![]() ![]() ![]() ![]() Total body water in healthy adults is approximately 60% (range 45-75%) of total body weight women and obese people tend to have a lower percentage than thin men. Extracellular fluid (ECF) refers to all fluids of the body external to the cells of any multicellular organism. Lymph is extracellular as the fluid is traveled outside the cell but not inside the cells. The meaning of Extracellular outside the cells. Note: Lymph is a fluid formed by the immune system that consists of white blood cells that fight off infectious substances that have moved into the body. Extracellular fluid: - It refers to the fluid outside the cells, which includes interstitial fluid (between the cells) and plasma (the liquid component of blood). Extracellular fluid and Intracellular fluid’. After entering the lymphatic vessels, it is known as lymph. As new tissue fluid is produced, it replaces the old fluid that drains in the lymphatic vessels. Helps transport oxygen and nutrients to cells and remove wastes from them. It comes from substances that leak from the blood capillaries (the smallest type of blood vessel). See Figure 15.1 1 for an illustration of intracellular and extracellular compartments. In fact, intracellular fluid accounts for 60. Intracellular fluids are crucial to the body’s functioning. The most abundant electrolyte in intracellular fluid is potassium. Intracellular fluids (ICF) are found inside cells and are made up of protein, water, electrolytes, and solutes. Body fluids are found in two main areas of the body called intracellular and extracellular compartments. Figure 15.1 Intracellular and Extracellular Compartments. The main constituent of ECF is the intravascular fluid in the circulatory system called plasma of the blood.Īdditional information: Fluid found in the spaces around cells. Body fluids consist of water, electrolytes, blood plasma and component cells, proteins, and other soluble particles called solutes. The main constituent of extracellular fluid is the interstitial fluid that surrounds the cells of the body. Interstitial fluid is the fluid that fills the intercellular spaces. The main constituent of fluid outer to the cell is the interstitial fluid that surrounds the cell externally. Hint: Presence of water, amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, and cellular products in the case of the interstitial fluid. ![]()
