To top it up I also read about particle physics (particle physics research is focused on subatomic particles such as electrons, protons, and neutrons (protons and neutrons are actually composite particles, made up of quarks) and to stir up the plot further we had Quantum Mechanics (the branch of quantum physics that accounts for matter at the atomic level) with its sci-fi theories -string theory,multi-verse, parallel universe, anti-matter et al.
And so it was with tremendous courage I set about to put this myriad concepts into one narrative. Using resources from the internet, have provided the appropriate credit & acknowledgement . So here is my attempt to connect Human Anatomy to the Atomic Theory
The cell is the functional basic unit of life. It was discovered by Robert Hooke and is the functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life.Some organisms, such as most bacteria, are unicellular (consist of a single cell). Other organisms, such as humans, are multicellular.
Humans have about 100 trillion cells; a typical cell size is 10 µm and a typical cell mass is 1 nanogram. The largest cells are about 135 µm in the anterior horn in the spinal cord while granule cells in the cerebellum, the smallest, can be some 4 µm and the longest cell can reach from the toe to the lower brain stem (Pseudounipolar cells) . Althought there are different types of cells, most cells have the same components. A cell consists of a nucleus and cytoplasm and is contained within the cell membrane, which regulates what passes in and out. The nucleus contains chromosomes, which are the cell's genetic material, and a nucleolus, which produces ribosomes. Ribosomes produce proteins, which are packaged by the Golgi apparatus so that they can leave the cell. The Cytoplasm consists of a fluid material and organelles, which could be considered the cell's organs. The endoplasmic reticulum transports materials within the cell. Mitochondria generate energy for the cell's activities. Lysosomes contain enzymes that can break down particles entering the cell. Centrioles participate in cell division.
Related cells joined together are collectively referred to as a tissue. The cells in a tissue are not identical, but they work together to accomplish specific functions.The body's functions are conducted by organs. Each organ is a recognizable structure—for example, the heart, lungs, liver, eyes, and stomach—that performs specific functions. An organ is made of several types of tissue and therefore several types of cells. For example, the heart contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats. The eye contains muscle cells that open and close the pupil, clear cells that make up the lens and cornea, cells that produce the fluid within the eye, cells that sense light, and nerve cells that conduct impulses to the brain http://www.merck.com/mmhe/sec01/ch001/ch001b.html
Now we will approach the human body at a atomic level, the average 70 kilogram adult contains about 67 Octillion ( followed by 27 zeroes) atoms and is composed of 60 chemical elements.
Out of which 98.5 % comprises of 6 elements in terms of Mass ( Oxygen - 65, Carbon-18, Hydrogen - 10, Nitrogen - 3 , Calcium - 1.5 and Phosphorous -1)For the entire list of 60 elements and their proportion in the body refer the link
This is the estimated composition in terms of the chemical break up of compounds in one cell
Water - 65 % ( Hydrogen & Oxygen)
Other Inorganics - 1.5 %(ions like sodium, potassium, chloride, bicarbonate, phosphate)
Lipids - 12 %
Other Organics - 0.4 % -Carbohydrates such as glycogen and glucose
Protein - 20 %
RNA -1.0 %
DNA - 0.1 %
Hair - hair fiber is keratin. Keratins are proteins, long chains (polymers) of amino acids
Muscles - made of fibres. Each fibre is made up of long thin cells which are packed in bundles. The fibres have two kinds of protein, myosin and actin
Bones - Organic material a protein called Collagen and Inorganic -calcium phosphate / carbonated hydroxyapatite.
So atoms of various elements (Oxygen, Carbon, Nitrogen etc) make up the compounds (Proteins, Fats, Inorganic compounds, Water) that help create the various types of cells that builds various organs that make up the Human Anatomy... atoms to anatomy ..
And inspite of the fact that no two humans look and usually (think) alike but at a cellular level we all have the same 100 trillion cells and at an atomic level consits of 67 octillion atoms of oxygen, carbon, nitrogen, hydrogen, calcium, phosphorous etc. In Conclusion I can state "Though we would like to consider each one of ourselves as unique & different but at an atomic level we are all the same" !!
And the force of attraction between two humans is similar to the force of attraction that keeps the atoms in our body attached together in an molecule --- Chemistry !!!
