TEAS Review (Day 1)Dr. Taha 20231.Best describe adaptive immunityBody's ability to recognize and mount defense against distinct invader2.Adipose tissue is found in which layer of the integumentary system?Subcutaneous3.Which organ shrinks as people age?Thymus glands4.Genetic information describing characteristics is found inNucleus5.Function of circulatory system:To deliver nutrients and oxygenCirculatory system = heart (4 chambers) Left atrium, (mitral valve or bicuspid valve), leftventricle, right atrium, (Tricuspid valve), right ventricleAorta is the largest in diameterBetween left ventricle and aorta is aortic valve or semi lunar valve (eject blood)Aorta going to arteries (arteriole - smallest blood vessels of the aorta)smaller is capillariesAorta -> arteries -> arteriole -> capillaries (smallest blood vessels) -> capillaries -> venole(smallest vein size) -> vein -> superior veina cava (head and arms) and inferior veina cava(legs and rest of body)Deoxygenated blood (dark) = rich with carbon dioxide -> veins, superior veina cava, inferiorveina cava -> right atrium (cumulated blood, deoxygenated blood from entire body) -> rightventricle (close tricuspid valve = prevent backflow of blood from ventricles to atrium)After right ventricle is pulmonary valve to the pulmonary artery, exchange blood at the lungsthrough diffusion, blood is now pinkish, blood pumped from lungs back to heart (left atrium)through pulmonary vein (pinkish, oxygenated blood, rich with oxygen)Mitral valve needs to be closed so blood from the left ventricle does not backflow to the leftatrium.Left side = oxygenated blood; right side - deoxygenated blood6.Which of the following carries deoxygenated blood from the right ventricle to thekings?
