Elemental Composition of the Human Body Oxygen is the most abundant element in the earth's crust and in the body. The body's 43 kilograms of oxygen is found mostly as a component of water, which makes up 70% … of total body weight. Oxygen is also an integral component of all proteins, nucleic acids (DNA and RNA), carbohydrates, and fats.

What Are the 3 Most Common Elements in Human Bodies? Oxygen is the most abundant element in the human body. It makes up 65 percent of the total weight of a person. For a person with a weight of 155, about 94 pounds of her total weight would be made of the element oxygen. This is due mainly to the body's water content.

Composition of the human body The average 70 kg (150 lb) adult human body contains approximately 7027700000000000000♠7×1027 atoms and contains at least detectable traces of 60 chemical elements. About 29 of these elements are thought to play an active positive role in life and health in humans.

Abundance of the chemical elements Abundance of the chemical elements. By mass, human cells consist of 65–90% water (H2O), and a significant portion of the remainder is composed of carbon-containing organic molecules. Oxygen therefore contributes a majority of a human body's mass, followed by carbon. Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. The next 0.75% is made up of the next five elements: potassium, sulfur, chlorine, sodium, and magnesium.

What Are the 3 Most Common Elements in Human Bodies? Hydrogen is the most abundant element in the universe, and is also the smallest element. It makes up about 9 percent of the total weight of the human body. A person who weighs 170 pounds gets about 15 pounds of that weight from hydrogen. Two hydrogen atoms are present in every water molecule.

Elemental Composition of the Human Body Vanadium is the body's least abundant element (0.11 mg) that has a known biologic role, followed by cobalt (3 mg), the latter being a constituent of vitamin B12. Oxygen is the most abundant element in the earth's crust and in the body. The body's 43 kilograms of oxygen is found mostly as a component of water, which makes up 70% of total body weight.

Chemical Composition of the Human Body Oxygen is the most abundant element in the human body accounting for approximately 65% of a person's mass. Each water molecule consists of two hydrogen atoms bonded to one oxygen atom, but the mass of each oxygen atom is much higher than the combined mass of the hydrogen.

Elements in the Human Body 65%. Oxygen. This element is obviously the most important element in the human body. Oxygen atoms are present in water, which is the compound most common in the body, and other compounds that make up tissues. It is also found in the blood and lungs due to respiration. 18.6%. Carbon.

Elemental Composition of the Human Body By mass, oxygen is the most abundant element in the human body. If you think about it, this makes sense, since most of the body consists of water or H 2 O. Oxygen accounts for 61-65% of the mass of the human body.arbon is the second most abundant element in the human body, accounting for 18% of body weight. All organic molecules (fats, proteins, carbohydrates, nucleic acids) contain carbon.

What are the four most common elements in living things? Report Abuse. Hydrogen, Oxygen, Carbon, Nitrogen The hydrogen and oxygen are in the water that makes up most of our bodies. The carbon is what they mean when they say carbon based life forms. The nitrogen is also very common in organic molecules.

The Four Elements Over the past two centuries, we have gained a much better understanding of the atomic elements and how they have formed. One of the things we have learned is that we—and every other living thing on Earth—are made up mostly of four elements. These four atomic elements are oxygen, carbon, hydrogen, and nitrogen. Together they make up about 96% of our bodies, as you can see in the figure.

The Four Elements The atoms in your body contain the history of the universe. The hydrogen in your body was born among the first elements, about 13.7 billion years ago. The carbon, nitrogen and oxygen in your muscles and mind were created within a star that died more than 5 billion years ago. You are the universe made manifest.

Questions and Answers Ok, here it goes. Hydrogen, oxygen and carbon make up about 99% of the average human. I'm going to cheat a little and leave out the other 1%, which is made up of trace elements (that is, stuff there's only a trace of in the body).Then, let's assume an average adult weighs 70 kilograms.k, here it goes.

Hyperthermia In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. Hyperthermia requires an elevation from the temperature that would otherwise be expected. Such elevations range from mild to extreme; body temperatures above 40 °C (104 °F) can be life-threatening.

The most common element in the universe is? exists and is an alternate of . Hydrogen is the most common element in the universe as a whole; about 75% of the universe by mass is hydrogen (since hydrogen is also the lightest element, that means that the percentage by number of atoms is even higher) . Helium is second; oxygen is a fairly distant third.

- Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
