The hemolymph in the gill forms a chamber and a system of reserve capillaries extending into the inner surface of the chamber. Reservation of hemolymph also occurs in the system of openings, which look like sieve alveoli, to the surface of the branchial arch. All this serves to maintain a constant blood composition and ensure simultaneous absorption of nutrients. If damaged by hemorrhage, the gills die, which leads to death! Most hemolymphophore cells have a diameter of about 5–6 μm, divided by a thin transparent constriction into two halves, each of which contains a cell center and a neuroectodermal inclusion. Many of these cells form a layer around the hemolymphatic droplets and are spherical or pyramidal in shape. The total number of hemolymphoid cells is about 30-38%. Hemolymphocytes also include red blood cells. The number of red blood cells in the hemolymph depends on the presence of tissue fluid. Adding tissue fluid to the hemolymph increases the number of red blood cells.
