Ooh this will be good
So blood let’s say starts in the left atrium where it goes down through the mitral valve into the left ventricle. From the left ventricle of the blood is pushed through the aorta and from there through the various branches of the body eventually allowing oxygen rich blood to flow all across the body. Once this blood is picked up by veins as deoxygenated blood it goes back to the heart through the inferior and superior vena cava. From there the deoxygenated blood is sent into the right atrium, through the tricuspid vale into the right ventricle, through the pulmonic valve into the pulmonary artery and into the lungs for re-oxygenation. The re-oxygenated blood (oxygen rich blood) now goes through the pulmonary veins into the left atrium and the cycle beings again.
Remember this, Left side of heart is for oxygenated blood, Right side of heart is for deoxygenated blood.
Artery takes oxygen rich blood away from heart itself
Vein takes oxygen poor blood back into the heart
Exceptions, Pulmonary Artery takes oxygen poor blood away from heart and into lungs
Pulmonary vein takes oxygen rich blood into the left atrium to be pushed to the rest of e body.
While the sun does emit ultraviolet radiation, the majority of solar energy comes in the form of "light" and "heat," in the visible and infrared regions of the electromagnetic spectrum.
Answer: State the hypotheses. Every hypothesis test requires the analyst to state a null hypothesis and an alternative hypothesis.
Formulate an analysis plan. The analysis plan describes how to use sample data to accept or reject the null hypothesis.
Analyze sample data.
Interpret the results.
Explanation:
Because our brains are the most developed out of all of the other species on this planet. Also, we require the most maintenance to survive. We can’t live in the ocean, such as a fish, shark, dolphin, etc. but we also can’t live in the forest such as bears, deer, coyotes, etc. we need to live in a stable environment when we will have enough food to survive as well to live in certain temperatures that are best suited for our kind. Hopefully that helped a little bit
