Protective layers surrounding the central nervous system (CNS).

Inner layer of the meninges, closely adhering to the brain and spinal cord.

Middle layer of the meninges, web-like structure that suspends the brain.

Fluid in the subarachnoid space that cushions the brain and spinal cord.

A substance lining the alveoli that reduces surface tension and keeps them open.

Process of breaking down glucose to produce ATP, the energy currency of cells.

Adenosine triphosphate, energy currency produced during cellular respiration.

Anaerobic does not require oxygen and is less efficient; aerobic uses oxygen and is more efficient.

Pathway of blood entering and exiting the heart via specific valves and chambers.

Kidneys filter waste, balance fluids, and synthesize hormones for blood regulation.

Mineral crystallization inside kidneys, causing pain and blockage.

A progressive loss of kidney function often caused by high blood pressure.

Skeletal (voluntary), cardiac (involuntary), and smooth (involuntary) muscle types in the body.

Involuntary muscle found only in the heart, with striated fibers that interlock for efficiency.

The process of maintaining a stable internal environment despite external changes.

Cells that sense changes in the environment and send signals to the control center.

The part of the body (like the brain) that processes information and generates responses.

A mechanism that counteracts changes in the body to maintain stability, e.g., thermoregulation.

The transfer of oxygen and carbon dioxide between alveoli and capillaries during respiration.

Maintaining optimal blood pressure through vessel resistance, cardiac output, and fluid balance.

Sensors in blood vessels that monitor blood pressure and trigger appropriate responses.

The amount of blood the heart pumps in one minute, calculated as heart rate times stroke volume.

Kidneys control sodium and water levels to regulate blood volume and pressure.
