Bodily Fluids

Bodily fluids, also known as biofluids, are liquids within the human body that perform various functions. These fluids include, but are not limited to, blood, urine, saliva, sweat, semen, breast milk, and cerebrospinal fluid. Each of these fluids plays a crucial role in maintaining the body's overall health and functionality.

Blood[edit | edit source]

Blood is a specialized bodily fluid that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. It is composed of blood cells suspended in blood plasma.

Urine[edit | edit source]

Urine is a liquid by-product of metabolism in humans. Its primary function is the excretion of waste products such as urea and uric acid, dissolved in water.

Saliva[edit | edit source]

Saliva is a clear liquid that's made by several glands in your mouth area. It helps in the early phase of digestion, lubrication, and protection of the oral mucosa.

Sweat[edit | edit source]

Sweat is a clear, salty liquid produced by glands in your skin. It helps to regulate body temperature by cooling the body through evaporation.

Semen[edit | edit source]

Semen is a white or grey liquid, emitted from the male reproductive tract, that contains sperm and fluids (semen plasma) which help the sperm to travel and survive.

Breast Milk[edit | edit source]

Breast milk is the milk produced by the breasts (or mammary glands) of a human female for her infant offspring. It provides the primary source of nutrition for newborns before they are able to eat and digest other foods.

Cerebrospinal Fluid[edit | edit source]

Cerebrospinal fluid is a clear, colorless body fluid found in the brain and spinal cord. It provides cushioning for the brain, among other functions.
