Describe the structure and function of a lysosome. Lysosomes are a cell organelle, translating as an independent structure within a cell, possessing a specific structure and function. For a lysosome its functions include; digestion of intracellular or extracellular material, nutrition from digested macromolecules and defence/protection from harmful substances. Lysosomes are variable from cell to cell in terms of shape and size but are conventionally spherical or oval shaped, 0.5µm in diameter…

arrangement of creases known as fraction ridges and they essentially comprise of pores. These pores are attached to the skins sweat or eccrine glands (Langenburg, 2014). Fingerprints are classified into three different categories which are commonly referred to as either patent, latent or impressed prints. Latent prints are created through the eccrine glands that produce amino acids,…

hypothalamus, pituitary gland, amygdala and the hippocampus, these are not all of the sections, but these are ones that are affected by mental illness. The hippocampus is in charge of emotions, and a chemical called dopamine exists within the brain, and it is in control of how happy or sad you are. The frontal lobe is in charge of your emotions, impulses, and it also controls your behavior. Your hypothalamus plays a huge role in what mood we are feeling. When the pituitary gland is injured you…

mind and body. For example; I should know when I am hungry or thirsty without needing a warning or being confused about it. Descartes’ says the pineal gland is where the confused or warning thoughts are housed (pg. 97-98 para 1). Descartes’ solution isn’t a solution because it raises the question of how do the mind and body interact in the pineal gland? Nagel illustrates the mind-body problem into his essay by saying if we can only see what it is like to be that organism through one view point…

affect the function of the salivary glands, limiting the secretory capability of the glands (Offenbacher, Southerland, & Taylor, 2005, p.174). Saliva is an important aid to oral health as it assists in neutralizing the acidic levels and wash away some bacteria that would otherwise adhere to the teeth’s dry surfaces. Xerostomia can also lead to enlarged parotid glands, inflammation of the lips, tongue and buccal mucosa (cheeks), infection of the salivary glands, halitosis (bad breath), and…

Describe (in your words) Schistosomiasis life cycle. Use the video in theme 1 as reference. Schistosomiasis is a parasite that penetrates the skin and enters the blood stream leaving behind its tail or known as cercariae form. The parasite then travels to the lungs for 4-6 weeks to mature. Once maturing for 4-6 weeks the parasite travels to the liver or sometimes heart to develop into adults male-female pairs. Once again, relocate to the preferred resting site, which varies based on species.…

Bullfrog Dissection Background The American bullfrog, Lithobates catesbeianus, is an amphibian about the size of a teacup.(National Geographic, “American Bullfrog”). This dissection explored the anatomy of a bullfrog that had been pithed. Pithing is a technique used to prevent the frog from experiencing any cruel or unusual pain during the dissection. A pithed frog has had its nervous tissue in its brain severed thus allowing it to maintain normal bodily function during the dissection without…

Enzymes are organic catalysts that speed up reactions that occur by lowering the activation energy of the reactants. By lowering the activation energy, the chemical bonds are weakened, thus the reactions are much faster than without the catalyst. Enzymes are composed of proteins which shape dictates the function of the enzyme. On the enzyme it contains a part called the active site where the substrate binds and the chemical reaction undergoes. A substrate is the chemical involved in the…

Facts About Cancer Pancreatic cancer is the fourth most common kind of cancers. Forty six thousand four hundred twenty people are diagnosed every year and Thirty nine thousand five hundred ninety people die every year. Cancer is the uncontrolled growth of cells that are able to avoid tissue. Cancer can spread throughout the body by using the blood and lymph node systems. There isn’t just one type of cancer, but over 100 different types of cancer. Most forms of cancer are named after where the…

Introduction The mammalian body contains many complex and interconnected systems. Each body system contributes a unique role to keep the mammalian body active and functional. However each body system relies on other body systems to perform their specific roles effectively. Muscular System The muscular system is responsible for the movement of the human body. There are more than 600 skeletal muscles within the body and this makes up 40% of a person’s body weight (Healthline, 2015). Muscle…
