Airway Clearance. Respiratory health depends on consistent clearance of airway secretions. Normal airway clearance is accomplished by two important mechanisms: the mucociliary clearance (MCC) system and the ability to cough. Impaired MCC is linked to poor lung function in a broad range of diseases and disabilities.
The xylem and phloem carry water and nutrients throughout a plant while the veins and arteries carry blood in a body. The xylem and phloem transport things up and down and veins and arteries carry blood to and from the heart.
Entry of water into plants-Vascular tissues. root. stem. phloem. xylem. Xylem-Transport water, and soluble mineral nutrients from the roots throughout. Transport in Plants - 2. transport mechanisms. water first enters the roots and then. TRANSPORT IN PLANTS - 2 types of transport tissue: xylem & phloem.
