Circulatory System Reflection

Dear fellow followers,

This week Mr. Wan taught us about the circulatory system. The circulatory system is an organ system  that permits blood and lymph circulation to transport things such as nutrients, oxygen, carbon dioxide, hormones, blood cells, etc. to and from cells in the body. We mainly talked about the heart and blood vessels and how they work. We also went further in depth and talked about the arteries, veins, and capillaries. The circulatory system is a very interesting topic and very important as well.

Body System

To my followers,
 In class this week, our proffesor wanted us to research one of the seven organ systems. I researched the excretory system. The excretory system is a passive biological system that removes excess, unnecessary materials from an organism, so as to help maintain homeostasis within the organism and prevent damage to the body.  When we sweat, urinate, and even bleed sometimes, we are using our excretory system.

Body Systems Reflection

Dear fellow followers,

To start off our journey through physiology, we learned about the eleven body systems. The eleven groups of three that we split up into were each given a body system to research, my group was given the excretory system. The excretory system is made up of the skin, lungs, and kidneys- along with their associated organs. The kidney plays the biggest role in this system. As waste-laden blood enters the kidney and travels through it, urea, excess water, and other waste products are removed and collected as urine. The clean, filtered blood is then returned to circulation through the renal vein. The kidneys also play an important role in maintaining homeostasis. They regulate the water and therefore, blood volume, maintain blood pH, and remove waste products from the blood. If anything happens to the kidneys serious medical problems will soon follow.

Week 13 Reflection

Our dive into Physiology began with an introduction to the eleven body systems. Groups of three were assigned a body system to research, and my group was given the Respiratory System. The respiratory system is very closely linked to breathing. There is approximately 1500 miles of airway. Also, one's right lung is larger than their left lung because of the heart and its positioning. The respiratory system allows people to breath 10 liters of air in a single minute. Although many people do not know this, people are capable of living with only one lung. Simple exercise can improve lung capacity. Up to 300 million alveoli can be found in a pair of lungs. The respiratory system is one of the multiple body systems that make human life possible.

Week 9 Reflection

To whom this may concern,

This week in Biology we learned about ecology. Ecology is the study of the interactions between organisms and their environment.  Observing, experimenting, and modeling are methods used by scientists to study the biosphere.  Also, the nitrogen, carbon, water, and phosphorus are the four cycles of matter.  Another thing we learned is that energy flows through an ecosystem.  It flows in one direction from autotrophs to heterotrophs.  Autotrophs, or producers, get their energy from the sun, and heterotrophs, or consumers, get their energy from producers.

Week 9 reflection

Dear fellow followers,

This week our class learned about ecology. Ecology is the study of interactions between organisms and their environment. Scientists use the studying methods of observing, modeling, and experimenting to further understand the biosphere. Along with ecology, Mr. Wan also taught us about the flow of energy. We learned about food chains and food webs, and how energy flows in one direction from producers to consumers. Producers, also know as autotrophs, obtain energy directly from the sun. Consumers, or heterotrophs, get their energy from other organisms. We also learned about the cycles of matter. The cycles include the water, carbon, nitrogen, and the phosphorous cycles. #bloggin

Week 9 Reflection

Ecology is the study of interactions betweens organisms and their surroundings including other organisms and the environment. Scientists study the biosphere and other phenomenas on earth by observing, experimenting, and modeling. Next, I was taught that energy moves in one direction from producers to consumers. Producers are organisms that obtain energy by producing their own food. They are also known as autotrophs. Consumers get their energy from other organisms. Consumers are either herbivores(only plants), carnivores(only meat), or omnivores(both).This week I also learned about the numerous cycles of matter, and that matter is never lost or produced. These cycles include the water cycle, the nitrogen cycle, the carbon cycle, and the phosphorus cycle.
