Purkinje fibers are connected with the impulse conducting system of:
Correct answer: A. Heart
- A. Heart
- B. Brain
- C. Skin
- D. Nephron
Explanation
The correct answer is Option A: Heart. Purkinje fibers are a critical component of the heart's impulse conducting system. They rapidly transmit electrical impulses, which orchestrate the nearly simultaneous contraction of the ventricles, facilitating efficient blood circulation. In contrast, the brain relies on neurons for impulse transmission, the skin uses nerve endings for sensory signaling, and the nephron uses epithelial cells for its physiological processes.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
