    The heart is an amazing organ. It pumps oxygen and nutrient-rich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day. Your heart is a key part of your cardiovascular system, which also includes all your blood vessels that carry blood from the heart to the body and then back to the heart.

    The heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon dioxide for oxygen. The heart is a hollow, muscular organ, which functions as a pump for the movement of blood through the body.

    Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration: Urea 9.3 g/L. Chloride 1.87 g/L. Sodium 1.17 g/L. Potassium 0.750 g/L. Creatinine 0.670 g/L . Other dissolved ions, inorganic and organic compounds (proteins, hormones, metabolites). Urine is sterile until it reaches the urethra, where epithelial cells lining the urethra are colonized by facultatively anaerobic gram-negative rods and cocci. Urea is essentially a processed form of ammonia that is non-toxic to mammals, unlike ammonia, which can be highly toxic. It is processed from ammonia and carbon dioxide in the liver.

    Sport persons and athletes should drink more and more water because water contains oxygen in it . As the sports persons do a lot of excercise and athletes run fast the demand of energy in their body is more and to fulfil the demand oxygen is necessary to produce energy. So, the oxygen dissolved in the water produces energy for the sports persons and athletes.

    Faraday’s First Law: Faraday’s First Law of Electromagnetic Induction states that whenever a conductor is placed in varying magnetic field, electromagnetic fields are induced known as induced emf. If the conductor circuit is closed, a current is also induced which are called induced current.

    Faraday’s Second Law: Faraday’s Second Law of Electromagnetic Induction states that the induced emf in a coil is equal to the rate of change of flux linkage. Here the flux is nothing but the product of number of turns in the coil and flux connected with the coil.

    The two main types of electrochemical cells are electrolytic cells and galvanic cells (also called voltaic cells). Electrolytic cells drive chemical reactions when electrical energy is applied to them, while galvanic cells use chemical reactions to generate electrical energy. Both types of cells have many useful applications.

    The biological process in which food is utilized to produce energy is called respiration. Respiration is necessary for survival of the living beings. A living being cannot survive even for a few seconds, without respiration. During respiration, it is mainly the carbohydrate which is oxidized to produce energy. This can be shown by following equation:

    Carbohydrate + Oxygen → Carbon dioxide + Water + Energy

    C6H12O6 + 6O2 → 6CO2 + 6H2 + Energy

    flower anatomy The Flower: The flower is the reproductive unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or more carpels (the female reproductive organs), and stamens (the male reproductive organs). The Female Reproductive Organs: The pistil is the collective term for the carpel(s). Each carpel includes an ovary (where the ovules are produced; ovules are the female reproductive cells, the eggs), a style (a tube on top of the ovary), and a stigma (which receives the pollen during fertilization). The Male Reproductive Organs: Stamens are the male reproductive parts of flowers. A stamen consists of an anther (which produces pollen) and a filament. The pollen consists of the male reproductive cells; they fertilize ovules.

    There are small openings on the lower surface of the leaves. These pores are called stomata. These openings are surrounded with guard cells.
    Functions of stomata:
    1. It helps in the transpiration of water, i.e., the loss of excess water from the plant.
    2. Loss of water from the stomata creates an upward pull, i.e., suction pull which helps in absorption of water from the roots.
    3. They help in exchange of gases.
