Homeostasis: Maintaining the Internal Environment Explained
Test: Homeostasis
20 questions
Question 1: The skin is not considered the primary organ responsible for heat exchange within the body's homeostatic mechanisms.
A. Ano
B. Ne
Explanation: The study materials state that the 'Skin – the main organ for correct of heat exchange'.
Question 2: Cells in any living organism function properly only in the correct conditions.
A. Ano
B. Ne
Explanation: The study materials state: "The cells in any living organism will only function properly in the correct conditions."
Question 3: Is the maintenance of a constant internal environment referred to as homeostasis?
A. Ano
B. Ne
Explanation: Homeostasis is defined as the maintenance of a constant internal environment, which ensures that conditions in the blood and tissue fluid remain at an optimum for cell function.
Question 4: Blood cells are surrounded by tissue fluid.
A. Ano
B. Ne
Explanation: The study materials state that "The blood cells lie in the blood plasma, and other cells are surrounded by tissue fluid." This indicates that blood cells are found in blood plasma, not tissue fluid.
Question 5: The study materials indicate that the heart directly regulates the optimum glucose concentration within the tissue fluid.
A. Ano
B. Ne
Explanation: The study materials state that the heart 'supplies the constant pressure needed to deliver blood to the tissue, and to form the tissue fluid.' It does not mention the heart regulating glucose concentration. The text indicates that tissue fluid has 'an optimum glucose concentration for respiration' and 'Blood is now at a constant, ideal state, e.g. glucose concentration of 1mg per cm3.', but does not attribute glucose regulation to the heart.
