Pulmonary arterial hypertension (PAH) is a progressive disease caused by narrowing or tightening (constriction) of the pulmonary arteries, which connect the right side of the heart to the lungs.

An example of a carrier protein that carries out passive transport is the glucose transporter, which is located in the plasma membrane of all mammalian cell types. On liver cells the carrier can be open toward the outside of a cell or toward the inside (Fig. 14).n example of a carrier protein that carries out passive transport is the glucose transporter, which is located in the plasma membrane of all mammalian cell types.
