The most abundant chemical substance in the human body is water. There are a lot of H2O molecules throughout the human body.
The second most abundant substance in the human body is proteins. Proteins are essential for various functions in the body, including building and repairing tissues, supporting the immune system, and serving as enzymes and hormones.
Water is the most abundant substance in the human body, making up approximately 60% of our total body weight.
Water is the most abundant substance in the human body, making up about 60% of an adult's body weight. It plays a crucial role in many bodily functions, including temperature regulation, nutrient transport, and waste removal.
Proteins are the second most abundant substance in the human body and are essential for the structure, function, and regulation of all cells. They play a critical role in various biological processes such as growth, repair, and immunity.
Neither - a human is not a physical or chemical change. A human is a type of living multicellular organism.A physical change is a process where the actual molecules and atoms of a substance do not change, but appearance will change.A chemical change is a process where the actual molecules and atoms of a substance change, usually along with the appearance.
This substance is water, H2O.
Water is the single most abundant chemical substance in the body, making up about 60% of an adult's total body weight.
The second most abundant substance in the human body is proteins. Proteins are essential for various functions in the body, including building and repairing tissues, supporting the immune system, and serving as enzymes and hormones.
Water is the most abundant substance in the human body, making up approximately 60% of our total body weight.
H2O or water!
Water is the most common molecular subsance found in the human body(~98%). and phosphorous is the most abundant element in human body.
carbon

The question is flawed. Substance can mean element or molecule. I'll go with molecule since organic simply means carbon atoms are present. Hydrogen dioxide is the most abundant inorganic "substance".
Protein.
According to Marieb, 8th edition, "Electrolytes are the most abundant solutes in body fluids and determine most of their chemical and physical reactions"
