Bacteria infecting the mouth can enter the blood through small cuts resulting from normal brushing and flossing. Why would these bacteria reach the right atrioventricular valve before the other heart valves?
To tell:
The reason for the bacteria which reaches first to the right atrioventricular valve before any other heart valves.
Introduction:
The blood is normally microbes free; that is, it does not contain any microbes like bacteria, virus, fungi, and parasites. However, small brushing and abrasions provide an entrance for the microbes like bacteria to enter the bloodstream. The presence of bacteria in the bloodstream is known as “bacteremia”. The example of some bacteria that may enter the bloodstream is Klebsiella pneumonia, Staphylococcus aureus, Clostridium tetani, and so on.
Explanation of Solution
Bacteria from the mouth enter into to the blood. The blood carries these bacteria to the superior vena cava through which blood enters into the heart. The vena cava then delivered the blood to the right atrium and then into the right ventricle. Before entering the right ventricle it must pass a valve. The valve that is present between the right atrium and right ventricle is called the right atrioventricular valve, so it will be the first valve in which the bacteria will reach before any other heart valve.
The atrioventricular is known to be the first valve for the bacteria to enter when compared with another valve.
