- Explain what a partial pressure gradient is and how such gradients figure in gas exchange.arrow_forwardwhat is the contribution of enucleated erythrocytes to homeothermy?arrow_forwardPulmonary 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 decreasearrow_forward

- Blood pressure at the arterial end of capillaries is about 40 mm Hg in humans.

Describe all the factors that make them ideal for transporting oxygen to cells.arrow_forward
- If there is increased hydrostatic pressure on the venous side of the capillaries leading to an increase in fluid moving into the tissues why would it cause ankle edema? What role does the lung play in development of that increased hydrostatic pressure in terms of alveolocapillary membrane/lung changes. What is the effect on oxygen diffusion from the alveolus, on pulmonary artery pressure and resultant changes to the right side of the heart)?arrow_forwardA general principle of physiology states that information flow between cells, tissues, and organs is an essential feature of homeostasis and allows for integration of physiological processes.
