The 2 roles of calcitonin.
What is bones take up calcium ions? What is kidneys to reduce Ca uptake?
The hormone that opposes calcitonin and its role.
What is PTH? What is release Ca ions from bones? What is cause Ca reuptake in kidneys?
The pancreas’ response to hi blood sugar and the liver’s action.
What is the pancreas releases insulin & the liver takes up glucose & stores it as glycogen?
Vitamin D’s role in regulating Calcium ion concentrations.
What vitamin D is converted to a steroid like molecule that stimulates the intestines to take up more Ca ions? (it reinforces the effect of PTH)

What is glomerulus?
______ is removed from the filtrate in the descending loop and ____ is removed in the ascending.

What is inner medulla, outer medulla and cortex?
This role of ADH in regulating kidney.
What is when you’ve had plenty of water, less ADH is released and the urine gets very dilute? What is when you’ve had very little water, more ADH is released, more water is taken up by collecting duct and urine gets very concentrated?

In biology, there are lots of repeating units that function in many parts of the body. This is the repeating unit found in the muscle fibers.
What is the sarcomere?
The boundary of the muscle fiber.
What is the Z line?
This area only has actin(thin) fibers when the muscle is at rest.
What is the i-band?
All 3 of these zones get shorter when the muscle contracts.
What are H, I and Z?
DESCRIBE how muscles are kept from contracting when the body is not using them with the 3 key players.
What is Calcium must be present, tropomyosin blocks actin’s active site and myosin (thick) can’t bind?

What is left (O) and right (DO)?
The heartiest chamber of the heart & why.
What is left ventricle because it has to pump blood throughout the body/to the extremities?
The heartbeat is regulated this way by this part of the heart.
What is the SA node sends out impulses that sets the rate and timing of the contractions?
