Definition

1. Noun:
   • The pulmonary artery: The "arteria pulmonalis" is one of the two major arteries that carry deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

Usage

• The term "arteria pulmonalis" is a specific anatomical term. It is used in formal, medical, and scientific contexts to refer precisely to the pulmonary artery.
• It is typically used in singular form to refer to one of the two arteries, but the plural form "arteriae pulmonales" can be used when discussing both.

Examples

• Noun:
  • A blockage in the arteria pulmonalis can be a medical emergency.
  • The surgeon carefully repaired the damaged arteria pulmonalis.

Advanced Usage

• "Arteria pulmonalis dextra": The right pulmonary artery, which carries blood to the right lung.
• "Arteria pulmonalis sinistra": The left pulmonary artery, which carries blood to the left lung.

Variants and Related Words

• Pulmonary artery: The common English term for "arteria pulmonalis".
• Pulmonary trunk (truncus pulmonalis): The short, wide vessel that originates from the right ventricle and bifurcates into the left and right pulmonary arteries (the arteriae pulmonales).
• Pulmonary circulation: The system of blood vessels, including the arteria pulmonalis, responsible for carrying blood to and from the lungs.

Synonyms

• Pulmonary artery: The direct and most common synonym.

Notes

• The "arteria pulmonalis" is unique among arteries in the adult human body because it carries blood that is low in oxygen (venous blood), while most other arteries carry oxygen-rich blood.
• The term is of Latin origin, where "arteria" means artery and "pulmonalis" means relating to the lungs.
