CHARACTERISTICS OF LIFE
Physiologists may list different qualities of life based on the type of organism being researched and the way life functions are organised and defined. The characteristics that define life in microbes, plants, and mammals can differ. The following are the ones that are thought to be the most essential in humans.
Responsiveness: The capacity of an organism to perceive, monitor, and respond to changes in its external environment is known as responsiveness or irritability. Responsiveness is defined as the ability to withdraw from a painful stimuli, such as a pin prick.
Conductivity: The ability of living cells and tissues to selectively transfer or propagate a wave of excitation from one location to another inside the body is referred to as conductivity. Both nerve and muscle cells in live beings have highly developed responsiveness and conductivity.
Growth: Growth is the consequence of a natural rise in size. in cell size or number In the majority of cases, it results in a rise in the size of an individual or a specific organ portion, but there is minimal change in the overall structure of the organism entire or of the afflicted portion
Respiration: Respiration refers to the mechanisms that cause an organism to absorb, transport, use, or exchange respiratory gases (oxygen and carbon dioxide) with its surroundings. Internal respiration is the exchange of gases between the blood and individual body cells as the cells use nutrients to create energy, or between the blood and air in the lungs (external respiration).
Digestion: Digestion is the act of breaking down complex foods into simpler chemicals that may be absorbed and utilised by specific body cells.
Absorption: The passage of digested nutrients past the wall of the digestive tube and into bodily fluids for delivery to cells for utilisation is referred to as absorption.
Secretion: Secretion involves the creation and distribution of specific chemicals for various physiological processes, such as digestive juices and hormones.
Excretion: Excretion is the process of removing waste products created during a variety of bodily activities, such as the breakdown and use of nutrients in the cell. Carbon dioxide is a gaseous waste product that is expelled when breathing.
Circulation: Circulation is the flow of bodily fluids and a variety of other things from one body region to another, including nutrients, hormones, and waste products.
Reproduction: Reproduction include the creation of a new individual as well as the creation of new cells (through cell division) in the body to allow for growth, wound healing, and the regular replacement of dead or aged cells. Each "characteristic of life" is connected to the sum of all physical and chemical events that take place in the body. These several processes are referred to as metabolism. They include the procedures involved in converting one substance into another and breaking down nutritional resources to create energy. If we eat and absorb more sugar than our bodies require for immediate energy, it gets transformed to an other form, such as fat, which can be stored in the body.
