Today Hank explains the skeletal system and why astronauts Scott Kelly and Mikhail Kornienko are out in space studying it. He talks about the anatomy of the skeletal system, including the flat, short, and irregular bones, and their individual arrangements of compact and spongy bone. He'll also cover the microanatomy of bones, particularly the osteons and their inner lamella. And finally, he will introduce the process of bone remodeling, which is carried out by crews of osteocytes, osteoblasts, and osteoclasts.

As we promised last week, we're not quite done talking about your pee yet. Today Hank explains how the urinary system regulates the production of urine, by maintaining a study glomerular flow rate. He'll also cover the anatomy of storing and excreting urine -- from the ureters to the urethra -- and the nervous systemโs role in controlling the act of urination.

In which Adriene Hill and Jacob Clifford teach you about one of the fundamental economic ideas, supply and demand. What is supply and demand? Well, youโll have to watch the video to really understand it, but itโs kind of important for everything economically. Supply and demand sets prices, and indicates to manufacturers how much to produce. Also, it has a lot to do with strawberries.

All of the sounds or handshapes in a language can be pronounced differently depending on the context, but in different languages, these differences may be significant, or not. The study of these patterns and variations is known as phonology. In this episode of Crash Course Linguistics, weโll learn all about phonology and the different phonological systems we see in different languages, and weโll begin to retrain our brains in order to gain a better understanding and appreciation for phonological patterns.

Weโre picking up where we left off last time, exploring the โethics of careโ and how it applies to extreme poverty. Are we responding to global poverty in a moral way? Philosophers like Peter Singer argue that we have an obligation to prevent harm caused by poverty, whereas Garrett Hardin offers a โlifeboat analogyโ to explain our obligations to focus on caring for our own.

Weathering breaks down rocks and creates sediments which become the raw materials for other rocks and the formation of our soils. And we call the process of moving that sediment erosion. In today's episode, we're just going to focus on the weathering part. We'll discuss mechanical, chemical, and biological weathering and take you on a tour of some of the landscapes they help shape from landslides and sinkholes to caves!

Over the millennia, every region on Earth has developed its own successful agricultural ecosystem from flat fields of grain and mountainside rice terraces to coastal fish farms and goat herding. Today, weโre going to break down agricultural systems into three scales: subsistence, small-scale, and industrial agriculture. And weโll take a look at how a place's history plays a huge role in the system we see today as we follow the story of agriculture in the Philippines.
