👉 Animal fluids, such as blood and lymph, play crucial roles in maintaining the health and proper functioning of an organism. Blood, a vital fluid, transports oxygen, nutrients, hormones, and waste products throughout the body via its circulatory system, while also participating in immune responses and temperature regulation. Lymph, another essential fluid, circulates through the lymphatic system, where it helps filter out pathogens and cellular debris, aiding in immune defense. Both fluids are critical for sustaining life, ensuring that cells receive necessary substances and waste is efficiently removed.
