The kidney is made up of nephrons‚ which are a kidney’s functional units. These nephrons collect fluid filtered from the blood. The kidney connects to the renal artery‚ renal‚ vein‚ and ureter. Purified blood leaves the kidney using the renal vein‚ urine leaves using a ureter and the renal artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the

The five major structures of the brain are myelencephalon‚ Metencephalon‚ mesencephalon‚ diencephalon and telencephalon. The myelencephalon carries signals from the brain to the entire parts of the human body and it is also uniquely shaped looking like a little net. The Metencephalon is made up of ascending and descending tracts just like the myelencephalon. It has two major divisions which are pons and the cerebellum. The mesencephalon has two divisions also and they are the tectum and the tegmentum

The Brain has five major structures . These structures include the mesencephalon‚ metencephalon‚ myelencephalon (or medulla)‚ telencephalon‚ and diecephalon. All of these brain structures contribute different functions within the human body. The brain’s first structure is the myelencephalon‚ which is also called the medulla. The myelencephalon is known as the most posterior part of the brain. The structure of the myelencephalon is made up of bundles of axons called tracts. These tracts carry

The major function of ball mill lining board is to protect the cylinder of ball mill from the direct clashing and friction of grinding media and material inside ball mill. Meanwhile‚ the ball mill lining board with different shape could be used to adjust the moving pattern of grinding media inside ball mill to strengthen the grinding effect of grinding media to material and increase the grinding efficiency of ball mill and output of ball mill. With the number of ball mill manufacturer’s increasing

The nucleolus (plural nucleoli) is a non-membrane bound structure. Composed of proteins and nucleic acids found within the nucleus. Ribosomal RNA (rRNA) is transcribed and assembled within the nucleolus. Three major components of the nucleolus are recognized: the fibrillar centers (FC)‚ the dense fibrillar components (DFC)‚ and granular components (GC). The DFC consists of newly transcribed rRNA bound to ribosomal proteins‚ while the GC‚ contains rRNA bound to ribosomal proteins that are beginning

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Bai‚ W.-G. Zhu]; Department of Biotechnology‚ Guilin Medical College‚ Guilin‚ China [L. Bai] Since the p53 tumor suppressor gene has been found to be mutated in more than 50% of human cancers‚ it has attracted the interest of numerous researchers. The capacity of p53 for multiple biological functions can be

Cell structure and function Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell‚ designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are tow major types of cells‚ prokaryotic cells and eukaryotic cells. An organelle is defined as an

Chapter 2 Integrin Structure and Function Manakan Betsy Srichai and Roy Zent Abstract Integrins are a large family of heterodimeric glycoprotein receptors first discovered over twenty years ago. They exist as two noncovalently bound a- and b- subunits that function as adhesion molecules and play key roles in many biological processes including actin cytoskeleton organization and transduction of intracellular signals regulating cellular functions. Integrins bind a variety of extracellular matrices

that of bacteria and manufacturing many of their own proteins. The fact that both the organelles reproduce by binary fission can also be mentioned. Besides the similarities between the two organelles‚ notable differences are present in their structure and function that could be stated as follows: Chloroplasts and mitochondria both have number of different membranes where most of the energy conversion reactions take place. But there are some membranes in the chloroplast that contain some crucial components
