is made up of two parts the Parenchyma and Stroma. The main functions of the liver are metabolism, vascular functions and secretory and excretory functions. The liver breaks down carbohydrates, fats and proteins. The end products are mostly stored in the liver and then used later when the body requires them. (2) The Vascular Functions is the formation of lymph and digestion of old red blood cells. The secretory and excretory functions include the synthesis and secretion of bile. (3) There are…
It has been noted that during breeding season, sharks will fast for an extended amount of time, and live off of lipids stored in their livers. Sharks do not necessarily require mating in order to reproduce, this type of reproduction is referred to as “parthenogenesis”. Shark’s senses are highly developed, most particularly their sense of smell which allows them to detect a subtle smell to its exact source. Shark’s sense of sight and hearing, although not quite as developed as their sense of…
tween 20. These solutions were absorbed at 540 nm and 640 nm. Table 2 shows the results of the red blood cells once they were submerged in different concentrations of NaCl and Tween 20. Something is said to be hypo-osmotic if the solution has fewer osmoles per unit volume when mixed with something else (Silverthorn, 2014). The solution in this experiment that was hypo-osmotic compared to the red blood cells was the 5% NaCl solution. When the cells were placed into this solution, they shrunk…
the common symptoms of type 1 diabetes. (Brown & Edward, 2012) DVT: Thrombosis is the homeostatic mechanism by which the blood coagulates or clots, an important process of hemostasis after the creation of the wound. Red blood cells, white blood cells, platelets are the sites of thrombus formation is the valve cusp of veins, venous stasis that allows the accumulation of blood products. The patient suffering from the symptoms of DVT or leg swelling, pain in extremity, skin redness and temperature…
two forms namely pigmented epithelial layer (PE) and non-pigmented epithelial layer (NPE). The anterior portion of CB continues with iris epithelium, posteriorly NPE continues with neurol retina and PE with retinal pigment epithelium. The important function of ciliary epithelium is to produce aqueous humor. Aqueous humor is required to build up the intraocular pressure (IOP), that maintains the eye shape, and also nourishes avascular eye tissues, like lens and cornea. Ciliary muscle helps for…
one body part to another body part Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component. The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious…
equilibrium even when faced with external environmental changes. This is achieved through either positive or negative feedback loop controls associated mainly with the endocrine and nervous systems. Principal homeostatic processes include regulation of blood pH, glucose, osmoregulation, and also temperature. Although some homeostatic mechanisms such as temperature control are unique to mammals and birds, all living organisms depend on effective internal regulation to some extent for survival. …
In her speech, The Ultimate Gift, Jennifer Conrad attempts to use Monroe’s Motivational Sequence in her speech to convince her classmates to donate blood regularly. She utilizes statistics and an anecdote to bring her point home. She provides the students with a clear way for them to help. Unfortunately, her condescending tone, lack of sensitivity towards a diverse audience, and lack of source citations reduced the effectiveness of her speech Overall I would not consider Ms. Conrad’s delivery…
red blood cells from the alveoli. The diffusion takes place because the PO2 in the alveoli is higher than that of blood (Pittman, 2011). This creates a pressure gradient that allows oxygen to diffuse into the capillaries in the alveoli. These capillaries have blood that has red blood cells that carries oxygen in two forms: dissolved in plasma and red blood cells water and bound to hemoglobin. The blood carried in hemoglobin accounts for 98%, of all oxygen in blood (Pittman, 2011). The blood…
The Ethics and Economical Aspects of Donating Blood Blood is a crucial part in many medical procedures and emergencies in which organizations such as the American Red Cross are constantly advocating the public to donate it. They advertise that while you are doing a simple task, you may be saving someone’s life. In a study done by Johanne Charbonneau, who has a Ph.D in political science and Natalie Y-Lang Tran, it was found that most people gave blood because they considered it a “useful”…
