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.

The trachea divides into two bronchi, one for each lung, and the air then enters the lungs , where oxygen is absorbed into the bloodstream and carbon dioxide is removed.

Explanation
The ribcage, also known as the thoracic cage . It is a bony structure that encloses and protects the lungs, heart, and other organs in the thoracic cavity. It is composed of 24 ribs , the sternum (breastbone) , and the 12 thoracic vertebrae.

Explanation
Lungs are two soft, spongy, large balloon-like organs located in the chest cavity, specifically in the thoracic cavity. They are responsible for exchanging oxygen and carbon dioxide through the process of respiration.

Explanation
The breathing centre of human body is lungs . Lungs are two soft spongy large balloon like organ located in the chest. The delicate lungs are protected by a cage of bones. This cage is called the ribcage.
