Hypoxaemia. Blood with higher oxygen content appears bright red. Specialty. Pulmonology. Hypoxemia is an abnormally low level of oxygen in the blood. [1][2] More specifically, it is oxygen deficiency in arterial blood. [3] Hypoxemia has many causes, and often causes hypoxia as the blood is not supplying enough oxygen to the tissues of the body.
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. [ 1 ] Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. [ 2 ] Although hypoxia is often a pathological condition, variations in arterial oxygen ...
The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [1][2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and from Latin vascula ...
Liquid breathing. Liquid breathing is a form of respiration in which a normally air -breathing organism breathes an oxygen -rich liquid which is capable of CO 2 gas exchange (such as a perfluorocarbon). [ 1 ] The liquid involved requires certain physical properties, such as respiratory gas solubility, density, viscosity, vapor pressure and ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
A life-support system is the combination of equipment that allows survival in an environment or situation that would not support that life in its absence. It is generally applied to systems supporting human life in situations where the outside environment is hostile, such as outer space or underwater, or medical situations where the health of ...
[108] [109] Blood or air with a high oxygen content is shown in red; oxygen-poor air or blood is shown in various shades of purple-blue. The lungs of birds are relatively small, but are connected to 8 or 9 air sacs that extend through much of the body, and are in turn connected to air spaces within the bones. On inhalation, air travels through ...
The heart is a muscular organ found in most animals. This organ pumps blood through the blood vessels. [ 1 ] Heart and blood vessels together make the circulatory system. [ 2 ] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [ 3 ]
