The two spherical surfaces in a lens are part of spheres, and their centres are known as centres of curvature (C1 and C2). These centres play a crucial role in defining the optical properties of the lens.
Lymphatic capillaries collect tissue fluid or lymph from intercellular spaces, and larger lymph vessels drain into veins. This process helps regulate fluid balance by returning excess fluid from the extracellular space back into the blood, ensuring efficient circulation.
Lymph or tissue fluid is formed when plasma, proteins, and blood cells escape through capillary walls into intercellular spaces. It serves as a colorless fluid similar to blood plasma, with fewer proteins. Lymph drains excess fluid and carries digested fats ...
Platelet cells circulate in the blood to plug leaks in the circulatory system, helping to clot blood at points of injury. This response minimizes blood loss and maintains the efficiency of the pumping system.
