Ischemia - Inadequate blood supply to an organ, especially the heart muscles, leading to tissue damage ATP - Adenosine triphosphate, a molecule that provides energy for cellular processes NaCl - Sodium chloride, commonly known as table salt and essential for various physiological functions Free radicals - Highly reactive molecules that can cause cellular damage and contribute to the development of diseases Cardiovascular disease - A range of conditions affecting the heart and blood vessels, including hypertension and ischemic heart disease Missense mutation - A genetic mutation that alters the amino acid sequence in a protein, potentially affecting its function Physiologic atrophy - The natural process of shrinking or wasting away of a body part or tissue, such as the thymus gland changes during childhood Mitochondria - Cellular organelles that generate energy and play a crucial role in metabolism DNA - Deoxyribonucleic acid, the molecule carrying genetic instructions for growth, development, and reproduction Type one diabetes mellitus - A chronic condition resulting from the pancreas producing little or no insulin, leading to high blood sugar levels Ribosomes - Cellular organelles responsible for protein synthesis Protein synthesis - The process by which cells generate new proteins, essential for various cellular functions Benign - A non-invasive growth that does not spread to other parts of the body Chromosomal abnormalities - Disorders caused by missing, extra, or irregular portions of chromosomal DNA, leading to genetic disorders Tumor necrosis factor alpha - A cell signaling protein involved in inflammation and immune system functions Interleukin one - A group of cytokines regulating immune and inflammatory responses Fertilization - The fusion of gametes to initiate the development of a new individual organism Genetic expression - The process by which information from a gene is used in the synthesis of a functional gene product RB one gene - A tumor suppressor gene controlling cell growth Mutation - A change in the DNA sequence of a cell's genome, leading to genetic variations Screening test - A test performed to detect potential health disorders or diseases in asymptomatic individuals Blood in the stool - A sign of potential health issues such as gastrointestinal bleeding or colon cancer Sex linked disorders - Genetic conditions caused by mutations in genes located on the sex chromosomes Tetratogenic agent - An environmental agent that can cause birth defects or developmental malformations in an embryo or fetus Messenger RNA - A type of RNA that carries instructions from DNA for controlling the synthesis of proteins Respiratory zone - The area of the respiratory system where gas exchange occurs, including structures like alveoli Dead space - The portion of the tidal volume that does not participate in gas exchange, affecting respiratory efficiency COPD - Chronic obstructive pulmonary disease, a group of lung diseases hindering airflow and breathing Pulmonary function testing - Tests measuring lung function and gas exchange efficiency Asthma - A chronic respiratory condition characterized by airway inflammation and narrowing, leading to breathing difficulties PaCO2 - Partial pressure of carbon dioxide in arterial blood, a measure of ventilation efficiency Acidosis - An excessively acidic condition of the body fluids or tissues, affecting various physiological processes Ectopic heartbeat - An irregular heart rhythm originating outside the heart's normal electrical system Angina pectoris - Chest pain due to inadequate blood and oxygen supply to the heart muscles ATP in cardiac muscle contraction - Plays a role in altering myosin affinity for actin binding sites, affecting the force of muscle contraction High heart rate - Leads to decreased cardiac output, affecting overall blood circulation Atherosclerosis - A disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls Fibrosis - The thickening and scarring of connective tissue, usually as a result of injury or chronic inflammation Neurological disease - A disorder affecting the nervous system, including the brain, spinal cord, and nerves Myelin basic protein - A major constituent of the myelin sheath, protecting and insulating nerve fibers
