Inferior vena cava

other areas that in a newborn and adult will not go to. When this circulation first begins it is due to the fetus receiving oxygenated blood through the umbilical vein, that came directly from the mother’s placenta. The blood then travels to the inferior vena cava rather than the liver where it wants to go;…

The Heart Every human to ever exist carries a hard working pump inside their chest. The pump is called a heart, and the heart’s main function is to deliver a supply of blood through blood vessels throughout the human body. According to research, the heart is a muscle that repeats the same pumping action during the whole lifespan of an individual and is about the size of ones fist. The heart is made up of several elements like the aorta and the mitral valves, along with other vital parts.…

Humans are terrestrial but they don 't usually live wild in nature ,they make their own environment adapted to their needs, however humans have to live in a place where they can get consistent food supplies such as cow, pigs, chickens and plants. Oxygen and water is essential for human. Humans control their own competitors, predators, parasites, and diseases,humans require large and continual subsidies of energy, food, and other resources. These are needed in order to maintain the colonization…

Explain the significance of the thickness of the left ventricular wall. The left ventricle works harder as it pumps blood to the systemic circuit, not just to the pulmonary portions as the right ventricular does. Therefore, the left ventricular walls are thicker, to support the hard work that it has to do throughout the body (Martini & Nath,2014 p.685) The major coronary vessels are on the surface of the heart. What is the advantage of that location? The heart has its own blood supply from the…

capillaries of systemic tissues where the vital two-way exchange of substances occurs between blood and cells. Next the blood will flow out of each organ capillary beds by way of its venules and then veins to drain eventually into the inferior or superior vena cava, and through these two great veins into the right…

Interrelation between the cardiovascular system and the respiratory system The cardiovascular system and the respiratory system can interrelate to perform a function such as exercise. In order for the body to move our muscles require oxygen. While the body’s muscles are working there is a constant delivery of oxygen to the muscles. The oxygen is taken to the muscles during exercise as a result of the circulatory and respiratory systems working together. The heart, blood and the lungs are the…

what level activity we did. Heart rate is when the heart contracts because it is pumping the oxygenated blood through the aorta. Then the blood goes through your heart through the vena cava. Once you start moving the blood go through the capillaries to your lungs, legs, head and arms the blood flows through the inferior and superior capillaries. The part of the heart blood that that keeps the blood from flowing backwards would be the valves. Hypothesis: I hypothesize that if the faster and…

Blood Blood consists of: -White blood cells -Red Blood Cells -Plasma -Platelets White blood cells (WBC Are also called leukocytes. They are the first line of defence when it comes to the human body fighting off infection. When something foreign enters the body the immune system snaps into response by sending white blood cells to fight off the infection. They either produce protective antibodies or they devour the bacteria. On average a human would have a White Blood Cell Count of 7,000 in each…

pulmonary congestion – these are characteristic of left-sided heart failure. In right-sided heart failure, hepatomegaly could occur due to the increased pressure within the hepatic vein; ascites could occur because of the pooling of blood in the inferior vena cava; and pitting edema could also occur due to increased fluid retention in the veins (from increased capillary…

The spleen can be found in the left upper quadrant of the abdomen, lying posteriorly to the stomach and underneath the diaphragm. The spleen can be found enclosed in a capsule of dense irregular connective tissue (Krause, 2008). Prone to infections and other conditions, the spleen can easily become enlarged because it is highly vascularized. Malignancies, parasites, liver diseases and other conditions passed in the blood and immune system can cause the spleen to be infected. In addition to the…
