Year 8 SELP Science - Reproduction and Homeostasis

Vocabulary flashcards covering key concepts, systems, and definitions from the Year 8 SELP Science Reproduction and Homeostasis revision checklist.

Homeostasis

The process of maintaining internal balance within the body.

Sensory Receptors

Specialised structures in the body that detect changes or stimuli in the internal or external environment.

Stimulus-Response Model

A pathway describing how a stimulus is detected by a receptor, leading to processing and a resulting response.

Feedback Loops

Biological mechanisms used to maintain homeostasis by responding to changes in conditions such as body temperature and blood glucose levels.

Central Nervous System

A major division of the nervous system consisting of the brain and spinal cord that receives, processes, and sends information.

Peripheral Nervous System

A division of the nervous system that connects the central nervous system to the limbs and organs.

Somatic Nervous System

A subdivision of the peripheral nervous system responsible for voluntary control of body movements.

Autonomic Nervous System

A subdivision of the peripheral nervous system that regulates involuntary bodily functions.

Reflex Arc

A neural pathway that controls an immediate, automatic response to a stimulus.

Endocrine System

A body system comprising glands that produce and secrete hormones to regulate various body functions.

Sexual Reproduction

A mode of reproduction involving the combination of genetic material from two parent organisms to produce offspring.

Asexual Reproduction

A mode of reproduction involving a single parent organism that produces offspring genetically identical to itself.

Internal Fertilisation

A type of fertilisation in animal reproduction where the sperm and egg meet inside the body of a parent.

External Fertilisation

A type of fertilisation in animal reproduction where sperm and egg unite outside the body of the parents.
