How many cusps are located on the right atrioventricular valve

3

Explanation:

these are are located between the right upper atrium and lower right ventricle. These cusps are

1.Anterior

2. Septal

3. Posterior.

Anatomically, the base of each cusp is held firmly or anchored by fibrous structure called CHORDAE TENDINEAE.

Thier functions is to pevent regurgitation of the blood and the wall of the right ventricle into the atrium during ventricular systole; contraction of the ventricle.Therefore they blocked the passage and ensured blood flows into the pulmonary arteries to reach the lungs.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
