Thehumanbody uses amino acids to build proteins, which are used to control the processes that take place in cells. Proteins also accelerate chemical reactions inthe body, making them necessary for survival. Although the body uses 20 amino acids, it only produces some of them on its own.
Learn the importance of acid base balance inthehumanbody. Everything from what you eat to how you breathe plays a role. Learn how to help your
Your body uses the amino acid arginine to make nitric oxide. Nitric oxide helps lower blood pressure by relaxing muscles in your blood vessels. It's produced in heart muscles, where it regulates contractions. It may also prevent atherosclerosis by inhibiting the development of plaque in your arteries.
Fatty acids are important components of thehumanbody, having biological, structural and functional roles. Besides their role as source of energy, they act as main constituents of cellular membranes. In this case, as part of the membrane phospholipids, they assure the fluidity, flexibility, permeability of...
The most important acids to thehumanbody are amino acids, fatty acids, ascorbic acid and hydrochloric acid.
The buffer systems inthehumanbody are extremely efficient, and different systems work at different rates. It takes only seconds for the chemical buffers inthe

The pH of thehumanbody lies in a tight range between 7.35-7.45, and any minor alterations from this range can have severe implications.
What citric acid effect to humanbody? Taking citric acid and sodium citrate can have side effects. Serious effects include cramps or muscle twitching
Humanbody is evolutionary capable to handle acid load. _ Systems responsible for maintenance of the acid-base balance.
In this way, we are faced with a substance which thehumanbody creates when decomposing a substance known as purine. Most of the uric acid is dissolved inthe blood and travels to the kidneys, where it is eliminated through urine, making this chemical not in itself problematic.
Uric acid is a naturally-occurring waste product produced by the body. Humans are not very good at getting rid of uric acid, and in some people it builds up and causes a form of joint pain (usually toe pain) called gout. ...
Carbohydrates are present inthehumanbody largely as fuels, either as simple sugars circulating through the bloodstream or as glycogen, a storage compound
Inthe stomach cavity, the hydrochloric acid changes the pepsinogen into an active digestive enzyme called pepsin. This enzyme digests proteins.
DNA contains the blueprint of the organisms in a double helix molecule. Its subunits are called nucleotides and they in turn, consist of a sugar called
Thehumanbody is everything that makes up, well, you. Many complex processes go on inside the body, some of which you may not think about in
Lactic acid is naturally present in humans, as well as in animals. It is well known that it is formed from glycogen by muscle cells when the oxygen supply is
Uric acid is formed inthebody from the normal breakdown of chemicals called purines, which develop from normal DNA and RNA turnover, from
That means the liver inthehumanbody refers to approximately 16,000 distinct lobules. If you do a little more math
Immersed inthe heart of the university and hospital practice, you’ll learn from professors, health professionals, interns and medical students.
The increase in carbonic acidinthe blood stimulates the lungs to expel more CO2, which eventually causes the acidinthe blood to be lowered back to a normal range.
There are different kinds of proteins found inthehumanbody and each of these proteins has specific functions to do.
Describe the hybridization state of the C and N atoms, and determine the number of sigma amd pi bonds inthe molecule.
Thehumanbody can make most of the types of fats it needs from other fats or raw materials. That isn’t the case for omega-3 fatty acids (also called omega-3 fats and n-3 fats). These are essential fats—the body can’t make them from scratch but must get them from food.
The most important function of hydrogen inthehumanbody is to keep you hydrated.
is the sum of all the chemical processes that occur inthebody.
“The amount of blood inthehumanbody depends on a number of factors, including body size, age, sex, health status and sometimes there region where they live.” Indeed, people living in high altitudes tend to have more blood than their counterparts in lower altitudes. This is because of the air, wherein...
Thehumanbody as an integrated whole is a highly dynamic system maintaining its form and function even as individual cells are routinely dismantled and
Humanbody systems summary. The heart powers the circulatory system, pumping blood through the body to supply all cells with food and oxygen and to remove wastes. The muscles and bones work together to support and move the body using energy from respiration of this food and oxygen.
What's the strongest muscle inthebody? What's the tiniest human cell? These questions and many other bizarre quandaries will be answered in this
Why is body weight expressed in kilograms? Because the metric system is very clever: One liter of fluid weighs one kilogram.
Chemical contaminants in your body. Some of the chemicals residing in our bodies are pesticides, and some are used in or produced by other forms of industrial production. Many are found in a wide variety of consumer products. Some chemicals like dioxins and furans are created unintentionally by...
Include in your answer at least one type of macromolecule from each of the following three categories: Carbohydrates, Lipids, Nucleic Acids.
For many of you, the semester will be ending inthe next week or two. Can you see the light at the end of the tunnel? The time is almost here when you
In addition to the reproductive, digestive, cardiovascular, respiratory and nervous systems are the less well known lymphatic system, which helps protect the body against pathogens
Landmarks on the body are areas where the bone is at the surface. The landmarks are used to find forms and to measure proportion.
Ernst Mayr, who won the prize in 1994, was honored for his work in systemic biology and taxonomy. Born in Germany in 1904, Mayr came to the U.S. to work in a curatorial position at the American Museum of Natural History. He joined Harvard’s faculty in 1953.
Tissue inthehumanbody: Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces. A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.
Macro-molecules are incredibly important to thehumanbody. They are composed of a large number of atoms. Every single cell inthe body is made up of
The organs in your respiratory system work together to take in oxygen from the air and remove carbon dioxide from your body. Air enters and exits through your nose and mouth. Mucus and small hairs called cillia in your nasal cavity help stop harmful things from entering your lungs.
The most obvious organs inthehumanbody are those that are visible on the outside. Getting a sense of human anatomy usually requires a look at what’s going on inside, either through surgery or diagnostic imaging, but this isn’t the case with those parts that sit externally, either in part or in full.
The authors of the study found that the 10:1 ratio of bacterial to human cells goes back to a 1977 study by Dwayne Savage and an earlier 1972 paper
