Blood comprises red blood cells carrying oxygen, white blood cells fighting infections, and platelets aiding in clotting to stop bleeding. Its liquid part, plasma, transports nutrients, waste, and hormones throughout the body. Red blood cells deliver oxygen to tissues, white blood cells defend against germs, platelets prevent excessive bleeding, and plasma carries essential substances, ensuring the body functions properly by supporting immunity, oxygenation, and healing.
Blood is vital for the body as it performs several essential tasks. It delivers oxygen to all body cells, providing energy for daily activities. Nutrients like sugars and proteins are carried by blood from the digestive system to nourish organs and tissues, supporting growth and repair. Blood also cRead more
Blood is vital for the body as it performs several essential tasks. It delivers oxygen to all body cells, providing energy for daily activities. Nutrients like sugars and proteins are carried by blood from the digestive system to nourish organs and tissues, supporting growth and repair. Blood also collects waste products from cells, like carbon dioxide, and transports them to be expelled from the body. White blood cells in blood fight off germs, keeping the body healthy. Additionally, blood carries hormones that help regulate body functions. Its role in oxygenation, nourishment, waste removal, immunity, and hormonal balance is crucial for maintaining a healthy body.
Blood looks red due to red blood cells (RBCs) containing a molecule called hemoglobin. Hemoglobin carries oxygen, binding with it to form oxyhemoglobin, giving blood its bright red color. When RBCs release oxygen in tissues, it forms deoxyhemoglobin, making blood appear darker red or bluish in veinsRead more
Blood looks red due to red blood cells (RBCs) containing a molecule called hemoglobin. Hemoglobin carries oxygen, binding with it to form oxyhemoglobin, giving blood its bright red color. When RBCs release oxygen in tissues, it forms deoxyhemoglobin, making blood appear darker red or bluish in veins. The red hue varies based on oxygen levels: oxygen-rich blood appears bright red, while oxygen-poor blood looks darker. Hemoglobin’s role in carrying oxygen gives blood its distinct red color.
The heart acts as a vital pump in the body's circulatory system. It pumps oxygen-rich blood to all parts of the body through arteries and receives oxygen-depleted blood back from the body, sending it to the lungs for re-oxygenation. This continuous circulation delivers oxygen and nutrients to organsRead more

It pumps oxygen-rich blood to all parts of the body through arteries and receives oxygen-depleted blood back from the body, sending it to the lungs for re-oxygenation. This continuous circulation delivers oxygen and nutrients to organs and tissues while removing waste products. By regulating blood flow and pressure, the heart ensures proper distribution of essential substances throughout the body, supporting overall health and bodily functions.
Excreting waste products is essential for the body's health. When cells work, they produce waste like carbon dioxide and urea. If not removed, these wastes can harm the body. Excretion maintains a balance inside the body, preventing toxic build-up. It helps regulate temperature by sweating and suppoRead more

Excretion maintains a balance inside the body, preventing toxic build-up. It helps regulate temperature by sweating and supports organ function. Organs like the kidneys remove waste from the blood, ensuring the body works well. Overall, excretion keeps the body healthy by removing harmful substances and maintaining balance.
