Hi sorry for the interruption in the question marathon, but can somebody explain which out of the two, fetal hemoglobin or myoglobin, have a higher affinity for oxygen and why?

all correct, but 2 would be 100ml/hour Your turn!

1. 15
2. Interstitial fluid becomes lymph by going into lymphatic capillaries, then through the afferent vessel into the lymph node, exiting through the efferent vessel. It then goes into a lymphatic trunk, draining into a lymphatic duct (either right lymphatic or thoracic), then into the subclavian veins, and returns to the blood where it becomes interstitial fluid again. 
3. It carries part of the AV bundle (right branch of bundle of His) to the anterior papillary muscle 
4.not sure what you mean by regions of the collecting duct, but it goes through the cortex and medulla?
5. External trauma ?

[Mr.Epithelium]

Going to start a new question set!

a) Which type has microvilli on the surface?
b) Which cell is responsible for responding to aldosterone?

2. Which plasma protein mainly contributes to the osmolarity in blood?
3. The right lymphatic duct drains at the junction of what 2 veins?
4. Which chamber of the heart is the foramen ovale found?
5. Do amino acids pass through the filtration membrane in the nephron?

6. Name all the following that are retroperitoneal: Kidneys, Ureters, Urinary bladder, Urethra
7. Explain the baroreceptor reflex in the cardiovascular system.
