Comparison Of Pulmonary Circulation And The Cardiovascular System

The heart is a muscle pumping organ. The bottom tip of the heart, known as its apex, is turned to the left, so that about 2/3 of the heart is located on the body’s left side with the other 1/3 on right. The top of the heart also known as the heart’s base, connects to the heart's blood vessels called the aorta, vena cava, pulmonary trunk, and pulmonary veins. There are two different types of circulatory loops in the human body the Pulmonary Circulation and the Systemic Circulation. The Pulmonary arteries brings blood from the right side of the heart to the lungs where then the blood picks up oxygen and returns to the left side of the heart. The pumping chambers that support the pulmonary circulation are the right atrium and left ventricle.
The blood vessels are responsible for letting the blood flow from the heart to other regions of the body and back again. All blood vessels have a hollow area in the middle which is called lumen and that is where the blood flows through. On the outside of the lumen is the wall which may be thick if it's an artery or thin if its a capillary. The three types of blood vessels are veins, arteries, and capillaries. Arteries are blood vessels that carry the blood away from the heart. The blood carried by arteries is very oxygenated. The blood from the arteries has a lot of pressure as it was just pushed away from the heart. Capillaries are the thinnest of all blood vessels in the body, but are also the most common. Veins are the blood vessels that carry blood back to the heart. Veins rely on gravity and the force of the skeletal muscle contraction to get back to the
There are so many things you can do and avoid to in your everyday life that will help significantly in either avoiding a cardiovascular disease or help to improve your health if a cardiovascular disease is already present. Diet is very important when it comes to your heart eating a well balanced diet low in saturated fats, and highly processed or sugary foods. It's important that your diet contains lots of fruits and vegetables along with healthy fats such as nuts or avocados and foods that contain high fiber. Another way to keep your cardiovascular healthy is exercise especially high cardio exercises that get your heart rate up and working. Maintaining a healthy weight is also extremely important when it comes to your cardiovascular health. The University of Mississippi Medical Center states, "Obesity alone greatly increases a person’s risk of heart disease, even if that person doesn’t have other risk factors for heart disease." By maintaining a healthy weight will allow the body to circulate blood more easily which leads to a lot less work for the heart. Stress also plays a huge role on the health of your heart and cardiovascular system. According to harvard medical school poorly managed stress is linked to increased heart attack risk. stress hormones have been known to narrow blood vessels and
