Which form of hypoxia occurs when body cells are unable to use o2 even though adequate amounts are delivered? (this type of hypo
Oksana_A [137]

Histotoxic hypoxia, which happens whenever body cells are not able to utilize oxygen while receiving sufficient amounts, is typically caused by metabolic toxins like cyanide.

What is hypoxia?

  • Hypoxia is a state in which there is insufficient oxygen reaching the tissues throughout the system or a specific area of the body.
  • Although fluctuations in arterial concentrations of oxygen are frequently associated with clinical conditions, they can also occur naturally during severe physical activity or hypoventilation training.

When does Histotoxic hypoxia occur?

When the supply of gas entering the cell is adequate, but the cells are unable to utilize the oxygen properly due to deactivated oxidative phosphorylation enzymes, histotoxic hypoxia develops. Ingestion of cyanide may result in this.
