Lesson Lesson 22Care and Problems of the Cardiovascular System

If heart disease runs in your family, you need to make careful choices now to promote a lifetime of cardiovascular health.

Lesson Lesson 22Lesson Objectives

• Discuss health promotion and prevention of cardiovascular disease

• Examine the effects of health behaviors on the cardiovascular and lymphatic systems

• Identify warning signs that prompt individuals to seek health care

In this lesson, you will learn to:

Lesson Lesson 22Healthful Habits

Health Behaviors and the Cardiovascular and Lymphatic Systems

• Follow a well-balanced diet that is low in saturated fats, cholesterol, and salt.

• Maintain a healthy weight to reduce stress on the heart, blood vessels, and lymph vessels.

• Participate in regular aerobic exercise for at least 30 minutes three to four times per week.

• Avoid the use of tobacco products and exposure to secondhand tobacco smoke.

• Avoid illegal drugs, including stimulants, marijuana, and ecstasy (MDMA).

Lesson Lesson 22Blood Pressure

• Blood pressure is an indicator of cardiovascular health.

• Chronic high blood pressure is an early indicator of several cardiovascular system problems and should prompt individuals of all ages to seek health care.

• Prevention of high blood pressure includes staying physically active, avoiding tobacco and drugs, and following a healthful eating plan that is low in salt.

Cardiovascular System Problems

Lesson Lesson 22Congenital Heart Defects

• Most congenital heart defects require medication and possibly surgery to repair the affected portion of the heart.

• Use of alcohol and other drugs during pregnancy is associated with heart defects in newborns.

• Certain infections during pregnancy can also increase the risk of congenital heart defects.

• Some cases may be hereditary.


Lesson Lesson 22Cardiovascular Disease

• Cardiovascular disease (CVD) is actually a group of diseasesof the cardiovascular system that includes hypertension, heart disease, and stroke.

• According to the Centers for Disease Control and Prevention, about 95,000 Americans die of CVD each year.

• Many of these diseases are associated with lifestyle behaviors.

• Early detection is important for reducing the risk for CVD.


Lesson Lesson 22Heart Murmur

• Heart murmurs are abnormal sounds that are made as blood flows through the heart.

• Some heart murmurs may be very slight and disappear without treatment.

• Other murmurs can be an indication of problems in the heart, such as the valve between the left atrium and ventricle not closing properly, and may require surgery.


Lesson Lesson 22Varicose Veins

• Varicose veins form if valves in the veins do not close tightly enough to prevent backflow of blood.

• Varicose veins become enlarged and can be painful.

• Weakened valves can be the result of a congenital defect or natural aging.

• Treatment includes reducing standing time, exercise, elevating legs when sleeping, and in severe cases, surgery to remove the affected vein.


Lesson Lesson 22Anemia

• Anemia can result from low numbers of red blood cells or from low concentrations of hemoglobin in the blood.

• The most common cause of anemia is iron deficiency, which

can be avoided by eating foods high in iron.

• Taking an iron supplement also may be recommended by a medical professional.


Lesson Lesson 22Leukemia

• The abnormal white blood cells cannot function properly, making the leukemia patient very susceptible to infection.

• Because all blood cells are produced in the bone marrow, the uncontrolled production of white blood cells can hinder the production of red blood cells and platelets.

• The result is infection, severe anemia, or uncontrolled bleeding.

• Chemotherapy and radiation are among the treatment options.


Lesson Lesson 22Hemophilia

• Hemophilia is an inherited disorder in which the blood does not clot properly.

• This may cause uncontrolled bleeding that can occur spontaneously or as a result of injury.

• Bleeding can take place internally in muscles, tissues of the digestive and urinary tract, and the joints.

• It may also occur externally as a result of injury or surgery.

• Treatment for hemophilia includes injections that introduce the missing clotting factors into the blood.


Lesson Lesson 22Some Common Problems with the Lymphatic System

Lymphatic System Problems

Immune Deficiency

Hodgkin’s Disease

Tonsillitis

Lesson Lesson 22Immune Deficiency

• Immune deficiencies occur when the immune system can no longer protect against infection.

• Some deficiencies may be congenital, and others can be caused by HIV.

• A weakened immune system may be the result of natural aging or a side effect of chemotherapy.


Lesson Lesson 22Hodgkin’s Disease

• Hodgkin’s disease, or Hodgkin’s lymphoma, is found in lymph nodes and the spleen.

• Early detection and treatment, as in all types of cancer, is essential for recovery.

• Treatment may include removal of lymph nodes, radiation, and chemotherapy.


Lesson Lesson 22Tonsillitis

• Tonsils help reduce the number of pathogens entering the body through the respiratory system.

• Infected tonsils, or tonsillitis, is most often treated with antibiotics.

• Chronic cases may call for surgical removal of the tonsils.
