Introduction: The Curious Case of Worms
Worms, with their elongated and seemingly simple bodies, have fascinated scientists and curious minds for centuries. Despite their seemingly primitive appearance, worms have managed to survive and thrive in a variety of environments, from soil to water. One of the most intriguing aspects of worms is the absence of a heart, a vital organ found in most animals, including humans.
Understanding the Heart’s Function in Animals
Before delving into the absence of hearts in worms, it is important to understand the function of this organ in animals. The heart is responsible for pumping blood throughout the body, delivering oxygen and nutrients to the cells and removing waste products. This process is essential for the survival of animals, as oxygen is needed for cellular respiration and energy production. The heart is also involved in regulating blood pressure and maintaining the balance of fluids in the body.
