Blood flows through a closed system. Blood always travels through blood vessels except when it enters the chambers of the heart. When blood is pumped from the heart, it travels through five types of blood vessels – arteries, arterioles, capillaries, venules, and finally veins. Arteries are the first type of blood vessels that blood enters after being pumped out of the heart, and when the … Continue reading Blood Vessels
The fundamental characteristic of all living organisms is their use of energy to carry out life’s activities. Moving, growing, reproducing, and other cellular activities all require energy. The input of energy from the sun, and the transformation of that energy from one form to another is what makes life possible. For example, plants absorb energy from the sun through their leaves, but the energy does … Continue reading Transformation of Energy, Biological Systems, & Environmental Interactions
Neurons are the cells in our nervous system that are involved in signaling messages to the various parts of our body. Neurons have basic components that can be easily recognized; These components include the cell body, which is the cell’s control center, the dendrites, which receive messages from surrounding neurons, the axon, which runs away from the cell body and towards other cells, and the … Continue reading The Nervous System
Although there are many different kinds of neurons in the nervous system, the same basic electrical principles underlie their function. Before we can get into the complexities of neuronal signaling, let us take a look at the electrical principles that are in play when the cell is at rest. When you look at a typical neuron, you can see that it has a variety of … Continue reading Resting Potential & Voltage
The cardiovascular system is the system of blood circulation. The term cardiovascular, can be broken down into “cardio”, which means pertaining to the heart and “vascular”, which refers to the vessels of our body that contain fluid, specifically blood. Therefore, the cardiovascular system involves the heart, blood, the arteries, the veins, and the capillaries of the human body. It is crucial to understand that all … Continue reading Cardiovascular System
The cell is the smallest unit of biological organization that can perform all the activities necessary for life. In the 1830s, the famous cell theory was first developed by botanist Mathias Schleiden and zoologist Theodore Schwann. The theory states that all living organisms are composed of the basic units of life, cells, and all organism’s actions are propelled by the cell’s functions. For example, your … Continue reading Cellular Processes
Biopsychology is a branch of psychology that deals specifically with how the brain and neurotransmitters act upon the body, influencing what we do, say, and feel. In other words, it is the biology of the mind. This field leans heavily on neuroscience and includes the study of the nervous system. Anatomy, physiology, and statistics are also essential in the study of biopsychology. Understanding the nervous … Continue reading Neural Communication
Neurology is a very intriguing field of human anatomy and medicine that deals with the function, structure, influence, and disorders of the nervous system. To start off, the nervous system is the major control, regulatory, and communication system in the body. It is made up of a complex network of nerves and neurons that carry messages to and from the brain and spinal cord to … Continue reading The History of Bioelectricity
The extent of human knowledge has greatly increased over the recent years, with inquiring individuals making breakthrough discoveries in many fields. Despite their achievements and intellectual abilities, most people lack an understanding of their bodies, the structures within, as well as the collaboration between those various parts. As I take you on the journey to understand the “normal” human body, I will first cover the … Continue reading The Basics of Anatomy
Biology is the study of living organisms, including their interactions, chemical processes, physical structure, molecular workings, development, and evolution. Biology is such a broad field that it is broken down into several specific branches, such as microbiology, zoology, botany, anatomy, and physiology. Contemporary biological discoveries are being made every day, with each discovery bringing us as a society closer to understanding the secrets of biology, … Continue reading The Study of Life
