hemocyte

Hemocytes are cells found in the blood of many invertebrates, playing a crucial role in the immune system and other physiological processes. These cells, which originate from the embryonic mesoderm, are involved in engulfing foreign particles and pathogens through a process called phagocytosis.12

Key functions of hemocytes include:
* Immunity: Phagocytic hemocytes ingest and destroy foreign invaders like bacteria and parasites, providing a defense against infection. Some hemocytes can also encapsulate larger parasites that cannot be engulfed.12
* Wound Healing: Certain hemocytes contribute to closing wounds by trapping other cells to seal lesions until tissue regeneration occurs.1
* Connective Tissue Formation: Some hemocytes are involved in forming connective tissue and secreting substances for basement membrane formation.1

In addition to these roles, hemocytes can also be involved in intermediate metabolism. In some invertebrates, hemocytes are the primary means of transporting oxygen, especially when dissolved oxygen in plasma is insufficient.1
