What is epithelial cells normal range?

What is epithelial cells normal range?

WBCs, RBCs, epithelial cells, and, rarely, tumor cells are the cellular elements found in the urinary sediment. The number of WBCs considered normal is typically 2-5 WBCs/hpf or less. A high number of WBCs indicates infection, inflammation, or contamination.

What are the functions of epithelial tissue?

Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.

What is the main function of connective tissue?

Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. Connective tissues can have various levels of vascularity. Cartilage is avascular, while dense connective tissue is poorly vascularized.

How would you describe epithelial tissue?

Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

What are the 5 main types of connective tissue?

What are the five different types of special connective tissues? What are the five main connective tissue characteristics? small, banded collagen; reticular CT (CT of organs), smooth muscle, endoneurium, blood vessels, lung, lymphoid tissues, bone marrow, and fetal skin.

What is an example of a connective tissue?

Steve Gschmeissner/Science Photo Library/Getty Images. Specialized connective tissues include a number of different tissues with specialized cells and unique ground substances. Some of these tissues are solid and strong, while others are fluid and flexible. Examples include adipose, cartilage, bone, blood, and lymph.

What are the 4 functions of epithelial tissue?

In general, four functions may be attributed to epithelial tissues: (1) protection of the underlying tissues, (2) absorption, (3) secretion, and (4) reception of sensory stimuli.

What are 3 types of connective tissue?

Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers.

What are three general characteristics of connective tissue?

Structural elements of connective tissue: Connective tissues consist of three parts: cells suspended in a ground substance or matrix; and most have fibers running through it. Ground substance is a clear, colorless, viscous fluid that fills the space between the cells and fibers.

What are the connective tissue?

The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants—bone, ligaments, tendons, cartilage, and adipose (fat) tissue. Connective tissue.

What type of tissue is skin?

There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart. Our outer layer of skin is epithelial tissue.

What is a tissue in science?

Tissue Definition. Tissues are groups of cells that have a similar structure and act together to perform a specific function. … There are four different types of tissues in animals: connective, muscle, nervous, and epithelial.

What is a tissue in biology?

In biology, tissue is a cellular organisational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

What organelles are in epithelial cells?

Answer and Explanation: Epithelial cells have six organelles in each cell, with specialized cells having additional organelles. The six common organelles are the nucleus,…

What are the 6 types of epithelial tissue?

There are six major types of connective tissue, including loose connective tissue, dense connective tissue, bone, cartilage, blood and lymph.

Is blood a tissue?

Blood is considered a connective tissue because it has a matrix. … Blood Tissue: Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers. Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide.
