Homeostasis: About the level of urine passed from a human

A human drinks 1000 CM3 of distilled water and measures the amount of urine passed at 30 minute intervals. The subject passes 175CM3 at 30 mins, 325CM3 at 60 mins, and 225 CM3 at 90 mins. Why does the subject pass more urine at 60 mins than 90 mins???

Blood types/hemagglutination assay

Hi. Can someone please help me with the following blood typing/hemagglutination assay problem. I'm confused about who is the donor and who is the acceptor. For the question, please go to the following website: Click on prior examinations; password: gauchos Go to win

Flow cytometry

Hi. Can someone please check my answers to the following multi-part question, and explain the questions I couldn't answer or that I got wrong? This is an 11-part question (!), but I think it looks worse than it is. It's 60% of a 1-hour test, so I don't think it should take more than an hour to go through, at most. For the

Arteries and Veins

Hi, What are the 2 paired arteries that serve the brain? What vein drains the pelvic organs? Thank you.

Monoclonal Antibodies and Growth Environment

Monoclonal antibodies come from clones of B cells that produce a single antibody of known specificity. B cells will nor normally divide in the absence of antibody. The special trick that allowed monoclonal antibody-producing cells to be grown in culture was: (a) Mice were immunized with antigen and T cells removed and grown

The Pink Puffer

Arnold, 67, visited his doctor for the first time in about ten years because he had noticed an increasing shortness of breath during gentle exercise. He has found this shortness of breath most noticeable whilst climbing stairs or walking up hills. Arnold had smoked one packet of cigarettes per day for about 50 years, but he re

Biology Question

Liver and the associated systems linked to digestion

What are the liver functions in the digestive system and other organ systems associated with the digestive system? How are the liver and the associated organ systems linked to the digestive system? Explain briefly.

Limit of VO2 max and muscle mass

What would be a physiologic rationale to support or refute the contention that either (1) central circulatory factors or (2) peripheral factors residing within the active muscle mass limit VO2 max?

Oxygen uptake

What maximum oxygen uptake value would you expect from a elite male cross country skier?

This job lists the various steps involved in excitation of a muscle fiber.

Carpals: Bones of the wrist

I nned to know all the wrist carpals, and a fun and easy way to remember the carpals of the human wrist. Please also inclue a picture.

Kidney regulation of osmolarity and absorption of Na and water

Why is the distal tubule/collecting duct the only place to regulate osmolarity, seeing as we can absorb Na without H20 in the ascending loop? Is it just because the effect of any change in osmolarity earlier in the tubule gets undone (by ADH) in the distal tubule? Or is it because those earlier Na transporters aren't under physi

Physiology of ascitis

It is known that in ascites, liver damage usually causes a reduced osmotic pressure, and this results in edema. How does this increase the portal venous pressure?

Advanced Physiology

For 1) - 2) Responses should be 1 or 2 paragraph clear explanations? 1) Is there a correlation between the frequency of action potentials in a single muscle fiber and the tension it can develop? 2) Describe the 4 types of chromophores in the retina? 3) For 3a - 3j answer True/False; and offer brief eplanation to suppo

Advanced: Physiology

Give 1-2 paragraph or more detailed explanation for each: 1. When an adult athlete trains strenulously at high altitudes (eg. in the Rocky Mountains for a period of months, he/she is likely to experience an increase in the concentration of oxygen carying cells in the blood, which is an example of physiological acclimatizatio

Advanced Physiology

Give detailed paragraph or more explanation to all questions: 1) A fat cell responds to the presence of the harmone epinephrine by increasing cytosolic cyclic AMP Production, which leads to the catabolism of both glycogen and fat; what is the best explanation for this phenomenon? 2) After spending several days at a high altitu

Understanding the functions of various muscles.

1. Would latissimus dorsi or teres major be the stronger extensor and adductor muscle? Explain. 2. Would adductor longus or brevis be the stronger hip adductor muscle? Explain. 3. Why are the hip abductor muscles so important during single limb stance? What are the major hip abductor muscles?
