Unit 4 Biology: Lymph and Muscle Tissues

Vocabulary flashcards covering the characteristics, components, and functions of Lymph and Muscle tissues as described in the Unit 4 Biology lecture notes.

Lymph (Fluid Connective Tissue)

A fluid contained in lymphatic vessels consisting of a clear or faintly yellow matrix and white blood cells.

Matrix (lymph)

A clear or faintly yellow fluid derived from tissue fluids.

White Blood Cells

Cells that congregate in lymph nodes and lymphatic organs or tissues.

Reticular Connective Tissue

The type of tissue that composes lymphatic organs and tissues where white blood cells congregate.

Functions of Lymphatic Vessels

Absorb excess tissue fluid and dissolved solutes for transport to the cardiovascular system and absorb fat molecules from the small intestine.

Lacteal Vessel

A specific type of vessel that absorbs fat molecules from the small intestine.

Muscle Tissues

Tissues that allow for movement of the body and are composed of contractile cells called muscle fibers.

Muscle Fibers

Contractile cells that compose muscle tissue, each containing protein filaments known as actin and myosin.

Actin Filaments

One of the two types of protein filaments found within a muscle fiber that interacts to produce muscle contraction.

Myosin Filaments

One of the two types of protein filaments found within a muscle fiber that interacts with actin to produce muscle contraction.

Muscle Contraction

The process produced by the interaction between actin and myosin filaments.

Muscle Tissue Types

The three classifications of muscle tissue: Skeletal muscle, Cardiac muscle, and Smooth muscle.

Megakaryocyte and Platelets

Components listed in the notes as part of the fluid connective tissue section alongside lymph and white blood cells.
