Explain why fish die when they do not get enough oxygen​

Biology
1 answer:
Shtirlitz [24]3 years ago
6 0

Answer:

Fishes have a very particular respiratory system, which manages to extract the dissolved air from the water. They do it thanks to the gills, membranes located on the sides of their body. When the animal opens and closes its mouth, the liquid enters its interior through them and that is when the blood vessels absorb the necessary oxygen. If the water has toxic components or dirt, there will not be the necessary amount of oxygen.

Explanation:

Fishes obtain the oxygen they need from the water through the gills: membranous structures supported in turn by cartilaginous or bone structures. The gill surfaces are very wide, and respiratory gases are exchanged between blood and water as it flows over them. The fish takes water through its mouth and, through a complex process, releases the water through the lids, previously passing through the lamellae, where oxygen is captured. If the water has toxic components or dirt, there won’t be the necessary amount of oxygen, there would be impurities that limit oxygen. Pollution causes the loss of oxygen. Efficient oxygen absorption from water (as gills do) is essential for active organisms in the aquatic environment. Fishes promote gas exchange by ventilating the gill surfaces, either by actively pumping water through the gills, or by continuously swimming with their mouths open. In the end, the fish die because they cannot find what they need to live.

Assume that the body has been sectioned along three planes: (1) a median plane, (2) a frontal plane, and (3) a transverse plane
Anit [1.1K]

Answer:

lungs and kidneys

Explanation:

The median plane divides the body into two halves through a mid line.

The transverse plain is also known as the axial plane and it divided the body into the upper part and a lower part.

The frontal plane is also known as the coronal plane. It divided the body into the dorsal and ventral sections. The dorsal and ventral sections are the front and back sections ( belly and back).

Lungs and kidneys are the only parts which cannot be seen through all the three plains.

Describe the flow of blood from the umbilical vein to the descending aorta in the developing fetus.
n200080 [17]

Oxygen and nutrients from the mother's blood are transferred across the placenta to the fetus through the umbilical cord. This enriched blood flows through the umbilical vein toward the baby's liver. There it moves through a shunt called the ductus venosus. This allows some of the blood to go to the liver.

A small amount of the blood continues on to the lungs. Most of this blood is shunted through the ductus arteriosus to the descending aorta. This blood then enters the umbilical arteries and flows into the placenta. The oxygen rich blood then returns to the fetus via the third vessel in the umbilical cord (umbilical vein). The oxygen rich blood that enters the fetus passes through the fetal liver and enters the right side of the heart.
