Circulatory/respiratory systems Flashcards
Carries oxygenated blood away from the heart
Artery
Thick walls because this blood vessel is under high pressure
Artery
Thinner walls because this blood vessel is under low pressure
Veins
Brings deoxygenated blood back to the heart
Vein
Blood vessels that are on cells thick
Capillaries
wraps alveoli so gas exchange can take place
Capillaries
walls in the heart that separate oxygenated blood and deoxygenated blood
Septum
Large, irregularly shaped cells with a nucleus
White blood cells
What’s the function of the blood cells that have a nucleus?
to fight infections
Found in blood, create a web to clot
platelets
O shaped blood cells with no nucleus that carries Oxygen to body cells
Red blood cells
Hemoglobin is important because it is an —- rich pigment
iron
lower two chambers of the heart
ventricles
Upper 2 chambers of the heart
atria
Deoxygenated blood enters into the —- side of the heart
RIght
Blood goes from the lungs into the —– side of the heart
Left
Blood —- the —– when the heart contracts
exits, ventricles
When the heart relaxes, blood ____ the ______
enters, atrium
______ are located in ___ and stop blood from flowing backwards
Valves, veins
What removes particles from the air inhaled?
Cilia
The rate of respiration is controlled by the amount of —
Carbon dioxide in the blood
When there is more Carbon dioxide in the blood, is the rate of breathing higher or lower?
Higher
What process produces the most ATP?
aerobic
What process uses sunlight to make glucose?
Photosynthesis
Carbon Dioxide (CO2) + Water (H2O) –(light energy) –> Glucose (C6H12O6) + Oxygen (O2)
Photosynthesis equation
The 3 part equation that is true for cellular respiration and photosynthesis
Inorganic+Inorganic=Organic
When your diaphragm contracts you…
inhale
When your diaphragm relaxes you…
exhale
Ribs expand, volume in the chest cavity increases
Inhale
Ribs contract, volume in the chest cavity decreases
Exhale
Why is oxygen needed by the cells
It’s needed for aerobic respiration
What two parts of respiration take place in the mitochondria?
Krebs cycle, Electron chain transport
what part of the respiratory system does gas exchange
alveoli
Alcohol and lactic acid fermentation are forms of —- respiration
anaerobic
disorder caused by cigarettes, disintegration of alveoli
emphysema
Alveoli is inflammed
pnemonia
Can alcohol fermentation be reversed?
No
Can lactic acid fermentation be reversed?
Yes
What builds up when muscles work with a lack of oxygen?
Lactic acid
