In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [ 1 ] [ 2 ] It includes the cardiovascular system , or vascular system , that consists of the heart and blood vessels (from Greek kardia meaning heart , and Latin vascula meaning vessels ).
The functional capacity of selectin is limited to leukocyte collaborations with vascular endothelium. There are three types of selectins found in humans; L-selectin, P-selectin and E-selectin. L-selectin deals with lymphocytes, monocytes and neutrophils, P-selectin deals with platelets and endothelium and E-selectin deals only with endothelium.
Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart muscle. Without enough blood supply , the heart is unable to work properly, especially under increased stress.
“Plaque buildup, or atherosclerosis, is the process that leads to blockages of the coronary arteries that supply the heart muscle. This is also called coronary artery disease. This is also ...
Foam cells are very small in size and can only be truly detected by examining a fatty plaque under a microscope after it is removed from the body, or more specifically from the heart. Detection usually involves the staining of sections of aortic sinus or artery with Oil Red O (ORO) followed by computer imaging and analysis; or from Nile Red ...
The inner dense plaque, also about 15–20 nm in length, contains the C-terminus end of desmoplakin and their attachment to keratin intermediate filaments. Desmoplakin is the most abundant part of the desmosome, [ 7 ] as it operates as the mediator between the cadherin proteins in the plasma membrane and the keratin filaments.
Immunotherapy may stimulate the host immune system to recognize and attack Aβ, or provide antibodies that either prevent plaque deposition or enhance clearance of plaques or Aβ oligomers. Oligomerization is a chemical process that converts individual molecules into a chain consisting of a finite number of molecules.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
