What percentage of a Human is Water and what percentage is Carbon?
About 75% of a human is water, and about 18% is carbon.
The basic building blocks of the body?
There are four main elements that make up the human body. They are Hydrogen, Oxygen, Nitrogen and Carbon. They, together, make up around 96% of the human body. We also have traces of other elements that aren't necessary for life but help out body in some way or another. They are such elements as Sodium and Iodine.
Which two elements make up three-fourths of the human body?
There is sixty percent water in your body. Water is made up of oxygen and hydrogen. There are double the number of hydrogen atoms or molecules as compared to oxygen in the water. But you have the mass of oxygen atom or molecule is 16 times more than that of hydrogen atom or the molecule. In case of water hydrogen to oxygen mass is one to eight, in proportion.
What organism in the human body absorbs carbon dioxide and releases oxygen?
There is no organism in the human body that absorbs CO2 and releases O2, CO2 is a waste product to us.
What is the atom that represents the greatest weight in the human body?
Short Answer:By weight, oxygen makes up approximately 65% of the human body.Numerically, hydrogen approaches 65% of the total number of atoms in the human body, but it is probably closer to 63% for most people.The compound that contributes most to the weight of a human is water which averages around 60% of the weight of an adult.Accounting by Mass:The mass of the human body is provided mostly by oxygen, carbon, hydrogen, nitrogen. Together these elements account for about 96% of the mass of a human.Add in about a kilogram of calcium in the bones and body fluids and you are up to 97.4%. All of this depends on the particular person since water, our major component, can differ by 10% from one individual to another.That said, typically the breakdown goes like this.Oxygen: 65% of the massCarbon: 18% of the massHydrogen: 10% of the massNitrogen: 3% of the massCalcium: 1.4 % of the massPhosphorus 1.1% of the massWith phosphorus, one has accounted for 98.5% of the mass of the typical human and that will change by a couple of tenths from person to person.Accounting by Numbers:Numerically we have nearly twice as many hydrogen atoms in our bodies as compared to all other elements combined. Specifically, hydrogen counts as 63% of our atoms by number, give or take a bit, but being so light it barely gets to 10% of our mass. Oxygen atoms count as 24% and carbon atoms are a mere 12% of the populations. Together, our three basic organic building blocks account for 99% of all the atoms in the body.Caveat:As was said above, the water content of the human body weight varieties between 55 to 65 % from one person to the next and being the major component changes the numbers above a little for each individual.Summary:Almost 99% of the mass of the human body is made up of the six elements oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.Most of the last 1% is made up of five elements: potassium, sulfur, sodium, chlorine, and magnesium, but a tenth of a percent or so is made up of another dozen or so elements which include those recognized as essential to health such as iron, iodine and fluorine as well as beneficial trace elements like manganese, copper and zinc.
What 4 elements make up the human tissue?
The four elements that make up the greatest percentage of the human body by percentage of body mass are oxygen (65%), carbon (18.5%), hydrogen (9.5%), and nitrogen (3.2%) but there are many others in smaller amounts.
What percentage of human hair is Carbon and Oxygen?
Human hair is approximately 45% carbon and 45% oxygen, making up the majority of its composition along with hydrogen. The remaining elements in hair include nitrogen, sulfur, and trace minerals like iron and zinc.
What four elements make up 96 percent of the human body?
The four elements that make up 96 percent of the human body are oxygen, carbon, hydrogen, and nitrogen. These elements are found in abundance in biological molecules such as water, proteins, carbohydrates, fats, and nucleic acids, which are essential for human life and function.
