Features of Lungs & Tissues

Authors Avatar
I am going to compare different tissues with similarities, including what cells are in the tissues and where they are located and what organelles are within the cells, also to state their functions including explaining how each tissue is able to carry out their role. Firstly I will compare (Alveolus of lung/Bronchus of lung), secondly (Stomach/Urinary bladder). Alveolus of lungBronchus of lungWhat cells are in the tissues?There are three types of cells within the tissue (Type I, Type II and Macrophages). Type I (Squamous Alveolar) cells that form the structure of an alveolar wall Type II (Great Alveolar) cells that secrete pulmonary surfactant to lower the surface tension of water and allow the membrane to separate, thereby increasing the capability to exchange gases. Surfactant is continuously released by exocytosis. It forms an underlying aqueous protein-containing hypophase and an overlying phospholipid film composed primarily of dipalmitoyl phosphatidylcholine. Macrophages that destroy foreign material, such as bacteria. Where they are located?Type II cell is located in the alveolar epithelium. Macrophage cell is found in the pulmonary alveolus, near the pneumocytes, but separated from the wall and type I cell is located beneath the plasmalemma.Main organelles within the cell?Organelles found within the cells are as

follows: Nucleus, Mitochondria, Lysosomes, Vacuole, Ribosomes and Cell membrane.Their function?Nucleus controls the cell’s activity. Mitochondrion produces energy. Lysosomes is capable of breaking down all types of biological polymers—proteins, nucleic acids. Vacuole is the storage. Ribosomes are the site of protein synthesis and Cell membrane controls what goes in and out of the cell.How they carry out their role?The alveolus receives blood from the circulatory system capillaries. It replaces carbon dioxide and other blood wastes with oxygen. The circulatory system then delivers the oxygen to cells throughout the body, bringing more wastes back to the lungs.What cells are in the tissues?The ...

Here's what a star student thought of this essay


Sometimes the grammar is incorrect resulting in the sentences sounding too short. Spelling, grammar and punctuation apart from this seems accurate.

The candidate states incorrectly that the bronchioles do not contain glands, when beforehand they stated that the bronchiole contains goblet cells, which are in fact a type of unicellular gland. The candidate does not clearly explain the function of surfactant in the lungs in relation to the anatomy, also it is the granular pneumonocytes which are the same as great alveolar cells and the candidate tries to distinguish these as two separate cell types. In the stomach the candidate misses out some cells such as the somatostatin producing cells. Also they wrongly refer to the fundus as the 'body' when in fact the body of the stomach is referred to as the corpus. The candidate could also have included more scientific information about the different cell types in the bladder.

Response to the question is presented to a good level. Some scientific information is missed or inaccurate in places, but mostly the candidate is correct. Their response is clearly presented in graphs. To improve the candidate could include deeper scientific information about each of the tissues studied.
