Study Notes

Digestive System

Major organs: Mouth, esophagus, stomach, small intestine, large intestine, rectum, anus, liver, gallbladder, pancreas
Role: Breaks down food into smaller molecules that the body can absorb and use for energy, growth, and repair.

Circulatory System

Major organs: Heart, blood vessels (arteries, veins, capillaries)
Role: Transports oxygen, nutrients, and hormones to cells throughout the body; removes waste products from cells.
Technologies for heart diseases: Stents to open blocked arteries, pacemakers to regulate heart rhythm, heart transplants to replace a failing heart.
Technologies for organ transplantations: Immunosuppressant drugs to prevent organ rejection, advanced surgical techniques to minimize damage during transplantation.

Excretory System

Major organs: Kidneys, ureters, bladder, urethra
Role: Removes waste products from the blood and eliminates them from the body in urine.
Technology for treating and preventing kidney diseases: Dialysis to filter the blood when the kidneys are not working properly.

Skeletal/Muscular System

Major organs: Bones, cartilage, tendons, ligaments, muscles
Role: Provides support and structure to the body, enables movement, protects vital organs.
Advancements in technology for artificial joints/limbs: Prosthetic limbs with advanced materials and technology that provide improved functionality and appearance, minimally invasive surgical techniques for joint replacement.

Respiratory System

Major organs: Nose, pharynx, larynx, trachea, bronchi, lungs, alveoli
Role: Takes in oxygen and releases carbon dioxide during breathing.
Technology for treatment of asthma: Inhalers to deliver medication directly to the lungs, anti-inflammatory medications to reduce airway inflammation, immunotherapy to desensitize the immune system to triggers.

Reproductive System

Major organs: Male: testes, epididymis, vas deferens, prostate gland, penis. Female: ovaries, fallopian tubes, uterus, vagina, cervix.
Role: Produces sex hormones and gametes (sperm and eggs) for reproduction.

Earth's Crust

Structure of the Earth: Crust, mantle, outer core, inner core.
Types of weathering: Physical weathering (breaking down rocks into smaller pieces) - examples: freezing and thawing, abrasion. Chemical weathering (changing the chemical composition of rocks) - examples: acid rain, oxidation. Both form a range of landforms like canyons, caves, and cliffs.

Agents of Erosion

Agents of erosion: Wind, water, ice, gravity - these move weathered material to form landforms like valleys, sand dunes, and deltas.

Identifying Minerals

Definition: Minerals are naturally occurring, inorganic solids with a defined chemical composition and crystal structure.
Practical: Identifiable by physical properties like colour, streak, hardness, lustre, cleavage, and fracture.

Types of Rocks and the Rock Cycle

Sedimentary rocks: Formed from sediments that are compacted and cemented together - examples: sandstone, and limestone.
Igneous rocks: Formed when molten rock (magma or lava) cools and solidifies - examples: granite, and basalt.
Metamorphic rocks: Formed when existing rocks are transformed by heat, pressure, or chemical reactions - examples: marble, slate.
Rock cycle: A continuous process in which rocks are transformed from one type to another over time.

Natural and Man-Made Resources

Natural resources: Resources found in nature, such as minerals, water, forests, and fossil fuels.
Man-made resources: Resources created by humans, such as plastic, steel, and concrete.
Investigate The importance of both resources in everyday life.

Renewable and Non-Renewable Resources

Renewable resources: Resources that can be replenished naturally over a relatively short period, such as solar energy, wind energy, and hydropower.
Non-renewable resources: Resources that are finite and cannot be replenished naturally within a human timescale, such as fossil fuels, minerals, and nuclear energy.

Extraction of an Ore

Impacts of mining:
- Society: Provides jobs and economic benefits but can also lead to social disruption and conflict.
- Environment: This can cause habitat destruction, pollution, and land degradation.

Strategies to Conserve Non-Renewable Resources

Alternative resources: Using renewable energy sources like wind and solar power in place of fossil fuels.

Differing Viewpoints and Technological Development in the Extraction of Resources

Differing viewpoints: Different groups have different perspectives on how to manage and extract resources due to factors such as culture, economics, and environmental concerns.
Technological development: Technological advancements have greatly changed the ways resources are extracted, sometimes with positive and negative impacts.
Aboriginal and Torres Strait Islander knowledge: Plays a key role in sustainable resource management based on understanding local ecosystems, traditions, and relationships with the land.

Importance: Mining is a significant source of employment, contributing to various industries and economies.

Fossil and Geological History

Importance of fossils: Provide evidence of past life and environments, aiding in understanding geological history and evolution.
