🩸 What is a Blutkörperchen?
Das Blutkörperchen (neuter noun, plural: die Blutkörperchen) is a cell found in the blood of vertebrates. It's a collective term for various cell types in the blood.
The main types are:
- Rote Blutkörperchen (erythrocytes): Responsible for oxygen transport.
- Weiße Blutkörperchen (leukocytes): Part of the immune system to fight pathogens.
- Blutplättchen (thrombocytes / platelets): Important for blood clotting (although often considered cell fragments, they are sometimes colloquially included).
It is a diminutive of Blutkörper (blood body), emphasizing its small size (the '-chen' suffix indicates diminutives in German).

💬 Usage in Daily Life and Technical Language
The term "Blutkörperchen" is used in both everyday language and in medical and biological contexts.
- General Use: When speaking non-specifically about blood cells. E.g., "Er hat zu wenig rote Blutkörperchen." (He has too few red blood cells.)
- Medicine/Biology: As an umbrella term for Erythrozyten (erythrocytes) and Leukozyten (leukocytes). However, the more specific term (e.g., Leukozyt) is often preferred in technical contexts.
It's important to know that this is a fixed term. Although it refers to a cell (die Zelle - feminine), the word "Blutkörperchen" is neuter (sächlich). This is because of the ending "-chen", a diminutive suffix. All diminutives ending in "-chen" or "-lein" are neuter in German. 🚨 Remember: The ending dictates the gender here, not the meaning!
🧠 Mnemonics and Memory Aids
Remembering the Article ('das'): All German nouns ending in "-chen" are neuter ('das'). Think of other examples: das Mädchen (the girl), das Häuschen (the little house). So, Blutkörperchen must be das. It's a small, 'neutral' little thing.
Remembering the Meaning: Imagine tiny little 'bodies' (Körperchen means 'little body') swimming in the 'blood' (Blut). These are the tiny components of blood. Blut + Körperchen = Blutkörperchen (blood corpuscle).

Synonyms
- Blutzelle (f.): A common synonym, meaning 'blood cell'.
- Specific types might be used synonymously in context:
- Rotes Blutkörperchen: Erythrozyt (m.)

Antonyms
Direct antonyms don't really exist. The most logical contrast would be with Blutplasma (n.), the liquid component of blood.
Similar but Different Terms

✍️ Poem about the Blutkörperchen
Ein winzig kleines Ding,
das Blutkörperchen, flink,
Schwimmt rot durch jede Ader,
Bringt Sauerstoff, oh Wunder!
Mal weiß, zur Abwehr bereit,
Kämpft tapfer jederzeit.
Im Lebensstrom, ganz klein,
Muss dieses Körperchen sein.
A tiny little thing,
The blood corpuscle, swift,
Swims red through every vein,
Brings oxygen, oh wonder!
Sometimes white, ready to defend,
Fights bravely without end.
In life's stream, so small,
This corpuscle must be all.
❓ Little Riddle

Reise durch deinen Körper, nah und fern, fürwahr.

Ohne mich gäb's kein Leben, kein Licht.

I am tiny, but millions are there,
I travel through your body, near and far, I swear.
Sometimes red, sometimes white, I fulfill my duty,
Without me, there'd be no life, no beauty.
