Connective Tissue A&P1

What is Connective Tissue?

• connects body parts

• composed of cells and extracellular matrix (ground substance and fibers)

What are the 3 fibers in Connective Tissue?

• collagen - strength

• reticular - support

• elastic - for stretch and recoil

What is Loose Fibrous CT?

• type of CT

• surrounds, cushions, and supports organs

• combines with epithelial tissue to form membranes

What is Areolar Tissue?

• type of Loose CT

• surrounds organs and subcutaneous

• has the different fibers in its matrix

What is Reticular Tissue?

• type of Loose CT

• supports liver, spleen, and lymph nodes

What is Adipose Tissue?

• type of Loose CT

• surrounds heart, kidneys

• subcutaneous skin

• has fat cells, energy storage and cushion organs

What is Adipose Tissue?

• type of Loose CT

• surrounds heart, kidneys

• subcutaneous skin

• has fat cells, energy storage and cushion organs

What is Dense Regular CT?

• fibers are arranged orderly

• found in tendons (bone to muscle) and ligaments (bone to bone)

What is Dense Irregular CT?

• has no pattern, goes in different directions

• found in dermis of skin

What is Cartilage Tissue?

• type of CT

• covers ends of bones (joints) , forms ears and nose

• has 3 types

• made of chondrocytes (widely spaced cells)

What is Hyaline Cartilage?

• creates smooth surfaces for joint movement

• most abundant and weakest

What is Fibro Cartilage?

• shock absorption, strength and rigidity

• found in pubic symphysis and intervertebral discs (btw vertebrae)

What is Elastic Cartilage?

• strength and elasticity

• external ear and tip of nose

What is Bone Tissue?

• type of CT

• composed of osseous tissue

• 2 types

What is Compact Bone Tissue?

• bone hardness

• osteon system

What is Spongy Bone Tissue?

• has spaces, not dense

• no osteons

Blood

• type of CT

• transports O2, nutrients, hormones, and removes waste

Erythrocytes

• red blood cells

• transport O2

Leukocytes

• white blood cells

• for immunity, fights infections

Thrombocytes

• platelets

• cellular fragments that aid in blood clotting

Lymph

• type of CT

• fluid that flows in lymphatic vessels

• involved in immunity
