Flashcard: Fundamentals of Respiratory System Biology — 18 carte

Reductionism — definition?

Explaining complex systems by their parts.

Systems Biology — approach?

Studying interactions and emergent properties of systems.

Cellular processes — focus?

Molecular mechanisms within cells.

Respiratory organs — examples?

Lungs, gills, trachea, skin.

Mechanism of breathing — process?

Muscle movements create pressure gradients for airflow.

Gas exchange — site?

Alveoli via diffusion.

Transport of O₂ — main carrier?

Hemoglobin in red blood cells.

Respiratory regulation — center?

Medulla and pons in brain.

Asthma — disorder?

Airway inflammation causing breathing difficulty.

Emergent properties — example?

Blood circulation and gas exchange.

Reductionism — role?

Led to molecular biology and biochemical insights.

Systems biology — key feature?

Integrates interactions to understand whole systems.

Molecular biology — focus?

DNA, RNA, proteins, biochemical pathways.

Alveoli — function?

Gas exchange surface in lungs.

Inspiration — muscle involved?

Diaphragm contracts and flattens.

Expiration — process?

Muscles relax, air expelled due to pressure change.

Partial pressure — influence?

Drives diffusion of gases.

Gas transport — main form?

Oxygen bound to hemoglobin, CO₂ as bicarbonate.
