Working of the heart

                           WORKING OF HEART   Blood from different parts of the body comes to right atrium, when it expands. Blood is brought from upper part of the body through superior vena cava and from lower part of the body through inferior vena cava.  When right atrium contracts, the blood goes to right ventricle. The atrioventricular aperture is closed by a valve after blood transfer. Valves prevent backflow of blood when the atria or ventricle contracts.    When the right ventricle contracts, blood forced out to the lungs for oxygenation through pulmonary artery, guarded by another valve. In lungs the exchange of gases takes place, blood give off carbon dioxide and takes in oxygen from lungs. Pulmonary vein brings oxygenated blood from lungs to the left atrium, as it relaxes. When the left atrium contract, the blood is transferred to left ventricle, which expands. The aperture between left atrium and ventricle is guarded by another valve. The wall of ventricle is three or

Neuron Structure And Functions

          NEURON STRUCTURES AND FUNCTIONS     Functions of nervous system:- 1. Sensory input, that is, the detection of stimuli by the receptors or sense organ. 2. Transmission of nerve impulse to brain or spinal cord, which generates appropriate response. 3. Motor output, that is, carrying out of response by muscles or glands, which are called effectors. Two types of cells constitute our nervous system. One is neuron and another is neuroglia. Neuron conducts impulses and neuroglia provides support and protection to neuron.  A neuron consists of a cell body called cyton and two processes dendrites and axon.     Dendrites:- Dendrites are hair like extensions connected to cyton. They receive stimulus, which may be physical, chemical, mechanical or electrical and passes it to cyton.   Cyton:- It is the cell body with a central nucleus which is surrounded by cytoplasm.   Axon:- From one side of the cyton arises a cylindrical process filled with cytoplasm. It is called axon.

Response And Coordination In Plants

                       RESPONSE AND COORDINATION IN PLANTS  Plants movements  Tropic movement:-  The movements of organism in the direction of stimulus or away from stimulus are known as tropic movement or tropism.  It is positive if directed towards the source of stimulus and negative if directed away from stimulus.  Different types of tropic movements:-  Phototropism:- The tropic response of organism to light is called phototropism. If a young green plant takes light from one direction only, it bends towards the light source. So, the stem said to be positively phototropic.  Geotropism:- The tropic response of organism to gravity s called geotropism. If a growing region of plant placed horizontally, the stems tips grow away from pull of gravity while the root grows in direction of gravity. The stem is negatively geotropic and the root is said to be positively geotropic.  Hydrotropism:- The growth of plant part towards or away from water is known as hydrotropism. The
