Cardiology Study Notes

Introduction The redox or redox reactions are reactions in which there is a variation in the oxidation number ( n. O. ) Of ions or atoms. The chemical species that oxidizes yields electrons and increases the oxidation number. The chemical species that is reduced acquires those electrons, decreasing the oxidation number. Obviously the chemical species that oxidizes acts as a reducing agent while, on the contrary, the one that … Read more

Mechanical Mitral Valve. They are made of materials such as plastic , metal and the latest models consist of a small pyrolytic carbon cylinder. The pyrolytic carbon is graphite bombarded with atoms of carbon at high temperatures, a material almost as hard as diamond . It is very little thrombogenic (not very likely to produce clots or strokes ) and begins to show wear after an equivalent of 80 years of operation. However, over time, … Read more

ingle ventricle. It is a congenital heart disease characterized by the existence of a dominant ventricular cavity, endowed with an entrance sinus and a well-developed trabeculated portion with which the two atria fully connect (double entry, common atrioventricular valve or atresia of an atrioventricular valve) or dominant ( more than 50% crowding of one of the atrioventricular valves). … Read more

Left ventricle. It is the portion of the heart with the greatest amount of muscle tissue because the left ventricle is the one that propels the blood to the aortic artery , which carries blood to most of the body . The valve that connects the left ventricle to the aortic artery is called the aortic valve .

Right Ventricle The right ventricle is one of the four chambers (two cardiac atria and two ventricles) of the heart. The right ventricle receives non-oxygenated blood from the right atrium through the tricuspid valve and pumps it out of the heart through the pulmonary artery. Summary [ hide ] 1 Description 2 References 3 Internal links 4 Sources Description It is triangular and spheroidal in … Read more

Ventricle . In animal anatomy , it refers to each of the lower chambers of the heart . The heart of mammals, including humans, has two ventricles, while the heart of other animals, such as fish and amphibians, has a single ventricle. The ventricles receive blood from the upper chambers on the same side of the heart, the atria. Each ventricle contracts during systole, which is the period … Read more
