Digestion
This is where most of the wastes in our digestive system come from
Food
Eight structures that help you breathe (IN ORDER)
nose/mouth > nasal cavity > epiglottis or larynx(voice box)> trachea/windpipe > bronchial tubes > bronchioles > alveoli (lungs/ribs/diaphragm, etc.)
Kidneys filter waste from _______
blood (blood cells)
How is the circulatory system helpful in cellular respiration
transport blood cells t/o body taking in O2, taking out CO2
This organ absorbs the most nutrients, you just can't live without it
Small intestine
This type of digestion breaks nutrients down into different substances our body can use
Chemical Digestion
How does the circulatory system help cellular respiration?
Carries O2 to blood cells > turns into CO2
Tubes that carry waste from kidneys to bladder
Ureters
Tiny blood vessels that are so small red blood cells have to pass through one by one
Capillaries
This organ is what would get removed in a gastrectomy
The stomach
The process of mechanical digestion by contractions and relaxation of intestinal muscles
Peristalsis
As you breathe in your lungs _____ and your diaphragm ______
Expand / Contracts
The purpose of the urethra
excretes waste from kidneys
The term cardiovascular comes from "cardio" meaning ____ and "vascular" meaning _____
Heart/Vessels
These can be found in the small intestine to allow broken down nutrients to be absorbed into the bloodstream
Villi
Two examples of how your body performs mechanical digestion
peristalsis and chewing
This body waste serves an important purpose to keep bacteria out of your airway
Mucus
Looping tubes in the kidneys that regulate blood
Nephron
What is happening to blood cells when you have high blood pressure?
The cells swell up causing more pressure on the vessels
In which order would food pass through the large intestine, esophagus, small intestine, mouth, and stomach?
Mouth, Esophagus, Stomach, Small/Large intestine
Two examples of how your body performs chemical digestion
The two main substances expelled from the lungs as you exhale
H2O and CO2
The two main substances expelled from your kidneys as wastes
H2O and NaCl
Two systems that remove wastes from blood
Urinary (liquid) / Respiratory (gases)
(In order) Which enzymes breakdown fats, proteins, and starches?
Lipase, Protease, and Amylase
Why is the digestive process important in the respiratory process
the digestive process provides the sugars needed for cellular respiration:
C6H12O6 + 6O2 > 6CO2 + 6H2O
This structure blocks your airway as you swallow food
Epiglottis
Some people who are lost in deserts often die from this condition while holding what they need to survive
Dehydration
The U.S. organization focused on cardiovascular health
American Heart Association
This is the liquid waste that comes from your integumentary system
Sweat (from your skin)
