Definition

Noun: - Oxygen-rich blood in the circulatory system: Arterial blood is the blood found within arteries. It is typically bright red due to its high oxygen content, having been oxygenated in the lungs. The sole exception is the blood within the pulmonary artery, which carries deoxygenated blood from the heart to the lungs.

Usage

Arterial blood is a technical term used primarily in medical, biological, and physiological contexts to describe the state and location of blood based on its gas content (primarily oxygen and carbon dioxide) and pathway within the body.

Examples

• The doctor ordered a test to analyze the gases in the patient's arterial blood.
• Arterial blood is pumped from the heart to deliver oxygen to tissues throughout the body.
• A comparison between arterial blood and venous blood reveals key differences in oxygen saturation.

Advanced Usage

• Arterial blood gas (ABG): A common diagnostic test that measures the acidity (pH) and the levels of oxygen and carbon dioxide in arterial blood.
  • The ABG analysis provided crucial information about the patient's respiratory function.

Variants and Related Words

• Artery (n): A blood vessel that carries blood away from the heart.
• Arterial (adj): Pertaining to an artery or arteries (e.g., , ).

Synonyms

• Oxygenated blood (Note: This is not a perfect synonym, as it describes the property rather than the specific location, and it excludes the blood in the pulmonary artery.)

Antonyms

• Venous blood: Blood found in veins, which is typically lower in oxygen and higher in carbon dioxide.

Noun

1. blood found in arteries
   • except for the pulmonary artery the arterial blood is rich in oxygen
