Comprehensive 2026 ATI TEAS Review

A complete set of vocabulary flashcards covering key human anatomy, physiology, and cellular biology concepts from the Comprehensive 2026 ATI TEAS review.

Nervous System

The organ system responsible for transmitting nerve signals throughout the body.

Pulmonary Artery

The blood vessel that carries deoxygenated blood to the lungs.

Pulmonary Vein

The blood vessel that returns oxygen-rich blood to the heart.

Myocardium

The layer of the heart that contains muscle responsible for contractions.

Respiratory System

The body system responsible for gas exchange, including structures such as the lungs, bronchi, and trachea.

Alveoli

The structures in the lungs where gas exchange occurs.

Thalamus

The brain region that processes sensory information.

Parasympathetic Nervous System

The division of the nervous system that slows the heart rate.

Sinoatrial (SA) Node

The structure that acts as the heart's natural pacemaker.

Nervous Tissue

Specialized body tissue whose main role is transmitting electrical nerve signals and coordinating body communication.

Hypothalamus

The brain region that regulates pituitary hormone release.

Adrenal Gland

The endocrine gland that helps control blood pressure and the body's stress response.

Digestive Disorder

A disease or abnormal condition affecting the organs and structures of the digestive system.

Major Bone Types

The primary structural categories of bones in the human body, classified by shape into long, short, flat, irregular, and sesamoid bones.

Sesamoid Bones

Bones that are located embedded within tendons, such as the patella.

Ribosomes

Cellular organelles whose primary function is protein synthesis.

Cell Differentiation

The biological process by which generic cells undergo specialization to develop distinct structures and functions.

Mitochondria

The cellular organelle known as the powerhouse of the cell, responsible for producing ATP.

Mitosis and Meiosis

Processes of eukaryotic cell division that both require DNA replication prior to division and share stages of chromosome separation.

DNA Replication

The process of duplicating genetic material that must happen to DNA before cell division can take place.
