Circulatory system – order of blood flow through the heart; Step by step Pathway of Blood Flow Through the Heart; Quick and easy to learn in 14 steps
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.
Does being alone at home make a person go insane? After weeks of social distancing because of COVID-19, people locked up in their homes may be getting bored and restless. Attending school, going out to eat, hanging out with friends — parts of their lives that are normal — are no longer possible. What is the science behind the human’s social brain, and what does isolation do to the brain?
In this easy optics physics lesson, we learn about differences between Concave and Convex Lens, the Thin Lens Equation and how to problem-solve AP Physics or MCAT Physics problems.
In this lesson, we will explain the differences between the upper and lower respiratory system and the differences between upper respiratory tract infections and lower respiratory tract infections.
What are the differences between the left lung and right lung? Here, we detail quick and easy to learn summary points of the right lung vs left lung. Left vs Right Lung
What is the respiratory system? In general, the respiratory system is a biological system that contains organs and structures that assist in gas exchange. Gas exchange involves the movement of carbon dioxide and oxygen between our circulating blood and air. In this educational lesson, we explore seven general functions of our respiratory system.
While our famous British wizard Newt Scamander arrived in New York City in 1926 with a suitcase of magical beasts and fantastic creatures, many of our friends from the roaring 1920s donned the most popular spectacles style and historical vintage prescription glasses during that time: the round […]
