Energy transformation Description Hibo Hussein Senior Seminar October 8, 2018 Dr.White Reflective Essay #1: Skill and Communication Outcomes In BIO129 had taught me the chemical foundations of life, it taught me the important elements and the percentage of it in our bodies like there are 65.0% air in our body and how carbon comes in second 16.5%. Another thing that I have learned is how I can is putting a Punnett square together (BIO129) it helped understand different the phenotype and genotype.BIOL0237 and BIOL039 introduced the concept of homeostasis and how positive and negative feedback loops were related. This includes an organism or cell regulate its internal environment and maintain equilibrium, by a system of feedback controls, to stabilize health and functioning. A set of chemical, thermal, and neural factors interact in complex ways; by both helping the body while it works to maintain homeostasis. This is also part of the nervous system for which nerve impulses are carried and passed through muscles or glands. In the endocrine system, hormones are secreted and stimulated by neurotransmitters and send cell signals through synapses of neurons. Triggering responses is also part of this concept where messages are sent to promote the start of a new process. Example of this is when mammary glands are triggered to produce milk for breastfeeding. The disease can also be triggered by specific proteins; the presentation I had done during my BIOL0180 class involved how proteins (their microspheres) could induce Glaucoma disease of the eye by increasing the eye pressure. In the presentation by Dr. Villeda, the communication between neurons in the brain was introduced and how it affects the aging of individuals. The stem cells don’t function when the brains are old and the communication between neurons decreases; and inflammation increases. A technique (Parabiosis) was used, according to Dr. Villeda, to investigate whether there is way to rejuvenate the brain, where a molecule called B2M used as a pro-aging factor. The immune system, as explained by Dr. Pouliot in BIOL0223, involves T-cells that recognize and respond to antigens that can be harmful to the body. Any substances on the surface of cells are caught by the immune cells and then receive messages to respond and take action in killing the harmful substances, such as viruses, fungi or bacteria. The immune cells ingest the invader during a process called phagocytosis and break it down. Phagocytic cells include neutrophils that are in the blood and can be called out to particular sites of infection and macrophages that can move throughout the body, but mostly in the spleen and lymph nodes where they could see a lot of action. Immune cells communicate either by cell-to-cell contact or through secreted signaling molecules, such as receptors and ligands.
