Hence, they require more O 2 for more respiration so that they can produce more energy to maintain their body temperature. This efficient system of oxygen supply is very useful in warm-blooded animals such as human beings.Īs we know, warm-blooded animals have to maintain a constant body temperature by cooling themselves when they are in a hotter environment and by warming their bodies when they are in a cooler environment. The separation of oxygenated and de-oxygenated blood allows a more efficient supply of oxygen to the body cells. Therefore, the blood goes twice through the heart. Schematic diagram of blood circulation in humans The aorta gives rise to many arteries that distribute the oxygenated blood to all the regions of the body. The blood passes to aorta from the left ventricle. Then the left atrium contracts and through the auriculo-ventricular aperture, the oxygenated blood enters the left ventricle. From the lungs, the pulmonary veins transport the oxygenated blood to the left atrium of the heart. Then the right ventricle contracts and passes the de-oxygenated blood into the two pulmonary arteries, which pumps it to the lungs where the blood becomes oxygenated. The right atrium then contracts and passes the de-oxygenated blood to the right ventricle, through an auriculo-ventricular aperture. The topics discussed in the chapter, Life Processes are - What are Life Processes?, Nutrition, Respiration, Transportation and Excretion. Additional information on artificial kidney and organ donation is also provided in the chapter, Life Processes. The entire mechanism of excretion in humans is discussed with the help of a suitable diagram. Similarly, the process of transportation of water, food and other substances in plants is also explained. A schematic sectional view of the human heart along with the transportation and exchange of oxygen and carbon dioxide in the human body is presented in the chapter. Subsequently, the process of transpiration is dealt with in detail. A schematic view of the human respiratory system is covered in the chapter. The breakdown of glucose by various pathways in the human body is discussed. The process of respiration is also explained in detail in the chapter, Life Processes.
Additional information on dental caries is also provided in the chapter. The process of nutrition in amoeba and human beings is described along with their schematic view. It also talks about the important factors essential to bring about the process of photosynthesis. The diagrammatic representation of the cross-section of the leaf and the open and closed stomatal pore is included under the autotrophic mode of nutrition. The following two modes of nutrition in living organisms are discussed:
The process of nutrition is covered in detail along with its related concepts. Also, the importance of various organs involved in carrying out significant life processes is also taken into consideration. The term life processes is defined in the chapter.
