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...
The organs such as the brain, skin, liver and kidneys have specific functions in the body. Organs are made up of tissues: tissues that are supportive and tissues carry out specific functions. These tissues in turn are made up of cells, of which...
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...
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....
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...
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...
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...
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...
The cell is the most basic unit of life. The body is composed of 200 different types of cells, each sustaining a specific role to maintain life. Each cell is comprised of similar components; for example, each cell is enveloped by a plasma...
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...
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...
If you think of cookies, cakes and ice cream at the mention of carbohydrates, you may think this food group is all bad for your health; however, carbohydrates are one of the major nutrients that your body can not do without. Carbohydrates are...
Blood is a major biological product produced by your body that is essential to human life. Blood contains a variety of cellular and non-cellular components. Red blood cells are the primary method used by the body to exchange oxygen for carbon...
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...
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...
Like other blood cells, white blood cells are produced by the bone marrow. White blood cells are far less numerous than red blood cells as there are about 700 red blood cells to every white blood cell in circulation. The biological roles of white...
The kidneys are essential organs responsible for blood filtration. Each kidney consists of an outer cortex rich in blood vessels and an inner medulla. Both the cortex and the medulla contain millions of nephrons, the functional units of the kidney...
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...
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...
Vitamin B-12 is an essential vitamin in maintaining nerve cell function, red blood cell function, and in maintaining genetic material, states the MayoClinic website. Vitamin B-12 is a water-soluble vitamin excreted in the urine when the body's...
Aging skin suffers from a gradual loss of nutrients. Exposure to the skin can dry out your skin and take vitamins and other nutrients that can hinder your skin's shimmer and elasticity. The key to healthy skin is keeping it well-hydrated, and...
Some herbs have the ability to influence immune system function. They work by suppressing T cells, which when functioning normally, protect the body from infection. However, the immune system can become imbalanced and lead to excessive...
Vitamin B12 is a water-soluble vitamin that is important in metabolism, red blood cell function and nervous system function, according to Medline Plus. Folic acid acid is used to prevent anemia and is instrumental in preventing birth defects and...
Red blood cells, also called erythrocytes, play an important role in maintaining your health and supporting day-to-day activities. Specialized proteins on the surface of red blood cells -- such as hemoglobin and myoglobin -- bind oxygen in your...
According to the National Institutes of Health, vitamin B12 is a water soluble vitamin necessary for human body function. Functions include healthy nerve cell function, red blood cell function and DNA synthesis. Vitamin B12 is absorbed by the...
Idebenone is a synthetic version of ubiquinone, (coenzyme Q10) which the body makes naturally in cholesterol regulation. Mayo Clinic staff say the natural counterpart is part of normal cell function. Since levels in your body decrease with age,...
Cellulite can plague both men and women on areas like the abdomen, arms and thighs. Fat deposits that rest underneath the skin's surface cause the orange peel or dimpling appearance. Coenzyme Q10 is produced by the body to aid cell function....
The pancreas, which secretes digestive enzymes and the hormone insulin, is classified as an accessory digestive organ. Your pancreas is a long, tail-shaped organ situated between your liver and the upper portion of your small intestine. A variety...
