A theme in biology is how structure is related to function. Discuss how the structures of the different chambers and vessels of the heart relate to their functions. Answer should consist of 3-5 sentences, citing specific chambers of the heart to their function and why.

Different chambers of the heart perform different functions.

Explanation:

The human heart has four chambers the two atria as well as two ventricles. The function of the lower chambers of the heart is to pump out blood. The atria or upper chambers receive blood. The right atrium obtains blood from the superior vena cava then the blood moves towards the right ventricle where the deoxygenated blood is pumped out to the lungs. From the left ventricles the blood is pumped to all the parts of the body.

i think its through the fallopian tube

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
