Explanation
The ribcage, which consists of the ribs and sternum . It forms a protective cage around the thoracic cavity, shielding the vital organs within , including the heart and lungs.

Explanation
Smoking is the leading cause of lung cancer. It is responsible for about 80-90% of all lung cancer deaths.

Explanation
Lung cancer is a disorder that occurs when cell division in the respiratory tract becomes uncontrolled. It leading to the formation of abnormal cells that can cause tumors and cysts.

Explanation
Asthma and lung cancer are two main disorders that affect the lungs. Asthma : a chronic inflammatory disease that causes recurring episodes of wheezing, coughing, chest tightness, and shortness of breath due to the inflammation of the airways. Lung Cancer : a disease caused by the abnormal growth of cells.

Explanation
The lungs are responsible for exchanging oxygen and carbon dioxide through the process of respiration. Oxygen from the air we breathe in is absorbed into the bloodstream. Carbon dioxide, a waste product, is removed from the bloodstream and exhaled out.

Explanation
The diseases you mentioned are all related to the heart and cardiovascular system : High blood pressure (hypertension) Hardening of the blood vessels (atherosclerosis) Chest pain (angina) Heart attacks (myocardial infarction) Strokes (cerebrovascular accident)

Explanation
The heart is located in the thoracic cavity, slightly to the left of the center of the chest , behind the breastbone (sternum).

Explanation
Blood vessels , which include arteries, veins, and capillaries. It form a network that carries blood throughout the body. It supplying oxygen and nutrients to tissues and organs.

Explanation
The heart is the pumping station of the human body. It is responsible for pumping blood throughout the body. It supplying oxygen and nutrients to tissues and organs.

Explanation
Indigestion ( also known as dyspepsia ) is a common condition characterized by discomfort or pain in the upper abdomen , caused by: Eating too much or too quickly Consuming spicy or fatty foods Drinking alcohol or caffeine Stress

Explanation
Asthma is a common breathing disorder that causes difficulty in breathing due to swollen air passages. The airways become inflamed, and the muscles around them constrict, making it hard to breathe.
