Concept of Homeostasis - Body systems maintain homeostasis, a dynamic steady state in the internal environment - Body System Contributions to Homeostasis

9 important questions on Concept of Homeostasis - Body systems maintain homeostasis, a dynamic steady state in the internal environment - Body System Contributions to Homeostasis

How does the circulatory system contribute to homeostasis?

The circulatory system (heart, blood vessels, and blood)  transports materials such as nutrients, O2, CO2, wastes, electrolytes, and hormones from one part of the body to another where it can be used

State the 3 ways that the digestive system contribute to homeostasis?

The digestive system (mouth, esophagus, stomach, intestines, and related organs);
1. breaks down dietary food so that they are small enough nutrient molecules that can be absorbed into the plasma for distribution to the body cells.
2. It also transfers water and electrolytes from the external environment into the internal environment.
3. It eliminates undigested food residues to the external
environment in the feces.

List 2 ways that the respiratory system contribute to homeostasis?

The respiratory system (lungs and major airways);
1. Gets O2 from and eliminates CO2 to the external environment.
2. Maintains a proper pH of the internal environment by By adjusting the rate of removal of acid-forming CO2,

What substances does the unrinary system remove which contributes to homeostasis?

removes excess water, salt, acid, and other electrolytes from the plasma and eliminates them in the urine, along with waste products what are not CO2.

List 4 ways in which the skeletal system contributes to homeostasis?

provides support and  protection for the soft tissues and organs
storage reservoir for calcium (Ca2+)
together with the muscular system moves the body
site of red blood cell production

How does the muscular system contribute to homeostasis?

the heat generated by muscle contraction helps maintain body temperature.

How does the immune system contribute to homeostasis?

defends against foreign invaders like  bacteria and viruses & against body cells that have become cancerous.

It also paves the way for repairing or replacing injured or worn out cells.

How does the nervous system contribute to homeostasis and how is it unique?

Nervous system is unique becuase it is one of 2 major regulatory systems.
it controls and coordinates bodily processes that require fast responses

How does the endocrine system contribute to homeostasis and how it is unique?

Endocrine system is 1 of 2 major reglatory systems.
In contrast to the nervous system, the endocrine system in general regulates activities that require duration rather than speed
