👉 Incoming fluid, often referred to as blood or other bodily fluids entering a vessel or organ, is characterized by its unique properties and functions. It typically enters through specific openings called capillaries or venules, depending on the organ's structure. These openings are equipped with delicate, permeable walls that allow for the exchange of substances such as oxygen, nutrients, and waste products between the fluid and the surrounding tissues. The fluid's composition can vary based on the organ's needs, but it generally consists of water, proteins, electrolytes, glucose, and various gases. This dynamic exchange is crucial for maintaining homeostasis and supporting cellular functions within the body.
