what percentage of the human body is phosphorus?
441297
In humans, phosphorus makes up about 1 to 1.4% of fat-free mass. Of this amount, 85% is in bones and teeth, and the other 15% is distributed throughout the blood and soft tissues [1]. Many different types of foods contain phosphorus, mainly in the form of phosphates and phosphate esters [1].

Phosphorus (P) is the element with the atomic number 15.

Phosphorus works with calcium and vitamin D in your body to keep your bones healthy and strong.To do this, your body's phosphorus, calcium and vitamin D all need to be in balance. When you have too much phosphorus in your blood, it causes your body to pull calcium from your bones to try and keep your blood balanced.

Bone weight depends on how much a person”s entire body weighs. Bones make up around 15% of a person”s total body weight. While people do have different frame size, most who weigh too much for their height do so because of excess body fat.

So 41.66% percent of proteins of the human body is equivalent to the weight of its skin.

The result is that about 45% of the mass of the human body is due to neutrons, 55% is protons (0.027% is electrons). An average human weights around 80 kg, so there are 36 kg of neutrons. Each neutron weighs 1.675 E-27 kg. So there are 36/1.675 E-27 = 2.15 E28 neutrons in a human body.

The amount of phosphate in the blood affects the level of calcium in the blood. Calcium and phosphate in the body react in opposite ways: as blood calcium levels rise, phosphate levels fall. A hormone called parathyroid hormone (PTH) regulates the levels of calcium and phosphorus in your blood.

In a fit female, bones make up 12% of the total body weight, muscles about 30 to 35% and fat around 27%. And In muscular males, bones make up 15% of the total body weight, muscles about 40 to 45% and fat about 15%.

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. The remaining 4 percent is a sparse sampling of the periodic table of elements.
456913
Total body water is 60% of body weight (40% intracellular and 20% extracellular). Plasma (blood) volume is 5% of body weight.

“The human body is made up of a long list of 'ingredients', with the most abundant being oxygen (65% by mass), carbon (18%), hydrogen (10%), nitrogen (3%), calcium (1.4%) and phosphorous (1.1%),” Elisabeth Ratcliffe, of the Royal Society of Chemistry (RSC) wrote in an email.

Protein and minerals account for 15% and 5% of body composition, respectively. The 1018 cells forming the cellular body composition domain can be divided into connective tissue cells (fat cells, blood cells, and bone cells), epithelial cells, neural cells, and muscle cells.

As you can see in the pie graph at the left, about 97 percent of your body's mass consists of just four major elements— oxygen, carbon, hydrogen, and nitrogen. The six most common elements in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.

According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%. Each day humans must consume a certain amount of water to survive.

Bone content is the percentage of bone mineral as compared to total body weight. The average bone content for adults is 3-5%. This measurement is good to keep track over a long period of time as bone mass can decline slowly with age.

More than half of your body is not human, say scientists. Human cells make up only 43% of the body's total cell count. The rest are microscopic colonists.

By mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent). These elements do not give color to fireworks, but they are found in our body's most abundant and important molecules, including water, proteins and DNA.
