The Cardiovascular System Notes Name_______________________ Functions 1. Carries needed materials like _________________ and ___________________ 2. Removes ___________________ like _____________ ______________. 3. Fights ___________________ Organs of the Cardiovascular system 1. ___________________ 2. ___________________ 3. ___________________ 4. ___________________ Heart Its function is to pump _____________ through the cardiovascular system. It is made of ______________ _______________ . This muscle is ______________ and it never tires and is _______________ . Heart Structure 1. The two sides of the heart are separated by a ________________ 2. The top chambers are called ________________ and the bottom are called _______________. 3. A ________________ is a group of cells that start each muscle contraction 4. The _________________ are flaps that stop blood from flowing backwards How the heart works 1. Phase One - Muscle _____________ and heart fills with blood 2. Phase Two - Muscle ___________ and blood is pushed out of the heart a. ___________ contract and blood is pushed from atria through valves into the ventricles b. ____________ contract and blood is pushed through valves into the body 3. Each contraction of the muscle exerts a force on the blood Blood vessels When blood leaves the heart it travels through blood vessels. The blood vessel types are ______________, ___________________, and ____________________________. Blood flow The heart is two ____________. The first goes through the _________________ and the second goes through the __________________.: First loop – the pump to the lungs The blood going into the atrium of the right side of the heart has ______________ and is dark red. Then it is pumped through the right valve into the right ______________ and then out of the ventricle through the lungs where it picks up ____________ and drops off carbon dioxide. Blood returns to the left side of the heart Second loop – the pump to the body Blood going into the atrium of the left side of the heart has a lot of _____________ and is bright red. Then blood is pumped through the left ___________ into the left ventricle and then out into the ______________. The aorta branches into _________________ where _____________ is transferred from the blood to the body cells and carbon dioxide is removed Arteries – carry blood away from the heart The largest artery, carries blood out of the left side of the heart is called the _______________ and blood is carried to the heart muscles by the ______________ ____________________. They have ____________ muscular walls to absorb force of heart contractions. The ___________ is when the arteries are expanded by the blood being pushed through by the heart’s contractions. The ____________ _________ is controlled by the muscles in the walls of the arteries can expand and contract to allow more or less blood to flow through them Capillaries Materials are exchanged between the blood and body cells in the capillaries. Their ____________ are one cell thick and ____________, carbon dioxide, glucose can pass through easily. Veins – carry blood to the heart The largest veins in the body that carry blood to the right side of the heart are called the __________ ___________. The walls are ________________ than arteries and absorb less of the force of the heart’s contractions. Blood is also moved along veins with contractions of skeletal muscle around them and backward flow is prevented by ____________ along the insides of the walls Blood pressure It is caused by the ______________ of the heart pushing the blood with a ____________ which pushes the _____________. through the blood vessels. Blood pressure _____________ the farther you are from the heart Measuring blood pressure It is measured with _______________ in millimeters of Mercury. Two number are obtained, one when the heart is ________________ and the second is when the heart is _________________ Diseases 1___________________ 2. ___________________ 3. ___________________
