What is the body made of in percentages?
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.
Which 3 elements make up 10% or more of the total weight of the human body?
Many elements make up the human body, but only three occur in abundance. These elements, oxygen, carbon, and hydrogen, combine to form the constituents of some of the most essential processes in the human body, such as cellular respiration.
What are the 10 most abundant elements in the human body?
Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus are the most abundant elements found in the human body, followed by potassium, sulfur, sodium, chlorine, and magnesium.
What makes up the highest percentage of a human’s body weight?
In terms of tissue composition, bone, adipose tissue, and muscle make up 75% of body weight. The lean body mass is the mass of the body minus the fat mass (storage lipid).
What are the 10 most common elements in the universe?
- 1.) Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, ~70% of the Universe remains hydrogen.
- 2.) Helium. About 28% is helium, with 25% formed in the Big Bang and 3% from stellar fusion.
- 3.) Oxygen.
- 4.) Carbon.

What makes up about 15 percent of our body weight?
And In muscular males, bones make up 15% of the total body weight, muscles about 40 to 45% and fat about 15%. For both the sexes, the reminder of weight is a result of other matter including skin, connective tissues, tendons, Ligaments, blood plasma, organs, hairs and its related glands etc.
How many chemical elements make up the human body?
Elements in the Human Body . Six elements account for 99% of the mass of the human body. The acronym CHNOPS may be used to help remember the six key chemical elements that are used in biological molecules. C is carbon, H is hydrogen, N is nitrogen, O is oxygen, P is phosphorus, and S is sulfur.
Which is the most abundant chemical compound in the human body?
Organic compounds include fat, protein, carbohydrates, and nucleic acids. Water: Water is the most abundant chemical compound in living human cells, accounting for 65 percent to 90 percent of each cell. It’s also present between cells.
What makes up 96% of human body weight?
The elements – Oxygen, Carbon, Hydrogen and Nitrogen account for 96.2% of your body weight.
What is the percentage of water in the human body?
In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent, and these numbers along with the complementary % numbers for oxygen in water,…
