The liver is a vital organ in the human body that processes nutrients, detoxifies harmful substances, and produces essential proteins for blood clotting and digestion.​

An ecosystem is a community of living organisms—such as plants, animals, and microbes—interacting with each other and with the non-living elements of their environment, including air, water, soil, minerals, sunlight, and climate. These interactions form complex relationships and result in the cycling of nutrients and the flow of energy, supporting life within the ecosystem.​

🧬 What are enzymes?Enzymes are special proteins that speed up chemical reactions in living things. They are like tiny biological machines inside your body.

⚡ How they work:

• Enzymes work on specific substances called substrates.

• The substrate fits into the enzyme like a key fits into a lock — this is called the lock-and-key model.

• The enzyme helps the reaction happen faster, then stays unchanged so it can be used again.

Examples:

I learned about kidneys.

1. when we eat food and water, all the nutrients go to the blood cells.

2. All the nutrients will be absorbed from the small intestine.

3. The intestine will leave little nutrients outside.

4. All the nutrients and water will go to the kidneys, it become urine and go to the urinary bladder.
