Connective Tissue

Connective Tissue The most abundant and widely diverse of all the basic tissue types

Connective Tissue Connective tissue has a wide variety of functions including:

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together - Support and strengthens other tissues

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together - Support and strengthens other tissues - Protects and insulates internal organs

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together - Support and strengthens other tissues - Protects and insulates internal organs - Compartmentalizes structures

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together - Support and strengthens other tissues - Protects and insulates internal organs - Compartmentalizes structures - Transport system for blood

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together - Support and strengthens other tissues - Protects and insulates internal organs - Compartmentalizes structures - Transport system for blood - Stores energy (fat or adipose tissue)

Connective Tissue Connective tissue has a wide variety of functions including: - Binding tissue together - Support and strengthens other tissues - Protects and insulates internal organs - Compartmentalizes structures - Transport system for blood - Stores energy (fat or adipose tissue)

- Immune system responses

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”
