- Blood is a fluid connective tissue that circulates throughout the body, carrying oxygen, nutrients, hormones, and waste products. It consists of red and white blood cells, plasma, and platelets.
- Plasma is the liquid component of blood and makes up about 55% of total blood volume. It carries nutrients, hormones, proteins, and waste products. Plasma also plays a crucial role in maintaining blood pressure and regulating body temperature.
- Lymph is a clear fluid that circulates lymphatic fluid through the lymphatic system. It collects waste materials, pathogens, and foreign substances from the body tissues and transports them to the lymph nodes for filtration and immune response.
- Cerebrospinal fluid (CSF) is a clear fluid that surrounds the brain and spinal cord. It acts as a cushion, protecting the central nervous system from trauma. CSF also helps supply nutrients and remove metabolic waste from the brain.
- Synovial fluid is found in the joints, providing lubrication and cushioning to facilitate smooth movement. It nourishes the joint cartilage and helps reduce friction between the bones. There are various types of synovial fluid, including normal, inflammatory, infectious, hemorrhagic, serous, fibrinous, and suppurative.
- Saliva is a watery fluid produced by the salivary glands in the mouth. It aids in digestion by moistening food, breaking down starches, and initiating the digestive process.
- Tears are fluid secretions of the lacrimal glands that help keep the eyes lubricated and protected. They contain substances that fight against bacterial infections and help wash away foreign particles.
- Sweat is produced by sweat glands located throughout the body and plays a role in regulating body temperature. It helps cool the body through evaporation and also eliminates certain waste products.
