How does age affect heart function?
Age profoundly influences heart function, leading to various changes in its structure and performance over time. As individuals age, the heart undergoes physiological alterations that can affect its efficiency and increase the risk of cardiovascular diseases. One significant change is a gradual decline in cardiac muscle mass and elasticity. With age, the heart muscle may […]
Difference between a heart attack and cardiac arrest?
A heart attack and cardiac arrest are two distinct medical emergencies involving the heart, but they have different causes, symptoms, and treatments.

What is the cardiac cycle?
The cardiac cycle refers to the sequence of events that occur during one complete heartbeat, encompassing the contraction (systole) and relaxation (diastole) of the heart chambers. It is a vital process that allows the heart to pump blood efficiently throughout the body, providing oxygen and nutrients to tissues while removing waste products. The cardiac cycle […]
Purpose of the heart valves?
Heart valves play a crucial role in the circulatory system by ensuring that blood flows in the correct direction through the heart chambers. The heart consists of four chambers: two atria (upper chambers) and two ventricles (lower chambers). The valves are located between these chambers and function as one-way gates, allowing blood to flow forward […]
