The most common diseases of the aorta include atherosclerosis and the aortic aneurysm. In atherosclerosis, deposits form in the vessel wall, which reduce their elasticity and thus secondary to the aortic aneurysm, a tear in the aorta
The sternocleidomastoid muscle, also known as the big head turner or head nod, connects the sternum with the occiput. He can turn his head to one side when contracting on one side and nod when contracting on both sides.
The lymphatic organs include the organs in which the lymphocytes, the main actors of the immune system, reside. The primary lymphatic organs are the bone marrow and the thymus, where the lymphocytes are formed and shaped. Second
The lymph vessels run through the whole body and transport the lymph, i.e. tissue fluid, back to the blood vessels. The intermediate lymph nodes filter the lymph by eliminating pathogens. The lymph nodes
Striated muscles or skeletal muscles are the muscles of the body that can be controlled at will, such as the muscles of the legs. Due to their microscopic structure, the muscle fibers look striped. The skeletal muscles over a

Alpha-1-antitrypsin is a so-called protease inhibitor and is produced in the liver. If the value of this substance is increased, this indicates an acute change in the body, the cause of which should be found. Low values are mostly genetic
The heart is made up of different layers. The innermost layer is the endocardium. Since the endocardium is a very smooth surface, it promotes proper blood flow in the heart and prevents thrombus formation. Inflammation of the
The AV node (nodulus atrioventricularis) lies below the sinus node in Koch’s triangle. It consists of specialized heart muscle cells that generate an electrical signal that causes the heart to contract. If the sinus node fails, takes over
The outermost layer of the heart wall is the epicardium (outer skin of the heart). It produces the fluid between the heart and the surrounding pericardium and thus reduces friction. Inflammation (epicarditis) can cause too much fluid in the pericardium
The human set of teeth in healthy, adult humans contains 32 teeth. A newborn has no teeth yet, from the 6th month of life the milk teeth grow out, which fall out in childhood up to puberty and are replaced by the permanent teeth

The lungs are hollow organs which, by inhaling and exhaling up to 4.5 liters of air, ensure that the organism is supplied with oxygen and that carbon dioxide is excreted. It has two wings, lies in the rib cage and so is made by the ribs
The superior and inferior vena cava collect the body's venous, deoxygenated blood and direct it back to the heart. From there it goes back to the lungs, where it is enriched with oxygen before it is pumped back into the body's circulation.

The esophagus is a muscle tube that connects the oral cavity and the stomach and is mainly responsible for transporting food after ingestion. There are a number of internal and surgical diseases
The right atrium is one of the four interior spaces of the heart that is included in the great circulation. The blood flows into it via the vena cava and is forwarded to the right ventricle. It also includes the sinus node and the AV node as
The larynx (larynx) connects the throat (pharynx) with the windpipe (trachea). It is mainly used for breathing and voice training. In addition, the larynx is involved in the swallowing process and acts as a valve to prevent food and drinks from entering
The pulmonary circulation is also referred to as the "small circulation" and supplies venous, i.e. oxygen-poor blood from the heart to the lungs in order to enrich it with oxygen again and thus return it to the heart, from where it enters the body or
The tricuspid valve is located between the right ventricle and the right atrium. It belongs to the sail flaps and consists of a total of three sails. The tricuspid valve is significantly less affected by valve defects than the other heart valves
