importance of physical fitness in human health

Exercise makes our body healthy and active. When
a persons does not do exercise his/her body became
weak he/she becomes lazy, gains weight and suffer
from many kinds of of diseases like indigation, heart disease and also suffer from mental problems.Physical fitness is pre-requirement to perform any task. A person who is physically fit can do any work adequately. Physical fitness keep s a persons healthy, strong, energetic and active. Our body function under muscular and organic power. This power can be developed to a top limit through regular exercise. A person can be called physically fit only when he/she has developed muscular and organic power adequately with the highest possible efficiency. The highest possible efficiency defers from person to person. The limit is generally determinant by the heredity and health of a persons. it means a persons potential physical capacity may not be the same to others due to his health and heredity.

The purpose of mouth-to-mouth resuscitation is to help patient revive natural breathing and rescue him/her from breath obstruction.
The procedure of mouth-to-mouth resuscitation.
i. Set of procedure to carry out mouth-to-mouth resuscitation.
ii. first the patient is placed on his/her back on surface
iii. Food etc is quickly cleaned out from the mouth to prevent obstruction any air passage
iv.The patient head is extended as far as possible to keep the airway open
v. The patient's nose is pinched with the operator's finger to prevent any linkage
vi. The operator's mouths scaled around the patient's mouth to stop any air linkage
vii. Air is then blown into the lung until the patient's chest is seen to expand
viii.The operator's mouth is quickly removed to allow passive breathing

AIDS Virus The Human Immune Deficiency Virus (HIV), which causes acquired immune deficiency syndrome (AIDS), principally attacks T-4 lymphocyte, a vital part of the human immunology system. As a result, the body's ability to resist opportunistic viral, bacterial, fungal, protozoa l, and other infection is greatly weekend. Pneumatically Carina pneumonia is the leading causes of death among people with HIV infection but the incidence of certain times of cancers such as B-cell lymphomas and Kaposi's sarcoma is also increased. Neurological complications and dramatic weight loss,or wasting,are characteristic of AIDS, which is end stage HIV disease. HIV is transmitted sexually; through contact with contaminated blood, tissue or needles; and from mother to child during birth or breast feeding. full blown symptoms of AIDS may not develop for more than 10 years after infection.
T-lymphocyte infected with HIV is the causes of AIDS . By infecting CD4 T- lymphocytes , a type of white blood cell, HIV weakens the immune system and leaves the infected individual open to deadly infections. The viruses gain access to a T-lymphocyte by attaching to CD4 pr0teins on outer surface of the cell membrane.

the skeletal is the framework of the body and usually described in two parts. The axial skeleton comprise the skull, vertebral column, rib cage and strum. The skull forms a protective cells for the brain and sensory organs, with the lower part of the skull giving form to the face.
The appendicular skeleton includes the limb bones of the arm and legs, and the girdles that connect then to the axial skeleton, the shoulder girdle and the pelvic girdle. The bone of the arm (humerus, radios and ulna) and the leg(Femur,tibia and fibula)are all long bones.

Joints
Whenever we move, turn bend or twist, our joints are involved. The point where two bones connect is called joint. Exclusive to the skull are the joints known as sutures, which knit the bones of the skull together to form a stable, immobile joint. Throughout the rest of the body are various mobile joint types; ball and socket, hing gliding ,pivot and saddle joints. varying degrees of mobility are achieved by the various joint offering the greatest range of movement. Some joints, such as those joining at the front of the pelvis,are only slightly movable joint, connected by a layer of cartilage and held firm by fibrous ligaments. The surface of synovial joints are covered with smooth cartilage.

THE CIRCULATORY SYSTEM OF HUMAN BEIOG
The blood vessels and heart from the circulatory system, pumping blood through their complete circuit and caring oxygen to the organs and tissues of the body. The heart pumps oxygen to reach blood through the body, distributing it through arteries and capillaries and supplying oxygen and nutrients vital to the functioning of the internal organs and tissues. After exchanging gases with surrounding tissues, the blood now oxygen depleted and laden carbon dioxide returns to the heart through the veins. This is known as systemic circulation. The another one is pulmonary circulation, transfer blood returning to the heart, along the pulmonary trunk and arteries to the lungs for oxygen and elimination of carbon dioxide. This renewed blood is returning to the systemic circulation, ready for another circuit of the body.

Heart
The heart is divided into four chambers. The left and right atria and the left and right ventricle. It pumps blood out from the left and right ventricles,and collects returned blood into it's left and right atria.

Blood
Blood is a suspension of red and white blood cells, platelets, protein and chemical in a fluid called plasma. Blood caries oxygen and essential nutrients from the lungs and digestive track to another parts of the body and caries waste products to organs such as the kidneys and lungs for elimination.The red blood cells carry oxygen to the body tissues, exchanging oxygen for carbon dioxide, which they takes to the lungs. The white blood cells play a role in the immune system and platelets are involved in the clotting process.
