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 cardiovascular system of the upper torso includes the heart and most of the major blood vessels of the circulatory system. These vital structures are critical to the process of pumping deoxygenated blood to the lungs for gas exchange as well as pumping oxygenated blood to the bodyâs tissues to support their metabolic functions.
