1. What is the function of the blood? What specific materials does it transport? Why are these substances important? Be specific – explain why these substances contribute to homeostasis.
Blood is composed of plasma (clear extracellular fluid) and cellular components, which consist of red blood cells, white blood cells, and platelets. Necessary body fluids, nutrients, gases, chemicals, and wastes are transported throughout the body by the blood. The functions of the blood include respiration, waste elimination, thermoregulation, nutrient delivery, immunity and defense, hormone delivery, and water and pH balance.
Blood transports oxygen from the lungs and nutrients from the digestive tract to all cells of the body. Metabolic waste products are transported from cells to sites of elimination; for example, to the lungs for removal of carbon dioxide and to the kidneys for dumping of nitrogenous wastes in urine. Blood additionally transports hormones to their target organs.
Blood regulates an appropriate body temperature by absorbing and distributing heat throughout the body and to the skin surface to support heat loss. Normal pH in body tissues is regulated by blood. Blood proteins and other blood borne solutes act as buffers to stop extreme or sudden changes in blood pH that could endanger normal cellular activities. Blood additionally acts as the reservoir for the body’s alkaline reserve of bicarbonate atoms. Proper fluid volume in the circulatory system is maintained by the blood. For example, salts and blood proteins act to stop extreme loss of fluid from the bloodstream into the tissue spaces. This results in the blood vessel fluid volume remaining ample to assist efficient blood circulation to the entire body.

...become sticky and accumulate together. In thrombin dilution, clot formation away from the site is prevented by thrombin dilution and antithrombin presence in the plasma. The amount of activated thrombin will decline because of dilution and the activity of antithrombin, which decreases fibrin formation. Natural anticoagulants include antithrombin and heparin. Antithrombin is produced by the liver; it deactivates thrombin before it can act on fibrinogen. Heparin is secreted by basophils and mast cells; it disrupts the creation of prothrombin activation.

In Blood In Blood Out is a drama directed by Taylor Hackford, and starring Damian Chapa (Miklo), Benjamin Bratt (Paco), and Jesse Borrego (Cruz), produced by Hollywood Pictures. The film was based off everyday life in East Los Angeles, from the 1970’s through the 1980’s. Damian Chapa stars as Miklo in the film, a Mexican-American who wanted to be accepted, not by his skin but for the Mexican within him. Benjamin Bratt (Paco) was the older cousin of Miklo, who learned his lesson throughout the movie and changed his ways. Jesse Borrego (Cruz) is the step-brother of Paco who was a talent artist, who ended up turning to drugs because of back problems caused by a rival gang incident.
Red blood cells deliver the oxygen to the muscles and organs of the body.
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
While the respiratory and cardiovascular systems are most reliant on one another, all body systems require a functioning circulatory cycle in order to thrive. Consistent transfer of oxygen through blood vessels is required to maintain cell and tissue life. Without this cells and later tissues will die Disturbances to this process cause cells and tissues to die (Red Cross 48). This required state in which all body systems are functioning properly is called homeostasis, defined as a “condition of equilibrium in the body’s internal environment due to constant interaction of body’s many regulatory processes.” This process also can help regulate any disruptions or changes within the body (Tortura, 8.
Wallace Terry has collected a wide range of stories told by twenty black Vietnam veterans. The stories are varied based on each experience; from the horrific to the heart breaking and to the glorified image of Vietnam depicted by Hollywood. Wallace Terry does not insinuate his opinion into any of the stories so that the audience can feel as if they are having a conversation with the Vietnam Veteran himself. Terry introduces the purpose of the book by stating, “ Among the 20 men who portray their war and postwar experiences in this book. I sought a representative cross section of the black combat force.”(p. XV) Although the stories in this book were not told in any specific order, many themes became prominent throughout the novel such as religion, social, and health.
For homeostasis to work the transport, respiratory, gastrointestinal, renal and cardiovascular system have to function together.
In order for the cells of the body to work correctly they require a constant stream of oxygen in order to stay alive. The respiratory system provides the cells with oxygen while simultaneously removing carbon dioxide. The three parts of the respiratory system: the airway, the lungs, and the muscles of respiration.
The spleen stores blood. The spleen is made up of two types of tissue which consist of the red pulp and white pulp. The function of the red pulp is to store and remove red blood cells. The white pulp consists of localised areas of lymphoid tissue within the spleen and produces the lymphocytes. ( Reeder et al., 2009).
The metabolic pathway being mediated by the CYP2C19, CYP3A, CYP2B6 and CYP1A2 enzymes. The maximum concentration with a single dose of 300mg loading dose is twice as high as it is after four days of 75mg maintenance dose which occurs approximately 30 to 60 minutes after dosing.
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
The purpose of this experiment was to gain a general understanding of osmosis, osmolarity, and tonicity and to further investigate the effects that specific solutes, such as NaCl, had on the structure and physiology of red blood cells. The first portion of the experiment consisted of the dilution of stock blood solution suspended in isotonic, or 0.9%, saline solution. As the blood stock solution was diluted, the number of blood cells greatly decreased when viewed under the microscope (Figures 1 and 2). This decrease in cell number and disfigurement of cell morphology can be attributed to the increase of the dilution factors. In other words, as the dilution factor increased, the number of cells on the each test tube drastically decreased, resulting
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
Many people throughout the world visit the United States every year to receive medical treatment. This is due to our excellent pharmaceutical industry as it spends million of dollars and many hours of research to come up with what we can only describe as “miracle” drugs and treatments. Part of the success of many of these medications is because the pharmaceutical industry is highly regulated by policies that protect the public from accessing drugs that have not been fully tested and found to be “safe”. However, this was not the case until the late 1990s and early 2000s. One time in history that highly influenced the strict regulations we currently have was the nationwide contamination of patients through blood transfusion or by consuming medications
Blood transfusions are potentially life-saving procedure that can help replace blood lost due to surgery or injury. Every two seconds someone in the United States needs blood (Blood Facts 1). Blood has been used as a form of therapy for a variety of ailments dating back as far as the 17th century. There is no question that blood is an incredibly valuable resource. Over the years, there have been several significant advances made in not only the research of blood but also medicine. The history and research of blood transfusions has brought the discovery of blood types and the incompatibilities of said blood types.
Our blood is able to connect all our organs together to create one organism and is able to transport the most vital and important molecules through these blood streams. Hence, blood cells are needed for immune system function and metabolic functions.
