Anatomy of human body 2

ok i'll countinue my post about anatomy of human body..now i'll explain about circulation.

i'll begin with general circulation of human body..

our circulatory system consists of your heart and blood vessels. Together, these provide a continuous flow of blood to your body, supplying the tissues with oxygen and nutrients. Arteries carry blood away from the heart; veins return blood to the heart. 

this the diagram:

this ficture draw about our circulation general ,

next i get about arteries and veins..

 arteries carry blood away from the heart. Oxygenated blood is pumped out of the heart through the body's main artery — the aorta. Arteries that branch off the aorta transport blood throughout the body, supplying tissues with oxygen and nutrients. 

veins carry blood back toward the heart. Tiny vessels called capillaries in organs and tissues of the body deliver deoxygenated blood into small veins called venules, which join to form veins. Blood flows through the veins to the body's two main veins (called the vena cavae), which deliver the blood back into the heart.

Anatomy of human body Part !

in this post i'll give you basic  anatomy of human body step by step..
1. Torso

    Your torso consists of two parts — the chest and the abdomen. The chest contains your heart and lungs; your abdomen contains the digestive and urinary systems. Your chest and abdomen are separated by a dome-shaped sheet of muscle called the diaphragm.
2.Brain.

cerebrum

Your brain has three main components - the cerebrum (which consists of the left and right cerebral hemispheres), the cerebellum, and the brain stem. The cerebral hemispheres of the brain make up the largest part of your brain. The cerebellum is the structure located behind the brain stem,  and the brain stem is the lowest section of the brain and is connected to the spinal cord. 

cerebellum

The cerebrum (the portion of your brain that performs motor and sensory functions and a variety of mental activities) is divided into four lobes - the frontal, temporal, parietal and occipital lobes. Some of these lobes are separated by deep grooves called fissures.

brain from side

The central structures of the brain are the thalamus, hypothalamus, and pituitary gland. The thalamus relays sensory information to the cerebrum; the hypothalamus helps regulate body functions such as thirst and appetite, as well as sleep, aggression, and sexual behavior; and the pituitary gland produces hormones that play a role in growth, development, and various other physiological variables. The pons, medulla, and midbrain are the three structures that compose the brain stem. The ventricles are natural cavities inside the brain filled with cerebrospinal fluid.

Development of health sciences of the 18th century

Thank you for the advancement of agriculture in the U.S. such ascorn and potatoes, it can anticipate the needs of food and support the reduction in populations exposed to disease and

This post is a continuation of previous post ..

 Development of health sciences in the late Middle Ages
In Europe the population is growing rapidly as a result of urbanization, trade and the many people who perform the pilgrimage, so many of leprosy arose that culminated between 1200 and 1300 century.

Health and illness concept

before we talk more about health and the various reviews in it, we should first understand the concept or the meaning of health.because without a knowledge base will be more difficult for us to understand than we previously understood about the basis of something we want to learnokay let's start all the concepts of healthy and sick

HEALTH AND ILLNESS

Health (health) is a concept not easily understood even if we can feel and observe the situation. For example, one can not have physical complaints seen as a healthy person.As a reference for understanding the concept of "healthy", Organitation World Health Organization (WHO) formulated in a very broad mean namely, "a state of perfect physical, mental and social, not only free of disease or infirmity / disability". 
 Healthy is not just free from disease or disability.  
People who can not be said diseased not necessarily healthy. Supposedly he was in a state of perfect physical, mental or social.This understanding is an ideal situation in terms of biological, psychological and social. The concept of "pain" associated with the three concepts, in the English language that is disease illness and sickness. The third term implies a dimension bispikososial. Disease-dimensional biological, psychological dimension illness, sickness sociological dimension (Calhoun, et al, 1994).
 Diaease disease means a deviation that simptomnya known by diagnosis.  
Disease and the biological dimension of objective, independent of psychosocial considerations, there is no influence conviction against a person or society.Illness is a psychological concept that refers to persaan, perception, or a person's subjective experience of morbidity or state body that feels uncomfortable. As a subjective experience, then this illness is individual.While sicknesss is significant sociological concepts as social acceptance of a person as a person who is experiencing pain (illness or disease). In the circumstances warranted the release of this sickness responsibility, role, or certain habits which made sense because of morbidity time.
  Because the definition of "sick" it may subjective dimension-kulturalistik, every society has its own understanding of the illness according to the experience and culture. Sick role can only be made and recognized by society as appropriate to the consideration of values, beliefs social norms. Therefore, a pain that felt and acknowledged by the individual or society is not always the same dirasaskan by other individuals or communities (Lyttle, 1986; Pacther, 1994).
purpose of the concept of healthy pain is so that people can:
1. Understanding health and illness
2. Understanding the cause of an illness
3. Authorizes the person to a healthy or diseased condition specifies
4. Responding to the agony AAU simptomnya
5. Establish the classification of pain
conclusions:
Based on the notion of healthy and ill health are briefly state that:
A. Is a sense (construct) that samgat loosely understood differently by the public
2. Based on the qualitative as it can be understood according to the feelings and perceptions
3. Continuum state of nature because of its position are at two opposite extremes, which is a healthy point on the one hand and a sore point on the other side.
