Anatomy and functions of Pancreas Essay

The earliest known description of the pancreas is attributed to Herophilus of Chalcedon (300 B.C.), a Greek physician deemed to be one of the first human anatomist and adopter of the scientific method (1). Despite Herophilus’s pioneering research on human anatomy, he received public criticism and was referred to as the ‘butcher’ of Alexandria – for his innumerable human dissections and gruesome vivisections performed before public audiences (2). The name ‘pancreas’ was later coined by Rufus (100 A.D.), another Greek physician, and etymologically translates as all flesh (pan: all, and kreas: flesh) – at the time the Greeks thought the pancreas was a fleshy cushion to protect the large blood vessels lying behind it (3). It wasn’t until the…

1.15E-Identify the basic function and organs of the urinary system and the digestive system The urinary system is made up of the kidneys, ureters, urinary bladder, and urethra. The urinary system’s basic function is to filter out waste and other materials from the bloodstream that are then transferred out of the system in the form of urine. Please refer to page 944 in the textbook for a complete picture diagram. • Kidneys: We normally have two kidneys; these kidneys measure 4 to 5 inches each.…

Introduction to Anatomy and Physiology Anatomy means the structure of the human body. Ana (making) Tomy (cutting.) Physiology means the study of normal human body’s functions. Physio (physical) Logy (study.) There are two different types of anatomy, which are Gross Anatomy and Microscopic Anatomic. Gross Anatomy refers to the structures that can be seen with the eyes. For example: the heart, the liver, and the kidneys. There are several subdivisions of Gross Anatomy such as; surface anatomy,…

before it passes through the other part of the body. It also detoxifies chemicals and metabolizes drugs (Hoffman). The right lobe is divided into four sections. Each section has branches of hepatic veins, portal veins, hepatic arteries, and bile ducts. If part of the section is damaged then the remaining sections of the right lobe of the liver will still continue to work. (Right Lobe of Liver Anatomy, Diagram & Function | Body Maps). Is the independent part of the liver which is supplied by…

different factors such as age, consumption of liquor. In this essay I will discuss how alcohol affects biological system of the body. Ethyl alcohol is rapidly absorbed into blood through stomach (smaller part of alcohol) and intestine (major part of alcohol). Firstly, long term use of alcohol affects the lining of gastrointestinal tract causes vomiting, diarrhoea, varices formation in oesophagus etc. Secondly, liver that is largest organ responsible for detoxification of alcohol but chronic…

Clearly stated in the dissection booklet it says “You will dissect a frog in order to observe the external and internal structures of frog anatomy, and therefore learn more about human anatomy.” We should be able to recognize both similarities and differences between human and frog anatomy, along with the functions of each organ. 2. A frog's tympanum is structured differently to adapt in its own environment otherwise water and other particles will end up entering the frog’s inner ears. Unlike…

The study of anatomy and physiology. Anatomy is the scientific term for the study of the body structure and physiology is the term for the study of the function of the body’s organs. During the class, we dissected a pig. We did it to compare the human body and its organ systems with the pig body because they are similar in function. We defined each system and the organs that belong to each one. In anatomy and physiology class we learn about the human body and its composition. To see and learn…

The major function of the large intestine is to absorb water and vitamins from the remaining indigestible food matter and transmit the useless waste material to the rectum. The large intestine can be separated into three different sections: the ascending colon, transverse colon, and the descending colon. The descending colon is connected to an S-shape figure known as the sigmoid colon and finally connected to the straightened canal of the rectum. The rectum function is to receive the stool…

Diabetes Mellitus The human body is a perfectly balance organism that needs to be in a state of homeostasis( balance) in order to function properly. Certain conditions however, can cause a disruption in the bodies equilibrium. Diabetes mellitus is a common disease that disrupts the bodies normal sugar levels leading to hyperglycemia (high blood sugar in the blood). There are 2 different types of diabetes mellitus; type 1 and type 2. Knowing the difference between diabetes type 1 and type 2 it’s…

Abnormal Anatomy and Physiology: In cystic fibrosis the CFTR gene does not produce the chloride pump protein, so water cannot move into the mucus making it very thick and sticky. This abnormally thick mucus builds up in passageways causing obstructions and harboring bacteria that cause infections, especially in the lungs and the pancreas. In the lungs this thick mucus leads to difficulty breathing and because of the bacteria that gets trapped and stuck in the mucus that lines the lungs people…
