WebAscent from sea level to high altitude has well-known effects upon respiration. The progressive fall in barometric pressure is accompanied by a fall in the partial pressure of oxygen, both in the ambient air and in the alveolar spaces of the lung, and it is this fall that poses the major respiratory challenge to humans at high altitude. Humans and some … WebExplain how the villi and the alveoli are adapted to absorb molecules into the bloodstream. (6) Villi are folds within the wall of the small intestine across which digested food molecules are exchanged between the gut and the bloodstream.
