Anatomy and Physiology in Emergency Medical Services

These flashcards encompass fundamental concepts related to anatomy, physiology, and pathophysiology essential for emergency medical services.

Anatomy

The study of the structure of the body and its parts.

Physiology

The study of the function of the body's systems and their parts.

Pathophysiology

The study of how disease processes affect the function of the body.

Systemic circulation

The part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart.

Pulmonary circulation

The part of the circulatory system responsible for carrying deoxygenated blood from the heart to the lungs for oxygenation and returning oxygenated blood back to the heart.

Tidal volume

The amount of air moved into or out of the lungs during a single breath.

Systolic blood pressure

The pressure in the arteries during the contraction of the heart muscle.

Diastolic blood pressure

The pressure in the arteries when the heart is at rest between beats.

Epidermis

The outermost layer of skin, providing a barrier to the environment.

Endocrine system

A collection of glands that produce hormones regulating metabolism, growth, and development.

Homeostasis

The body’s ability to maintain a stable internal environment despite changes in external conditions.

Cranial cavity

The space enclosed by the skull that contains the brain.

Acidosis

A condition in which there is too much acid in the body fluids.

Alveoli

Tiny air sacs in the lungs where gas exchange occurs.

Hypoxia

A deficiency in the amount of oxygen reaching the tissues.

Shock

A critical condition that occurs when the body is not getting enough blood flow, leading to inadequate oxygen delivery to tissues.
