i worked on these questions and was able to answer most of them..can you look over my answers, and help me out on the ones that im having trouble with? thanks
1. what happens to oxygen in tissues?
A: oxygen is released and taken up by hemoglobins, and the rest is kind of a blur...
2. trace oxygen back to the heart from the left hand, then to the lungs, then from the lungs out the nose.
A: i traced the oxygen in blood to the left hand before this question so im guessing the oxygen is still in the blood for this question..i know how to trace blood from the left hand to the heart (via veins to superior vena cava, and then to the right atrium), and then to the lungs (out the pulmonary artery and to the pulmonary capillaries), but im stuck on how to get the oxygen out the nose. i need help with this one.
3. you ate snickers loaded with carbohydrate, protein, and fat. Trace path of food to small intestine, and include important secretions and enzymes.
A: this is a simple trace the food down the pharynx, esophagus, stomach, and small intestine right? im not sure how i should answer the last part..important secretions and enzymes...im confused as to how i should approach this question.
4. trace absorbed fats, amino acids, and glucose back to the heart.
A: the fats, aminoa acids, and glucose are absorbed in the small intestine, right? and the glucose and amino acids enter the portal system and the fats are transported to lacteals..so first the glucose and amino acids..i would have to trace it back to the heart from the small intestine..blood is taken from the sm. intestine to the heart via superior mesenteric v., hepatic portal v., liver, hepatic v,. inferior vena cava, and then the right atrium. and then the fats..they are transported to the lacteals which are connected by the lymphatic vessels to the thoracic duct which empties into the left subclavian vein, and from the left subclavian vein, the fats in the blood would enter the superior vena cava and the heart. is this correct??
5. trace water (glucose, water) to intestines and absorb it into the blood. Trace glucose and water in blood to the kidneys.
A: i would trace water to the intestines by going through the pharynx, esophagus, stomach, sm. instestine, and large intestine. glucose and water would be absorbed into the blood by the pulmonary capillaries in the small intestine and reach the right atrium of heart via the hepatic portal vein, then from the right atrim to the pulmonary a., pulmonary capillaries, pulmonary v., aorta, descending aorta, renal a., and then the kidneys.
i hope my answers above are right..if not, ill pull my hairs out
please read over the answers and i would appreciate it if you can give me some feedbacks! TIA!
