Rotary gate valves consist of a valve defining access to the inlet and outlet, a knife gate, a small tree with a longitudinal axis, and a gate with a first end connected to the drive shaft for GI use. Vertical to this longitudinal axis....
The Layers of the Heart Wall The heart wall is composed ofconnective tissue,endothelium, andcardiac muscle. It is the cardiac muscle that enables the heart to contract and allows for the synchronization of theheartbeat. The heart wall is divided into three layers: epicardium, myocardium, and en...
Blood passes from the left atrium into the left ventricle, from where it is pumped out of the heart into the aorta, the body’s largest artery. Smaller arteries that branch off the aorta distribute blood to various parts of the body. Four valves within the heart help prevent blood from ...

As seen in the diagram, the human heart has two atria and two ventricles. The myocardium of the ventricular walls is thicker than that of the atria. The valves are basically flaps of connective tissue anchored in the heart’s dense connective tissue, or cardiac skeleton, concentrated in the ...

All of the approximately 50 valves studied from 20 rats had a bileaflet structure, with a buttress formed at each side of the valve by the fusion of opposing leaflets. This valve structure would allow the valve to close without inversion. There is no evidence for active smooth muscle action ...

The cardiovascular system (CVS) is made up of the heart, blood vessels, and blood. The fundamental function of CVS is to transport substances to and from all parts of the body. The heart is the major pumping organ, pressurizing blood for circulation thro
