THE BIOLOGY CORNER

The human body is a complex machine, requiring many processes to function efficiently. To keep these crucial processes running without any hitches, vital elements and components need to be delivered to the various parts of the body. This role of transportation is undertaken by the human circulatory system, moving essential nutrients and minerals throughout the body and metabolic waste products away from the body.   The human circulatory system consists of a network of arteries, veins, and capillaries, with the heart pumping blood through it. Its primary role is to provide essential nutrients, minerals, and hormones to various parts of the body. Alternatively, the circulatory system is also responsible for collecting metabolic waste and toxins from the cells and tissues to be purified or expelled from the body. Features of Circulatory System The crucial features of the human circulatory system are as follows: The human circulatory system consists of blood, heart, blood vessels, and lymp

The respiratory system is a biological system that allows organisms to take in oxygen and expel carbon dioxide. It includes the organs and structures involved in breathing, which are responsible for exchanging gases between the body and the environment. The human respiratory system is responsible for facilitating the exchange of gases between the body and the environment. Its main function is to take in oxygen and expel carbon dioxide, which is a waste product of cellular respiration. Features of the Human Respiratory System The respiratory system in humans has the following important features: The energy is generated by the breakdown of glucose molecules in all living cells of the human body. Oxygen is inhaled and is transported to various parts and are used in the process of burning food particles (breaking down glucose molecules) at the cellular level in a series of chemical reactions. The obtained glucose molecules are used for discharging energy in the form of ATP- (adenosine trip
