This deck covers key concepts and definitions from the ATI TEAS 2024-2025 Part 7, including topics in biology, chemistry, and anatomy.
Kinetic Molecular Theory
A theory stating that the molecules that make up all matter are in constant motion, and the temperature of a substance is directly proportional to the average kinetic energy of its molecules.

Long bones | Bones that have a pronounced longitudinal axis. |
Luteinizing hormone | A hormone secreted by the anterior pituitary that is responsible for triggering ovulation in ovaries, and the production of testosterone by testes. |
Lymph | Clear fluid that moves throughout the lymphatic system to fight disease. |
Lymphocyte | A category of white blood cells that includes natural killer cells, B cells, helper, T cells, and cytotoxic T cells. |
Lysosome | A cell organelle that aids in digestion and the recycling of old cell material. |
Macromolecules | Very large molecules, four major types of which are important to living things; carbohydrates, proteins, lipids, and nucleic acid. |
Macrophage | A large white blood cell that invests foreign material. |
Mass | A measurement of a inertia, commonly considered the amount of material contained by an object and causing it to have weight in a gravitational field. |
Mediastinum | The area between the two lungs. |
Meiosis | Specialized cell division used to create haploid gametes in diploid organisms. |
Memory cell | A lymphocyte that respond to an antigen join reintroduction. |
Mendelian inheritance | Inheritance of traits that follow Gregor Mendel's two laws and the principle of dominance. |
Metaphase | The stage in mitosis in which chromosomes align. |
Metaphase 2 | The stage in meiosis 2 in which individual chromosomes align. |
Metaphase 1 | The stage in meiosis 1 in which pairs of homologous chromosomes align. |
Microbes/microorganisms | Organisms that cannot be seen with the naked eye, and may be classified as bacteria, viruses, fungi, protozoa (including algae), or animals. |
Mitosis | Cell division in eukaryotes that produce two daughter cells, each with the same chromosome number as the parent cell. |
Molecule | An arrangement of two or more atoms bonded together. |
Monomers | Molecules that can bond to similar or identical molecules to form a polymer. |
Mouth | The oral cavity at the entry to the alimentary canal. |

Muscular system | An integrated system in the body that is vital for controlling, involuntary and voluntary movement. |
Mutation | A permanent change in the nucleotide sequence of DNA that may arise during replication. |
Negative feedback | A mechanism that includes the monitoring for specific homeostatic levels and signal to a gland. This signal stimulates or inhibits the glands secretion in order to maintain homeostasis or cause compensation that returns the level of homeostasis. |
Nephron | A system of microscopic tubes in the kidney that use various pressure levels to remove waste and reabsorb, important molecules, and water. |
Nerve | A long bundle of neuronal axons that transmits signals to, and from the central nervous system. |
Nervous system | A Complex system that controls and affects every part of the body in daily life functions, and in the constant drive to maintain homeostasis. |
Neutralization reaction | A chemical reaction in which mixing an acid with base causes the H+ from the acid to combine with the OH- from the base, forming water |
Neutron | An atomic particle with no electric charge. |
Non-infectious diseases | Diseases that cannot be transmitted directly from one person to another. |
