🚰 HUMAN EXCRETORY SYSTEM

The Human Excretory System is responsible for removing metabolic waste products, excess water, and toxins from the body, helping maintain internal balance and overall health.

🩺 Major Components:

✅ Kidneys – Filter blood and produce urine.

✅ Ureters – Transport urine from the kidneys to the urinary bladder.

✅ Urinary Bladder – Stores urine temporarily.

✅ Urethra – Carries urine from the bladder to the outside of the body.

🔄 Urine Formation Process:
1️⃣ Blood enters the kidneys.
2️⃣ Waste products and excess water are filtered.
3️⃣ Urine passes through the ureters.
4️⃣ Urine is stored in the bladder.
5️⃣ Urine is expelled through the urethra.

📌 Did You Know?
The kidneys filter approximately 180 liters of fluid daily, but only about 1–2 liters are excreted as urine.

💡 Tips for Healthy Kidneys:
✔ Stay well hydrated
✔ Limit excessive salt intake
✔ Control blood pressure and diabetes
✔ Get regular health check-ups

❤️ HUMAN CIRCULATORY SYSTEM

The circulatory system is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body. It consists of the heart, blood vessels, and blood.

🫀 Main Components:

✅ Heart – The muscular pump that drives blood circulation.

✅ Arteries – Carry oxygen-rich blood away from the heart.

✅ Veins – Return oxygen-poor blood back to the heart.

✅ Capillaries – Tiny vessels where the exchange of oxygen, nutrients, and waste occurs.

🔄 Blood Circulation Pathway:
1️⃣ Deoxygenated blood returns to the heart.
2️⃣ The heart pumps it to the lungs.
3️⃣ Blood receives oxygen in the lungs.
4️⃣ Oxygenated blood returns to the heart.
5️⃣ The heart pumps it throughout the body.

📌 Did You Know?
The average adult has about 5 liters of blood, and the heart beats approximately 100,000 times each day.
