Types of Tissues

The human body comprises four primary types of tissues, each with distinct functions and characteristics. Epithelial tissue is primarily involved in protection, secretion, and absorption.

Types of Tissues

Types of Tissues

Nervous Tissue

Nerve tissue
Found all over your body
Transmit Signals

Connective Tissue

Special Connective
Adipose

Cushions eyeball sockets - Kidneys

Protects and Insulates (stores energy)

Blood

Throughout body

Transport vehicle

Bone

Skeleton

Protect and Support

Cartilage

Larynx attaches ribs to breast bones

Supports structures and covers end of bones

Fibrous
Recticular

Lymphoid organs (spleen, bone marrow)

Framework of your lymphatic system

Elastic

Surrounding stomach, bladder, or intestines

Expands and Contracts

Dense

Ligaments and Tendons

Connect and Stretch (elasticate)

Loose Connective Tissue (aerolar)

Internal Organs (everywhere)

Cushions and Protects

Epithelial Tissue

Pseudostratified Columnar
Trachea (Lining air passage way)
Absorpition and Secretion - Cilia-aided movement
1 layer (looks like more)
Simple Columnar
Small Intestine (Digestive Tract)
1 layer (column)
Stratified Cuboidal
Salivary glands and Sweat glands
Protection and Secretion
Simple Cuboidal
Kidney Tubules
Secretion and Absorption
1 layer (cube)
Stratified Squamous
Lining of body cavities (Skin and Mouth)
Protection
More than 1 layer
Simple Squamous
Lungs and Blood Vessels
Diffusion and Filtration
1 layer (Flat)

Muscle Tissue

Cardiac Tissue
Heart
Pump and propels blood
Smooth Tissue
Digestive tract (Walls of hollow organs)
Helps food move through digestive tract (becomes smaller or enlarges)
Skeletal Tissue
Found everywhere in body
Movement (voluntary)
