocrine glands.

stimulate

To encourage or activate the release of hormones from other glands in the endocrine system.

endocrine glands

Glands that secrete hormones directly into the bloodstream, including the pituitary gland, pancreas, thyroid, adrenal gland, ovaries, and testes.

hormones

Chemical messengers produced by endocrine glands that travel through the bloodstream to target organs, regulating various body functions.

hormones

Chemical messengers that are secreted by glands in the endocrine system and travel in the bloodstream to target organs, coordinating various body functions.

chemical messengers

Substances, such as hormones, that transmit signals between cells and organs to regulate physiological processes in the body.

target organs

In Human endocrine system, target organs means specific organs that hormones travel to in order to exert their effects. This matters in Hormonal coordination in humans because it supports the learning objective to apply knowledge of target organs to explain why hormones affect only specific tissues. Use target organs 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.

hormonal specificity

The concept that hormones only affect particular tissues or organs that have the appropriate receptors.

Pancreas

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

Blood glucose concentration

The level of glucose present in the blood, which is controlled by the pancreas to maintain homeostasis.

Insulin

A hormone secreted by the pancreas that helps regulate blood glucose levels by facilitating the uptake of glucose into cells.

Pancreas

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

insulin

A hormone produced by the pancreas that facilitates the uptake of glucose from the blood into cells.

glucose transport

The process by which glucose moves from the bloodstream into cells, primarily facilitated by insulin.

insulin

A hormone secreted by the pancreas that regulates blood glucose levels by facilitating the conversion of excess glucose into glycogen.

glycogen

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

Type 1 diabetes

A disorder characterized by the pancreas failing to produce sufficient insulin, leading to high blood glucose levels.

Insulin

A hormone produced by the pancreas that regulates blood glucose levels by facilitating the uptake of glucose into cells.

insulin injections

Insulin injections are a method of delivering insulin to individuals with Type 1 diabetes to help regulate blood glucose levels.

blood glucose concentration

Blood glucose concentration refers to the amount of glucose present in the bloodstream, which needs to be maintained within a specific range for proper bodily function.

Type 2 diabetes

A disorder in which body cells no longer respond properly to insulin, leading to elevated blood glucose levels.

insulin

A hormone produced by the pancreas that regulates blood glucose levels by facilitating the uptake of glucose into cells.
