Chapter 5 Tissue Test Flashcards
What is a tissue?
A tissue is an organized group of similar cells with a common function.
What is histology?
The study of tissues
General function of Epithelial Tissue
The general function of epithelial tissue is to cover and protect other tissues. It lines body cavities and hollow organs.
General characteristic of Epithelial Tissue
The cells are packed tightly together with very little intercellular matrix.
What are the 3 shapes of Epithelial tissues?
Squamous, cuboidal, and columnar
Location and function of squamous tissue
Found at sites of diffusion and filtration. Line the air sacs of the lungs, forms the walls of capillaries, and lines the inside of vessels.
Location and function of cuboidal tissue
Found in kidney tubes, covers ovaries, and ducts of certain glands. Function is secretion, absorption, and protection.
Location and function of columnar tissue
Found in female reproductive tract, uterus, and portions of the digestive tract. Functions are protection, excretion secretion, and absorption
How do the proteins Collagen and Elastin differ in function?
Protein collagen helps with strength whereas protein elastin helps with elasticity.
What are the general characteristics/functions of connective tissues?
The general function of connective tissue is to bind other tissues together. The cells are loosely bound together and spread apart with extracellular material.
What is the unique function of adipose tissue?
Adipose tissue is unique because it stores fat.
How do cartilage and bone differ?
Bone has a good vascular system.
What are the major components of blood?
The major components of blood are red blood cells, plasma, and platelets.
What are the general characteristics/functions of muscular tissue?
The general function of muscle tissue is contraction. Composed of elongated cells that can shorten and thicken. Tissue is highly cellular and well supplied with blood vessels.
What are the three types of muscular tissue? How are they alike? How are they different?
The 3 types of muscle tissue are skeletal, smooth, and cardiac. Skeletal and cardiac are striated. Smooth muscle is not. Skeletal muscle is voluntary; cardiac and smooth are involuntary. All composed of the same elastic fibers.
