Circulatory System of Fish - proper way of hand wash dishes in a restaurant

The fish has a simple circulation system, which consists of two-
Chamber of the heart, blood and blood vessels.
Unlike humans, they have only one cycle pattern.
Crocodile Icefish in the Antarctic does not produce red blood cells.
It is the plasma that absorbs and distributes oxygen dissolved in water.
They have a larger heart, large blood vessels and increased heart output compared to other fish. Fish are cold-
Flesh-and-blood aquatic spine found in both salt water and fresh water.
Like humans, they have a closed circulation system in which blood is always contained in the loop of blood vessels.
In other words, the blood will never leave the blood vessels or fill the cavity of the body.
A closed loop system can have one or two loop modes.
The fish has a single circulation pattern in which the blood passes through the heart only once during each complete cycle. Oxygen-
The deprived blood enters the heart from the body tissue and is pumped from the heart to the fish leaves.
The gas exchange occurs within the fish gills, and the oxygen-filled blood flowing from the fish gills is circulating throughout the body.
On the other hand, in mammals, oxygen-free blood enters the heart and is pumped into the lungs from the heart for oxygen filling.
The oxygen-filled blood returns from the lungs to the heart and is transported throughout the body.
The circulation system of fish is simple.
It consists of the heart, blood and blood vessels.
The heart of the fish is a simple muscle structure located behind the fins (and below ).
It is surrounded by the heart envelope or the heart.
The heart consists of the atrium, the ventricle, and the thin heart.
The wall structure known as the sinus vein, and a tube called the bulbus artery.
Although it has four parts, the heart of the fish is considered to be twochambered.
Unlike humans, the four parts of the fish's heart do not form an organ.
Usually they are found one by one.
Blood contains plasma (liquid part) and blood cells.
Red blood cells or red blood cells contain hemoglobin, a protein that carries oxygen throughout the body.
White blood cells are an indispensable part of the immune system.
The function of platelets is equivalent to the role of platelets in the human body, I . E. e.
They help with coagulation.
Blood vessels carry blood to the whole body.
When an artery transports oxygen-filled blood from the cheeks to other parts of the body, the veins return oxygen-free blood from different parts of the body to the heart.
Fine artery
The wall artery with capillary at the end, while the small vein is a small vein connected to the capillary.
Capillaries are tiny blood vessels located within the tissue of the body and are the bond between the arteries and veins.
The cardiovascular system of the fish includes the heart, veins, arteries, blood and fine capillaries.
A blood vessel is a tiny vessel that forms a network called a vascular bed in which blood from the arteries and veins are connected.
Capillaries have thin walls that promote diffusion, a process in which oxygen and other nutrients in the blood of arteries are transferred to cells.
At the same time, carbon dioxide and waste are transferred to the capillary.
Capillaries with oxygen-free blood (containing carbon dioxide) flow into the small vein called the small vein, which flows into the larger vein.
The veins carry oxygen-free blood into the venous sinus, which is like a small collection chamber.
The sinus vein has pacemaker cells responsible for initiating contraction so that the blood enters thin-
The atrium with walls has few muscles.
The atrium produces a weak contraction that pushes blood into the chamber of the brain.
The ventricle is thick-
There are many wall-like structures of the heart muscles.
It creates enough pressure to deliver blood to the whole body.
The brain chamber transports blood to bulbus arteriosus, a small chamber with elastic components.
Although bulbus arteriosus is the name of the chamber in teleosts (rayfinned, bony fish), the structure is called the conical artery in the elastic membrane (with cartilage bones and placenta scales)
There are many valves and muscles in the cone artery, and there are no valves in the bulbus artery.
The main function of this structure is to reduce the pulse pressure generated in the brain chamber to avoid thin-walled gills.
Fins are the main respiratory organs of fish.
They facilitate the exchange of gas. e.
Absorb oxygen from the water and eliminate carbon dioxide.
The arteries deliver oxygen-filled blood (from gills) to the whole body.
The arteries branch into microarteries, which flow into the capillaries, where arterial blood becomes venous blood because it provides oxygen and other nutrients to the cells and absorbs carbon dioxide and waste.
Venous blood is delivered to the heart, where the heart delivers blood to the lungs where carbon dioxide is replaced by oxygen.
The oxygen-filled blood is supplied to the cells in the body and the circulation continues.
Although the fish's circulation system is simple compared to humans and other mammals, it achieves an important goal by indicating the different stages of evolution of the animal circulation system. The two-
The heart of the chamber is also a research problem because it is considered in the four-
