What is the difference between the ligamentum arteriosum and the ductus arteriosus?

Biology
1 answer:
Goshia [24]3 years ago
6 0
In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.

Which qualities describe the entire open-ocean zone? Check all that apply. few nutrients
uysha [10]

<u>Answer:</u>

- few nutrients

- high pressure

- low temperatures

<u>Explanation:</u>

1. Few nutrients:  open-ocean zone is located way far from the land, which is the main source of the essential nutrients.

2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.

3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.

4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.

5. Low temperatures:  the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.

Can someone please help me
Usimov [2.4K]

Answer:

1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers

1B - Skeletal = bones

1C - Muscular = muscles

1D - Digestive = stomach, large/small intestine

1E - Circulatory = heart, veins and arteries

2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive

3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.
