Digestion – the process of breaking down food into smaller molecules to be absorbed and utilized by the body.

Respiration – the process of inhaling oxygen and exhaling carbon dioxide, necessary for cellular respiration and energy production.

Circulation – the process of blood flow through the body, which transports oxygen, nutrients, and hormones to the cells.

Impact of the Human Body

The human body has a profound impact on our daily lives, affecting various aspects such as:

Health and Wellness – understanding the structure and functions of the human body can help us make informed decisions about our health and wellness, such as exercising and eating a balanced diet.

Medicine – advancements in medical science have led to the development of new treatments and cures for diseases, improving the quality of life and longevity of individuals.
