Salsa de Molcajete. Salsa de Molcajete refers to a salsa that is ground by hand in a molcajete, Mexico's version of the mortar and pestle. Nearly all salsas used to be prepared this way, but now many cooks use blenders and food processors. Because of this, even in Mexico the term evokes nostalgia for the handmade quality of bygone days.
Overview. The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus.
The respiratory system provides oxygen to the bodyâs cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the bodyâs exterior.The lungs...ulmonary ventilation is the process of moving air into and out of the lungs to facilitate gas exchange. The respiratory system uses both a negative pressure system and the contraction of muscles to achieve pulmonary ventilation.
