Blood is transported through the body by the heart's pumping action. As we continue, we will enter the hepatic portal vein, which delivers blood from the gastrointestinal tract to the liver, into the ascending aorta, up towards the heart. As we approach the heart, it's pumping will pull us up into its chambers and through to the lungs where we will get oxygen and continue our journey to the kidneys. As we return to the heart, we will pass through the aortic arch and descend through the thoracic aorta continuing past the descending abdominal aorta until we reach the renal artery. We will make a left turn and pass through the glomeruli through the kidney's tubules and conclude this phase of our journey into the left kidney. The last stage of our journey will take us through the kidney and into the urinary system where we will conclude our tour as we exit the human body. The human kidney is made up of the cortex, medulla, pyramids, papilla, renal pelvis, and calyces. In order to complete our journey, we must pass through a nephron back into the glomerulus. Each glomerulus is covered by the Bowman's capsule. Please note the high level of pressure present. This pressure is a necessary component of filtration in the kidneys. The glomeruli and Bowman's capsule make up a renal corpuscle. Filtration begins when the blood flowing through the glomeruli exerts pressure pushing water and dissolved substances out of the glomeruli and into the Bowman's capsule and continues filtration through the glomerular-capsular membrane. This glomberular filtration usually occurs at a rate of 125 ml per minute....
Unwanted wastes and substances move into urine through the distal and collecting tubules from blood in capillaries surrounding these tubules. This urine will drain out of the collecting tubules into the renal pelvis through the kidney's ureter and down into the urinary bladder. Notice the mucosal membrane that also coats the ureter and renal pelvis. The ureter has a thick, muscular wall that will help move urine down the ureter into the bladder through peristaltic contractions. To leave the body, we must travel past the trigone and down into the urethra where we will conclude our journey. The urethra in this test subject is approximately 8 inches in length.
Journeys in Yiddish Literature The Yiddish writings, Nachman of Bratslav's "Tales of the Lost Princess," Tsene Rene: The Creation Jacob Ben Isaac Ashkenazi, and Ma'aseh Book, all present a journey of faith and trust. Although some of the stories are actual journeys to distant places, they too represent a journey of the soul, a journey into the unknown armed only with faith and perseverance. These writings are teaching tools of faith
3. The Hero Telemachus There are numerous features possessed by the Greek heroes. One of these features is their annexation or even relationships with the gods of the time. The characters in the Greek poems are generally simple men with exquisite qualities, but who are just as weak and mortal as all humans. This is also characteristic of Telemachus. He is a courageous man, descended from gods (he is the descendent
religion entered the 18th Century and with it a revival. The growth of the revival was overwhelming.More people attended church than in previous centuries. Churches from all denominations popped up throughout established colonies and cities within the United States. Religious growth also spread throughout England, Wales and Scotland. This was a time referred to as "The Great Awakening" where people like Jarena Lee got her start preaching. Evangelism, the epicenter
Melancholia sat in, as the loss I felt became less and less related to my body. I began to court death first symbolically and then literally. Freud would have noted the presence of the death wish in addition to describing the symptoms of "melancholia," or depression. Symptoms include "a profoundly painful dejection, cessation of interest in the outside world, loss of the capacity to love, inhibition of all activity,"
character in Gilgamesh undertakes a journey which is more than a trip from one place to another. This kind of journey is a quest, a quest for self. Gilgamesh is trying to learn who he is and to understand his place in the world, and this is the quest he begins, a quest that takes him far and that takes a lot of time to complete. The physical journey
American Immigration Globally, the United States has been known as "a nation of immigrants" almost from its inception. Beginning in the 1600s with English Puritans and continuing today, America is a melting pot of culture and ethnicity. In fact, in the late 19th and early 20th centuries, immigration was the major source of U.S. population growth. Looking over our 200+ years we find that to clearly be true, with approximately
