Gas Exchange Lab Report

The blood is pumped by the heart through the afferent bronchial arteries to capillaries in the gills, where the blood is oxygenated). The blood

The operculum is a late that forms a flap that covers the gills in bony fish. Since it did not have an operculum, the fish most likely moved water or air through respiratory organs by the mouth either pumping or changing shape. In other words, it is possible that Tiktaalik was capable of breathing through its mouth.Thus, Tiktaalik did not solely rely on gills for breathing.

Secondly, the human body, crayfish, earthworm, and frog also have many similarities and differenced of how their respiratory system works. The crayfish respiratory system is the least complex. Crayfish have gills, which are used to release carbon dioxide and to pick up oxygen, by having a constant flow of blood. Frogs consist of nostrils and larynx, which opens up two lungs. The walls of the lungs are filled with capillaries. Capillaries are

All the animals I will be discussing have an anus and mouth because they all contain a complete digestive system. A closed circulatory system is a system that has blood closed within the vessels and does not fill the body cavities. The open circulatory system describes a system where blood and interstitial fluid can mix in with an organism. Interstitial fluid is just the fluid found between cells in the body (Study.com). The perch, chordate and fetal all contain a closed circulatory system, but the starfish differs it has an open circulatory

This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration, also known as aerobic metabolism, occurs when oxygen is taken into the body and sent to all its cells; the oxygen is then used to break down food for energy (White and Campo 2008). Respiration can be experienced through several structures such as the lungs, tracheae, gills, and integument in order to obtain

The test subjects, O. rusticus crayfish, were collected from the White River.. Body length and body weight were measured with the use of a measuring tape and a gram scale. The rate of oxygen consumption was studied by the use of intermittent closed respirometry with a Q-box AQUA device. This was conducted by measuring the amount of dissolved oxygen present in the water chamber without removing the organism from the container so as to demonstrate the amount of oxygen consumed by the crayfish over a given set of time. By periodically measuring the amount of oxygen present in the water at an interval of twice per second, the rate of oxygen consumption can be

Imagine you are at the bottom of the ocean, and there are hydrothermal vents ejecting hot lava. Adding to your misery, there are huge amounts of hydrogen sulfide gas everywhere that are poisonous to your body. In reality, this is the giant tube worm’s ecosystem. Ecosystems are all of the living things (plants/animals) and the non-living things that live in a specific area and interact with each other. Ecosystems can be of any size. In an ecosystem, there are biotic and abiotic components that are all linked. The pelagic zone or “open ocean zone”, where the giant tube worm, an underwater animal that lives near hydrothermal vents, lives is located next to the continental slope/drop off. The water is much deeper here. At the surface, there is

Beaked whales and deep-sea eels are evolutionarily closer as compared to cows. Cows are terrestrial animals. Therefore, the adaptation at deep sea water is different from terrestrial hence due to natural selection beaked whales, and deep-sea eels must have almost the same adaptations to survive in the deep-sea water.

A crayfish has feathery gills that are used for gas exchange. This feathery quality increases surface area to maximize the area where gas exchange takes place. Blood flows to the gills, releases carbon dioxide, and picks up oxygen. A starfish has papulae which are small, hollow, growths that act as simple gills. Respiration also occurs in the tube feet where the starfish picks up oxygen and releases carbon

Is the circulatory system of arthropods more similar to that of annelids or of mollusks? Why?

This lab deals with the transpiration rates in plants, specifically a tomato plant that was used for this experiment. Transpiration is when water leaves a plant through the stomata as water vapor while the stomata is capturing CO2 for photosynthesis. This experiment used three different scenarios: a tomato plant with a light shining on it, a tomato plant with wind blowing on it from a fan, and lastly a tomato plant with nothing acting on it. The hypothesis is that the rate of transpiration will be fastest with light, faster with wind, and slow with the control. This hypothesis was rejected because the rate of transpiration is as follows with the wind having the fastest rate: with light the rate was 7.60 mm/min, with wind 10.20 mm/min, and control 4.33 mm/min. The cause of the wind having a faster transpiration rate than the light may have been due to the surface area of the leaves on the tomato plants. The surface area of the leaves for the wind experiment is 8,124mm2, and for the light is 7,740mm2.By doing this transpiration experiment it helps one to see what happens in plants daily and understand why it happens.

Some plants and animals have to adapt to the amount of oxygen and visibility underwater. For example, plants have adapted to the amount of sunlight they receive in certain environments, and cattails and water lilies have adapted to be able to survive humid climates. For animals, certain fish like trout have adapted to clear and cool water with a large amount of oxygen. On the other hand, other types of fish, like catfish, are able to survive in an area with a low oxygen level and gloomy visibility. Since otters live on the land surrounding the water, they have adapted to be able to swim to catch their food. Frogs and alligators have adapted to their environment by being able to live on the land after coming from underwater as an egg. Lastly, beavers have adapted to use their teeth to create the dams they live

The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange, this is necessary to sustain life. During the process of breathing air is inhaled and carbon dioxide is exhaled, this change of gases occurs in the alveoli. The inhaled oxygen passes into the alveoli and then diffuses into arterial blood. The waste rich blood from the veins releases carbon dioxide into the alveoli which is

Within the alveoli, the oxygen is transferred to the blood whilst simultaneously collecting waste carbon dioxide for excretion as we breath out. This transference is known as diffusion and is linked to the cardiovascular system.

Gas Exchange is a physical process. During that physical process diffusion is involved which are two main gases oxygen (O2) which is needed for respiration, Carbon dioxide (CO2) that is produced in respiration.
