The kidneys are bilateral bean-shaped organs, reddish-brown in colour and located in the posterior abdomen. Their main function is to filter and excrete waste products from the blood. They are also responsible for water and electrolyte balance in the body.

Vasculature

The liver has a unique dual blood supply:

Anatomical Structure

Macroscopic

The liver is covered by a fibrous layer, known as Glisson’s capsule. It is comprised of a large right lobe and smaller left lobe. 

There are two further ‘accessory‘ lobes that arise from the right lobe, which are located on the visceral surface of liver:

As your heart pumps blood, four valves open and close to make sure blood flows in the correct direction. As they open and close, they make two sounds that create the sound of a heartbeat. The four valves are the aortic valve, mitral valve, pulmonary valve and tricuspid valve.

The base of the heart, the posterior part, is formed by both atria, but mainly the left. The anterior of the heart is formed mainly by the right atrium and ventricle, due to the twisting of the heart during development, which causes the left atrium and ventricle to lie posteriorly.

The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food

Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees. This results in the leg being shortened and the development of a limp. It may be congenital and is commonly caused by injury, such as a fracture.

The aortic arch is the segment of the aorta that helps distribute blood to the head and upper extremities via the brachiocephalic trunk, the left common carotid, and the left subclavian artery. The aortic arch also plays a role in blood pressure homeostasis via baroreceptors found within the walls of the aortic arch.
