If a lung having a normal ventilation-perfusion ratio (=1) SUDDENLY develops ventilation-perfusion ratio <1, which of the following will occur? Explain
A decrease in arterial pO2
An increase in alveolar pO2
A decrease in cardiac output
A decrease in arterial pCO2

In: Anatomy and Physiology
Which of the following is true about ventilation-perfusion coupling?
in alveoli where ventilation is inadequate, the partial pressure of oxygen is high
terminal arterioles dilate in areas where the partial pressure of oxygen is low
blood is shifted towards alveoli with low partial pressure of oxygen to enhance oxygen pick-up from lungs
in alveoli where ventilation is maximal, the partial pressure of oxygen is low
terminal arterioles dilate in areas where the partial pressure of oxygen is high

EACH STATEMENT IS A T/F QUESTION PLEASE ANSWER ALL 12
Pulmonary function limits physical performance because transit time through the pulmonary capillaries is reduced to 0.4 seconds during maximal exercise which is not enough time for complete oxygenation of the blood.
Oxygen binds to the globin portion of the hemoglobin molecule.
HCO3- diffuses out to plasma at tissue level and chloride (Cl-) into the RBC, known as chloride shift.
Carbonic anhydrase is present in the RBC and catalyzes the formation of lactate.
During exercise, tidal volume does not change relative to tidal volume at rest
Alveoli are the lung structure where gas exchange takes place.
Partial pressure of a specific gas affects the driving force behind that gas.
The immediate and largest increase in ventilation during exercise is due to changes to chemistry of arterial blood.
An increase in pH is in part responsible for the Bohr effect.
Inhalation is an active process, it involves contraction of the diaphragm.
Cooperative binding refers to the ease at which O2 binds to Hb with each subsequent O2.
HCO3- (bicarbonate) accounts for the majority of CO2 transport.

After having read the chapter on Health and Medicine, think about the 'complementary/alternative' approaches to medicine mentioned in the text. Answer the following questions:
1. Do you think that we will see a wider acceptance of these methods in mainstream 'medicine' in the near future? (Whatever your answer, focus on one of the types of alternative medicine and explain WHY you think we will or will not see it more widely accepted)
2. What do you think contributes to the 'slowness of acceptance' of these methods in mainstream North American culture? Identify and explain please.

Explain why maximal wrist extension is not passive insufficiency of the muscles generating grip force. Since this is not an example of passive insufficiency, explain why maximal wrist extension is generally not the ideal wrist position for generating maximum grip force.

1. Identify the four major types of muscle contraction. Provide an example of each type in which you experience in your daily life. When exercising, do you find yourself doing more static or dynamic types of muscle contraction?
2. Discuss the differences between muscular strength (absolute and relative), power, and endurance. In your own experience, what types of activities, exercises, and/or sports require muscular strength, power, and endurance? Which is most important for you in your daily life?
3. Which of the factors that influence muscular contraction do you feel are the largest influencers in your opinion? Why?

The term "Phenotype" refers to:
The combination of alleles that an organism has for a given gene.
Another word for a musical device that plays vinyl records.
An odor or scent that affects how organisms behave toward one another.
The trait that is expressed as a result of a combination of alleles.

How does heat exchange occur across the walls of capillaries? Specifically, how are certain veins/arteries/capillaries cooler or warmer than other ones? How does the body regulate that to make certain parts hotter or cooler?
