What are exocrine glands and how do they function?

Exocrine glands release substances via ducts onto epithelial surfaces, such as skin and mucous membranes.

What are some examples of exocrine glands?

Examples include sweat glands, salivary glands, and mammary glands.

What are the functions of exocrine glands?

Functions include cooling through sweat, lubrication via mucus, and enzymatic digestion through saliva.

What is tissue damage?

Tissue damage is injury or harm to body tissues caused by trauma, infection, or inflammation.

How does the body respond to tissue damage?

The body reacts through inflammation, immune responses, and repair processes.

What can chronic tissue damage lead to?

Chronic tissue damage can result in fibrosis or necrosis.

What defines the role of different tissue cells?

Tissues consist of specific types of cells that perform distinct roles.

What is the role of epithelial cells?

Epithelial cells serve as protective barriers.

What is the function of connective tissue cells?

Connective tissue cells provide support.

What is the primary function of muscle cells?

Muscle cells are responsible for movement.

What is the role of nerve cells in tissues?

Nerve cells facilitate signal transmission.

Why is cell structure and function important in tissues?

Cell structure and function are vital to the overall function of tissues.

What is fibrosis?

Fibrosis is the thickening or scarring of tissue, often due to chronic inflammation or injury.

What is necrosis?

Necrosis is the death of cells or tissues due to disease, injury, or inadequate blood supply.

What is the extracellular matrix (ECM)?

The ECM is a network of proteins and carbohydrates that surrounds, supports, and gives structure to cells and tissues.

What are common components of the ECM?

Collagen, elastin, fibronectin, and laminin are key components of the ECM.

How does the ECM contribute to tissue function?

The ECM regulates cell behavior, provides structural support, and influences tissue development and repair.

What are the four main types of tissue?

Epithelial tissue, connective tissue, muscle tissue, and nervous tissue are the four main types.

What is the function of the basement membrane?

The basement membrane supports epithelial tissue and separates it from underlying connective tissue.

What are the different types of muscle tissue?

Skeletal muscle, smooth muscle, and cardiac muscle are the three types of muscle tissue.

What is the role of glial cells in nervous tissue?

Glial cells support and protect neurons in nervous tissue.

How do tissues work together to form organs?

Different tissues combine to form organs, each performing specific functions that contribute to the organ's overall role.
