Bruco is developing a model of the human circulatory system. which sequence of blood flow should the model show?

Blood flow through the heart is very specific. The oxygenated blood gets an entry into the left atrium which then passes to the left ventricle through bicuspid valve.

The oxygenated blood goes to the tissues and organs through aorta and arteries. The deoxygenated blood from the tissues gains access in the right atrium or auricle of the heart which then passes to the right ventricle through tricuspid valve.

Lungs receives the deoxygenated blood through pulmonary artery for the purification of blood. Left atrium ultimately recives the purified blood from lungs through pulmonary vein (the only vein to carry oxygenated blood).

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.
