Gas Exchange and Circulatory System Review

These flashcards cover key concepts related to gas exchange and the circulatory system, emphasizing definitions and physiological processes.

Gas Exchange

The process by which oxygen is delivered to cells and carbon dioxide is removed from the body.

Homeostasis

The maintenance of stable internal conditions in the body including pH and temperature.

Ventilation

The movement of air into and out of the lungs.

Perfusion

The adequate supply of oxygenated blood to tissues.

Diffusion

The process by which oxygen and carbon dioxide exchange at the alveolar-capillary membrane.

Systemic Circulation

The flow of oxygenated blood from the left ventricle to the tissues and back to the right atrium.

Pulmonary Circulation

The flow of deoxygenated blood from the right ventricle to the lungs for gas exchange.

Diaphragm

A major muscle involved in breathing that alters pressure in the chest cavity.

Intracostal Muscles

Muscles located between the ribs that assist with breathing.

Auscultation

The technique of listening to the sounds of the body, often to assess respiratory and cardiovascular health.

Signs of Respiratory Distress

Clinical indicators such as tachypnea, bradypnea, wheezing, and cyanosis.
