Answer:
a The pulmonary artery carries deoxygenated blood.
Explanation:
This is the the only artery that transports deoxygented blood in mammals. specifically it carry deoxgenated blood from the the atria to the pulmonary circulation. That is to the lungs for the exchange of the C02 in the deoxygenated blood with oxygen in the lungs.
The blood thus become oxygenated,and therefore return through the pulmonary veins to the left ventricle.
From the left ventricle ,through ventricular systole,blood is empty into the aorta through the aortic valves into the systemic circulation.
Although,they carry blood away from the heart,but the blood is de oxygenated instead of the usual oxygenated by arteries,They are still regarded as arteries because of convey of blood away from the heart,a typical role of arteries

<span>The ocean affects the earth’s climate by utilizing the sun’s

the warm climate to the state. Also, the ocean’s play a major role in the water
cycle. The amount of precipitation falling on an area can affect its weather
and climate. hope this helps!!!! </span>
The defecation reflex involves two postive feedback loops. these loops are the stretch receptors in the rectal walls and the sacral parasympathetic system. Defecation reflex empties the rectum by peristaltic movements push fecal matter from the sigmoid colon into the rectum. Then this distension of the rectal walls stimulates stretch receptors which results in defecation.
