Can someone please answer this?

Thank you

ill start from the right atrium

from the right atrium blood travels through the tricuspid valve and into the right ventricle

from the right ventricle blood travels through the pulmonary valve and into the pulmonary arteries where it enters into the lungs

from the lungs blood flows back into the heart through the pulmonary veins and into the left atrium

from the left atrium blood travels through the mitral (aka bicuspid) valve and into the left ventricle

from the left ventricle blood enters the aortic valve and goes through the aorta where the blood enters the body

then it returns to the heart via the vena cavae

and the process starts over!

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

it should be briana that has it to me
