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.
People become skeptical due to the overflowing abundance of scientific evidence that backs more proof with certain treatments. It makes people more comfortable over all if it is more tested. It would help prove theories if people were more skeptical, since they didn't think it would work previously.
Behavior
The phylogenetically ancient limbic lobe, together with other subcortical structures and their interactions, make up the limbic system. The limbic system is a functional notion that may be used to explain a variety of brain activities, while not having any scientific support.
The limbic system is the area of the brain that controls our behavior and emotions, particularly when it comes to actions we must do to ensure our survival, such as eating, reproducing, and caring for our young, as well as fight-or-flight reactions.
The limbic system's components are hidden deep inside the brain, above the brainstem and below the cerebral cortex.

The talk test is a one of the easiest ways to monitor your exercise
intensity. You don't need any equipment, like a heart rate monitor.
All you really need is the ability to talk and breathe.
Whether you can do both at the same time is where your intensity comes in.
The posterior pituitary (or neurohypophysis) comprises the posterior lobe of the pituitary gland and is part of the endocrine system<span>. Hormones known as posterior pituitary hormones are synthesized by the </span>hypothalamus<span>, and include </span>oxytocin<span> and</span>antidiuretic hormone<span>.
