Torso

Torso means trunk.
The torso or trunk is an anatomical term for the central part of the many animal bodies (including that of the human) from which extend the neck and limbs. The torso includes the thorax and the abdomen.

The thorax or chest (from the Greek θώραξ thorax "breastplate, cuirass, corslet" via Latin: thorax) is a part of the anatomy of humans and various other animals located between the neck and the abdomen The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain.

Anatomy of neck

The neck is the part of the body that separates the head from the torso. The Latin-derived term cervical means "of the neck." The neck supports the weight of the head and is highly flexible, allowing the head to turn and flex in different directions. ... The cervical spine is made of 7 cervical vertebrae deemed C1 to C7

The neck is the part of the body, on many vertebrates, that separates the head from the torso or trunk. It contains blood vessels and nerves that supply structures in the head to the body. These in humans include part of the esophagus, the larynx, trachea, and thyroid gland, major blood vessels including the carotid arteries and jugular veins, and the first part of the spinal cord.

In anatomy, the neck is also called by its Latin names, cervix or collum, although when used alone, in context, the word cervix more often refers to the uterine cervix, the neck of the uterus. Thus the adjective cervical may refer either to the neck (as in cervical vertebrae or cervical lymph nodes) or to the uterine cervix (as in cervical cap or cervical cancer).

Diseases of Human Brain

Brain Diseases: Infections. Brain diseases in the category of infections include: Meningitis: Aninflammation of the lining around the brain or spinalcord, usually due to infection; Neck stiffness, headache, fever, and confusion are commonsymptoms.

Brain, being the sensitive and master organ in the body, is equally susceptible to any kind of infections and other disorders of varying intensity, such as brain cancer, tumors, Alzheimer's disease, alcoholism, amnesia, altitude sickness, autism, epilepsy, and so on. Each of these conditions adversely affects the functions of brain. Though it is very difficult to address the complex mental abnormalities, considerable advancement in the field of health science and medical research has offered various remedial strategies to most of such conditions. Now let's discuss, turn by turn, some of the major brain diseases list with their diagnostic symptoms and frequently recommended treatment measures. Some disorders affect the organ as a whole while other do harm to only certain parts of brain.

Human Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body. In a human, the 
The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating .

What Is the Function of the Lungs?

The lungs are a pair of organs located in the chest cavity that perform respiration. These are about 12 inches long. The lungs are a protective membrane. The area between the two lungs is called the mediastinum, which contains the heart, trachea, esophagus and blood vessels. The lung is protected by the ribcage.

Purpose of the Lungs

The purpose of the lung is for oxygen to enter the body, while removing carbon dioxide. Oxygen provides the body with energy, while carbon dioxide is a bodily waste produced by cellular metabolism that collects in the tissues of the body.

Statistics

According to the American Lung Association, our lungs breathe in 8,000 to 9,000 liters of air of air daily in order to meet the demand of 8,0000 to 10,000 liters of blood that is pumped in through the heart.

Breathing

The lungs oxygenate the body because air is breathed in via the nose or mouth. When a person breathes in, the lungs expand and need assistance from other muscles in order to function properly. When a person breathes out, or exhales, the lungs do not need assistance.

Respiration

The function of the lungs is to maintain the body's respiration, which means that the lungs bring oxygen to the bloodstream via alveoli, or tiny sacs in the lungs. When oxygen enters the blood, hemoglobin picks it up and transport it throughout the body. The lungs also remove carbon dioxide from the bloodstream, disposing of the waste by product of the body. When the lungs do not work properly, it means that oxygen is not getting to the body and that they need to work harder to function. Problems with the lungs, such as pneumonia, lung disease, asthma or other problems put more stress on bodily functions.

Protection

The nose acts as a filtering system, decreasing the number of irritants that enter the lung. The nose also adds heat and moisture to the air. Breathing in through the mouth does not filter oxygen, so more irritants may be delivered to the lungs. The lungs also protect themselves by coughing, as it can expel irritants easily. When the lungs are irritated, the muscle surrounded the lung begins to tighten to keep an irritant out. This tightening causes a spasm, which can make it more difficult to breathe. These can be signals to the body that there is an infection or irritant that should be avoided or treated.
