Homeostasis within the body can be measured by the main vital signs: heart rate, temperature, respiratory rate and blood pressure. pH is also important to measure homeostasis, but cannot be readily measured without drawing blood. Each of these measurements are controlled by body systems, that work together to maintain proper ranges. The metabolism is a measurement of the chemical energy needed to run these systems, which are fueled by cellular respiration, a process that breaks down glucose and converts

usually not dangerous. A normal heart rate is 60‒100 beats per minute. During an episode of SVT, your heart rate may be 150‒250 beats per minute. During episodes of SVT, the heart beats so quickly that it does not have time to fill completely with blood. When episodes happens often or last for long periods of time, the heart can get weak and heart failure can result. CAUSES This condition is caused by abnormal electrical activity in the heart. It is not known why some people get SVT and others do

heart is like an engine, pumping blood throughout the body. Over time, when this pump cannot distribute enough blood throughout the body to meet its needs, it develops into a condition known as congestive heart failure. When the right side of the heart fails, the lungs cannot pick up oxygen due to the heart’s inability to pump enough blood to them. In contrast, left sided heart failure is related to the heart’s inability to pump an adequate amount of oxygen-rich blood throughout the body. Only one side

The job of the lungs is to bring in oxygen and then oxygenate the blood, but COPD disrupts this. As less fresh air enters the lungs, the less oxygen someone will get to oxygenate their blood which can lead to hypoxia. The likelihood for a heart attack increases as the heart receives less oxygen. Pulmonary hypertension can also occur as COPD progresses. This can be caused by the pulmonary arteries constricting due to hypoxia, dysfunction in the endothelial tissue, and the pulmonary capillary bed
