Quick Summary for Revision: Circulatory System and Excretory System
The Circulatory System
1. What is the Circulatory System?
- The circulatory system is like a delivery system in our body. It moves blood, oxygen, and nutrients to every part of the body.
2. Main Parts of the Circulatory System:
- The Heart: A muscular pump that pushes blood throughout the body.
- Blood: The fluid that carries oxygen, nutrients, and waste.
- Red blood cells: Carry oxygen.
- White blood cells: Fight germs.
- Platelets: Help in clotting.
- Blood Vessels: Tubes that carry blood.
- Arteries: Carry blood away from the heart.
- Veins: Carry blood to the heart.
- Capillaries: Tiny vessels that connect arteries and veins.
3. How Does Blood Flow in the Body?
- Blood flows in a loop: heart → body → heart → lungs → heart.
4. Heartbeat and Pulse:
- The heartbeat is the sound of the heart pumping blood.
- The pulse is the throbbing you feel when blood flows through your arteries.
5. Why is the Circulatory System Important?
- It supplies oxygen and nutrients.
- Removes waste products like carbon dioxide.
6. Tips to Keep Your Circulatory System Healthy:
- Eat healthy foods like fruits and vegetables.
- Exercise regularly.
- Avoid smoking and too much junk food.
The Excretory System: Keeping Our Bodies Clean and Healthy
1. What is Excretion?
- Excretion is the process of removing waste products from the body.
2. Organs Involved in the Excretory Process:
- Kidneys: Filter blood to remove waste and extra water.
- Lungs: Remove carbon dioxide.
- Skin: Removes waste through sweat.
- Liver: Breaks down toxins.
3. How Do the Kidneys Work?
- The kidneys filter blood to remove waste. The waste combines with water to form urine.
4. The Urinary System:
- Includes kidneys, ureters (tubes carrying urine to the bladder), bladder (stores urine), and urethra (releases urine).
5. The Journey of Waste in the Body:
- Blood carries waste → kidneys filter it → urine forms → bladder stores urine → urine exits through the urethra.
6. Why is the Excretory System Important?
- It removes harmful waste.
- Keeps the body clean and balanced.
7. Fun Facts About the Excretory System:
- Kidneys filter about 50 gallons of blood daily!
- Sweating helps cool your body and removes small amounts of waste.
8. Taking Care of the Excretory System:
- Drink plenty of water.
- Eat foods rich in fiber.
- Avoid too much salt and sugary drinks.
