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.
Xylem vessels xylem vessel: Vein-like tissue which transports water and minerals up a plant are involved in the movement of water through a plant from its roots to its leaves. Water: 1  Is absorbed from the soil through root hair cells.hloem. Phloem vessels phloem vessel: Vein-like structures through which food is transported round a plant are involved in translocation translocation: The transport of dissolved material within a plant. . This is the movement of food substances from the stems to growing tissues and storage tissues.
