Getting the air to our lungs in the first place can be challenging enough. How do we get the oxygen out of the air once we have it in our lungs? This huge job comes down to one tiny unit: the alveoli-capillary unit. In this brick, we take a look at how the exchange of…

The ovaries are a pair of reproductive organs located deep in the pelvis of the female body; they contain the female gametes, the ova.

The central nervous system (CNS) comprising the brain and spinal cord is an incredibly complex part of the human body, so it is no surprise that sometimes things go awry during development.

A neoplasm is the abnormal growth of new cells, sometimes called a tumor. A variety of tumors can grow in our bones, and luckily more of them are benign (noncancerous) than malignant (cancerous). What causes these tumors? We usually don’t know, though we do know that most malignant bone tumors are secondary, with cancer spreading…

Signs of Upper and Lower Motor Neuron Lesions
/

Every movement we make is caused by the contraction of different muscles, which are themselves controlled by the neurons that innervate them. However, one long nerve fiber does not run from the brain all the way down the spinal cord to reach our muscles. Instead, our bodies use a two-neuron system. After listening to this…

Bile is a greenish-yellow fluid produced by the liver. It is stored in the gallbladder and released into the small intestine, where it aids digestion by breaking down fats into fatty acids. Water is the main component of bile (about 95%). Bile also contains bile salts (the salt form of bile acids), cholesterol, phospholipids, bilirubin…

Brain Energy Metabolism
/

For the most part, the brain relies on glucose as its main energy source. In fact, we say the brain preferentially uses glucose. In times of low glucose levels such as fasting or starvation, the brain can use ketones, lactate, and amino acids (worth noting: the brain does not use fatty acids to generate energy).…

Before we jump into the details of essential thrombocythemia (ET), let’s back up for a little perspective. ET is one of a group of disorders called chronic myeloproliferative disorders. These disorders share a lot of similarities: they occur in adults, they have a relatively good prognosis, and they’re caused by mutations in proteins involved in…
