A collection of organs that transport blood throughout the body.
Cardiovascular System
Arteries, Capillary, and veins
Blood vessels
carries blood away from the body’s organs
Arteries
carries blood to the heart
Veins
tiny blood vessels that allows these exchanges between the body cells and blood
Capillary
Plasma, Platelets, Red blood cells, and white blood cells
Blood
fluid part
Plasma
help form blood clots and prevent bleeding
Platelets
carries oxygen to all cells in the body
Red Blood Cells
fights off pathogens
White Blood Cells
Left side, Right side, Atrium, Ventricle, Valves
Heart
pumps oxygen-poor blood to the lungs
Right Side
pumps oxygen- rich blood to the body
Left Side
has an upper chamber called the atrium and a lower chamber called the ventricle
Each Side
located between the atria and ventricles and in places where large arteries attach to the heart
Valves
flow of blood from the heart to the lungs and back to the heart.
Pulmonary Circulation
flow of blood form the heart to all parts of the body and back to the heart.
Systemic Circulation
Strong jaws and teeth break and grind food, Saliva contains enzyme that begins chemical digestion of carbs, Esophagus uses rhythmic muscle contractions to force food into stomach.
Mouth
Food is squeezed and broken into nutrients by a bunch of enzymes and acid (creates chyme)
Chyme is released slowly into small intestine through a small ring of muscle.
This allows more time for the chyme to mix with fluids from the liver and pancreas.
Stomach
Pancreas produces fluid (enzyme) that neutralizes acid in chyme
VillI are located inside the small intestine wall
Villi are covered with nutrient absorbing cells that pass nutrients into the bloodstream.
Pancreas and Small Intestine
The liver creates bile to break up fat, stores nutrients, breaks down toxins
Bile is stored into the liver and squeezed into the small intestine to break down fat droplets
The liver releases nutrients into the bloodstream when needed.
Gallbladder does similar things
Liver and Gallbladder
Large Intestine absorbs water in the mixture and changes it to feces
Fiber in food (whole grains, fruits, and vegetables) keeps feces soft
Rectum stores feces until ready to expel and pass it through small opening called anus
Large Intestine and Beyond
6 major Nutrients
Carbohydrates, Fats, Proteins, Vitamins, Water, Minerals
The enzymes break down food into smaller molecules
Chemical Digestion
