Answer:
Health problems. Illness and disability, chronic or severe pain, cognitive decline, damage to your body image due to surgery or sickness can all be contributors to depression.
Explanation:
As we grow older, we often face significant life changes that can increase the risk for depression.
Really, none of these answers are good. leukocytes are the body's general immune cell, and lymphocytes are a type of leukocyte. Antibodies are only used when fighting an infection that your body already has experience with, so I'm guessing it you have to pick from these answers, its "lymphocytes", but it's not really the best answer.
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.
I believe the correct answer is involuntary
<h2>Explanation</h2>
The human body has 2 groups of muscles; voluntary and involuntary that are divided into 3 types of muscles: Cardiac muscles found only in the heart, smooth muscles found in hollow organs and also internal organs and skeletal muscles that support the human skeleton and also protect organs. An example is the thigh muscle. Of the muscles, Cardiac muscles and smooth muscles are completely involuntary in addition to diaphragm which is a skeletal muscle.
<h2>Further Explanation</h2><h3>1. Cardiac Muscle</h3>
The cardiac muscle is found only in the heart and is controlled by the brain only. It is the reason why your heart beats without your control. The part of the brain responsible for this control is a region called pons in the hind brain. It is an involuntary muscle. It also is different in structure to all the other types of muscles.
<h3>2. Smooth muscles</h3>
These are muscles found in organs and also lining of some organs such as blood vessels and the bronchioles. They also form organs such as the liver, lungs and uterus. They are involuntary muscles that are under the control of the brain and perform functions such as breathing and regulation of body temperature and blood pressure.
<h3>3. Skeletal muscles</h3>
This is the most common type of muscle and is found in almost everywhere you touch for example the thighs, arms, legs, head, chest. They are tough muscles that coordinate to help the skeleton in movement, protect internal organs and also link up body parts. You can control them and they are voluntary. For example, when you stand up you use your skeletal muscles.
