How many molecules of insulin were given in the first hour? (0.05 IU/kg/h) Assuming 6L of blood, how many ppm is this? 1 IU of insulin is equivalent to 0.0347 mg of human insulin. Person weighs 149 lbs

1. (4pts) For the following hypothetical situations make a prediction about potential functional impact for the individual:

         Gallbladder removal

         Hyposecretion of secretin

         Vagotomy (severing of the vagus nerve) proximal to the stomach

         Lack of receptors for leptin on cells of the body

2. For each of the following digestive enzymes identify which organ or gland it is produced in/secreted by, what stimulus drives the release of that enzyme, and which macromolecules it plays a role in digesting:

3) Based on your understanding of nitrogen balance identify which condition exists in each of the following examples:

• An anorexic patient is rapidly losing skeletal muscle tissue

• A weight lifter who is increasing lean body mass

• A pregnant woman proceeding through a healthy pregnancy

• A serious burn victim who is receiving protein supplements but still losing weight

4) Jacob has been working a much longer shift than he expected and is very hungry. He is slightly hypoglycemic; luckily, he has no pathology that prevents his body from reacting appropriately. Predict what hormonal changes can be expected in Jacob in response to his low blood glucose levels, the effect that hormone will have within the body, and the specific fuel source that his cells will utilize for their metabolic needs in response to this situation.

you decided to take a break after grading all of the final exams for our course and took a much-needed vacation. Unfortunately, he went surfing and was attacked by a shark that ate his arm. you, an expert one-handed swimmer, made his way back to shore. During his swim back,

Group of answer choices

1. you sympathetic nervous system stimulated the smooth muscle around his arterioles to contract to increase his mean arterial pressure

2. you  pondered your history of making poor choices and decided is safer than surfing in shark infested waters

3. your sympathetic nervous system stimulated his heart to increase cardiac output to increase his mean arteriole pressure.

4. your circulating levels of vasopressin increased to promote the insertion of aquaporins into his collecting ducts to reabsorb as much water as possible.

5. three or four of these answers (depending on whether you lost too much blood to his brain to affect his ability to think properly).

What are the factors that influence blood clot formation, control, and dissolution?

• Describe or illustrate the intrinsic and extrinsic pathway for clot formation
• Describe or illustrate the positive and negative feedbacks
• Indicate the role of WBC in the management of clotting

Three medical doctors, each specializing in different areas, agree to set up a practice together. Suggest three (3) medical devices (one for each of the areas of specialization but not necessarily to be used exclusively in one area) that the doctors may wish to purchase.

For each device,

1. i) justify why it is necessary for, and how it can be used in, the joint practice;

2. ii) explain why it is classified as a medical device;

3. iii) state, with justification, at least two different ways of classifying the device (for

   example, diagnostic or therapeutic, and so on);

4. iv) identify the measurand and the source of the measurand.

b) Discuss three (3) factors for consideration in the procurement of these devices. Part of
the discussion must focus on whether a cross-functional team approach to the procurement process is necessary.

Note:
You will need to select the areas of specialization of the doctors before suggesting devices. Devices of Low Risk are not to be used in answering the question.

B. Medulla oblongata

In Birth Control pills:

A. progesterone inhibits oxytocin
B.. progesterone inhibits the release of LH from the pituitary gland
C. progesterone inhibits the release of FSH from the pituitary gland

Describe the path a red blood cell would take traveling through the body. Start your RBC in the right atrium and show its path until it returns to the right atrium. Should be at least 7 steps or more

Describe the physical changes that occur in the synapses of the hippocampus that may provide a physiological basis for long-term potentiation (LTP).

What is the common location where hormone receptors for Cholecystokinin, Ghrelin, Peptide YY, and Insulin are all expressed?

Please explain what effect a lack of functional androgen receptors would have on the development of the reproductive system of a chromosomally XY fetus. Assume that sry is present. The explanation should include the development of the gonads, internal reproductive system, and genitalia.

How do Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), estradiol, and androgens interact with each other to produce accelerated follicular growth in the final stage of follicular development? Please include in your explanation the synthesis of steroid hormone levels and any changes in the numbers of thecal and granulosa cells.
