Bones grow, repair, and adapt to stress.

Mature cells maintaining bone structure and responding to stress.

Comprises limbs; attaches to the axial skeleton.

Includes skull, spine, and ribcage; central axis.

Holds bones together, enabling movement and stability.

Produces red blood cells; abundant in children.

Reaches adult form but continues to remodel.

Outer layer providing strength and protection.

Stores fat; found in long bone cavities.

Produces red blood cells; abundant in children.

Stores fat; found in long bone cavities.

Bones heal themselves through regeneration.

Bones are alive and constantly changing.

Outer layer providing strength and protection.

Flexible tissue cushioning joints and providing structure.

Bone formation continues at ends, forming growth plates.

Comprises limbs; attaches to the axial skeleton.

Example includes the scapula.

All living organisms are made up of cells.

The scientist who discovered cells by observing cork.

Groups of similar cells working together to perform specific functions.

Structures made up of different types of tissues that work together to perform a specific function.

A group of organs working together to perform a complex function.

Connective tissue supports, binds, and protects other tissues in the body.

Muscle tissue is responsible for movement in the body.

Nervous tissue transmits signals throughout the body to coordinate actions and communication.

Epithelial tissue covers body surfaces and lines cavities, acting as a protective barrier.

The skeletal system is the body's framework, made up of bones, providing support and protection.

The muscular system enables movement through muscle contraction, allowing us to walk, run, and perform actions.

The circulatory system is responsible for transporting blood, nutrients, and oxygen throughout the body.

The respiratory system facilitates gas exchange, taking in oxygen and releasing carbon dioxide.

The urinary system removes waste products from the blood and regulates water balance.

The digestive system breaks down food, helping to extract nutrients and absorb them into the body.

The endocrine system produces hormones that regulate functions throughout the body, like growth and metabolism.

The lymphatic system plays a crucial role in the immune system, filtering fluid and fighting infections.

The reproductive system is involved in the process of reproduction, producing offspring.

Hard structures forming the skeleton, providing support, protection, and allowing movement through joints.

Flexible connective tissue found in joints, cushioning bones and providing support.

Ligaments are tough, fibrous connective tissues that connect bone to bone at joints, providing stability.

Tendons are tough, fibrous connective tissues that connect muscles to bones, allowing for movement.

The dense, hard outer layer of bone that provides strength and protection.

Lightweight tissue found inside bones, making them less dense and more flexible.

The skull, vertebral column, and rib cage form the axial skeleton, the central axis of the body.

The limbs and girdles attached to the axial skeleton form the appendicular skeleton, allowing for movement and reaching.

Mature bone cells that maintain bone tissue, ensuring its strength and structure.

Bone-forming cells that deposit bone matrix, building new bone tissue.

Bone-resorbing cells that break down bone tissue, helping to remodel and repair bones.

Red marrow is found in bones and responsible for producing red blood cells and platelets.

The "powerhouses" of the cell, responsible for cellular respiration. They produce ATP (adenosine triphosphate), the energy currency of the cell. They possess their own DNA and ribosomes. They have a double membrane structure, with the inner membrane being highly folded to increase surface area for reactions.

Membrane-bound sacs that store materials. They contain digestive enzymes that break down waste materials, cellular debris, and foreign invaders. They maintain a low pH internal environment, which helps to enhance enzyme activity.

A rigid outer layer surrounding plant cells that provides support and structure. It is primarily composed of cellulose.

A network of protein filaments throughout the cytoplasm that provides structural support, aids in the movement of materials within the cell, and is involved in cell division.

Cells that lack a nucleus and other membrane-bound organelles. They have a nucleoid region containing DNA, and are smaller in size than eukaryotic cells. Examples include bacteria and archaea.

The fundamental units of life, capable of carrying out all life processes.

A selectively permeable barrier that encloses the cell, controlling what enters and exits.

A gel-like substance that fills the cell, containing organelles and playing a crucial role in metabolic reactions.

A membrane-bound organelle that houses the cell's genetic material (DNA), controlling the cell's activities.

Complex molecular machines responsible for protein synthesis, found free in the cytoplasm or attached to the endoplasmic reticulum.

An extensive network of interconnected membranes extending throughout the cytoplasm, involved in protein synthesis, modification, and lipid synthesis.

A stack of flattened membrane-bound sacs that modifies, sorts, and packages proteins and lipids for secretion.

A network of protein filaments that provides structural support to the cell and aids in movement.
