food

Made with thick muscle and has 4 chambers,right atrium,right ventricle,left atrium,left ventricle.pumps oxygenated blood from lungs to all body cells,pumps deoxygenated blood from body cells to lungs,has valves to prevent backwards flow of blood.

carry blood away from heart,specifically from from the left ventricle.pulmonary arteries-carry deoxygenated blood from heart to each lung,specifically from the right ventricle.Aorta-carries oxygenated blood from heart to other arteries in the bodystrong thick elastic walls withstand high pressure

smaller branches off arteries,leading to capillaries

carry blood toward the heartpulmonary vein-carries oxygenated blood from lungs to heart Vena Cava-carry deoxygenated blood from body cells to heart specifically to the right ventricle.thinner walls than arteriesvalves prevent backward flow of blood

smaller branches of veins,leading to capillaries

Physical/chemical breakdown,salivary enzymes

bites food into smaller pieces to go down esophogus

smooth muscleperistalsis wave like muscular contraction,moves bolus

pharynx is shared by digestive/respiratory system divides into the esophagus or trachea.

long tubeair passes through into lungs lined with cartilage to keep airway open mucus and cilia protect

muscle between esophogus and stomach.opens to allow bolus to enter stomach stays closed to prevent stomach acid from bubbling up into the esophogus.

epiglottis-directs food into esophagus and protect the trachea

physical=paristalsis,chemical=HCI(aq),smooth muscle,mucus lining,chyme

chemically breaks down foodmoistens your mouth, reduces infections in the mouth and throat, and helps protect your teeth and gums.

helps break down food

The liver processes blood, breaking down the nutrients and chemicals your blood carries. produce bile

stored bile

digestive chemicals are injected into the duodenum from accessory organs.bile made from liver and stored in the gall bladder breaking down into smaller pieces (Pancreatic juices).

Nutrients in intestine,diffuse through the villi,capillaries,cells of the body

peristalsis;long,coiled tube,villi,High SA,low V,thin membrane,capillary;duodenum,jejunum,ileum,The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients 

Nutrients in intestine,diffuse through the villi,capillaries,cells of the body

paristalsis;long tube,water absorbed through osmosis,dehydrates chyme and forms into stool absorbs water through osmosis,absorbs electrolytes,bacteria breaks down into waste(chemical)

feces(undigested materials)are stored in the rectum and eliminated through the anus.

produce insulin,enzymes,neutralize chyme

disposes feces at end of cycle

inhales air nose hairs and mucus trap dirt and other particles strong cartilage to keep airway open

contains vocal cordsair causes vibration to create sound

two branches airways leading to each lung also lined with cartilage

smaller and smaller branches leading to alveoli

Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.

two branches airways leading to each lung also lined with cartilage

smaller and smaller branches leading to alveoli

tiny branches of arterioles & venules,surrounding tissueseasy diffusion of O2,CO2,glucose,other nutrients & wastesone cell thickmillions of themcover almost all the tissueshigh surface area,low volume

flexible tiny air sacs at the end of bronchioles,walls are one cell thick,surrounded by capillaries (circulatory system)allows for easy diffusion for gas exchange.
