What are the 12 pairs of bones that surround the heart and lungs?
144833
They are the ribs.  Though technically only 7 of them go completely around to surround the heart and lungs.

24 ribs.  12 pairs of ribs.  There are some in rare cases that have one more pair or one less pair.  However 12 pair is the norm.\n\nAnd sorry all those creationist types out there.  Men and women have equal number of ribs.

At birth the human body has about 350 bones, but by the time adulthood rolls around, some of our bones have fused together to give us a total of 206 bones in our body!\n\nHere is the breakdown:\n\nThe adult skeleton consists of 206 bones . . .\n\n- 28 skull bones (8 cranial, 14 facial, and 6 ear bones);\n\n- the horseshoe-shaped hyoid bone of the neck;\n\n- 26 vertebrae (7 cervical or neck, 12 thorax, 5 lumbar or loins, the sacrum which is five fused vertebrae, and the coccyx, our vestigial tail, which is four fused vertebrae);\n\n- 24 ribs plus the sternum or breastbone; the shoulder girdle (2 clavicles, the most frequently fractured bone in the body, and 2 scapulae);\n\n- the pelvic girdle (2 fused bones);\n\n- 30 bones in our arms and legs (a total of 120);\n\n- There are also a few partial bones, ranging from 8-18 in number, which are related to joints.

The normal amount is 206 bones, however, the number varies between people due to sesamoid bones (bones that grow in tendons that experience hight stress).  The patella is a sesmoid bone.  There are also a varied number of bone fragments in the sutures of the skull.

In the human body, the heart is normally situated slightly to the left of the middle of the thorax, underneath the sternum (breastbone). It is enclosed by a sac known as the pericardium and is surrounded by the lungs. The apex is the blunt point at the base of the heart. A stethoscope can be placed directly over the apex and count the beats. In normal adults, its mass is 250-350 g, but extremely diseased hearts can be up to 1000 g in mass. It consists of four chambers, the two upper atria (singular: atrium) and the two lower ventricles.\n\nA septum divides the right atrium and ventricle from the left atrium and ventricle, preventing blood from passing between them. Valves between the atria and ventricles (atrioventricular valves) maintain coordinated unidirectional flow of blood from the atria to the ventricles.The ventricular systole consists of the contraction of the ventricles and flow of blood into the circulatory system. Again, once all the blood empties from the ventricles, the pulmonary and aortic semilunar valves close. Finally complete cardiac diastole involves relaxation of the atria and ventricles in preparation for refilling with circulating blood.\n\nThe function of the right side of the heart (see right heart) is to collect deoxygenated blood from the body and pump it into the lungs so that carbon dioxide can be dropped off and oxygen picked up. This happens through a process called diffusion. The left side (see left heart) collects oxygenated blood from the lungs and pumps it out to the body. On both sides, the lower ventricles are thicker than the upper atria.\n\nOxygen-depleted or deoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part. The blood then passes through the tricuspid valve to the right ventricle. The right ventricle pumps the deoxygenated blood to the lungs, through the pulmonary artery. In the lungs gaseous exchange takes places and the blood releases carbon dioxide into the lung cavity and picks up oxygen. The oxygenated blood then flows through pulmonary veins to the left atrium. From the left atrium this newly oxygenated blood passes through the mitral valve (also called the bicuspid valve) to enter the left ventricle. The left ventricle then pumps the blood through the aorta to the entire body. Even the lungs take some of the blood supply from the aorta via bronchial arteries.\n\nThe left ventricle is much more muscular (1.3 - 1.5 cm thick) than the right (0.3 - 0.5 cm thick) as it has to pump blood around the entire body, which involves exerting a considerable force to overcome the vascular pressure. As the right ventricle needs to pump blood only to the lungs, it requires less muscle.\n\nEven though the ventricles lie below the atria, the two vessels through which the blood exits the heart (the pulmonary artery and the aorta) leave the heart at its top side.\n\nThe contractile nature of the heart is due to the presence of cardiac muscle in its wall which can work continuously without fatigue. The heart wall is made of three distinct layers. The first is the outer epicardium which is composed of a layer of flattened epithelial cells and connective tissue. Beneath this is a much thicker myocardium made up of cardiac muscle. The endocardium is a further layer of flattened epithelial cells and connective tissue which lines the chambers of the heart.\n\nThe blood supply to the heart itself is supplied by the left and right coronary arteries, which branch off from the aorta.

The human head contains 22 bones, consisting the cranium and the facial bones. The cranium is formed by 8 bones: the frontal bone, two parietal bones, two temporal bones, the occipital bone in the back, the ethmoid bone behind the nose, and the sphenoid bone. The face consists of 14 bones including the maxilla (upper jaw) and mandible (lower jaw).

First, the bones are the structural support for muscles, nerves, blood and lymph circulation systems, as well has holding the various organs and glands in place.\n\nMay I recommend a few?

Head, thorax, abdomen. If you are in med school, this might not be the best place to get the answer.

The human skeleton is made of individual or joined bones (such as the skull), supported and supplemented by a structure of ligaments, tendons, muscles, cartilage and other organs.\n\nThe skeleton is not unchanging; it changes composition over a lifespan. Early in gestation, a fetus has no hard skeleton; bones form gradually during nine months in the womb. At birth, all bones will have formed, but a newborn baby has more bones than an adult. On average, an adult human has 206 bones (according to Gray's Anatomy, but the number can vary slightly from individual to individual), but a baby is born with approximately 300 bones. The difference comes from a number of small bones that fuse together during growth, such as the sacrum and coccyx of the vertebral column. An infant is born with pockets of cartilage between particular bones to allow further growth. The sacrum (the bone at the base of the spine) consists of five bones which are separated at birth but fuse together into a solid structure in later years. Growing is usually completed between ages 13 and 18, at which point the bones have no pockets of cartilage left to allow more growth.\n\nNot all bones are interconnected directly. There are 6 bones, the auditory ossicles (three on each side), in the middle ear that articulate only with each other. Another bone, the hyoid bone in the neck, does not touch any other bones in the body, and is supported by muscles and ligaments; it serves as the point of attachment for the tongue.Also some of the ribs called the floating ribs only hang by muscle and are not attached to the spine.\n\nThe longest and heaviest bone in the body is the femur and the smallest is the stapes bone in the middle ear. In an adult, the skeleton comprises around 20% of the total body weight.\n\nBones of the Head\n\n    * frontal bone\n    * mandible\n    * maxilla\n    * occiptal bone\n    * parietal bone\n    * temporal bone\n    * zygomatic bone \n\nBones of the Neck and Chest\n\n    * acromion\n    * atlas\n    * cervical vertebra\n    * clavicle\n    * false rib\n    * floating rib\n    * scapula\n    * spine of scapula\n    * sternum\n    * thoracic vertebra\n    * vertibral column \n\nBones of the Abdomen\n\n    * coccyx\n    * ilium\n    * ischium\n    * lumbar vertebra\n    * sacrum\n    * vertibral column \n\nBones of the Arm\n\n    * carpus (carpals)\n    * epicondyle\n    * epitrochlea\n    * head of humerus\n    * humerus\n    * metacarpus (metacarpals)\n    * olecranon\n    * phalanx (phalanges)\n    * radius\n    * ulna \n\nBones of the Leg\n\n    * calcaneus\n    * condyle of femur\n    * femur\n    * fibula\n    * head of femur\n    * metatarsus (metatarsals)\n    * neck of femur\n    * patella\n    * phalanx (phalanges)\n    * talus\n    * tarsus (tarsals)\n    * tibia

The answer is 206 \n\nThe "adult" human body has 206 bones. At the time of birth a child has 300 bones but these bones fuse with each other as the child grows up and at adulthood the figure drops to 206.
