850-1200g

Question 19

99% of CA is in the

Answer 19

Skeleton

Question 20

OsteoBlasts

Answer 20

BUILD CA++ into bone

Question 21

OsteoClasts

Answer 21

CUT CA++ out of bone

Question 22

CA++ Blood levels

Answer 22

9-11 mg/ldl

Question 23

Reservoir for Calcium

Answer 23

– trabecular bone → Calcium Mobilization
Bones are a reserve source of Calcium, and the body will take from it as necessary – lack of
Ca++ in the blood will cause clotting and the heart (which uses extracellular calcium) to stop

Question 24

Controlled via hormones -

Answer 24

-parathyroid hormone (PTH)

Vitamin D and Calcitonin

Question 25

Calcium rigor

Answer 25

develops when there are HIGH blood calcium levels - this causes muscles to contract specifically in the heart and the heart may go into arrest

Answer 26

develops during LOW blood calcium levels and this can cause | uncontrolled muscle spasms

Factors that inhibit Absorption

Answer 29

``` ● Lack of stomach acid ● Vitamin D deficiency ● High Phosphorus intake ● High Fiber Diet ● Phytates in seeds, nuts and grains ● Oxalates in beet greens, rhubarb, and spinach ● High Fat Diet ● Increased GI Motility ● Caffeine and Other Drugs ```

Question 30

Parathormone (Parathyroid)

Answer 30

“stimulate” osteoclasts -- takes Calcium from Bone INTO BLOOD -stimulates the Osteoclasts by inhibiting Osteoblasts

Question 31

Answer 31

“stimulates” osteoblasts “Calcitonin in the bonin” -stimulates Osteoblasts by inhibiting Osteoclasts

Question 32

Calcium Control in Bones -

Answer 32

using HORMONES

Question 33
