Krperprozesse

Semi-permeability refers to biomembrane that is selectively permeable to certain substances and cannot be passed by other substances. Semipermeability is the basis of osmosis and characterizes the cells of everyone

Insulin synthesis is induced in the organism when food is consumed. Insulin is a hormone that induces the cells to take up glucose through the cell membrane. A decrease in insulin synthesis leads to an increase in the level of sugar in the blood

The transmission of excitation from cell to cell - also from nerve cell to nerve cell - takes place via synapses. These are connection points between two nerve cells or between nerve cells and other tissue cells that are responsible for signal transmission

The protective acid mantle protects the skin from drying out as well as from micro- and noxious organisms through a hydrolipid film formed from sebum and sweat glands with a pH value of around 4.5. It is also known under the term fat film, whereby

The phenotype is the externally visible appearance of an organism with its various properties. Both the genetic makeup (genotype) and the environment have an influence on the expression of the phenotype.

The reaction norm corresponds to the genetically created range of possible variations of two phenotypes of the same genetic material. The final characteristic expression within this specified range depends on the respective external environmental influences

The sense of direction is not a single one of the six human sensory perceptions. Rather, it is composed of several of these sensory perceptions.

One is big, the other smaller. Asians are, on average, shorter than Europeans and women are shorter than men. Some people also suffer from tall or dwarf stature due to a genetic defect. So it can be said that the overall height

The body schema is the awareness of one's own body including its body-superficial demarcation from the environment. The concept is present from birth and therefore presumably genetic, but only develops fully after puberty. Next

Proton pump inhibitors belong to a group of drugs that are among the strongest sales drivers worldwide. The drugs inhibit the proton potassium pump, an enzyme that works in the parietal cells of the stomach as a proton pump for production and shutdown

Hemostasis is a term used to describe hemostasis. After an injury to a vessel, various physiological processes take place that bring the bleeding to a standstill.

After a bleeding injury, platelet aggregation is an important step in wound care and initiates recovery. It ensures that platelets are deposited within a few minutes, sticking to the damaged area and in this way

Immunological memory is made up of T and B memory cells and provides the immune system with specific information about certain pathogens. In this way, the immune system can make diseases more effective and faster after the initial infection

During silent celebrations, people become infected with a pathogen, but do not notice the infection because of the asymptomatic course. There is a silent and subclinical infection. This infection immunizes it against the specific pathogen

The medulla oblongata and the pons are the circulatory centers of the brain and constantly receive information on blood pressure and gas composition. From this, if necessary, measures to regulate the circulatory system are initiated, which is the central point

Piloerection (or goose bumps) is the reaction of the sympathetic nervous system in which small muscle groups contract. It is a reflex that has developed in the history of mammals and humans.

A short-term change in the membrane potential is called an action potential. Action potentials typically arise on the axon hill of a nerve cell and are the prerequisite for stimulus transmission.

According to training theory, the eccentric contraction is one of the 3 possible forms of muscle work alongside isometry and concentric. It plays an important role in movement sequences in everyday life and in sports.

The oral preparation phase is part of the swallowing process and makes a bite of food ready to swallow. This phase is followed by the oral transport phase, during which the swallowing reflex is triggered. Oral preparation disorders

The act of swallowing consists of a preparatory phase and three transport phases. The first phase corresponds to the oral transport phase of the food pulp, during which the swallowing reflex is triggered. Swallowing reflective disorders of the oral transport phase
