Answer: A. endocarditis
Explanation:
Endocarditis is the inflammatory process of the endocardium, especially that located in the heart valves. There are several factors causing endocarditis, the most frequent and lethal being endocarditis caused by infectious agents. The most common mechanism is endothelial injury due to blood flow turbulence, be the one generated by a defective valve (rheumatic, bicuspid aortic valve, dysfunctional valve prosthesis), or by any congenital anomaly that causes flow turbulence (interventricular communication, obstructive hypertrophic cardiomyopathy, aortic coarctation).
The most common site of injury, and therefore the most frequent site of vegetation formation, is at the closing line of a valve, usually on the atrial surface of the atrioventricular valves or on the ventricular surface of the ventriculoarterial valves. With the endothelial lesion occurs the formation of a sterile thrombus, which can be colonized by bacteria that multiply there, turning the thrombus into vegetation. These vegetations are avascularized, making the treatment of endocarditis difficult due to the low access of antibiotics to microorganisms.
Answer:
* ARACHNOID MATER
*DURA MATER
*PIA MATER
Explanation:
denticulate ligaments are bilateral extensions of pia mater that thickening the component of collagen of pia mater.It anchors the spinal cord to the dura mater.They are produced by the pia mater of the spinal cord.They provide stability to the spinal cord within the vertebral canal.
Arachnoid mater helps protect the brain and spinal cord from sudden impact. It is connected to the dura mater at the side that is very close to the central nervous system.
Dura mater refers to the membrane that envelops the arachnoid mater. It surrounds the dural sinuses and also provide supports to it. Dura mater carries blood from the brain toward the heart.
The pia mater is part of pseudolymphatic system and it's referred to as the thin fibrous tissue that allows blood vessels to pass through the brain.
I believe the correct answer from the choices listed above is option B. It would be the respiratory and circulatory systems that <span>work together to get cells the nutrients they need to carry out cellular respiration. They are responsible in providing oxygen and other nutrients throughout the body.</span>
Answer:
11 protons
Explanation:
A neutral sodium atom contains 11 protons and 11 electrons. By giving one more electron we get a positively charged Na⁺ ion with a net charge of +1 . But the number of protons remain unchange .
Answer:
A
Explanation:
it takes time for organisms to adapt to their enviroment and requires natural selection to occur in order for the organism to fully adapt, if that makes sense
