Question

Elucidate three physiological changes that occur due to ageing.

Answer 1

1. Loss of Muscle Mass and Strength (Sarcopenia): Strength and endurance decline with age due to a decrease in the size and quantity of muscle fibres. Daily functioning and movement are impacted by this.
2. Reduced Cardiovascular Efficiency: Blood arteries lose their elasticity and the heart's ability to pump blood decreases. Reduced stamina, slower circulation, and diminished aerobic capacity result from this.
3. Decrease in Bone Density: Minerals like calcium are lost from bones, making them weaker and more brittle. This raises the risk of osteoporosis and fractures.
