Human Body, Lab Equipment, and Daily Routine
Human Body
- Body: This term refers to the physical structure of a living organism, including humans. It includes all the organs, tissues, cells, and systems that work to maintain life and perform various functions.
- Brain: It is the complex organ that serves as the center of the nervous system.
- Heart: It is a muscular organ situated in the chest that functions as the central pump of the circulatory system.
- Liver: It is a vital organ situated in the upper right side of the abdomen. It plays an essential role in different metabolic processes of the body.
- Lung: It is a vital organ of the respiratory system situated in the chest cavity. Its function is to exchange oxygen and carbon dioxide between the air we breathe and the bloodstream.
- Muscle: Muscles are soft tissues in the body that are responsible for producing movement, maintaining posture, and generating heat.
- Injury: It is harm or damage caused to the body as a result of an accident, trauma, overuse, or other harmful events.
- Healthy weight: It is a weight range that is considered optimal for an individual’s height, age, gender, and body composition.
- Keeping fit: It refers to maintaining a level of physical fitness through regular exercise, healthy eating, and lifestyle habits.
- Breathing: It is the process of inhaling air into the lungs and exhaling it out.
Laboratory Equipment
- Microscope: It is an instrument used to magnify objects that are too small to be seen with the naked eye.
- Test tubes: They are cylindrical, transparent glass or plastic containers used in laboratories for holding, mixing, and heating small quantities of liquids or solids.
- Dropper: It is a small glass or plastic tube with a rubber bulb at one end that is used to transfer small amounts of liquid.
- Watch glass: It is a circular, slightly concave piece of glass that is used in laboratories for various purposes.
- Funnel: It is a conical or cylindrical utensil with a narrow tube at the bottom and a wide opening at the top, used for transferring liquids into containers with small openings.
Laboratory Safety
- Safety: It refers to the state of being protected from harm, danger, or injury.
- Corrosive: It refers to a substance that has the ability to cause damage or destruction to materials, living tissues, or the environment through chemical reactions.
- Toxic chemicals: They are substances that can cause harm, illness, or death when they are ingested, inhaled, or come into contact with the skin.
- Reagent: It is a substance or compound that is used in a chemical reaction to detect, measure, analyze, or produce other substances.
- Oxidizer: Also known as an oxidizing agent, it is a substance that has the ability to accept electrons from another substance in a chemical reaction.
Biological Samples and Concepts
- Biological samples: They refer to materials derived from living organisms that are used for scientific analysis, research, or diagnostic purposes.
- Cells: They are the basic structural and functional units of all living organisms.
- Tissues: They are groups of cells that work together to perform a specific function in an organism. In multicellular organisms, cells organize themselves into tissues to carry out specialized tasks efficiently.
- DNA: It is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all living organisms.
- Bioethics: It is a field of study that explores the ethical, legal, and social implications of advances in biology, medicine, and healthcare.
Skeletal System
- Bones: They are rigid organs that make up the skeletal system of vertebrates. They provide support and protection for the body’s organs.
- Cranium: It is the skull, the bony structure that encloses and protects the brain.
- Humerus: It is a long bone in the upper arm that extends from the shoulder to the elbow.
- Ribs: They are long, curved bones that form the rib cage which supports and protects the vital organs within, such as the heart and lungs.
- Backbone: Also known as the spine or vertebral column, it is a flexible and strong structure that runs along the center of the back and it is made up of a series of small bones called vertebrae.
My Daily Routine
In the morning, I wake up at 7:00 a.m. and get up quickly because I don’t like to stay in bed for too long. Then, I have breakfast, usually toast and coffee. After breakfast, I brush my teeth and take a shower. Once I am ready, I get dressed and prepare my things for the day. At 8:00 a.m., I go to school to study.
In the afternoon, I finish school and go home around 2:00 p.m. At home, I have lunch with my family. After eating, I sometimes take a nap for 30 minutes if I feel tired. If not, I spend my time doing the housework or my homework. This helps me stay organized and prepared for the next day.
In the evening, I like to do different activities. Sometimes, I go to the gym to do sport or go out with my friends for a walk. When I stay at home, I watch TV or read a book to relax.
At night, I have dinner with my family around 9:00 p.m. After dinner, I brush my teeth and prepare for bed. I usually go to bed at 11:00 p.m. and sleep well to feel ready for the next day.
