Anatomy

mouth

(respiratory system) the opening through which air enters the body; it is involved in the processes of respiration.

Larynx

(respiratory system) the organ responsible for producing sound and protecting the trachea

epiglottis

(respiratory system) a flap of tissue that covers the larynx during swallowing to prevent food and liquid from entering the airway.

pharanx

(respiratory system) the muscular tube that connects the mouth and nasal cavity to the larynx and esophagus, facilitating both breathing and swallowing.

nasal cavity

(respiratory system) the air-filled space behind the nose that helps filter, warm, and moisten air before it enters the lungs.

trachea

(respiratory system) the tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

lungs

(respiratory system) the organs used for breathing, facilitating gas exchange of oxygen and carbon dioxide.

bronchi

(respiratory system) the major air passages that diverge from the trachea and direct air into each lung.

bronchioles

(respiratory system) the smaller air passages that branch off from the bronchi and lead to the alveoli for gas exchange.

alveoli

(respiratory system) the tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

diaphragm

(respiratory system) a dome-shaped muscle that separates the thoracic cavity from the abdominal cavity, playing a crucial role in breathing.

Vena cava

(circulatory system) the large vein that carries deoxygenated blood from the body back to the heart.

Pulmonary artery

(circulatory system) the artery that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

right atrium

(circulatory system) the chamber of the heart that receives deoxygenated blood from the body through the vena cava before pumping it into the right ventricle.

right ventricle

(circulatory system) the chamber of the heart that receives deoxygenated blood from the right atrium and pumps it into the pulmonary artery.

pulmonary artery

(circulatory system) the blood vessel that transports deoxygenated blood from the heart to the lungs.

pulmonary vein

(circulatory system)the blood vessel that carries oxygenated blood from the lungs to the heart.

left atrium

(circulatory system) the chamber of the heart that receives oxygenated blood from the lungs through the pulmonary veins and pumps it into the left ventricle.

left ventricle

(circulatory system) the chamber of the heart that pumps oxygenated blood into the aorta for distribution throughout the body.

aorta

(circulatory system) the largest artery in the body, which carries oxygenated blood from the left ventricle to distribute it to the rest of the body.

esophagus

(Digestive system) the muscular tube that connects the throat to the stomach, transporting food and liquids.

bile duct

(Digestive system) creates bile

stomach

(digestive system) stores food, mixes it with digestive juices, and starts protein digestion

pancreas

(Digestive system) provides enzymes and regulates blood sugar with hormones

small intestine

(Digestive system) digests and absorbed nutrients from food

large intestine

(Digestive system) absorbs water and electrolytes from undigested material, forming solid wastecolo

colon

(Digestive system) solid waste is stored and then eliminated from the body

liver

(Digestive system) produces bile and filters nutrients from small intestine

gallbladder

(Digestive system) stores and concentrates bile production and releases it into the small intestine.

duodenum

(Digestive system) further breaks down food from the stomach

appendix

(Digestive system) useless

kidney

(excretory system) filters blood and removes urine

skin

(excretory system) expells waste through sweat

lungs (ex)

(excretory system) remove CO2 from the body

liver

(excretory system) processes toxins

brain

(nervous system) control senter of the nervous system

nerves

(nervous system) transmit electrical and chemical signals between brain and spinal chord

spinal chord

(nervous system) relays signals between the brain and the peripheral nervous system and controls nerves
