Question 7 The finding of any amount of anatomical dead space in the lungs indicates an obstructive lung diseace True Faise Question 8 The fatty tissue surrounding the kidneys is important because it o produces vitamin o is necessary as a barrier between the adrenal glands and kidneys o stabilizes the position of the kidneys by holding them in their normal postion o ensures adequate energy for the adrenal glands to operate efficienty Question 9 1 pts As carbon dioxide enters systemic blood, it causes more oxygen to dissociate from hemoglobin (the Haldane effect), which in turn alows more COz to combine with hemoglobin and more bicarbonate ion to be generated (the Bohr efect) True False Question 10 1 pts Which of the tollowing is not a stinulus for breathing? o arterial pH resulting from COz retention arterial Po2 below 60 rm Hg o rising blood pressure orising carbon disxide levels

Explanation / Answer

q7. False [ Anatomical dead space is the amount of air that remains in the nose to the terminal bronchiole, this air does not take part in the gaseous exchange, because this gas does not enter into the alveoli for gaseous exchange. So normal lung do have anatomical dead space, normal amount of dead space (150ml) is indicative of normal lung]

q8. Stabilizes the position of the kidney..... [ this fatty tissue surrounding the kidney is known as adipose capsule]

q9. False [ Haldane effect: oxygenation of hemoglobin dissociates carbon dioxide from hemoglobin, Bohr effect: Hb's oxygen binding intensity is inversely related with the blood pH and carbon dioxide concentration ]

q10. Rising blood pressure [ rising blood pressure does not stimulate respiratory center]
