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. Xylem vessels are involved in the movement of water through a plant-from its roots to its leaves via the stem. During this process: Water is absorbed from the soil through root hair cells.ylem and phloem. Plants have two transport systems to move food, water and minerals through their roots, stems and leaves. These systems use continuous tubes called xylem and phloem, and together they are known as vascular bundles. Plant root. Plant root.
