section 2: biological system functions

1. which systems interact to maintain blood calcium homeostasis?

a. respiratory, digestive, muscular, skeletal
b. endocrine, digestive, urinary, skeletal
c. respiratory, lymphatic, reproductive, endocrine
d. endocrine, urinary, integumentary, muscular

1. how does the digestive system help defend against illness?

a. producing antibodies
b. maintaining low stomach ph to kill pathogens
c. regulating body temperature
d. producing white blood cells

Explanation:

1. During physical activity, the respiratory system takes in oxygen and the circulatory system transports it to the body's cells.
2. The cardiovascular system (a part of the circulatory system) distributes nutrients absorbed by the digestive system throughout the body.
3. During puberty, the endocrine system releases hormones that trigger the changes in the reproductive system and other body - wide changes.
4. The endocrine system regulates calcium levels, the digestive system absorbs calcium, the urinary system excretes calcium, and the skeletal system stores and releases calcium to maintain blood calcium homeostasis.
5. The digestive system helps defend against illness by maintaining a low stomach pH which can kill many pathogens that enter the body through food and drink.

Answer:

1. B. Respiratory and Circulatory
2. B. Cardiovascular system
3. B. Endocrine system releases hormones triggering changes
4. B. Endocrine, Digestive, Urinary, Skeletal
5. B. Maintaining low stomach pH to kill pathogens
