b. The respiratory center that sets the basic breathing rhythm is located in the:

Group of answer choices

pituitary

cerebellum

hypothalamus

medulla oblongata

c. How will autoregulatory ventilation-perfusion events of the lungs help to mazimize O2 delivery to RBCs? Select all appropriate

Group of answer choices

Arterioles to poorly ventilated alveoli dilate

More blood is sent to the best ventilated alveoli

Bronchioles to poorly ventilated alveoli constrict

Bronchioles to poorly ventilated alveoli dilate

d.Where are the chemoreceptors that are monitoring blood pH and/or Partial pressure of CO2? Select all appropriate

Group of answer choices

carotid arteries

hepatic portal vein

right atrium

aorta

fourth ventricle adjacent to the medulla oblongata

Answer 1

a) Partial pressure

The pressure exerted by an individual gas in a mixture is known as its partial pressure.

b) medulla oblongata

The respiratory center is located bilaterally in the medulla and pons.
