The study of celestial objects like planets, stars, galaxies, and more.

A massive, luminous sphere of plasma held together by gravity, producing energy through fusion.

A telescope that uses lenses to bend light rays and form an image.

A telescope that uses mirrors to reflect light rays and form an image.

A telescope that detects radio waves emitted from objects in space.

A pair of pea-sized glands located below the prostate and in front of the anus. They secrete an alkaline fluid that lubricates the urethra and neutralizes any remaining urine acidity.

The male external sexual organ located above the scrotum and below the navel. It contains the urethra and its external opening.

The fluid produced by males for sexual reproduction, released during intercourse. It carries sperm and other chemicals in a liquid medium.

Two almond-shaped glands located on either side of the pelvic cavity near the top of the uterus. They produce female sex hormones like estrogen and progesterone, and release ova (eggs).

Two muscular tubes that connect the uterus to the ovaries. They have cilia that help move the ovum towards the uterus.

A hollow, pear-shaped muscular organ located behind the bladder. It's also known as the womb and is essential for carrying a developing fetus during pregnancy.

An elastic tube connecting the cervix of the uterus to the exterior of the body. It's located below the uterus and behind the bladder.

The collective name for the external female genitalia located in the pubic region. It includes the mons pubis, labia majora, labia minora, and clitoris.

Warm-blooded animals covered in hair or fur, they give birth to live young and feed their young with milk.

Cold-blooded animals with scales, they lay eggs and breathe with lungs.

Cold-blooded animals with gills, fins, and scales adapted for living in water. They breathe through gills and lay eggs.

Animals with backbones. They are classified into different groups based on their physical characteristics and systems.

Animals without backbones. They include various groups like sponges, worms, insects, and starfish.

The vertebral column is made up of 26 bones called vertebrae, grouped into five regions: cervical (neck), thoracic (chest), lumbar (lower back), sacrum, and coccyx.

The sternum (breastbone) is a thin, flat bone located in the center of the chest, connecting to the ribs.

A joint is where two bones meet, allowing for movement and flexibility. This can also be between bone and cartilage or bone and tooth.

The kidneys are bean-shaped organs that filter waste products and excess fluids from the blood to create urine. They are located on the posterior wall of the abdominal cavity.

The ureters are tubes that carry urine from the kidneys to the bladder. They run parallel to the vertebral column on either side of the body.

The urinary bladder is a sac-like organ that stores urine. It is located at the bottom of the pelvis and expands to hold urine.

The urethra is the tube that carries urine from the bladder to the outside of the body. The urethra is longer in males as it also serves to carry sperm.

Sense organs receive information from the external environment and send signals to the brain, enabling us to perceive and respond to our surroundings.

The visible part of the ear, shaped like a satellite dish, that collects sound waves and transmits them inward.

The channel connecting the outer ear to the middle ear. It amplifies sound and produces ear wax to protect the inner ear.

The chamber between the outer and inner ear. It contains small bones that translate sound waves into mechanical energy.

A thin membrane stretched between the outer and middle ear. It vibrates when sound waves hit it, converting sound energy into mechanical energy.

The smallest bone in the body, connected to the eardrum. It vibrates with the eardrum and passes sound to the incus.

A bone sitting above the malleus. It receives vibrations from the hammer and transmits them to the stapes.

The final bone in the middle ear, attached to the incus. It compresses sound waves and passes them to the inner ear.

The innermost part of the ear. It translates mechanical energy into electrical signals that the brain interprets as sound.

A wedge is a simple machine that is a triangular tool used for separating or splitting objects.

A pulley is a wheel and axle system that uses a rope or chain to lift and lower objects, reducing the effort needed.

A screw is a simple machine that is essentially a twisted inclined plane, converting rotational motion into linear motion, allowing for things to be fastened together.

A lever is a rigid bar that pivots around a fixed point called a fulcrum, allowing for multiplication of force.

A habitat is like a neighbourhood for plants and animals - the place where they live and find what they need to survive.

A population is the total number of individuals of a species living within a specific area.

A community is all the different plants and animals living together and interacting in a particular habitat.

A niche is a plant or animal's specific role and place within a habitat, influencing its interactions with other organisms.
