Describe the roles and differences between arteries, veins, and capillaries, explaining how each type of blood vessel functions within the circulatory system.

State the normal resting blood pressure ranges for systolic and diastolic blood pressure. Define what blood pressure levels are considered healthy and what levels indicate hypertension or hypotension.

Coronary heart disease (CHD) is a leading cause of death worldwide, and understanding its risk factors is crucial for prevention. These risk factors can be categorized into controllable and uncontrollable: while we cannot change certain factors like age or genetics, we can manage others such as lifestyle choices. Among the controllable risk factors, smoking stands out as particularly dangerous due to its direct impact on arterial walls and its promotion of atherosclerosis, the build-up of fatty deposits that narrow and harden the coronary arteries. Smoking accelerates the development of plaque, increases blood clot formation, and reduces oxygen delivery to the heart, thereby substantially heightening the risk of heart attack.

Another significant controllable risk factor is hypertension, or high blood pressure. Elevated blood pressure strains the heart, damages arterial walls, and facilitates plaque accumulation. Dietary habits rich in saturated fats, trans fats, and excessive salt contribute to hypertension, making lifestyle modifications like reducing salt intake, increasing physical activity, and balancing diet essential preventive measures. Physical inactivity itself is also a risk factor, as lack of exercise leads to obesity, poor lipid profiles, and increased blood pressure. Regular exercise helps control weight, improve circulation, and lower blood pressure, thus decreasing the risk of CHD. Moreover, poor dietary choices, such as high intake of processed foods and sugars, can lead to obesity and dyslipidemia, further exacerbating cardiovascular risks.

Conversely, uncontrollable risk factors include age, as the risk of CHD increases significantly with age due to the gradual accumulation of arterial damage. Gender also plays a role, with men generally at higher risk at younger ages, although postmenopausal women experience increased risk owing to hormonal changes. Family history is another uncontrollable factor; individuals with a family history of heart disease are at greater risk regardless of lifestyle. These factors highlight the importance of early screening and intervention in high-risk populations to mitigate potential adverse outcomes.

Defining key cardiovascular terms enhances our understanding of disease processes. Angina Pectoris describes chest pain caused by reduced blood flow to the heart muscle, often a precursor to more severe events such as heart attacks. Ischemia refers to insufficient blood supply to tissues, leading to oxygen deprivation, which can cause tissue damage if prolonged. Atherosclerosis is the process of fatty plaque buildup within arterial walls, narrowing arteries and impeding blood flow. Tachycardia indicates an abnormally fast heart rate, while bradycardia refers to a slower-than-normal heart rate. Arrhythmia encompasses irregular heartbeats that can disturb normal heart function. A thrombus is a blood clot that forms within vessels, potentially causing blockages; if it dislodges, it becomes an embolus, traveling through the bloodstream and risking obstruction elsewhere. An aneurysm is an abnormal dilation of a blood vessel, which may rupture and cause life-threatening bleeding.

The flow of blood through the heart and lungs begins in the right atrium, where deoxygenated blood from the body collects. It then passes through the tricuspid valve into the right ventricle, which pumps it through the pulmonary arteries to the lungs for oxygenation. Oxygen-rich blood returns via pulmonary veins into the left atrium, flows through the mitral valve into the left ventricle, and is subsequently pumped through the aorta to the rest of the body, completing the circulation cycle. Proper functioning of this flow is vital for oxygen delivery and waste removal.

Signs and symptoms of a heart attack include chest pain or discomfort, shortness of breath, pain radiating to the arm, neck, or jaw, and nausea or dizziness. Recognizing these symptoms promptly is essential for seeking immediate medical attention to reduce damage to the heart muscle and improve survival outcomes.

The roles of blood vessels are distinct yet interconnected. Arteries carry oxygen-rich blood away from the heart to tissues, characterized by thick, elastic walls to withstand high pressure. Veins return deoxygenated blood from tissues back to the heart, possessing valves to prevent backflow. Capillaries are tiny vessels where exchange of gases, nutrients, and waste products occurs between blood and tissues, due to their thin walls that facilitate diffusion.

Normal resting blood pressure ranges are approximately 120/80 mmHg, with systolic pressure (the top number) indicating arterial pressure during heart contraction, and diastolic pressure (the bottom number) reflecting pressure during relaxation. Blood pressure readings consistently above 130/80 mmHg are classified as hypertension, increasing cardiovascular risk, while readings below 90/60 mmHg may denote hypotension, which can cause dizziness and fainting.

Reducing cancer risk involves various healthy behaviors. These include using sunscreen to prevent skin damage, avoiding tobacco products to reduce lung and other cancers, maintaining a healthy weight through diet and exercise, limiting alcohol consumption, eating a diet rich in fruits and vegetables, engaging in regular physical activity, practicing safe sex to prevent HPV-related cancers, avoiding exposure to known carcinogens, getting vaccinated against cancer-related viruses, undergoing regular screening tests, and ensuring adequate sleep and stress management.

The “ABCD” rules assist in skin cancer identification: Asymmetry (one half of the mole does not match the other), Border irregularity (edges are ragged or blurred), Color changes (varied shades of brown, black, or other colors), and Diameter (moles larger than 6mm). These criteria help distinguish benign moles from malignant melanoma. Benign tumors are non-cancerous, localized growths that do not invade nearby tissues or metastasize, while malignant tumors are cancerous, capable of invading tissues, and spreading throughout the body, posing serious health risks.
