Triglycerides and Fat Cells

• Triglycerides: A type of fat that can be stored in adipose (fat) tissue.

  • Fat cells can be depleted and flattened out but are not lost unless through surgical procedures like liposuction.

  • Fat cells alternate between being large (full) and small (flattened).

  • When cells are flattened, they appear empty with visible matrix surrounding them.

Subcutaneous Fat

• Located below the hypodermis and can be found around organs and within breast tissue.

• Serves multiple functions:

  • Protects organs and surrounds them, acting as a source of energy.

  • Provides insulation, particularly important in cold climates.

  • Offers cushioning around bones, although distribution varies significantly across the body.

    • Example: Areas like elbow blades may lack excess fat for protection.

• Accumulation of fat in organs can occur, which can lead to potential health issues.

Insulation and Energy Storage

• Important for body temperature regulation and protecting vital organs.

• Fat acts as a filling material in the body's internal spaces, aiding the body's shape.

• Insulation helps maintain energy supply during times of limited nourishment.

Connective Tissue Framework

• The matrix of adipose tissue includes fibers and various cells that balance bodily functions:

  • Serves as an energy reserve, storing excess nutrients for later use.

  • Plays a role in defense against foreign invaders through immune responses.

Muscle Tissue and Blood Cells

• Muscle tissue located in the dermis area, characterized by cord-like structures.

• Distinction between red blood cells and white blood cells:

  • Red Blood Cells: Transport oxygen and remove carbon dioxide; primarily involved with nutrient transport.

  • White Blood Cells: Integral for immune system defenses, targeting foreign invaders in the bloodstream.

Cartilage and Bone Structure

• Types of cartilage:

  • Elastic Cartilage: Flexible type surrounding certain bones, serving as a precursor to bone formation.

  • Fibrocartilage: Found between vertebrae, providing support and structure.

• Each bone section contains a central canal housing nerves and blood vessels within the cartilage matrix.
