Blood flow through the heart.

Systole is the contraction of the heart while diastole refers to the relaxation part. These terms can refer to only one area of the heart, but they mostly refer to ventricular action. When we take someone’s blood pressure, the numbers that are found are systole / diastole, which is important because it can indicate the status of the heart.

The Aorta and Its Parts The aorta ascends toward the right from the left ventricle. Then it curves posteriorly and to the left. It continues downward posterior to the heart and just anterior to the vertebral column, through the diaphragm, and into the abdomen (Figs. 11-4 and 11-5). The aorta is one continuousartery, but it may be divided into sections:

CRANIAL NERVES ------- Optic nerve (CN 2), sensory only. Receptors in the retina (rods & cones) synapse with bipolar cells, which synapse with ganglion cells. Ganglion cells form optic nerve. Crossover at optic chiasm. Tags: skull, brain, eye, anatomy, dissection, human, body, health, nature, science, biology
