The Anatomy Of Blood

Our Blood, What It Is and What It Does.

Blood does many things.  Most of us take it for granted.

Three basic parts constitute the red fluid we know as blood.  They are white blood cells, red blood cells and plasma.  Plasma, of which there is about one gallon in the human body, is the salty, straw-colored fluid that white and red blood cells, various nutrients, oxygen and hormones are transported in while on their way to the glands, organs and other body parts.  Red blood cells are tiny: it takes 3000 placed end to end, of the approximately 24 billion in the human body, to measure an inch across.  White blood cells are about 1/1000th as numerous as red cells. 

White cells are in the blood to protect us against bacteria and other invaders. If the white cell count is lower than normal (4.0 to 10.5 X10-3/ul) we may experience more illnesses, colds and flu.  This is not always an indicator of possible problems if the body has the ability to rapidly manufacture white cells in response to invaders.  The rapid response is an indicator of a strong immune function. If we continually bombard our immune system with poor lifestyle and food choices, we’re courting trouble. When the immune system is constantly on alert, even though the white cell count is in or above the normal range, our resistance to illness and disease can remain low. When white cells become to numerous, the results can be leukemia or other blood related diseases like Hodgkin’s or non-Hodgkin’s lymphoma.

Think of the body as you would a large port city.  The main supplies, food and oxygen, come in to port: the mouth and lungs.  After being broken down into smaller units, they’re transported to various distribution centers via canals and smaller boats: the blood stream and blood cells.  

Red blood cells are the bloods’ main player.  A red blood cell looks like a donut without a hole.  The outer sponge-like ring is thicker, tapering toward the center.  Hemoglobin is the carrier of iron and oxygen to the cells.  Hemoglobin is in the outer ring.  Hemoglobin is what gives the arterial blood its red color.  If the blood is deficient in iron and oxygen, the arterial blood is more bluish colored.  This can often be seen as a bluish/white tint in the white of the eye.  Hemoglobin does more than carry oxygen to the cells; it also attaches to wastes and carbon dioxide at the cellular level and transports them, via the red blood cell and veins, to the lungs and other body parts responsible for elimination.  Venous blood is more bluish than arterial blood because the oxygen and iron have been deposited in the cells. Anemia, of which there are two types, is the result of low iron.  Iron poor blood type, the most common, is relatively easy to treat with rest and proper diet.  Pernicious anemia is much more serious and difficult to remedy.

Red cells are manufactured in the bone marrow as needed. Once red cells are manufactured and out of the bone marrow they’re no longer a living cell. Even though they’re the carriers of oxygen and iron they don’t consume an appreciable amount.  Red blood cells are much like an unconcerned, temperamental boat driver.  Red cells want to get paid adequately and proper food is their pay.  If they don’t like what we feed them, they refuse to do their job.

The red cells, which have a life expectancy of 30 to 90 days, go about their job with complete disregard for the rest of the organism.  They have no interest in making certain the cells receive the nutrients carried in their little round boats, and if no new red cells are manufactured to take their place, it’s no concern of theirs.  If the owner of the body doesn’t care, and the blood becomes anemic, it’s none of their business.  Bottom line as far as the red blood cells are concerned?  It’s the responsibility of the owner of the port city to make sure everyone gets sufficient and suitable pay and do the proper maintenance.

Larry Miller: I was born in Los Angeles in 1940. My father was a fighter pilot instructor during WWll and we moved from coast to coast, maybe that’s where I got the nomad in my blood. After graduating from high school in 1958 I joined the Marines. That lifestyle wasn’t for me and upon my discharge I went on with my life, and have never looked back. I worked briefly for a Caterpillar dealer in Riverside, CA before moving back to N. California where I was a welder and truck driver for a chemical company. Truck driving wasn’t my calling anymore than being in the Marines, and I went back to work for another Caterpillar dealer steam cleaning dirty tractor parts and welding. They sent me to schools, lots and lots of schools. I spent as much time going to trade schools as I did at work. I went from cleaning parts to apprentice field mechanic, to mechanic to the parts department to satellite store manager in less than two years. They wanted me to move to Sacramento and be a salesman: I moved to Oregon to learn to commune with nature. I went to work for another heavy equipment dealer and was later contacted by the World’s largest Lorraine Crane dealer and offered the position of purchasing agent and general parts manager. In 1967 I was offered a line of automotive parts and supplies and went into business for myself. My business revolved around eleven race cars that we maintained for others, driving race cars professionally and maintaining high end sports cars. I was a championship and regional champion driver. My business was the largest import parts and service, non dealer, in the state until I sold it in 1979. We went sailing in 79, first to Mexico and then Hawaii. I was an award winning Trans-Pacific sailor and sailor of the year, Hawaii, Island of Kauai. An opportunity presented itself in Hawaii during 1981 and I was back in business, importing Japanese auto body and hard parts. I also felt the pull to write and began freelancing for magazines and newspapers in 1982. My main focus in my articles is, and always has been, health, wellness and fitness. Most of us have heard the saying, “Time is all we have.” I disagree. Our health is all we have, because without our health, we have no time. I was a US Olympic team hopeful in racewalking and held all the records for the state of Hawaii. As a sponsored athlete in my forties, I finished first in nine marathons in a row in my division, qualified for the Ironman® and was the state USCF cycling champion five times in Hawaii and Oregon. Celinda and I were married in 1988 after a three year engagement. We sold our businesses and organic farm and sailed back to Oregon. After our sailboat boat was sold, we moved to Joseph, Oregon, two miles from the trailhead into the Eagle Cap Wilderness. We were caregivers for my mother the last ten years she was alive. We moved to New Mexico in 1995 because it was too cold for my mom in Oregon during the winters. Celinda designed, and I engineered and built our strawbale house. I began writing the weekly health column for a local newspaper in 1996, and still do. In 2000, I took the summer off to do a four month, 4000 mile, hike, bike and kayak odyssey. I’d been writing health, fitness and sports articles since 1982 and the journey produced a full-length, nonfiction, first person adventure book, Yol Bolsun, May There Be A Road, which can be bought from Amazon.com and others over the Internet. The summer of 2001 was spent hiking. kayaking, fishing and exploring the southwest. In 2002 Celinda and I spent the summer in Canada learning the hospitality business at a resort in preparation for doing promotion for the resort in the US. Most of 2003 was spent reestablishing the trees and landscape that had died during the stay in Canada. We had a house sitter and the house sitter had an ex-husband, and that’s a long story. In July of 2004 I did a solo kayak trip on the Snake River, taking pictures, writing articles and pencil sketching the journey. I hope to do another kayak adventure on the Snake River during the summer of 2008, on the section I missed in 2000 and 2004. In 2005, I returned to Canada to the resort where we’d spent 2002. I was supposed to be there for the month of June. I’d contacted people I’d met in 2002 and they came back to Canada to fish, hike and spend time at the resort, Echo Valley Ranch and Spa, while I was there. My one month became five and then it was off to Spain to do the El Camino de Santiago as a travel companion with one of the guests who’d returned to Canada in June. During the summer of 2006 a friend from Ireland, who I’d met in Spain the year before, came to visit in NM and we fished, hiked and explored the White Mountains of AZ. He’d never slept out in the wild in a tent before, and it was quite an experience, for both of us. My newspaper articles were put on the Internet beginning in 2002. I was asked to give public speaking engagements, photo and video presentations, on various subjects for the library in Deming, NM and continue to do so. In 2006 I videoed and produced a DVD for the Smithsonian Institute’s travel exhibit “Between Fences.” NMFILMS had a conference by invitation only, which I attended. While attending the conference, I realized that film making wasn’t what I wanted to do but I still wanted to use my sixteen years of experience and enjoyment of videoing and photography. During the winter of 2005, I discovered that no one on record had ever run from the Arizona border to the Texas border, a distance of 165 miles. During the spring and summer of 2006 I trained for the run and the run was completed in October, 2006. In late 2005, I began building and maintaining websites incorporating all the things I enjoyed about video, photography, travel and the out of doors. 2007 has been a summer of upgrading the home and property which resulted in a downgrading of my enthusiasm for being located in one place. If we don’t like what’s happening in our life, we need to change what we’re doing. Celinda and I are ready to pull up roots and move on. I guess I’ve come full circle. I’m ready to revert back to my childhood, and a nomadic lifestyle.
