oxyhaemoglobin
Definition
Noun: * The oxygenated form of hemoglobin: A bright red compound formed in the lungs when hemoglobin (the protein in red blood cells) binds with oxygen. This is the primary means by which oxygen is transported from the lungs to the body's tissues.
Usage
- Primary Context: Used almost exclusively in biological, medical, and physiological contexts to describe the state of hemoglobin carrying oxygen.
- The process of gas exchange in the lungs results in the formation of oxyhaemoglobin.
- A pulse oximeter measures the saturation of oxyhaemoglobin in arterial blood.
Examples
Advanced Usage
- Oxyhaemoglobin dissociation curve: A standard graph in physiology that shows the relationship between the partial pressure of oxygen and the saturation of hemoglobin with oxygen. It demonstrates how readily hemoglobin binds to and releases oxygen under different conditions.
- The oxyhaemoglobin dissociation curve shifts to the right during exercise, facilitating oxygen release to the muscles.
Variants and Related Words
- Oxyhemoglobin (n): The American English spelling of 'oxyhaemoglobin'. The two terms are identical in meaning and usage.
- Deoxyhaemoglobin (n): The form of hemoglobin that has released its oxygen; it is darker red (often appearing bluish through blood vessels) than oxyhaemoglobin.
- Haemoglobin (n): The iron-containing protein in red blood cells responsible for oxygen transport, of which oxyhaemoglobin is one state.
- Carboxyhaemoglobin (n): The stable compound formed when hemoglobin binds with carbon monoxide instead of oxygen.
Synonyms
- Oxygenated hemoglobin: A descriptive synonym that clearly states the compound's composition and function.
Noun
-
the bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs
-
oxyhemoglobin transports oxygen to the cells of the body
