The correct answer is A. Public health improvements have contributed to world population growth.
Explanation
Public health is a discipline that is responsible for studying issues related to health improvement, disease control, and elimination. For this reason, it has been a determining factor for population growth in the last decades this can be explained as in previous centuries health services and disease control conditions were more limited due to the lack of study in these fields but today, there are instruments such as microscopes, tests, exams, among others to control and eliminate diseases. Also, the health conditions are more rigorous which reduces death rate and support population growth. So, the correct answer is A. Public health improvements have contributed to world population growth.

The aortic artery is divided into three parts: ascending aorta, aortic arch and descending aorta, the latter is divided into two parts: thoracic aorta and abdominal aorta; Depending on your location. The abdominal aorta is the most distal part of the aorta itself; It begins at the level of the diaphragm muscle, next to the lower edge of the body of T12 (the twelfth thoracic vertebra), and ends in the common iliac arteries, at the level of L4 (of the fourth lumbar vertebra) .An abdominal aortic aneurysm is a disease of the abdominal aorta.
The abdominal aorta continues the thoracic aorta at the level of the T12 vertebra, just in front of the spine and to the left of the inferior vena cava. Its path is medial, although it can take place in the right or left 1/3 of the vertebral bodies. The abdominal aorta measures between 15 and 18 cm in length and between 15 and 18 mm in caliber.
