Q

Atp had been described as the body’s energy currency. How would our body retrieve energy from atp during normal metabolism?

A

The bonds between the phosphate groups store energy. Energy can be released during metabolism by breaking high energy bonds

Q

Step by step muscle contraction process

A

1.Acetylcholine is released onto the muscle cell
2.Acetylcholine causes Na channels to open in muscle cell which results in the
generation of action potential in muscle membrane
3.Action potential travels down t-tubule
4. Arrives at the sarcoplasmic reticulum, opens calcium channel
5.Calcium is put into cytoplasm where it binds to troponin
6.Troponin and tropomyosin uncoil from actin filament to expose the myosin head
7.ATP binds to myosin head allowing for myosin head to bind to myosin head binding
site
8. ATP converts into ADP+pi through hydrolysis, which allows for the myosin head to
swivel

20
Q

What is co2 converted into when it is leaving the cells and free floating in the bloodstream?

A

carbonic acid

21
Q

Function & structure of #5

A

Axon- receives signals

22
Q

Where dos co2 move to at the systemic circuit?

A

alveoli

23
Q

What component of a myocyte covers the myosin binding site on the actin filaments?

A

tropomyosin

24
Q

What main function takes place at a capillary bed?

A

gas exchange

25
Q

Where does erythropoiesis take place in the human body? what is the function? how does the kidney play a role?

A

It takes place in the bone marrow. The function is to make more red blood cells. The
kidney detects the amount of oxygen in the blood. If there’s not enough it will release
erythropoietin, stimulating the process of erythropoiesis.

26
Q

Identify brain area #5

A

Axon- transmit signals

27
Q

Where is water moving in a hypertonic solution? How is this related to the blood vessels?

A

water moves out. so the blood vessels will constrict

28
Q

Pacer cell purpose?

A

The purpose of pacer cells is to send out an electrical stimuli to allow for the contraction
of the ventricles

29
Q

What artery in the body contains high levels of co2?

A

pulmonary artery

30
Q

What is not an example of the 1st line of defense in innate immunity?

A
31
Q

Differences between humoral immunity and cell-medicated immunity?

A
32
Q

6 structure

A
33
Q

Function of osteogenesis. what is necessary for the proccess?

A
34
Q

t/f the pulmonary vein is highly saturated with co2

A

true

35
Q

What is the P in the ekg reading?

A

depolarization

36
Q

What takes place at the loop of henle? how does it impact the collecting duct?

A
37
Q

t/f macophages are not a phagocytic cell?

A
38
Q

Hypertonic solution?

A

too much water is going in causing bv to get too filled

39
Q

where does gas exchange happen in the respiratory system?

A

Alveoli

40
Q

what type of cut?

A

Sagittal cut

41
Q

what isn’t being put back in the bloodstream during filtration?

A
42
Q

how does a wbc determine if it’s self of foreign?

A
43
Q

structure of #1 and function

A
44
Q

how does innate immunity set adaptive immunity into motion?

A
45
Q

sequence of urine flow leaving the body?

A

Kidney-pelvis-ureter-bladder-urethra
