The heart and circulatory system work together to make the cardiovascular system. Both of these systems deliver blood to the body’s tissues. As the heart beats, blood is sent throughout the body, carrying oxygen and nutrients.
In the Circulatory system the organs and vessels work together to work with the flow of blood, nutrients, oxygen, other gases, and hormones that go to and from cells. The Circulatory system is important because it helps the body fight diseases and to maintain stable internal environment.

- right atrium-receives blood from the body systems via the vena cavae
- right ventricle-pumps blood to the lungs
- left atrium-receives blood from the lungs
- left ventricle-pumps blood to the body systems via the aorta
ANGINA: Ischemia, reduced blood supply to the heart, creates pain in the chest. Less blood means less oxygen being carried through the body. Atherosclerosis, narrowing of the blood vessels that supply the heart, causes angina. Some symptoms are pain in the chest that can spread to the left arm, shoulder or jaw. Angina attack comes with shortness of breath and sweating. The exact areas that are affected by angina differ by male or female. CORONARY ARTERY DISEASE: Another name for Coronary artery disease is ischemic heart disease. Atherosclerosis, the narrowing of the blood vessels that supply the heart, cause it. It can be the cause of heart attacks and angina. Coronary artery disease is the most common form of heart disease.
ANEURYSMS: Aneurysms may become life threatening if they rupture because they can get bigger over time. It is the wall of a blood vessel being weak or having a bulge. They occur in arteries so it can happen anywhere in the body, especially the abdominal aorta and the arteries at the base of the brain. Two reasons why it can occur are because of high blood pressure or the blood vessel wall having a weak spot.
HYPERTENSION (HTN): Hypertension means having high blood pressure. Blood pressure is measured as the heart pumps blood through the body and the force that is used to go against the walls of arteries. The two numbers used to see the blood pressure is systolic over diastolic using millimeters over mercury (mmHG). Symptoms differ from men and woman. Many times woman have it and don’t know.
VULVAR HEART DISEASE: Vulvular heart disease can be something someone is born with or it may be caused from: damage to the valves by rheumatic fever, infections connective tissue disorders, and cancer treatments. The heart valves are very important because they make sure the blood goes to its correct location. When something happens to the valves like it narrows (Stenosis), leaks (Regurgitation) or it doesn't close correctly (Prolapsed), the blood flow can be affected.
ATHEROSCLEROSIS: Atherosclerosis is when the flow of blood is restricted because of plaques, fatty deposits. When this happens, the walls of the arteries become thick and stiff because of all the fat that has been collected. It can happen in arteries throughout the body and can lead to heart attack and stroke. Nicotine hardens the arteries.
Congestive Heart Failure (CHF): . Congestive Heart Failure is when the heart isn’t delivering the oxygen rich blood that the body needs. It can be caused by the following:
1. Diseases that weaken the heart muscle
2. Diseases that cause stiffening of the heart muscles
3. Diseases that increase oxygen demand by the body tissue beyond the capability of the heart to deliver adequate oxygen-rich blood.
Slowly, the untreated, and worsening congestive heart failure will spread and affect every organ in the body.
Myocardial Infarction(MI): Coronary artery disease leads to Myocardial Infarction. It is the lack of oxygen supplied from the heart to the tissue. Since the tissues are getting less blood, the tissue begin to die off. When it gets to this stage oxygen flow to the heart has stopped. Tissue death shows up in blood work.
Endocarditis: Endocarditis is an infection of the endocardium, the inner lining of the heart. When bacteria goes through the bloodstream and attaches itself to damaged areas in your heart. If nothing is done to stop it, endocarditis can destroy the heart valves and can put a person’s life in danger.
Atrial fibrillation: Atrial fibrillation is the most common arrhythmia. Arrhythmia is a problem with the rhythm of the heart. It can either be that the rhythm is too fast, too slow or irregular. Atrial fibrillation occurs when the atria, two upper chamber of the heart, contract very fast and irregularly. It comes from disorganized
Anemia: When the blood does not have enough healthy red blood cells or hemoglobin, Anemia occurs. When the body does not get enough red blood cells or they are abnormal the cells in the body would not get sufficient oxygen. Organs need oxygen to function, so it causes the body to have fatigue.
