I start my journey in bone marrow. Have you ever seen how flexible bone marrow is!?! It’s really exciting. I form from hemocytoblast which takes about 2 days. The body makes about two million red blood cells every second. So there’s a lot of me to go around. I finally get to leave and make my way through the veins capillaries along with my buddy plasma. We take up most of the room since there’s so much to go around, but on my behalf those guys aren’t that big to begin with. Eventually I go to what I like to call the big brother of the vein capillaries the arteries. Those are so much bigger but they do more work and they are stronger the capillaries are nowhere near as strong! I eventually make my way to your heart! If you close your fist, that’s about the average size of your heart. The heart pumps about 2,000 gallons (7,571 liters) of me a day through its chambers, no you don’t have the much of me in your body but it pumps me over and over. Your heart receives me already oxygenated in the same way your brain, foot and the rest of your body do: through an artery. Now although the h...
I am now reporting to you from the patient’s femoral vein. I am headed north to her right lung. The femoral vein is one of the largest veins in the body. The ride has been smooth so far. I have been seeing many different types of cells go by my submarine window. I just saw an army of white blood cells headed the same way that I am. They most likely are headed towards the bacteria infestation in the right lung. I am also hearing the heart beat; it is making a LUB- DUB sound. I can also hear the blood flow; it is making sort of a swooshing noise. That noise is reminding me of the ocean! The right femoral vein is now turning into the external iliac vein; I am now by the urinary system and reproductive system. This is also known has the pelvic region. As we continue north the eternal iliac vein is now called the common iliac vein. As we continue on, the common iliac vein is now called the inferior vena cava. We are getting closer to the heart! We are in the abdomen of the body. There are diff...
both these sysmtems work with one another to ensure that organs tissues in the body are supplied with an adequate amount of oxygen, and that carbon dioxide can be removed. firstly through the respiratory system, oxygen is inhaled through the nose and mouth, the oxygen is will travel down the trachea, the rachea divides into the bronchial tubes which enters the lungs. the bronchi divides into smaller branches known as the bronchioles, which have tiny air sacs called alveoli on the end. The alveoli is surrounded by thin blood capillaries, the wall of the capillaries is a single layer of cells. These thin walls allow gas exhange to take place. Oxygen will be diffused in the capillaries and will go into the red blood cells, where it will then be transported back to the heart. carbon dioxide will be diffused though the capillary walls into the alveoli, in an opposite path than oxygen. carbon dixoxide will be released in the lungs and through exhalation the carbon dioxide will be removed.The right atrium of the heart will supplied with de-oxygenated blood by the superior and inverior vena cava. The right atrium will pump the de-oxygenatd blood via the atrioventricualr valve until it reaches the right ventricle. the right ventricle will pump the de-oxygenated blood via the pulmonary semi-lunar valve, which will carry the blood pass through the pulmonary arteries unti it reaches the lungs. these veins from the lungs will carry oxygenated blood to the right atrium. the right atrium will now pump this fresh oxygenated blood past the aventricular valve so it can enter the left ventricle. the left ventricle the thickest out of the four chambers and will pump, so that oxygenated blood is supplied to all the organ tissues in the
The first half of my book “The Cellar” written by Natasha Preston, was so good that I could not put the book down. The girl, at that point, had no memories which include her name and anything before she woke up on a dirty, bloody cabin floor. She looked down at her throbbing hand and found that two of her fingernails were missing.

Throughout Chapter 39, you are introduced into the major concepts of the circulatory system, the lymphatic system, the heart and how blood flows through it, and the respiratory system as well as the path of airflow through the respiratory system. In Section 1, you are introduced to arteries, capillaries, and veins as well as what consists of blood plasma. You are also introduced to the different blood cells and cell fragments such as red blood cells, white blood cells and platelets. In Section 2, you are introduced to both the pulmonary circulation loop as well as the systemic circulation loop. You are also introduced to how blood flows through the heart, as well as how contractions take place throughout the heart. Lastly, in this section you
Brock awoke to the sound of a trumpet. He was ready to get training. Brock put on his long johns, pants, shirt, coat, and hat. Then he slowly walked out of his tent. When he walked out he was greeted by Major General Wayne. He said, “Follow me i'll show you where you will be training.” Brock followed him for a about a mile until they walked into a large field with hundreds of saddled horses, and about 80 other men. Major General Wayne said,
The fog was heavy, the distance we were able to see was less than 30 yards from our position.
Oxygen is going from the capillaries to the tissues, and carbon dioxide from. tissues taken up into the capillaries. Arteries have to be strong as well as flexible because of the pressure of the blood being pumped. through the venous system. Veins get bigger when they get closer to the heart of the world.
The process for an adult’s circulation system starts with non-oxygenated blood entering the right atrium from the inferior and superior vena cava. Once in the right atrium the tricuspid valve opens and drains the blood to the right
As blood travels through the circulatory system, it is first pumped from the right side of the heart to the lungs through the pulmonary arteries and then separates into arterioles which split into capillaries. Here, the deoxygenated blood receives oxygen diffused in the lungs due to large surface area and travel back through venules and then pulmonary veins to the left side of the heart. From here, the oxygen rich blood is pumped throughout the body in arteries, arterioles, and capillaries, providing the body and cells with nutrients through osmosis. Afterwards, the now deoxygenated blood travels back to the right side of the heart containing deoxygenated blood, through venules and vein to repeat the cycle over again. Also, the heart is nourished by coronary circulation through the Right and Left Main Coronary Arteries.
Honey, this has been the longest year of my life, life here is absolutely terrible. It’s only been a year since I have been ranked to Specialist E-7 and sent to Verdun and it has been nothing but pure chaos. As of Last week the 21st of February at 7:12 AM the first shot from a German Krupp landed at Verdun. Lifting up your head you can only see bullets flying everywhere nonstop, it’s a constant battle for land and to weaken the oppositions army. We were told to stay low until ordered to fire, but then our Commanding Officer almost forced us into charging into the Krauts Trenches. Luckily they chose to send a different divisions to risk their lives, God bless their souls. Though since they charged we got bombarded with hundreds of shells the next few days. Disease ran rapid as well, such as Trench Foot it has been a major disease here, my friend Private John Huberts shot himself in his foot after getting this disease, he’s been sent back to Dijon to be treated ever since I haven’t heard from him since. The mud is the second worst part of these trenches, though the constant Rats running around definitely take the cake, every night being woken up from these rats running across you is infuriating for the most part. Also these rats have been eating all our food supply leaving many to starve in the trenches.
The war has been more than I could ever imagine. I have seen such horrific sights, that will remain with me for as long as I live. War is not as they tell us back home. There is no dignity and pride in killing another man; there is only damage and grief. War is exhausting. Half of us do not even understand why we are here, except to kill the Germans. We just want to be home, even the Germans have families they miss too. The trenches we have been staying in have been especially brutal. We stay here for days on end, staring into fields of shrubbery, waiting for the Germans. Sleep is limited and cherished.
The day has come. The day I've feared but tried so hard not to. Two men grab me by the arms and lead outside to the blinding sunlight, reluctantly. My tattered shoes scrape along the rocky sand of the camp, everyones watching me now. They all know what's happening and feel sorry for me, except for a smug figure in the distance, obviously Sergeant Hanley. My eyes dart helplessly around the camp, I see the firing squad and a lump swells in my throat. Then I see Tommo, and remember my promise to him.
After his close encounter of the dumbest kind, Freddie makes his way into a small driveway that leading to the back part of the apartment complex. Once in there, his eyes are delighted when the four green dumpsters catch his vision. However that’s not the only thing going on back there, several boys have that distrustful look about them as they carry boxes [with the exact dimensions and labeling] commencing from one building to another. Back and forth, they go like soldiers, Freddie knows they are up to something.
One of the most unique creatures are fish. As I am sitting here in my room, my fish are swimming about with not a care in the world. I wonder what it would feel like to be a fish.
