The marginal flow of blood is the flow of blood in close proximity to the walls of the vessels. Especially in the smaller vessels, there is a plasmatic marginal current without leukocytes and erythrocytes, which has a significantly lower flow rate

The erythrocyte deformability or flexibility of the red blood cells enables the cells to pass through vessels with different lumens. In addition, erythrocytes change their shape depending on the temperature and flow rate of the blood, whereby

The Fåhraeus-Lindqvist effect is a blood flow phenomenon that is based on the fluidity of the erythrocytes and is related to the viscosity of the blood. The viscosity in vessels of the circulatory periphery with a narrow lumen is lower than

Neurological symptoms that arise due to damage to the pyramidal tract are called pyramidal tract signs. In total, there are more than twelve different pathological reflexes that are considered to be pyramidal signs. they deliver

The neurologist understands the Gordon reflex to be a pathological foot reflex. The crane-like toe movement is a pyramidal trajectory and indicates damage to the central motor neurons. Diseases such as multiple sclerosis come in as causes

The cough reflex is a process that occurs in the human body and cannot be suppressed at will. It is used, for example, when harmful elements have been deposited in the bronchi. With that go

The sucking reflex describes an innate reflex (unconditional in medicine) that is recorded in a number of mammals - humans are one of them. Usually, however, this reflex is unlearned during adolescence. At the

The eyelid closing reflex is a so-called polysynaptic external reflex that protects the eyes from the effects of foreign bodies and from dehydration. The reflex can be triggered by tactile, optical or acoustic stimuli, and can also be frightened

With abdominal breathing, also called abdominal breathing, breathing is largely determined by a contraction of the diaphragm. Abdominal breathing ventilates more of the lungs than chest breathing.

Basal metabolic rate is the daily energy consumption of people when they are completely at rest, on an empty stomach and at an ambient temperature of 28 degrees Celsius, at which the body does not provide any additional effort to maintain body temperature

The power metabolism is the total energy consumption of a person within 24 hours minus his basal metabolic rate, which corresponds to the maintenance requirement soberly at rest. The performance turnover is mainly dependent on activity and weight and

Oxygen transport is a physiological process in the organism in which oxygen is transported from the alveoli to all body cells. Complex physical and chemical processes take place that are closely related

Initiation is the first step and thus the preparation for translation, transcription and replication. Together, these phases essentially lead to gene expression. In pathophysiology, initiation also plays a role in relation to diseases

Termination is the final phase in DNA replication. It is preceded by initiation and elongation. An early termination of the replication can result in the expression of shortened proteins and thus a mutation.

In general, we divide our life into waking and sleeping phases. While we can consciously control the phases of activity in the wax state, this is not easily possible in the sleep phase. The brain controls with a variety of hormones

The amount of fluids that we drink every day has to be excreted through the urinary tract. The discharge from the body takes place by emptying the bladder - micturition.

The ATP synthase catalyzes the synthesis of ATP. It is a complex of hydrophobic and hydrophilic components.

Vascular constriction, also known as vasoconstriction, is the result of contractions of the tunica media. These contractions are either triggered by an increase in sympathetic tone or they are hormonally controlled. Pathological vascular obstruction

Enthusiasm is a trait that is viewed as desirable in the modern world. Enthusiastic people have an above-average interest in the things they do and are very enthusiastic about them

An interest is based on the cognitively strong participation in and the emotionally positive evaluation of certain activities, objects or people. Interests interact with attention and are generated in the brain, especially the frontal lobe
