Bacteria cells function quite differently from human cells, from the function of the cell as a whole, right down to the individual structures in each cell. Bacteria exist in nature as individual cells. While some bacteria work together in a group,...
Muscles are a fibrous group of tissues that provide contraction, allowing the body to move. Muscles also function in many vital biological processes including the contraction of the heart, the movement of food through the digestive system and the...
Cells are the biological units of life, and all living organisms are composed of one or more cells. Some organisms, like bacteria, are made up of a single cell responsible for all the functions performed by the organism. More complicated living...
The heart functions as the motor of the circulatory system, which consists of the heart, blood vessels and blood. The heart pumps approximately 2,000 gallons of blood through the body each and every day, according to the American Heart...
Paramecium are a genus of organisms within the kingdom Protista, which represents single cell organisms and some multicellular algae. While the organisms in the more familiar plant and animal kingdoms are composed of many cells that work together...
Computers, like human cells, perform many functions. In some cases, functions of a computer overlap slightly with functions of a human cell, while in other cases, there are significant differences between the functions that the two perform....
The immune system is a complex network of cells, tissues and organs working together to defend the body against foreign invaders. The workhorse cells of the immune system are the white blood cells (WBC). They consist of both specific and...
The Immunology Department of Western Kentucky University reports on Bioweb that the body produces more than 5 million B cells every day that enter the bloodstream and lymphatic system. B cells perform the role of immune surveillance and...
Cells are the basic unit of life. Humans are multi-celled complex organisms that require each part to work together. Every organ and system of the body depends on each cell to perform three major functions. These functions are vital to the life of...
Epithelial cells are specialized cells which line many different kinds of tissue. Columnar epithelial cells are named because they are somewhat rectangular in shape and resemble a column in their orientation. Columnar epithelial cells are often...
Contrary to popular opinion, fat cells in adipose tissue are not simply dormant storage depots, according to Johns Hopkins Medicine Health Alerts. Fat cells are dynamic and highly active. The fat cells of adipose tissue share an extremely...

Simple squamous epithelium consists of a single layer of thin cells that are often flattened. These cells have a variety of functions within the body and are primarily used to line certain tissues. These cells are used to make very thin linings...
Peroxisomes are oval, sac-like organelles that exist in many cells in the body but are most abundant in the liver cells, or hepatocytes. These microscopic cellular structures are so named because they generate hydrogen peroxide in detoxification...
Electrolytes are charged minerals such as sodium, potassium, calcium, phosphate and magnesium that are vitally important for the body. Cells maintain an electrical potential; they are negatively charged relative to their surroundings. Signals can...
The human digestive system is a complicated group of organs that extracts the nutrient molecules from food, so that they can be absorbed by the bloodstream and become available to cells for energy. The functions of the digestive system are both...
The human body holds more than 100 trillion cells, according to the National Institute of Child Health and Human Development. Human cells are small, too tiny to be seen without using a microscope, but they make up all of the organs and systems of...
Cantron is an electrolyte and antioxidant supplement made by Medical Research Products. It is an advanced version of Entelev, which was invented by James Vincent Sheridan. The company claims Cantron contributes to health benefits such as...
