Connective Tissues have a variety of different cells in their tissues including:

Connective Tissues have a variety of different cells in their tissues including: Mast cells – that produce histamine and dilate blood vessels

Connective Tissues have a variety of different cells in their tissues including: Mast cells – that produce histamine and dilate blood vessels Fibroblasts – large, flat cells, the most numerous of CT cells that serve as part of the extracellular matrix

Connective Tissues have a variety of different cells in their tissues including: Mast cells – that produce histamine and dilate blood vessels Fibroblasts – large, flat cells, the most numerous of CT cells that serve as part of the extracellular matrix Plasma cells – secrete antibodies

Connective Tissues have a variety of different cells in their tissues including: Mast cells – that produce histamine and dilate blood vessels Fibroblasts – large, flat cells, the most numerous of CT cells that serve as part of the extracellular matrix Plasma cells – secrete antibodies Macrophages – engulf bacteria and other cellular debris

Connective Tissues have a variety of different cells in their tissues including: Mast cells – that produce histamine and dilate blood vessels Fibroblasts – large, flat cells, the most numerous of CT cells that serve as part of the extracellular matrix Plasma cells – secrete antibodies Macrophages – engulf bacteria and other cellular debris Adipocytes – fat cells that store triglycerides

Connective Tissues have a variety of different cells in their tissues including: Mast cells – that produce histamine and dilate blood vessels Fibroblasts – large, flat cells, the most numerous of CT cells that serve as part of the extracellular matrix Plasma cells – secrete antibodies Macrophages – engulf bacteria and other cellular debris Adipocytes – fat cells that store triglycerides White blood cells (leukocytes) – migrate from the blood into the connective tissue during immune responses

Connective tissue is involved with the immune response

Mast cell tumor in dog

Human fibroblast cells - these cells contain numerous different types of proteins which can be visualized with different stains

Phagocytosis of red blood cells Macrophages – Macrophages can consume objects through the process of phagocytosis many times their own size

White Blood Cells!

Real white blood cells also known As “leukocytes” Red blood cells, aka “erythrocytes”
