Top 7 Biology Infographics

Biology is fascinating and interesting. It has the potential to improve human life and health and also can help us understand many other aspects of living things.

The Digestive System

Digestion can start long before a person begins eating. Just the sight, smell or thought of food can start the digestive process. The mouth produces between .5 to 1.5 liters of saliva on a daily basis. The saliva prepares the food for digestion and this occurs while chewing. The chewed food goes down the esophagus and makes its way into the stomach. Here gastric acid acts on the food to break it down still further. In the small intestine nutrients are absorbed, while the large intestine absorbs any remaining water and nutrients from the food. And what remains is sent to the colon for elimination out of the body via the anus.

Understanding the Biology of a Hangover

When a person consumes alcohol, the pituitary gland in the brain prevents the manufacture of vasopressin. This causes water in the body to go straight to the bladder rather than getting absorbed by the body. As a result, a person tends to expel more water than he would do when not drinking alcohol. The following morning, this causes the mouth to feel dry and the headache occurs as the body tries to meet its water needs by taking water from the brain. This causes the brain membrane to be pulled, leading to the famous hangover headache.

Understanding Photosynthesis

Plants need sunlight, carbon dioxide, water and chlorophyll for photosynthesis. During the process of photosynthesis, plants create sugar, which is then sent to the rest of the plant as food and oxygen is a byproduct, which is released into the atmosphere.

The Human DNA

The full form of DNA is deoxyribonucleic acid. The DNA was first isolated in 1869 by a scientist named Friedrich Miescher. However, he called his discovery nuclein and not DNA. DNA has a double helix structure and is composed of amino acid. The entire DNA sequence is referred to as a genome and it contains 3,000,000,000 DNA bases. Did you know that 99.9 percent of our DNA is the same as other people? Or, humans and chimpanzees share between 94 to 99 percent of their DNA?

Bioprinting – Printing the Human Body

Bioprinting makes use of cells, hydrogel and a bioprinter. This allows tissue to be printed which can be used for research and for testing new drugs. It is believed that in the future, bioprinting may help in therapies and finding out the causes of certain diseases. It is possible that in the future bioprinting could help with tissue and organ transplant too.

Why Raw Milk is Better Than Pasteurized Milk?

Raw milk does not contain antibiotics or hormones. People suffering from lactose intolerance can drink raw milk without worries. Plus, raw milk has high CLA levels, active enzymes, is hypoallergenic and contains beneficial living bacteria. On the other hand, pasteurized milk no CLA, contains hormones, which can increase the chances of cancer, is hyperallergenic, causes lactose intolerance and contains antibiotics, which causes harmful bacteria to proliferate.

Benefits of Cloning

Stem cells can help treat blood diseases, such as leukemia and lymphoma; studying how stems cells develop into other types of cells will allow scientists find out more about certain health conditions, like disease and birth defects; stem cells can be used for testing new drugs and medications; and stem cells can be used to replaced damaged heart tissue in people suffering from heart disease. Presently, stem cells are used for bone marrow transplants and skin grafting in people with burns.
