Describe the structure of a neuron. Include the cell body, dendrites, and axon in your description. How does the structure of a neuron help it carry out its function efficiently?

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

thats not even an aswer choice
