The major components of the circulatory system include the cardiovascular system (blood vessels, the heart, and blood), and the lymphatic system (lymph, lymph vessels, and lymph nodes).The three types of blood vessels include arteries (carry blood away from the heart), veins (return blood to the heart), and capillaries (connecting the arteries and veins). The heart is responsible for the circulation of blood through blood vessels to the rest of the body. Blood (composed of WBC's, RBC's, platelets, and plasma) is responsible for carrying carbon to the lungs and delivering oxygen to cells. The lymphatic system and its various structures help assist the circulatory system through the drainage of proteins/excess fluids from the tissues and moving it back into the bloodstream.

What is the Purpose of the Circulatory System?

The main purpose of the circulatory system is the transportation of oxygen/nutrients/hormones to the cells and tissues of the body. This system is also responsible for the removal of waste products from the body such as carbon dioxide. The circulatory system works together with other body systems in order to maintain the body's proper homeostasis through supplying this blood/oxygen to all cells in the body.

Possible Disorders/Diseases of the Circulatory System- CAD

CAD (Coronary Artery Disease) : Coronary artery disease can occur when an abnormal amount of cholesterol deposits (also called plaque) into the arteries of the heart (coronary arteries). If the plaque continues to build up over a long period of time, the arteries of the heart can narrow resulting in the inability of the heart to receive an adequate amount of oxygen-rich blood. This process may also be known as atherosclerosis. CAD can cause an individual to experience various symptoms such as...

Agnia (chest pain and/or discomfort)
Lightheadedness
SOB
Nausea
Pain in the arm region

Diagnostic Test for CAD & Surgical/therapeutic Interventions

Diagnostic Test for CAD : One type of diagnostic test that may be performed when testing for coronary artery disease includes a blood test. A medical provider can then examine the individuals levels of triglycerides, cholesterol, sugar, lipoproteins, and proteins that may be a sign and increase risk of CAD.

Surgical/therapeutic Intervention for CAD : One type of surgical intervention for managing CAD includes an angioplasty. This procedure is used in order to reopen blocked coronary arteries and ultimately restore blood flow to the heart. During this procedure, a catheter is placed into a blood vessel and guided towards a blocked artery where a small balloon is inflated where narrowing has occurred, resulting in more space for blood flow.

Possible Disorders/Diseases of the Circulatory System- Myocardial Infarction (MI)

Myocardial Infarction (Heart Attack) : A heart attack can occur in an individual when there is a blockage of blood flow leading to the heart. Most often a blockage occurs due to an abnormal build up cholesterol, fat, and other substances within the coronary arteries. CAD is the most common cause of heart attacks. Symptoms of a heart attack can include...

Angina
Burning sensation in the chest
Fatigue
Lightheadedness
Arm tightness
Neck tightness

Possible Disorders/Diseases of the Circulatory System- Hypertension

allisonja04_ — 2023-11-27 20:31:27 UTC

Hypertension (High blood pressure) : Hypertension is a condition in which the force of blood moving through blood vessels is too high. If hypertension is left untreated, it can ultimately lead to other more serious health conditions such as a stroke or heart disease. This condition is most often caused by unhealthy lifestyle decisions, lack of physical activity, genetics, etc.
