Cardiovascular Lab Report

The cardiovascular and respiratory systems work towards a common goal of getting oxygen to tissues and getting carbon dioxide out of the body (Cloe, 2013). Each system has their own function to help the other, but the main focus is to oxygenate the blood. The body does this through one of the bodies organs, the lungs. Low oxygenated blood is pumped through the pulmonary arteries to the lungs. Whenever we breathe this low oxygen blood is turned back into oxygenated blood when carbon dioxide is forced into the air and oxygen reenters the body. The reoxygenated blood then reenters the heart. For this lab, the expected outcomes are that when the heart rate and blood pressure are measured, both will increase when the heart has to pump against gravity, after exercise the heart rate will increase then return to normal, and as the subject inhales, it will be lower than when they exhale.
Methods
For this lab report, the laboratory manual (2009) was used for all labs. While completing lab five, electrodes were hooked up to the subject. After calibration for this lab,
For lab seven and sixteen, pulse and blood pressure were taken. The subject of these labs is unknown because our data was collected from a different group. Lab seven used electrodes and a pulse transducer on the right index finger. The subject for this lab sat in a seat relaxed for fifteen seconds, seated with their hand in cold water for thirty seconds or as long as they could stand, and then seated with their right hand above their head. Data was collected then the students moved on to lesson sixteen. For lesson sixteen a pressure cuff, stethoscope, and electrode set were used. The cuff was placed on the left arm and the blood pressure was taken. The subject’s blood pressure was taken on their left arm twice while sitting then on their right arm twice while sitting, twice while lying down, and then after exercise. The data collected was
