The complexity of the human body is fascinating and unique. Even the smallest parts have their importance and justification. The following is a more detailed description of the earlobe in terms of its structure, function and potential problems. What is the earlobe? The human ear consists of the inner ear, middle ear and outer ear. … Earlobes: Structure, Function & Diseases
Bioprinters are a special type of 3D printer. Based on computer-controlled tissue engineering, they can produce tissues or bioarrays. In the future, it should be possible to produce organs and artificial living beings with their help. What is a bioprinter? Bioprinters are a special type of 3D printer. Bioprinters are technical devices for printing biological … Bioprinter: Function, Task & Diseases
Pulse oximetry uses a noninvasive, photometric method to determine the oxygen saturation of arterial blood by attaching a clip containing infrared light sources and a receiver to the patient’s skin. This clip determines the light absorption of the blood based on the fluoroscopy rate and, when converted to blood oxygen saturation, takes advantage of the … Pulse Oximetry: Treatment, Effects & Risks
The tricuspid valve is one of the four valves of the heart. It forms the valve between the right atrium and right ventricle and prevents blood from flowing back into the right atrium during contraction of the ventricle (systole). During relaxation (diastole), the tricuspid valve is open, allowing blood to flow from the right atrium … Tricuspid Valve: Structure, Function & Diseases
Definition When we talk about capillaries (hair vessels), we usually mean the blood capillaries, although we must not forget that there are also lymph capillaries. Blood capillaries are one of three types of vessels that can be distinguished in humans. There are the arteries that transport the blood away from the heart and the veins … Capillary
Structure of capillaries The structure of a capillary resembles a tube. The diameter of a capillary is about five to ten micrometers. Since the red blood cells (erythrocytes) that flow through the capillaries have a diameter of about seven micrometers, they must deform somewhat when they flow through the small blood vessels. This minimizes the … Structure of capillaries | Capillary
Functions of capillaries The function of the capillaries is mainly mass transfer. Depending on where the capillary network is located, nutrients, oxygen and metabolic end products are exchanged between the bloodstream and the tissue. Nutrients are supplied to the tissue, waste products are absorbed and carried away. Depending on the oxygen requirement of a particular … Functions of capillaries | Capillary
Capillary effect – what is that? Capillary effect is the term used to describe the behavior of liquids in which they are pulled upwards in a thin tube against gravity, for example. If you place a thin glass tube vertically in the water, you can observe how the water in the tube moves a little … Capillary effect – what is that? | Capillary
Physiology The blood vessels have the ability to increase or decrease the lumen of the vessel and thus modify the blood flow. To do this, they require the muscle layer of the tunica media, which tenses or relaxes the muscles through nerves supplied by vegetative nerves. This results in either one: since the arteries have … Physiology | Vessels
Synonyms Latin: vas Greek: angio Definition A vessel in a body is comparable to a tube that transports the body fluids lymph and blood. Depending on which fluid flows through this pipe system, a distinction is made between: All pipe systems in which other body fluids are transported are called “ductus” (lat. Ductus). This includes … Vessels
Definition The blood circulation consists of the heart and the blood vessels. The heart serves as a pump to pump the blood in the vessels through the body. For this purpose, the human body has a vascular system that branches out from the large vessels that originate directly from the heart to reach every part … The human blood circulation
Classification of the blood circulation The blood circulation is divided into a large circulation, the body circulation, and a small circulation, the lung circulation. In order to understand these two circuits, one must first understand the structure of the heart. The heart consists of two ventricles (ventricles) and two atria (atria). The left atrium and … Classification of the blood circulation | The human blood circulation
