Biopsychology Question:

emma Norton, 26 is admitted to hospital with acute exacerbation of her COPD

Using the knowledge of the respiratory system and the cardiovascular system, please answer the following questions below. Be sure to clearly label the different part

Part A

Emma undergoes a pulmonary lung function test. How would her total lung capacity test and her fev1/fvc values compare to normal physiological values

Part B

In hospital Emma is place on oxygen but develops respiratory depression. Explain why Emma stops breathing when she is administered oxygen

Part C

Emma’s COPD has caused pulmonary hypertension and subsequent failure of the right ventricle. What are the roles of the venous pressure and capillary hydrostatic pressure causing edema

Part D

Emma right ventricular failure has cause decrease in cardiac output. Explain which hormonal system will be activated and how it compensates for this

c)fibrinogen

d)beta globulins

e)alpha globulins

3) Fibrinogen is to fibrin as

c)All of these choices

d)ribonucleotides are to RNA

4)Sympathetic neurons could
a)speed up the heart beat

b)slow down the heart beat

d)would have no effect on the heart beat

1. Hypotension will lower the plasma osmolarity, blood pressure, and blood volume. This will activate the renin-angiotensin-aldosterone system. Overhydration will increase the blood volume. This will trigger the cardiac atrial cells to secrete atrial natriuretic peptide (ANP). Fasting will increase the plasma osmolarity, decrease blood pressure and blood volume. This will trigger the secretion of anti-diuretic hormone (ADH).

a. True

b. False

2. What is TRUE about acetylcholine? There may be more than one answer.

a. Acetylcholine is a neurotransmitter that binds to the nicotinic receptor at the motor-end-plate of a muscle fiber and it is a neuromodulator when it binds to the nicotinic receptor at the dendrites of a post-ganglionic neuron.

b. It takes two acetylcholine to open the gate of a nicotinic receptor, which will cause a greater influx of Na⁺ compared to the amount of efflux of K⁺.

c. Acetylcholine binds at the muscarinic receptors at the atria only of the heart to decrease the heart rate.

d. Acetylcholine is a neurocrine but it is never found in the blood because it is not a neurohormone.

e. Acetylcholine causes an excitatory response on the muscle fiber when it binds to the acetylcholine esterase.

3.

What force favors the glomerular filtration process?

a. Hydrostatic pressure in the glomerular capillary

b. Osmotic pressure in the glomerular capillary

c. Hydrostatic pressure in the Bowman's capsule

d. Osmotic pressure in the Bowman's capsule

e. Hydrostatic pressure and osmotic pressure in the glomerular capillary

1. Which of the following statements about the adrenergic receptors is TRUE? Select one:

a. Alpha 1, alpha 2, and beta 1 receptors have greater affinity (or sensitivity) to norepinephrine than epinephrine.

b. Beta 2 receptor has an equal affinity for norepinephrine and epinephrine while beta 3 receptor has a greater affinity for epinephrine than norepinephrine.

c. Beta 1, beta 2, and beta 3 receptors increase cAMP but only beta 1 receptor causes an excitatory response in the heart muscle.

d. Alpha 1receptor activates cAMP and causes an excitatory response to most of the sympathetic target tissues.

3. What are the characteristics of the tubular reabsorption? There may be more than one answer.

a. The proximal convoluted tubule is the initial site of tubular reabsorption, where 100% of the filtrate is reabsorbed and the process is unregulated.

b. Atrial natriuretic peptide targets the principal cells of the distal convoluted tubule and collecting duct to increase the tubular reabsorption of water.

c. The descending limb of the loop of Henle only causes the reabsorption of water back into the blood of the peritubular
capillary.

d. The ascending limb of the loop of Henle causes the reabsorption of Na⁺, K^+, Cl^-, Mg²⁺, and Ca²⁺ but not the reabsorption of water due to high level of cholesterol within the membrane.

e. More than 80% of the tubular reabsorption is regulated at the distal convoluted tubule and collecting duct in the presence of aldosterone, anti-diuretic hormone, and atrial natriuretic peptide.
