give a detailed explanation to how the bicep muscles are able to contract IN ORDER AT the CELULAR and MYO FIBER levels when you go and sip a glass of coffee. these following ideas must be incorporated

• the fact that the resting-membrane potential is (-) charged in cells
• Depolarization as well as repolarization of the cells
• How the motor neuron's neural signal are sending to skeletal muscular cells
• adds the roles of SR andd T-tubule as well as thin and thicker filaments, cross-bridge, Calcium ions, power-stroke, muscle contraction's ATP

Pulmonary ventilation consits of what two phases? define each adn then pick one and gave the sequence of events for that phase

Describe the path a red blood cell takes traveling through the body. Begin your RBC in the right atrium and show its path until it returns to the right atrium. There should be at least 7 steps, but could be more depending on how detailed you get.

2)

Which of the choices below occurs if implantation is successful

3)

A normal expiration during quiet breathing:

Select one:

a. is an active process involving muscle contraction.

b. occurs when the diaphragm and external intercostal muscles relax.

c. is not affected by the elastic properties of the lungs.

d. requires more muscle contractions than inspiration.

e. occurs due to the contraction of the diaphragm and elevation of the ribs.

After hyperventilating for several minutes:

Select one:

a. blood pH would drop and inhibit inspiration.

b. blood pH will rise and stimulate expiration.

c. O₂ in the lungs has not had time to diffuse into the blood.

d. the level of O₂ has increased and inhibits the inspiratory center.

e. the level of CO₂ decreases below the level necessary to stimulate the inspiratory center.

Understand the basic organization of the respiratory system and how that structure leads to it’s function, both in terms of the mechanics of breathing (getting the air to the alveoli) and in terms of gas exchange at the alveolar- pulmonary capillary interface.

Given that cardiac output (CO) is determined by two variables, heart rate (HR) and stroke volume (SV), compare a size-paired aerobically trained individual’s cardiac output (and associated HR and SV) with that of an untrained individual at various paired workloads: rest, moderate intensity exercise and COmax. (Vo2max)

In cells especially those in the liver, glucose molecules are bonded together to form glycogen. Why?

c. flexor digitorum profundus

d. extensor digitorum

e. All of the above except A
