Comprehensive Anatomy and Physiology Level 3 ============================================ This document provides a detailed overview of the main body systems covered at Level 3 in Health and Social Care. Each system includes its anatomy, function, common disorders (with causes, symptoms, and treatments), and relevant processes. Table of Contents ----------------- 1\. Cardiovascular System\ 2. Respiratory System\ 3. Digestive System\ 4. Musculoskeletal System\ 5. Nervous System (Control and Regulatory System)\ 6. Urinary System\ 7. Endocrine System\ 8. Sensory System\ 9. Blood Flow and Biological Processes\ 10. Diagrams 1. Cardiovascular System ------------------------ ### Anatomy The cardiovascular system includes the heart, blood vessels, and blood. It ensures the circulation of oxygen, nutrients, hormones, and waste products.\ - \*\*Heart\*\*: A muscular pump divided into four chambers:\ - Right Atrium and Right Ventricle: Pump deoxygenated blood to the lungs.\ - Left Atrium and Left Ventricle: Pump oxygenated blood to the body.\ - \*\*Blood Vessels\*\*: Include arteries (carry oxygen-rich blood), veins (carry oxygen-poor blood), and capillaries (site of exchange).\ - \*\*Blood\*\*: Contains red blood cells (oxygen transport), white blood cells (immunity), platelets (clotting), and plasma (fluid medium). ### Function \- Transport: Oxygen and nutrients to cells, and carbon dioxide and waste away.\ - Regulation: Maintains body temperature and pH balance.\ - Protection: Blood clots prevent excessive bleeding, and white blood cells fight infections. ### Disorders \- \*\*Coronary Artery Disease\*\*:\ - Cause: Narrowing of coronary arteries due to plaque buildup.\ - Symptoms: Chest pain, shortness of breath.\ - Treatment: Lifestyle changes, medications, or surgery (e.g., stents).\ - \*\*Heart Failure\*\*:\ - Cause: Weak heart muscle or high blood pressure.\ - Symptoms: Fatigue, swelling, shortness of breath.\ - Treatment: Medications (e.g., ACE inhibitors), lifestyle changes.\ - \*\*Arrhythmias\*\*:\ - Cause: Irregular electrical signals in the heart.\ - Symptoms: Palpitations, dizziness.\ - Treatment: Medications, pacemaker. ### Processes: Blood Flow 1\. Blood enters the \*\*right atrium\*\* from the body (via the vena cava).\ 2. It flows into the \*\*right ventricle\*\*, which pumps it to the lungs via the pulmonary artery.\ 3. Oxygenated blood returns to the \*\*left atrium\*\* via the pulmonary vein.\ 4. Blood flows into the \*\*left ventricle\*\*, which pumps it to the rest of the body through the aorta. Diagrams -------- Relevant diagrams for anatomy and processes (e.g., the heart, lungs, skeleton) will be added here.
