Phosphorus Part 2: Health Risks and Disadvantages. Part 1 of this article described the uses and advantages of the element phosphorus. However, there are also various health risks that come with using phosphorus in our lives.
Vitamins and minerals both help our bodies work properly, and they aid with functions such as growth and development. So what is the difference between the two? Simply stated, vitamins are organic and minerals are inorganic. This means that vitamins come from living sources, like plants and animals, while minerals come from elsewhere, such as the earth. Vitamins tend to have more complex structures than minerals, and because of this, are more prone to degradation via heat or chemicals. Today, we will be focusing on vitamins.
The muscular system allows us to move and do our daily tasks. It also provides heat, stability, and blood flow for our body. There are three main types of muscular tissue: cardiac muscle, which comprises the heart muscle, smooth muscle, which comprises the linings of organs, and skeletal muscle, which are the muscles that help our body move. This article will focus on the physiology of skeletal muscles.

The COVID-19 pandemic has people across the world self-quarantining, but what does that mean for the furry additions of our families? Are animals affected by the virus like we are?
You can probably find that phosphorus is the 15th chemical element if you look at a periodic table. You might also easily guess that it has the chemical symbol P. But what you may not know is that beyond these basics, there are many different applications of phosphorus that make it a significant part of our everyday lives.
Come learn about interesting factors about phosphorus with us!
Polar bears, Siberian tigers, our friendly neighborhood bees – what do they all have in common? That’s right. They’re all endangered species!

In March 2020, U.S. President Donald Trump touted hydroxychloroquine as an effective treatment for coronavirus disease 2019 (COVID-19). Mr. Trump highlighted the drug cocktail of hydroxychloroquine and azithromycin as “one of the biggest game changers in the history of medicine.”1 But how effective is hydroxychloroquine in combating COVID-19 in actuality?
In this article, we learn about hydroxychloroquine a potential drug treatment for COVID-19 and evaluate its scientific efficacy.
Help, I smell like fish! Is this even possible?
Body odor is a fact of life. For many, this is a simple fix either through some deodorant or a quick shower, but for some unlucky few, a fishy odor always remain. This is none other than Fish Odor Syndrome, a rare genetic disorder also known as Trimethylaminuria (TMAU). Learn more about the biology behind Fish Odor Syndrome, the FMO3 gene, cures and treatments.

Pneumothorax also known as collapsed lung occurs when air is trapped in the pleural space. Trapped air causes a loss of negative pressure in the pleural cavity, reduces surface tension, and induces the lungs to collapse. There are 3 types of Pneumothorax or collapsed lungs: 1) Spontaneous 2) Traumatic, and 3) Tension Pneumothorax.
In this lesson, we learn the different types of pneumothorax (collapsed lung) and important terminology. USMLE
