Question

The condition of reduced oxygen supply to tissues is called:

• A. Hypercapnia
• B. Hypoxia
• C. Asphyxia
• D. Cyanosis

Hint:

Hypoxia can be categorized as hypoxic hypoxia (low atmospheric oxygen), anaemic hypoxia (low haemoglobin), or stagnant hypoxia (poor blood flow).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Medical terminology provides specific names for the status of gas levels within the blood and tissues. Reduced oxygen availability can stem from various environmental or physiological causes.

Step 2: Detailed Explanation:
1. Hypoxia: This term describes a condition where the oxygen supply is insufficient at the tissue level to maintain normal physiological functions.
2. Hypercapnia: This refers to an abnormally high level of carbon dioxide (\(CO_2\)) in the blood.
3. Asphyxia: A condition characterized by the severe deprivation of oxygen and an increase in carbon dioxide, often leading to unconsciousness or death.
4. Cyanosis: A physical sign characterized by a bluish or purplish discoloration of the skin or mucous membranes, which occurs when blood is poorly oxygenated.

Step 3: Final Answer:
Reduced oxygen supply to tissues is specifically called Hypoxia.
