This occurs because now the interstitium has more of the substance than your blood does. (difference) forms between the blood and interstitium. ![]() When HD removes a waste or fluid from your blood, it only reduces your Okay.focus is crucial that you understand this next bit! Any substance that is removed by HD must be, at least Have direct contact with the environment-the interstitium-in which your cells live and work. So.what has all this got to do with the speed, length, and frequency of HD and how you feel during, after, and between HD sessions? Time, frequency of delivery and removal and ease of transport -these things really They may even need special lifting and carrying devices to shift them. Little things are easily carried and don't take long, but bigger things take longer and need more effort. Any waste made by the cells must first pass into the interstitium then through the interstitium and into the blood before it can be carried away.īut, you know, it can take time to offload a truck, to carry things in and carry things out again. In turn, the interstitium is fed and cleaned by the blood stream. Cells are fed and cleaned by deliveries back and forth through the interstitium. Or, it can be slow and laborious: a piano to get up a top-floor apartment or a king-sized bed or sofa to manhandle up the stairs. You know this can be a quick-as-a-wink delivery or pick-up, like a mail delivery or an empty bottle to throw away. It must be carried into or out of the house or the office. Anything you need or that must be thrown out must first come from or go to the road system. It acts as the interface between you and the roads that bring your goods and dispose of wastes. They form your support systems, the "interstitium" that surrounds and nurtures you. In the body, we call them organs.ĭay by day, you work in an environment made up of your home, office, and suburb. ![]() In a real city you might call these groups organizations. They work and function independently of each other-but also together in groups. Single cells are the people in your city. And proteins and other carriers are the garbage trucks. White cells are police and emergency services. The "arterials," smaller highways, lanes and alleys, are all full of cars and trucks. It may help you to think of your body as a huge city. It also carries away the wastes and toxins your cells make as they do their daily work. Blood carries oxygen and nutrients to supply the cells. And tiny cells called platelets help the blood to clot in response to injury. White cells offer us protection and immunity. The bloodstream.įinally, there is your blood itself: a mixture of water, salts, proteins, and cells. This compartment has a somewhat different content of salts (electrolytes) than the fluid inside the cells-especially for salts like sodium and potassium. It is also called the " interstitium" (in between), the " extracellular fluid compartment" or the " interstitial fluid compartment"-just to confuse the hell out of us! This is the " extracellular fluid," the fluid The water that makes up the bulk of your cells is the " intracellular fluid compartment" -fluidĬells live in a kind of primordial "soup," a fluid bath that nourishes them and keeps them fed and happy. They have structure, yet they are mainly water. Yet, a watermelon is 97% water.Ĭells are like that, too. Like your cells, a watermelon looks solid-and if you dropped one on your foot, you would agree it feels solid. The sum total of your cells makes up the tissues and organs of your body. Inside your cells.Įach cell of your body is a tiny living building block. Your body has three distinct fluid "compartments": 1. More HD more gently-yet also far more completely-restores the chemistry of your blood and body.More HD is much better for your heart and circulation.You'll feel better during and after HD. ![]() There are three main reasons why I think longer and/or more frequent hemodialysis (HD) are better for you: Fluid and Solute Removal: How and Why (Part One)
