The heart is a pumping system used to transport blood around the body. It sends blood that needs oxygen (deoxygenated) to the lungs, that oxygenated blood returns to the heart which then dispurses it (oxygenated blood) throughout the body.

__**The Path of Blood Through the Heart:**__ <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 104%;"> Deoxygenated blood enters into the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">right atrium <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">and follows down into the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">right ventricle <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">. The right ventricle pumps the blood out the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">pulmonary artery <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">where it travels to the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">lungs <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;"> to get oxygen. Then the oxygenated blood is sent back to the heart and enters through the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">pulmonary veins <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">and into the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">left atrium <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">, and travels through the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;"> left ventricle <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">. It is then sent through the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;"> aorta <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">and <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">arteries <span style="color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;"> carries oxygen to all parts of the body. Once the oxygen has been spread, the blood travels back to the heart through the <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif; font-size: 110%;">veins <span style="background-color: #ffffff; color: #ff0000; font-family: Impact,Charcoal,sans-serif; font-size: 110%;"> and begins the cycle again. The left side of the heart works much harder <span style="background-color: #ffffff; color: #ff0000; font-family: Impact,Charcoal,sans-serif;">than the right because its function is to pump the blood throughout the body. The right side pumps the blood to the lungs to be oxygenated, then it returns to the heart to be pumped throughout the body. To create the pressure needed to perform this function, the left ventricle is much thicker and more muscular.



<span style="color: #ff0080; font-family: 'Comic Sans MS',cursive;">The cardiovascular system is made up of many blood vessels which are responsible for circulating the hormones produced by the endocrine system through the entire body. Adrenaline is produced by the adrenal glands on top of the kidneys. When circulated, adrenaline raises blood pressure and heart rate. Moreover, the pancreas produces insulin which is responsible for breaking down glucose into simpler sugars that can be used by the body. Blood is responsible moving the insulin from the pancreas to the entirety of the body. The parathyroid glands help to control the blood calcium levels. Another hormone secreting structure of the thyroid, which influences heart rate and blood pressure. In essence, the endocrine system produces a variety of hormones and the cardiovascular system makes it possible to circulate them through the whole body.

​ __** How The Cardiovascular System Effects Other Systems: **__ The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation sends blood from the heart to all the other parts of our bodies and back again. The Cardiovascular System effects the nervous system by helping it maintain homeostasis by supplying glucose and oxygen.

<span style="background-color: #ffffff; color: #eb0000; display: block; font-size: 110%; text-align: center;">The Cardiovascular system works with the respiratory because the right chamber first goes to the lungs and brings back oxygen and contines to the bottom half of the right side where it leaves and delivers oxygen to the rest of the body. -->Link To Respiratory Page<--

The circulatory system is also connected to the muscular system. The heart itself is a muscle. Also, the heart pumps blood around the body, carrying oxygen and glucose to the muscles to keep them moving and giving them energy. <span style="background-color: #ffffff; color: #ff0000; display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: center;">__ The body maintains homeostasis by first constantly supplying the body the central nervous system which includes the brain and spinal cord with oxygen and glucose. Another way the cardiovascular system maintains homeostasis is by constantly beating the heart at a certain beat to pump oxygen throughout the body continuously. It constantly keeps blood moving which helps keep the same temperature of your body.It will also change the speed of the heartrate to maintain the same temperature.
