"Test preparation material (mostly explanatory videos) for nursing students preparing for the National Council Licensing Examination for Registered Nurses (NCLEX-RN).

Circulatory system
Learn about how the heart pumps blood throughout the body. Find out how blood vessels are organized. Understand how blood gets oxygen to the tissues, and then how it gets back to the lungs to absorb more oxygen.

Cardiovascular system diseases
With the heart pumping 24 hours a day, 7 days a week, it’s absolutely vital to make sure things are flowing smoothly (pun intended!). Unfortunately, this isn’t always the case, and different parts of the circulatory system can cause problems: your heart, your blood vessels, and even the fluid in your tissues and blood itself can be the issue. To further complicate things, the underlying reasons for circulatory system problems vary from your genes (nature) to your lifestyle habits (nurture). An understanding of how different diseases can affect your circulatory system is important to combat this growing problem in the world.

Respiratory system
Our lungs are composed of a bronchial tree (think of an upside down tree with millions of leaves), blood vessels bringing blood in and out, and a protein-rich fluid that forms a matrix holding everything together! If any part of this well-balanced organ isn’t working properly, a person can be left feeling short of breath. The lungs are also exposed to the outside environment, making them prone to infections. To counter infections, the lungs are lined with cells that have tiny protein bristles which wave back and forth and can literally sweep away dangerous bacteria. Learn more about diseases of the lungs and how modern medicine helps to keep them healthy!

Hematologic system diseases
Blood is incredibly important in combating disease and the healing process after an injury. It acts as a highway for medicine, stops bleeding, fights infections, controls cells from multiplying too fast, and so much more. But things can go wrong with blood too! What if your blood couldn’t clot and stop you from bleeding, or started to clot uncontrollably? What if your red blood cells or white blood cells suddenly disappeared? Blood contains many different types of tissues doing very different jobs, making diseases of the blood produce a variety of symptoms, including continuously feeling tired and bone pain. Learn about the different blood diseases, how they are diagnosed, and the cool ways health professionals treat these conditions.

Endocrine system
Dive into the endocrine system! See how the body uses special organs (called glands) that secrete chemical messages (called hormones) in order to properly respond to it's changing environment.

Lymphatic system
Welcome to the lymphatic system! Learn about how it is a critical part of the circulatory system. Find out how it comes to the rescue of the cardiovascular system and the immune system. Also discover how it moves fluid in one direction, like blood, but without a heart!

Immune system
Discover your body's arsenal of weapons against invaders, like bacteria and viruses. Find out which different kinds of cells are involved, and how they work.

Renal system
Learn how the kidneys take blood and very selectively extract waste from it to expel from the body as urine. Learn how the kidneys vary our salt and water content to regulate our blood pressure.

Gastrointestinal system
Understand how we digest food from the second it enters our mouth to the moment it ends up in the bathroom. Learn how the Gastrointestinal Tract is perfectly designed to digest food and extract nutrients for our bodies to use.

Muscular system
How do our muscles work? When we decide to kick a ball or shake a leg, how do we get our bodies to do that? Which muscles do we control? Which muscles control us? Learn how our muscles work at the smallest, most cellular level. Then see how nature scales up those microscopic processes into a kick or a dance move. Finally, learn how our brain tells muscle to contract and how that helps us respond to changes in temperature or even a lion chasing us.

Skeletal system
The skeletal system plays numerous vital roles in the human body. Learn about the structure and function of bones and the skeleton, as well as the endocrine control of the skeletal system."
