Coronary arteries are one of the most important parts of the body because of many different factors. Heart muscle needs blood rich in oxygen to function and pump more blood throughout the circulatory system. If the blood does not carry enough oxygen, the veins will carry it away. Blood can only be delivered when the heart is relaxed; because once they contract they become narrow. These arteries are structured differently as opposed to many of the other arteries in the human body. The coronary…

About blood Functions Blood is the biological fluid in our body that transports nutrients and oxygen to the cells, and also exports the metabolic waste product away from the cells. To ensure the supply of oxygen needed by our organs and tissues, there are four important steps: 1. The oxygen must be transferred from our lungs into the blood plasma 2. The oxygen is stored on the hemoglobin in the red cells 3. The oxygen is transported to our body cells via circulation. 4. The oxygen is released…

Mechanical Ventilator is a life support system that mechanically assist patient in the exchange of oxygen and carbon dioxide. It can also be called as artificial respiration system. Mechanical ventilation can help or support complete breathing, depending on the patient’s condition. Anyone who have problem in breathing normally, or having chronic diseases may require mechanical ventilator. It also includes patients suffering from spinal cord injury, stroke or any other disorders. Rapid growth in…

The portal venous system is very important in that it collects blood from the spleen, the stomach, pancreas, and the small and large intestine. All the veins from the portal venous system will come together to form the portal vein which then carries substrate-rich venous blood to the liver. The blood in the liver will then be drained by the hepatic veins. Portal hypertension is associated with chronic liver diseases and is a result of an increase in blood pressure in the portal vein. There is a…

endothelial and parenchymal cell. It is a t the point that this proliferation and migrations occurs as epidermal skin cells in the top layer move down the sides of the wound to help fill the gap. Fibroblast move in from the dermis, and new blood vessels from to create granulation tissue, which later becomes scar tissue. The next phase of remodeling eventually progresses into the final maturation phase of remodeling eventually progresses into the final maturation phase as the regenerated tissue…

Normal function of Respiratory System The function of the respiratory system is to provide the entire body with oxygen while simultaneously getting rid carbon dioxide through the process of ventilation (Shoopman, 2015, p.513). The respiratory system is split into two different sections: the upper respiratory tract and the lower respiratory tract (Appendix A). As air enters the body, it first passes through the upper respiratory tract, which consists in the order of the mouth and or nose,…

About the size of a large fist, heart is made up of cardiac muscle, myocardium, with skeletal muscle-like striations. It has two upper atria & two lower ventricles separated vertically by septum, and four main valves with which the blood makes its directional flow into and out of the heart. Deoxygentated blood with which the blood flows into and out of the organ. Deoxygenated blood enters through the venae cava fills the right atrium (RA) and right ventricle (RV) through the tricuspid valve.…

Fetal circulation differs greatly from that of a newborn heart. Although, outwardly appearances may seem similar. By taking an internal look we may be able to distinguish four adaptations that fetal hearts undergo while in utero. First, we must understand that the fetus receives all blood and nutrients from the parental placenta. The fetus receives this blood from the placenta through the umbilical vein. This is the first adaptation that we see in the fetal cardiovascular circulatory system.…

cardiovascular system works when a person breathes air through their mouth and nose and then it travels the lungs. Oxygen from the air is slowly absorbed into the bloodstream through the lungs. The heart then pumps oxygenated blood through a network of blood vessels, the arteries, to the tissues including the organs, muscles and nerves all around the body. When the blood reaches the capillaries in the tissues it releases oxygen which assists the cell in producing energy. These type of cells…

NITRO, W.Va. — On a rainy Friday afternoon, Dave Riley was inside the Nitro World War I Museum, eating lunch pizza, checking his phone and talking to a handful of residences. It was a day before he was supposed to deliver a keynote speech at an event honoring the city's Living Memorial Park. Nitro, which was founded during World War I, was holding the event has part of its dentinal celebration. Riley, who is from, Mobile, Alabama, was visiting the city to take part in its dedication of the…
