What Is the Structure and Function of the Human Pulse?
The human pulse is a rhythmic beat felt at various points on the body, reflecting the regular pumping action of the heart. It is a crucial indicator of health, giving insight into cardiovascular and overall bodily status. Understanding how the human pulse works, its normal values, and what affects it is essential for students and healthcare professionals alike.
Human Pulse Definition
Human pulse refers to the palpable rhythmic expansion and contraction of an artery as blood is forced through it by heart contractions. In simple terms, it is the physical sensation of the heart’s beating, usually measured at the wrist or neck. The pulse rate, counted as beats per minute (bpm), provides vital information about heart function and overall well-being.
How is the Human Pulse Measured?
The human pulse is commonly measured using the index and middle fingers placed gently on specific arteries. The most typical sites are the radial artery at the wrist and the carotid artery in the neck. It is counted for 15 seconds and multiplied by four, or directly for a full minute for accuracy, especially when assessing irregularities.
- Radial pulse: Located on the inner wrist below the thumb.
- Carotid pulse: Found on either side of the neck, beside the windpipe.
- Brachial pulse: On the inner side of the elbow, used in infants.
- Femoral pulse: In the groin region.
- Dorsalis pedis pulse: On the top of the foot.
Accurately recording pulse is essential in medical scenarios and helps in identifying circulatory and heart-related issues. You can deep-dive into how the heart works by exploring the structure and function of the human heart topic on Vedantu.
