Question
Chapter 34.2, Problem 1CC
Summary Introduction
To explain:
Why blood in the pulmonary veins has more oxygenated blood than venae cavae, which are also veins.
Introduction:
Heart is a muscular organ present in the left side of the breastbone. It pumps blood through the network of arteries and veins know as cardiovascular system. Human has four chambered heart in which two atria and two ventricles are present and are separated by a valve. Blood flow in human body is facilitated by double circulation. The deoxygenated blood goes into lungs via right atria and right ventricle and oxygenated blood into the body is goes via left atria and left ventricle.

Explain why blood has a higher O2 concentration in the pulmonary veins than in the venae cavae, which are also veins.
Pulmonary arterioles respond to different factors than systemic arterioles because in the lungs, the blood supply is receiving
oxygen and delivering carbon dioxide, while in the systemic circulation, it is delivering oxygen, and receiving carbon dioxide. In the
pulmonary circuit, arterioles will dilate in well-ventilated areas of the lungs to increase the rate of exchange between capillaries
and well-ventilated alveoli. However, in poorly ventilated areas of the lungs, arterioles will constrict in order to re-route blood to
well-ventilated areas. Now consider our case of pulmonary oedema, and how that will impact circulation in the pulmonary
circuit. (Select two answers).
Pulmonary arterioles will dilate
Pulmonary arterioles will constrict
O Pulmonary vascular resistance will increase
O Pulmonary vascular resistance will decrease
In pulmonary circulation, arteries carry blood from the ____________ to the ____________. Veins carry blood from the _____________ to the _______________.
