Liquid body substances refer to the various fluids found inside the human body that serve crucial functions for maintaining overall health and facilitating bodily processes. These substances include blood, lymph, saliva, tears, urine, semen, gastric juices, cerebrospinal fluid, and various other bodily fluids.
Blood is a vital liquid in the body, responsible for transporting oxygen, nutrients, and hormones to different tissues and organs, as well as removing waste products. Lymph is a clear fluid that circulates through the lymphatic system, aiding in the immune response and collecting waste materials from the body's tissues. Saliva, produced by salivary glands, helps in digestion by breaking down food particles and moisturizing the mouth. Tears moisten and protect the eyes from foreign particles, while urine eliminates waste products from the body through the urinary system. Semen contains sperm cells and aids in fertilization during sexual reproduction.
Other liquid body substances, such as gastric juices, help in the digestion process by breaking down food in the stomach. Cerebrospinal fluid surrounds the brain and spinal cord, providing protection and nutrients. These various liquid substances work together to maintain homeostasis, eliminate waste, fight infections, and ensure the proper functioning of the different systems within the human body.
