Introduction to Cell Tissue and Organ

My deep rooted curiosity about the human body is what has driven me to study this course. Contributing to future medical developments, as well as breakthroughs in wider science, is something that both excites and motivates me. This fascination surrounding the body works has led to an enthusiasm for science, particularly Biology, that extends beyond the classroom.

I have always had an interest in the human body and animal anatomy. I've studied it on my own with coloring books, online programs and thru home dissection kits. It is fascinating to learn the numerous ways our bodies function. I completed an anatomy and physiology course through our home school coop. I learned a lot of important information that will help me advance in my education and career.

Cells: Biology. a usually microscopic structure containing nuclear and cytoplasmic material enclosed by a semipermeable membrane and, in plants, a cell wall; the basic structural unit of all organisms

Dissecting helps students appreciate the complexity of organisms, by actually being able to come in contact and see up close instead of learning about it through a textbook. Students will become more involved if they are able to do something, rather than just listen as they will mostly not retain anything. Therefore, speaking from experience the dissection is geared more for hands- on learners, but, it enables all students to practice their observational and following instruction skills. Comparing notes with other students this dissection enabled everyone to come up with a better visualization of how all the organs are interconnected in the human body. Looking through the textbook at pictures does not give an

In a classroom setting, each student has a different way of learning. Physical and visual learning. Performing dissections enables those that are aimed more towards physical learning to get a more hands-on experience and to get a feel of the different textures, whereas the visual learners can get a three-dimensional imagery of the different systems and how they are arranged to work together.

Cells are the basic units of structure and function in an organism, and Cells come only from the reproduction of existing cells.

Students will receive direct instruction during a lab which covers the different parts of a microscope, and the functions that each part cover. After direct instruction, the teacher will model how each part of the microscope functions, after which the students will discuss among small groups how the microscope works, then demonstrate within small groups how to use a microscope. During this time, the teacher will move around the student lab stations and assist students in further understanding of the functions of a microscope.

is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It is composed of a thin, double-layered sheet of lipids, around the Cell and is a protective membrane layer around every Cell.

Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.

Epithelium – Epithelium tissues are composed of layers of the cells that are closely packed together which is specialised to form the covering or lining of both external and internal surface of body such as surface of your skin and internal digestive system. The main function of epithelium tissues are to provide protection like skin that protects you from injury, secretion like glands such as enzymes, and to absorb materials like intestine such as waste products etc.

To learn how concentration of reactants and products change with time and to distinguish (based on the trend) the order of the reaction.

Transitional epithelium is also composed of several layers but is constructive of pear shaped cells instead. This type of tissue is stretchy, meaning it can contract and expand. It is usually found lining the urinary bladder as it allows for stretching as the bladder fills up.

The nurse at times must review anatomy and physiology of body systems and landmarks. I had to review the body's anatomy and landmarks several times during this class and it was very helpful. I found the Shadow Health visual program a useful tool in my completion of this course. The program made me feel like I was actually in the room with the patient performing the assessments. It is a very good program and an asset to this course.

One of the most amazing moments of that class was the chance that I had to visit a human anatomy lab at a local college. There college students showed us the cadavers they had been working on, allowing us to see the human body up close and personal. I saw the difference between a smoker’s lung and a non-smoker’s lung, exactly how a knee replacement works, and other insights to the human body.

The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell, which are categorized according to the way their genetic material is packaged, rather than size or shape. These are:
