Homeostasis

Which of the following is Physical factor

• blood sugar

• body temperature

• pH of blood

• partial pressure of carbon dioxide

Which of the following is chemical factor?

• blood osmotic pressure

• body temperature

• blood pressure

• reflex action

The Homeostasis originates from

• Latin

• Greek

• Arabic

• France

Homeostasis involve the following except:

• stimulus

• receptors

• negative feedback

• positive feedback

The system that involved in maintaining body temperature is as following except:

• nervous system

• endocrine system

• blood circulatory system

• muscular system

High sugar level can cause

• anemia

• kidney failure

• hypoglycaemia

• diabetes insipidus

During a hot day, the receptor will

• smooth muscle in arteriole vasoconstriction

• erector muscle relax

• erector muscle contract

• adrenal glands are stimulated

During a cold day

• vasodilation occur

• more heat is released from the surface of skin

• hair lowered to the skin

• skeletal muscle contract and relax more

What are the corrective mechanism when the blood sugar increases?

• more glucagon is secreted

• glucagon is transported to the liver and muscle

• insulin is transported to the liver and muscle

• glucagon stimulate amino acids to glucose

when the blood sugar drop

• alpha cell secrete insulin

• alpha cell secrete glucagon

• beta cell secrete insulin

• beta cell secrete glucagon
