The liver in fish produces bile which is stored in the gall bladder until a bolus passes the stomach, at which time the bile is expelled into the intestine. In small amounts, bile can be passed out of the fish in small amounts through the gills. Bile production is regulated by a number of hormones which are secreted by the liver. The most important of these is the hormone bicarbonate (HCO 3 -).
This hormone is produced in response to the acidity and alkalinity of blood. pH is too high, the body produces acid, and when it’s too low, it produces alkaline. In the presence of too much acid or too little alkali, blood pH drops, causing a condition known as hyperkalemia. This condition can lead to a variety of health problems, including heart disease, high blood pressure, kidney failure and even death.
It is important to note, however, that this is only one of many factors that can affect a fish’s biliary function. Other factors include the type of food eaten, how much fish is eaten and how long it has been on the menu, as well as environmental factors such as temperature and salinity.

Where is the liver in a fish?
The liver of fishes is a dense organ ventrally located in the cranial region of the general cavity. It’s size, shape, and volume are adjusted to the space between the vertebral column and the liver. The liver is divided into two lobes, the left lobe being larger than the right lobe. Liver is the largest and most important organ of fish.
It contains a large amount of fat, which is necessary for the body to function properly. In addition, it contains enzymes that help to break down fats and carbohydrates, as well as vitamins and minerals.

- (2) stomach
- (3) intestine
- (4) heart
- (6) kidney
- (7) testicle
- (8) ureter
- (11) rectum
(5) swim bladder
(9) efferent duct (10) urinary tract
It is also the most metabolically active organ. The liver also plays an important role in digestion and absorption of nutrients, as well as in detoxification and elimination of waste products.
In addition to the liver, other major organs of fish include the stomach and intestines, which are also important for digestion, absorption and excretion of food and water.
Do all animals have livers?
The liver is a major organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and biochemicals necessary for the body to function properly. The liver also plays an important role in the metabolism of carbohydrates, fats, proteins, vitamins and minerals.
Liver function is affected by a number of factors, including age, gender, body mass index (BMI), smoking status, alcohol consumption, physical activity level, dietary intake, diet quality and other lifestyle factors. Liver disease is the most common cause of death in people over the age of 50 years.
Do fishes have hearts?
Fish have a two-chambered heart. The blood is pumped through the gills. After going through the organs, blood returns to the heart. Gills are located in the back of the fish’s body. They are used for respiration. The fish can breathe air, but it takes a lot of energy to do so.
A fish with a gill is called a “breathing fish.” The heart of a breathing fish is also called the “heart of life” because it is the source of all life on the planet.
Do fish have feelings?
According to all the evidence, fish can feel pain, pleasure, and both fear and pleasure. This is known as the ‘paradox of consciousness’ and it has been observed in many species of fish, including sharks, rays, tuna, mackerel, herring, salmon and trout. It is thought that this is because fish have evolved to be able to detect and respond to their environment in a similar way to humans.
However, unlike humans, they do not have the ability to experience pleasure or pain in response to certain stimuli, such as food or predators. Instead, their brains are wired in such a way as to prevent them from feeling any of these emotions. In other words, in order for a fish to feel any emotion at all, it would have to have a brain that is wired differently to that of a human, which is not the case for most fish.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. According to research, fish may be less active and less alert to danger. Some fish float in place, others wedge themselves into a secure spot in the mud or coral, and some even sleep on the surface of the water.
Some fish, such as the Pacific bluefin tuna (Thunnus thynnus) and the Atlantic cod (Gadus morhua), are known to sleep during the day and wake up at night. These fish are able to do this because they have the ability to regulate their body temperature, which allows them to maintain a constant internal temperature.
When they are awake, the temperature of their bodies rises and falls with the rising and falling of water temperatures. During the night, however, their internal body temperatures drop and stay low. This allows the fish to stay awake and alert, even when the surrounding water temperature is dropping.
Do cod fish have livers?
The liver is designed to process toxins. Cod fish accumulate more toxins than smaller fish because they are long-living. Cod liver oils are also rich in omega-3 fatty acids. These are important for brain development, immune function, and brain function in general. They also have anti-oxidant properties, so they can help protect the brain from damage caused by free radicals.
In fact, a study published in the Journal of the American Medical Association (JAMA) in 2010 found that people who ate the highest amounts of fish oil in their diet had lower rates of Alzheimer’s disease than those who consumed the lowest amounts. (The study was funded by the U.S.
