Pretend you are a red blood cell. You just gave oxygen to the left biceps femoris muscle, and your next mission is to take oxygen to the right temporal lobe of the brain. Take me on the path. State every vessel, chamber, valve, and structure you will go through to accomplish this.

Is given on the explanations

Explanation:

After supplying oxygenated blood to the bicep femoris muscle via the branches of the femoral artery, deoxygenated blood is carried to the heart through the inferior vena cava. In the heart, the deoxygenated blood flow to the right right atrium, as the atrium contracts, blood flows from the right atrium into your right ventricle through the open tricuspid valve.

When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts. As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated again, after receiving oxygen, blood flows back to the heart through the pulmonary vein. The pulmonary vein empties this oxygenated blood from the lungs into the left atrium.

As the atrium contracts, blood flows from the left atrium into the left ventricle through the open mitral valve.

When the ventricle is full, the mitral valve shuts. As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta from the aorta the blood flows via two primary sources to supply the temporal lobe, the internal carotid system and the vertebrobasilar artery (which originate from the subclavian artery). The internal carotid system contains the anterior choroidal artery and the middle cerebral artery. The blood flow from the anterior choroidal artery supplies the uncus, amygdala, and the anterior parahippocampal gyrus. The middle cerebral artery branches into the temporopolar artery, anterior temporal artery, middle temporal artery, and posterior temporal artery. It supplies the temporal pole as well as the superior and inferior portions of the temporal gyri. Blood flow from the vertebrobasilar system supplies the inferior surface of the temporal lobe from the temper-occipital artery.
