Cell Analogy to the Human Body
Transcript of Cell Analogy to the Human Body
By: Omar Ibrahim
Nucleus and the Brain
The nucleus is like the human brain because the nucleus stores the material (DNA and RNA) that guides the other organelles and the brain gives orders on what the human organs are supposed to do. The material in the nucleus controls the cell's actions and the brain controls the actions of a human
Nuclear Envelope and the Cranium
The nuclear envelope is like the human cranium because the nuclear envelope restricts passage into the nucleus and separates the nucleus from the cytoplasm, and the cranium restricts passage into the brain and separates the brain from the rest of the body.
Rough Endoplasmic Reticulum and the Liver
The rough endoplasmic reticulum is like the human liver because the rough ER synthesizes proteins, and the liver produces many proteins essential for a human to survive.
Smooth Endoplasmic Reticulum and the Gall Bladder
The smooth endoplasmic reticulum is like the human gall bladder because the smooth ER synthesizes lipids, and the gall bladder excretes bile, which is a type of lipid called cholesterol that assists in the breakdown of lipids in digestion.
Mitochondrion and the Lungs
The mitochondrion is like the human lungs because the mitochondrion carries out cell respiration, and the lungs carry out human respiration.
Golgi Apparatus and the Small Intestine
The golgi apparatus is like the small intestine because the golgi apparatus processes, packages, and secretes modified cell products, and the small intestine processes food by absorbing all the nutrients of the food as it moves through the small intestine.
Ribosomes and the Pancreas
Ribosomes are like the human pancreas because ribosomes carry out protein synthesis, and the pancreas secretes enzymes, which are proteins that assist in speeding up reactions in the human body.
The Cell Membrane and Skin
The cell membrane is like skin because the cell membrane regulates what enters and exits the cell, and skin regulates what enters and exits a human.
Cilia and Peristalsis
Cilia is like peristalsis because ciliated cells assist in the transportation of certain things, like transporting mucus back up the throat from the lungs and moving an egg cell through the fallopian tube. Peristalsis is the constriction and relaxation of muscles causing them to move in a wave like pattern that moves food through the alimentary canal (digestive track). Cilia is like peristalsis because they both assist in transport.
Flagella and the Vertebrae
Flagella is like the human vertebrae because flagella assist in the movement of the cell, and the vertebrae allows humans to move.
Centrioles and Sperm
The centrioles are like sperm because they assist in cell division (reproduction), and sperm from male humans allow female eggs to be fertilized which enables humans to reproduce.
Cytoskeleton and the Skeletal System
The cytoskeleton is like the skeletal system of a human because the cytoskeleton maintains the shape of the cell and assists in cell movement, and the skeletal system maintains the shape of a human and allows humans to move.
Peroxisome and Bile
Peroxisome is like bile produced in the liver of a human because peroxisome breaks down fatty acids, and bile helps break down and absorb fats in the digestive system.
Lysosomes and the Spleen
Lysosomes are like the human spleen because lysosomes digest macromolecules and worn out/old cell parts, and the spleen acts as a filter and recycles old blood cells
Vacuoles and Blood
In animal cells, vacuoles are like human blood because vacuoles store substances and nutrients, and blood contains nutrients and oxygen and transports it to other organs. Blood also carries waste and takes it away from other organs.
