Cardiac and Circulatory System

Cardiovascular System: Comprises the heart and blood vessels for circulation.
Atria: Two upper heart chambers; right atrium receives unoxygenated blood, left atrium sends oxygen-rich blood to the body.
Ventricles: Two lower heart chambers; right ventricle sends blood to the lungs, left ventricle sends oxygenated blood to the body.
Arteries: Vessels that carry blood away from the heart.
Pulmonary arteries: Carry blood from the right ventricle to the lungs.
Coronary arteries: Supply blood to the heart muscle itself.

Respiratory System Components

Respiratory System: Includes the nose, mouth, throat, lungs, and muscles to facilitate gas exchange.
Alveoli: Microscopic sacs in lungs where gas exchange occurs.
Diaphragm: Major respiratory muscle separating the chest and abdominal cavities; aids in breathing.
