Human Respiration System:-

Human respiration relies on an involuntary muscle reflex that reflex that makes the diaphragm and external intercostals muscle contract. This increases the volume of the chest cavity, and the pressure inside it drops. Air rushes in through the nose, down the trachea, and into the lungs, where an exchange of oxygen and carbon dioxide takes place. As the muscle relax, the air is forced back out of lungs.

Skeleton System

The human skeleton supports the body, protects the internal organs and provides anchorage for the muscles. It consists of bones and connective tissue called cartilage. Although an individual bone is around five times  stronger than a steel bar of similar weight,  the many joints in a skeleton allow a wide range of movement. The human skeleton contains 206 bones and consists of two main group: the axial skeleton and the appendicular skeleton. To allow for childbirth, the female pelvic cavity is shallower and wider than the man cavity.

Nervous system

The nervous system is a network of fibers and neurons controlling the actions and reaction of the body. The central nervous system comprise the brain and spinal cord, which receive and integrate singles relayed from the sense organs via the peripheral nervous system. The latter includes the autonomic nervous system, which controls unconscious functions, such as heartbeat and breathing.

Kidney:-

(1)About:-   

In the human body, the two kidneys, each up to 12 cm long,are located ate the rear contain some one million filtering units, which process the blood, regulating both volume of water within the body and levels of salts within body fluids.Most water and virtually all nutrients are reabsorbed in to the blood,While excess water and waste product products are expelled from the body as urine.

(2)Symptoms:-

1.Changes in urination

2.Swelling

3.Fatigue

4.Skin Rash

5.Shortness of breath

6.Feeling cold

 Here you have to know some disease of kidney,

 (1)Stone:-

Symptoms:-

1.Nausea and vomiting2.Blood in the urine3.Severe pain in the back, belly, or groin4.Frequent or painful urination

Treatment at home:-

If a kidney stone seems small enough, your doctor may recommend you take pain medicine and wait for the stone to pass out of the body on its own. During this time, your doctor may recommend that you drink enough water and fluids to keep urine clear -- about eight to 10 glasses a day.

(2)Nephritis:-

Think of your kidneys as your body’s filters, a sophisticated waste removal system comprised of two bean-shaped organs. Every day, your hard working kidneys process 200 quarts of blood in a day and remove two quarts of waste products and excess water. If the kidneys suddenly become inflamed, you will develop a condition called acute nephritis. Acute nephritis has several causes and can lead to kidney failure.

Causes:-

   Having low potassium in your body supply. Potassium is mineral that help regulate many function in body.including metabolism.

 Taking medication  for long period of time the damage the tissue of the kidney.

Treatment:-

 you may need to drink more water than you usually do. Water helps you kidney flush out any waste products that maybe hampering your recovery.

  

Some facts:-

Phagogyte:-

A phagocyte is a cell that can surround engulf, and digest micro-organisms,foreign particles that have entered the body and cellular debris. Phagogyte from part of the body's  immune system and  are found in the blood,spleen,lymph nodes,alveoli and elsewhere. Some types of white blood cell are 'free' phagocytes,able to wander through tissue and absorb micro-organisms.

Pharynx:-

    the pharynx is a muscular passage lined with mucous membrane that extends from the nasal cavity to the oesophagus. The upper part, the nasopharynx, connects to the ear via the eustachian tube and acts as an air passage. The oropharynx, a passage for air and food,lies between the soft pLte and the upper edge of the epiglottis.The laryngopharynx lies below the epiglottis and opens in to both the larynx for breathing and the oesophagus for swallowing, 

Body,Bone and Cell:-

1.Body:-

         The human body consists of a number of interacting 'systems'.The skeleton forms a rigid framework,Which,attached system responsible for the body's reaction to stimuli. Hormones, produced by the endocrine system,control many functions,including growth and developmental changes such as puberty. The cardiovascular system circulates blood around the body,delivering oxygen and nutrients and collecting carbon dioxide and waste,while the respiratory system fights infection.The digestive system derives energy and nutrients for growth and repair from food,and with the urinary system eliminates waster;the urinary system also helps to regulate chemicals in the body. The reproductive system is concerned with producing offspring. 

2.Cell:-

        The cell is the basic structural unit of every living things,and most plants and animals are composed of millions of them.cells work in unison to perform the tasks necessary to keep an organism alive.They vary is shape according to function;a human red blood cell is disk-shaped,while a nerve cell is thread like and ma
y be a matre long.Unlike animal cells,plants cells can produce their own food through photosynthesis.  

3.Bone:-

       Each layer of a bone is composed of specialized cells,protein fibres, and minerals. The medullary cavity contains bone marrow, and is enclosed in a spongy cancellous layer.This is surrounded by hard cortical bone,with an outer covering of periostium. This cobinataion of layers make bones strong and light.

Relationship Facts:-

1.About:-

         In relationship main role is love.love is just one time of attraction  between two human.it is a just hormonal change in our body when see some good looking face.

 hear I am show about what is love,relationship?etc....

              the adrenaline is increasing you blood level and cortisol. when you see some fancy face.and emergence feeling for him or her.

               Adrenaline is powerful hormone in our body.is produce by adrenal glands.

2.Dopamine:-

             is one neurotransmitter. dopamine is control the brain's rewards. dopamine is regulate emotional responses.

3.Oxytocin:-

             oxytocin is powerful hormone.kiss,hug or love one in our body oxytocin level increasing. when increasing oxytocin in our body have some changes.such as feelings,love. etc...
