Body systems

EMT

Hypothalamus

Located in brain, connects nervous and endocrine system, controls pituitary gland

Pituitary gland

Small gland at the base of the brain, known as the "master gland" because it regulates various hormones and controls other endocrine glands.

Thyroid gland

A butterfly-shaped gland located in the neck that produces hormones regulating metabolism, growth, and development.

Parathyroid gland

Small glands located behind the thyroid that regulate calcium levels in the blood and bone metabolism.

adrenal gland

Located on top of the kidneys, these glands produce hormones such as adrenaline and cortisol that help regulate metabolism, immune response, and stress.

pancreas

A gland located in the abdomen that produces insulin and digestive enzymes, playing a crucial role in regulating blood sugar levels and digestion.

ovaries(female)

The female reproductive glands that produce eggs and hormones such as estrogen and progesterone, essential for reproductive health.

testes(male)

The male reproductive glands responsible for producing sperm and hormones, including testosterone, which play a vital role in male reproductive health and secondary sexual characteristics.

Pineal gland

A small gland in the brain that produces melatonin, regulating sleep-wake cycles and influencing reproductive hormones.

kidneys

Organs that filter blood, removing waste and excess substances to produce urine, while also regulating blood pressure and electrolyte balance.

Integumentary system

The system that includes the skin, hair, nails, and associated glands, serving as a protective barrier and regulating temperature and sensation.

renal system

The organ system responsible for the production of urine, elimination of waste, and regulation of blood volume and pressure, primarily involving the kidneys, ureters, bladder, and urethra.

bladder

A hollow muscular organ that stores urine until it is excreted from the body.

digestive system

The organ system responsible for breaking down food, absorbing nutrients, and eliminating waste. It includes the mouth, stomach, intestines, and associated glands.

esophagus

A muscular tube that connects the throat to the stomach, transporting food and liquids during swallowing.

mouth

The first part of the digestive system where food enters; involved in chewing and saliva secretion.

stomach

The organ that holds food while it is being mixed with stomach enzymes and acids, further breaking it down before passing it to the small intestine.

small intestine

The digestive organ where most of the digestion and absorption of nutrients occurs, following the stomach.

liver

A large organ that processes nutrients from the small intestine, produces bile, and detoxifies harmful substances.

anus

The final section of the digestive tract, through which waste leaves the body.

rectum

The final section of the large intestine that stores waste before it is expelled from the body.

skeletal system

The organ system that provides structure, support, and protection to the body, consisting of bones, cartilage, and ligaments.

Nervous system

The body's control network, transmitting signals throughout the body.

Neurological dissorder

Mental disease

Peripheral nervous system

Connects brain and spinal cord to limbs and organs

Sensory/Motor nerves

Hands and feet

automatic nervous system

a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal

Circulatory system

Transports oxygen, nutrients, and hormones while removing waste

blood vessels

tubes that transport blood

heart

Pump for your blood in the body

Automaticity

Ability to function automatically without instruction

Blood

Contains Plasma, RBC, WBC, Platelets

Blood pressure

The pressure of blood in the circulatory system

systolic

Upper reading of BP

diastolic

Lower reading

Respiratory system

System for gas exchange: takes in oxygen, releases carbon dioxide

Larynx

Part for gas exchange. Oxygen in, carbon dioxide out.

Cricoid cartilage

The cricoid cartilage, located in the larynx, is a complete ring of cartilage that maintains airway patency and serves as an attachment point for muscles and ligaments involved in vocalization and respiration

Trachea

Ring of cartilage that maintains airway patency and muscle attachment for vocalization and respiration.

Lungs

Primary organs for gas exchange in the respiratory system.

Bronchi

Airways branching from the trachea into the lungs

Alveoli

Air sacs for gas exchange in the lungs

Diaphragm

Primary muscle for breathing

Inhalation

Breathing in; an active process.

intercostal

Muscles between ribs aiding breathing

Exhalation

Passive process, Breathing out

Ventilation

movement of gases to and from alveoli

respiration

exchange of gas between cells and blood stream
