In the heart, the mixing of oxygen-rich and oxygen-poor blood is prevented by the . • septum. .
• pericardium. .

Answers

Answer 1
Answer:

In the heart, the mixing of oxygen-rich and oxygen-poor blood is prevented by the muscular wall known as Septum.

What is the function of the heart?

The function of the heart is understood by the fact that it efficiently pumps blood throughout the body. This pumping of blood to the entire body delivers the supply of oxygen, hormones, and various other nutrients to each and every cell of the body for its metabolic processes.

The right and left sides of the heart are separated by a muscular wall which is known as a septum. It prevents blood without oxygen from mixing with the blood that has oxygen. The heart also has valves that separate the chambers and connect to major blood vessels.

Therefore, in the heart, the mixing of oxygen-rich and oxygen-poor blood is prevented by the muscular wall known as Septum.

Can goldfish live in the ocean?

Answers

Answer:

Explanation:

No as they are freshwater fish and the ocean is saltwater.

Final answer:

Because goldfish are a freshwater species, they would not be able to survive in the ocean. The high salt content of seawater would negatively affect their bodily functions, leading to dehydration and salt imbalance.

Explanation:

Goldfish, a freshwater species, would face significant challenges in an ocean environment due to the high osmolarity—high salt concentration—of seawater. Goldfish have gills adapted for freshwater, meaning the osmolarity in their bodies is higher than their surroundings. Therefore, water naturally diffuses into their bodies to balance out the ionic concentration and they filter out excess water through their gills.

However, if a goldfish were to live in the ocean, the surrounding osmolarity would be higher than its body's. The high osmolarity of seawater would cause water to constantly diffuse out of the fish’s body, leading to dehydration. Simultaneously, additional salts from the seawater would accumulate in the fish's body, causing a salt imbalance that would be detrimental to the goldfish's health.
