What is the function of the gill filaments?

The gill filaments in fish have functions like lungs in people: it’s the organ responsible for absorbing oxygen and expelling carbon dioxide. The gills also regulate levels of mineral ions and the pH of the blood, as well as being the primary site of nitrogenous waste excretion, in the form of ammonia.

What is the function of the greater omentum?

Function of the greater omentum The greater omentum prevents the parietal and visceral peritoneum of the abdominal cavity from adhering to each other. For example, it prevents the parietal peritoneum lining the anterior abdominal wall from sticking to the visceral peritoneum of the ileum.

What does the falciform ligament do?

The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the liver into the left medial lobe and right lateral lobe.

Which structure of gill plays a role in feeding?

Gill rakers in fish are bony or cartilaginous processes that project from the branchial arch (gill arch) and are involved with suspension feeding tiny prey. They are not to be confused with the gill filaments that compose the fleshy part of the gill used for gas exchange.

What is the function of gills in the body of fish?

Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat).

What is the function of gills in mushroom?

A lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often but not always agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification.

Is the greater omentum attached to the liver?

The greater omentum is attached to the lower portion of the stomach (here the attachment is cut and the stomach is lifted up). The celiac artery and its branches; the liver has been raised, and the lesser omentum and anterior layer of the greater omentum removed.

What organ S does the greater omentum attach to?

stomach
The omentum attaches ventrally to the greater curvature of the stomach and dorsally to the greater curvature of the stomach and the pancreas and spleen.

What is falciform ligament of liver?

The falciform ligament is the thin, sickle-shaped, fibrous structure that connects the anterior part of the liver to the ventral wall of the abdomen. The falciform ligament attaches to the liver between the right and left lobes as well as attaching to the inferior diaphragmatic surface.

What is the falciform ligament a remnant of?

The falciform ligament is the remnant of the ventral part of the ventral mesentery. It contains the obliterated umbilical vein, and it is the structure in which large collateral veins are recruited in patients with advanced portal hypertension.

What is the function of gills and lungs?

Gills and lungs are the two types of respiratory systems that occur in vertebrates. Their main function is to facilitate gas exchange. They are surrounded by blood vessels. They help to take oxygen from the outside environment while eliminating carbon dioxide to the outside.

What is the role of gills in fishes?

What is the interlobular septa?

The interlobular septa (sing: septum) are located between the secondary pulmonary lobules and are continuous with both the subpleural interstitium (peripheral connective tissue) and the peribronchovascular interstitium (axial connective tissue) as well as the more delicate intralobular septa. These septa are composed…

What are the septa of the lungs composed of?

These septa are composed of connective tissues within which run the pulmonary veins and lymphatics which drain towards the pleura (NB a second set of lymphatics runs along with arteries and drains centrally).

How is the liver attached to the stomach During evisceration?

The liver is attached by ligament to the anterior abdominal wall and to the stomach by the lesser omentum. During evisceration these attachments are torn or cut, and the liver is removed attached by ligament to the diaphragm and the rest of the pluck (heart, liver, lung, and diaphragm).

What is the pathway of blood through the hepatic system?

Veins lead out of the lobules merging into larger veins eventually flowing into the hepatic veins; blood then leaves the liver through the inferior vena cava, the largest vein in the body. Ducts transport bile out of the lobule flowing into larger right and left hepatic ducts.
