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

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

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

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

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

6 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

7 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

8 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)

9 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

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

11 -Mast cells – that produce histamine and dilate blood vessels

12 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

13 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

14 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

15 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

16 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

17 Connective tissue is involved with the immune response

18 Mast cell tumor in dog

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

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

21 White Blood Cells!

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

23 Abdominal Fat

24 Adipose Connective Tissue
