🔬Your body is made up of millions of cells that work together with specific functions.
🧩Organ systems do not work in isolation but function together as a team.
💡The circulatory system transports blood, which carries oxygen, nutrients, and removes waste.
🍽️The digestive system breaks down and absorbs food to provide nutrients for the body.
🧠The nervous system coordinates and controls voluntary and involuntary actions.
How are the systems in our body connected?
—The systems in our body are interconnected and work together to ensure the proper functioning of our body. For example, the circulatory system supplies oxygen and nutrients to other systems, while the respiratory system provides oxygen for the circulatory system.
What happens when one of the systems is not functioning properly?
—When one of the systems in our body is not functioning properly, it can disrupt the balance and functioning of other systems. This can lead to various health issues and symptoms.
What role does DNA play in our cells?
—DNA contains the genetic instructions that determine the structure and function of our cells. Each cell carries the entire DNA code, but different cells use specific parts of the code based on their function.
How does the digestive system break down food?
—The digestive system uses enzymes and acid to break down food into smaller molecules that can be absorbed by the body. This process starts in the mouth and continues in the stomach and small intestine.
What is the largest organ in the human body?
—The skin is the largest organ in the human body. It helps protect our organs, regulate body temperature, and prevent water loss.
