Answer:
Explanation:
The Respiratory System
The thoracic cage, sometimes called the rib cage, is a bony structure that is narrower at the top and wider at the base. It is held in place by the thoracic vertebrae of the spine in the center of the back and by the sternum in the center of the anterior aspect of the body. The first seven ribs attach directly to the sternum and are called the true ribs. Ribs 8, 9, and 10 fasten one to another, forming the false ribs, and ribs 11 and 12 are the “floating” ribs, or half ribs, because their only attachment is to the thoracic vertebrae. At the base or floor of the rib cage is the diaphragm, a musculotendinous membrane that separates the thoracic cavity and the abdominal cavity (Figure 46-1). The respiratory system is divided into two anatomic regions, the upper respiratory tract and the lower respiratory tract.
Upper Respiratory Tract
The upper respiratory tract, which transports air from the atmosphere to the lungs, includes the nose, pharynx (throat), and larynx (Figure 46-2). As air enters the nasal cavity, it is cleaned by the cilia, warmed by capillary blood vessels, and moistened by mucous membranes. The paranasal sinuses, hollow cavities that also are lined with mucous cells and cilia, open into the nasal cavity and help warm and moisten inhaled air. The filtered, warmed, and moistened air moves past the tonsils, which have an immunity function and help defend the body from potential pathogens, and through the pharynx. As the air continues toward the lungs, it passes through the larynx. The opening into the larynx is protected by a moveable piece of cartilage, the epiglottis. The larynx, or voice box, is made up of vocal cords, which vibrate when air is exhaled, creating the sound of the voice. Once the air passes through the larynx, it enters the lower respiratory tract.

Answer:
decrease depolarization of the cell
Explanation:
Dysrhythmias is also known as cardiac dysrhythmias, which can be described as an irregular heartbeat, that is an abnormal rhythm of the heartbeat, which may be due to the changes in the heart's normal sequence of electrical impulses.
The following has been described as the things that can cause dysrhythmias,
*Coronary artery disease.
*Electrolyte imbalances in your blood (such as sodium or potassium).
*Changes in your heart muscle.
*Injury from a heart attack.
*Healing process after heart surgery.
*Irregular heart rhythms can also occur in "normal, healthy" hearts
Some of its symptoms are
Pounding in your chest.
Dizziness or feeling light-headed.
Fainting.
Shortness of breath.
Chest discomfort
It should be understood that, Beta-blockers such as metoprolol or Toprol XL and Calcium channel blockers such as verapamil or Calan can be used as medications for treatment.
In this case, the local anesthetics will work by decreasing depolarization of the cell.
Jake could include a variety of food groups in his meal- e.g: Protein, Fibre, Vitamins and minerals. An example of a balanced meal would be :
Salmon and egg salad with cucumber, lettuce, tomatoes, carrot and olives.
