Heart:
Heart has 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood comes back to the right side of the heart with the venous circulation, pumped into the right ventricle and then to the lungs, there, carbon dioxide is released and exchanged with oxygen. The oxygenated blood then travels back to the left side of the heart into the left atria, heading to left ventricle, aorta, and finally arterial circulation. Blood travels from right side to left side via the lungs only.
The pressure created in the arteries by the contraction of the left ventricle is the systolic blood pressure. After the left ventricle contracts, it begins to relax, then refills with blood from the left atria, meanwhile the pressure in the arteries falls, this is the diastolic blood pressure. In other words, during systole, cardiac muscle tissue is contracting to push blood out of the chamber; during diastole, the cardiac muscle cells relax to allow the chamber to fill with blood; systolic blood pressure is the higher number and diastolic blood pressure is the lower number.

Pericardium produces serous fluid to lubricate the heart and prevent friction between the beating heart and surrounding organs, and assure its
The purpose of arterial pressure and the pulse lab is to determine the effect of posture and exercise on systolic and diastolic pressure and the heart rate. And also in order to find the differences in the reading taken under these condition compares to the baseline reading. The Sphygmomanometer and stethoscope are used to measure the systolic and diastolic blood pressure, counting the beat on the radial artery will give the reading for pulse rate and by using the lab scribe software and IWX214, the blood pressure will be measured. In the heart, the aorta and the carotid arteries have baroreceptors and the chemoreceptors that identify the changes in arterial pressure and the changes in
The oxygen rich blood returns from the lungs and it goes through the pulmonary vein to the left atrium.
Once deoxygenated blood enters the right atrium, it travels through the tricuspid valve into the right ventricle. Then the blood goes through the pulmonary semilunar valve into the pulmonary arteries. Once in the pulmonary arteries the blood is pumped into the lungs where it is then oxygenated. The blood goes from the lungs through the pulmonary vein into the left atrium. From there it passes through the bicuspid valve into the left ventricle where it is then pumped out through the aortic semilunar valve into the aorta (Drake 101). From the aorta the blood goes to the right and left coronary arteries.
First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.
Likewise, Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle, forming the complete circulation.
In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left
The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.
The oxygenated blood then leaves the lungs though the pulmonary veins, which returns the blood to the left atrium. Once the blood has re-entered the heart it flows through the bicuspid valve, and into the left ventricle. The one-way valves are important for preventing any backward flow of blood. If blood started flowing the wrong way, the blood gases would mix, causing a serious threat to the body. The blood is then pumped through the aortic valve into the aorta to then circulate through the systematic
When blood enters through the inferior and superior vena cava, into the right atrium, from the pulmonary veins into the left atrium. The right atrium contracts slightly before the left because it is first to receive the signal. During this contraction, diastole is occurring, the ventricles expand, and their pressure drops below the atria, which causes the AV valves to open and blood flows into the ventricles, causing pressure to rise and atrial pressure to fall.
The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).
Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work
A healthy heart pumps blood continuously through the circlutory system. It’s normal size is a little larger than a fist. The heart has four chambers, two on the right and two on the left. The two upper chambers are called the atria and the lower two are known as the ventricles. The right atrium takes in deoxygenated blood from the rest of body and sends it back out to the lungs through the right ventricle where the blood becomes oxygenated. Oxygenated blood travels from the lungs to the left atrium, then onto the left ventricle, which pumps it to the rest of the body.
The heart is basically a pump that has to circulate the blood around the body delivering oxygenated blood to our organs and then returning deoxygenated blood to our lungs. There are four chambers in the heart, two atria and two ventricles. There are four main valves, mitral, aortic, tricuspid and pulmonary7b.
The oxygen-rich (oxygenated) blood return from the lung to the heart through the pulmonary vein and into the left atrium. The mitral valve them opens and blood is pumped into the left ventricle. (this happens at the same time as the right atrium pumps blood into the right ventricle). (Dao, 2017)
