In this article we will discuss about the functions of human respiratory system. This article will also help you to draw the structure and diagram of human respiratory system. The human respiratory system is dominated by our lungs, which bring fresh oxygen (O2) into our bodies while expelling carbon dioxide (CO2). The oxygen travels from the lungs through the bloodstream [...]
In this article we will discuss about transposable elements in human. In human genome, two retro-transposons called LINEs (long interspersed sequences) and SINEs (short interspersed sequences) are found. LINEs are repeated sequences more than 5,000 bp long, interspersed among unique sequence DNA up to approximately 35,000 bp long. Full length LINEs are autonomous elements that encode the enzymes for their [...]
In this article we will discuss about the human excretory system with the help of suitable diagrams. The kidneys are bean-shaped (Fig. 12.1).The renal tissues are enclosed in a smooth, tough capsule. The renal tissues consist of an outer renal cortex and an inner renal medulla, several renal pyramids constitute the medulla. The base of a pyramid is placed outward [...]
