How can I keep my kidneys healthy?

Do you remember the scene in Finding Nemo where the fish jam up their aquarium filter to get their dentist owner to clean the tank? That scene always makes me think of kidneys – because without them, our bodies would become rapidly overloaded with waste products, just like that dirty aquarium water! Most of us…...

Is it true that the spleen has no specific function?

The spleen has been the target of much ridicule, made fun of by medical students and dismissed as nothing more than a "graveyard for red blood cells."

What is the lymphatic system?

What is the lymphatic system?

Just as most people don't know much about their spleens, they also know very little about their lymphatic system. Perhaps it's no surprise that the two are related? Both the spleen and the lymphatic system (with its vessels and nodes) play an important role in our immune response to disease and infections. Not to…...

What is anemia?

What is anemia?

The term "anemia" is quite broad, and simply means that there is a problem with a person's red blood cells (sometimes there are too few, sometimes they are malformed). Red blood cells are manufactured in the bone marrow and are basically tiny sacks of oxygen-carrying hemoglobin molecules (centered around an iron atom) that circulate through…...
