where are the kidneys located :

Kidney

Kidney is a bean shaped glandular organ. Each kidney is approximately 11 cm long 5 cm wide 2.5 cm thick, each of them weighs about 150 gms.

Kidney work as filter and purifies the blood, if sometimes the level of sugar salt or water in blood exceeds kidneys excrete the excess amount. They also regulate the formation of urine according to the exigencies of the situation thus do not allow the blood to become extra thick or thin. The undesirable acids and bases of the blood begin of the body as urine.

body of lies/body mechanics

Each kidney has millions of coile & capillaries, blood enters the kedneys through the renal artery and passes through these capillaries and dissolved impurities are filtered out. The impurities removed form the blood pass from thee kidneys to bladder. Normally an ordinary person passes 1.5 liters of urine in one day.

 Lungs function :

Lung

Lungs function are a pair of rubbery organs which are positioned in the chest, well protected by the rib cage. Their function is to taken in oxygen needed for respiration and to pass out waste carbon dioxide and water vapours from the body. The oxygen come from the air breathed in through the trachea. The trachea divides in to bronchi and these divide in to bronchioles, which ends into tiny air saces called alveoli, which is more than 300 millions big blood vessel from the guts referred to as arteria pulmonalis divides in to 2 branches, each getting to one among the lungs function. here they divide again and again until they become tiny blood vessels called capillaries. The oxygen breathed into the alveoli passes through the skinny alveoli walls and enters the capillaries from the guts . Once this exchange of oxygen for carbon dioxide has taken place, thee bright red oxygen laden blood goes in to the pulmonary veins and back to the heart to be pumped around the body.

Blood diseases :

Many kinds of bacteria and viruses affect the heart, blood diseases vessels and blood and creates health problem. The Leukemia is a disease which effect one or more of the types of white blood cells. They become cancerous and unable to carry out their roles and multiply out of control. The illness anemia is caused by a deformation of red blood cells which decline body’s ability t carry oxygen around the body. This creates fatigue, paleness and fainting. Heart valves can become lose or frayed so that they do not close fully allowing blood flow the wrong way. They may also become stiff and unable to open fully. This causes the infection in the valve. Blockage in the coronary artery may bring the heart disease. HIV (human immunodeficiency virus) attacks certain types of white blood diseases cells. Hypertension responsible for causing heart disease.

The red story blood :

Blood transports oxygen from the lungs to body tissue and CO2 from body tissue to the lungs. blood is thee fluid of growth, transporting nourishment from digestion and hormones from glands throughout the body. Blood is that the fluid of health, transporting disease fighting substances to the tissue and waste to the kidneys. Because it contains living cells, blood is alive. Red blood cells and white blood cells are liable for nourishing and cleansing the body. Vitamins and Minerals keep the blood healthy. The blood cells have a particular life cycle. Approximately 55 percent of blood is plasma. The liquid plasma carries the solid cells and thee plate lets which help blood clot.

Heart structure :

The heart structure is a hollow muscle in the middle of the chest pumps blood around the body, supplying cells with oxygen and nutrients. A muscular wall, called the septum, divides the heart structure lengthwise into left and right side. A valve divides each side into two chambers. An upper atrium and a lower ventricle. When the guts muscle contracts, it squeeze blood through the atria then through the ventricles.

Oxygenated blood form the lungs flows from the pulmonary veins into the left ventricle, and then out via the aorta to all parts of the body. Deoxygenated blood retuning form the body from the vena cave into the right ventricle, and then out via the pulmonary artry to the lungs for reoxygenation. At rest the guts beats between 60 and 80 times at minute during exercise or sometimes of stress or excitement the speed may increase to 200 beats at minute.

Nervous system function :

The central nervous system function is the body’s internal electrochemical, communications network. It’s main parts are the brain, spinal cord and the enerves. The brain and the spinal cord forms thee central nervous system (CNS), the body’s chief coordinating centers. Billions of long neurons many grouped as nerves makes up the peripheral nervous system, transmitting nerve impulses between the CNS and other region of the body. Each neuron has three parts: a cell body, branching dendrities that receives chemical signals from the other neurons system function, and a tube like axon that conveys these signals as electrical impulse.

Your brain :

Jelly like mass of fat and protein weighing about 1.4 kilograms is our primary control center that is our brain. The cerebrum biggest a neighborhood of the brain makes up 85% of the brain’s weight. It is at the back of the brain. Cerebellum is only 1/8 of cerebrum. It controls balance and movement. The brain stem connects the remainder of the brain to the medulla spinalis , which runs down from neck and back. The pea size pituitary gland produces and release hormones into body. The hypothalamus controls shivering and sweating and maintains the body temperature. It’s the medulla spinalis and nerves referred to as the systema nervosum that permit messages flow back and forth between the brain and body.

Gurugyan :

Your left lung is smaller than your right lung to form room for your heart. This process is called aphaeresis.

Yellow colour of the urine is due to urea. If you eat a diet rich in protein you will be having dark yellow urine.

One tea spoon of blood contain 250 billions read blood cells an 17.5 billion platelet and 200-550 millions white blood cells.

By the end of a long life, a person’s heart may have beat more than 3.5 billon times. Heart pumps on an average approximately 300 liter of blood in one hour.

Never impulses to and from the brain travel as fast as 170 miles per hour.

The weight of a mean human brain is about 1300-1400g.
