holding structures deflate, the surfactant prevents the structures from sticking together. Since Serpentes have an air sack that gets completely collapsed when swallowing prey, the surfactant needs to be more fluid than what is commonly found in vertebrates to prevent the air sack from gluing itself together permanently. The surfactant would need to reduce the surface tension be below that of water. Therefore the surfactant for the air sack would require less of the disaturated phospholipids and…

Today is the best day! I went inside a giant’s respiratory system and it was awesome. I entered the respiratory system from the nasal cavity. The nasal cavity is part of the respiratory system. The nose is the primary opening for the respiratory system. Have you ever wondered how it works? The term "nasal cavity" can refer to each of the two sides of the nose or to the two sides combined. The two nasal cavities condition the air to be received by the other areas of the respiratory tract. Owing…

levels of oxygen consumption and exercise in birds—namely flapping flight—creates the highest oxygen demand of any vertebrate. The structure of the avian respiratory system is very different from the mammalian lung and some of these differences support more efficient gas exchange, whereas others may be alternative evolutionary solutions to common problems in air breathing vertebrates. Generally, the respiratory system acts as a servant to the rest of the organism by delivering enough oxygen and…

Discussion: 1. Compare the ratio of the lengths of the intestine in earthworms, frogs, pigs, and humans. What significance do the lengths have with respect to the organism? Based on dissection, it was noted that the length of the intestine in earthworms, frogs, and humans all vary in sizes. The intestine of the earthworm is about two-thirds of the worm 's body length. The length of the small intestine of the frog is 3 feet while its large intestine is about 1 feet. A pig 's small intestine…

warm-blooded animals so they are able to live in almost any climate in the world. They are a vertebrate, which means they have a backbone or spine. Most live on land and they typically give birth to live young. Description of gas exchange: In mammals gas exchange takes place in the lungs. Mammals inhale oxygen though their mouth as part of ventilation and exhales carbon dioxide. The air travels down the trachea before it branches off into the two bronchi. Branching off the bronchi are the…

The external features of a lion help them survive in their habitat. Both females and males have a golden tan color that help them camouflage to their surroundings. However, there does exist a white variant which appears once in awhile in some lions. There is a huge external difference that separates males and females which is the male's mane. The mane is large and bushy, and it stretches all the way from the neck to the beginning of its back. It also gets darker as the lion ages. The lion has…

begins the breakdown of carbohydrates. Pharynx: • Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth. Branching off the pharynx is the oesophagus, which carries food to the stomach, and the trachea or windpipe, which carries air to the…

The subphylum Vertebrata includes all the familiar animals we tend to see everyday, and some rare and unusual ones (O’Neil, 2012). Scientists classify the seven different Vertebrates based on their skeletal system, general environmental adaptation, and reproductive systems. These seven Vertebrates include, Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. During the lab dissection, the class dissected organism from only four of these classes. First, we dissected the…

lungs which carry gasses as we breathe. These all connect to help us breathe and help us stay alive. The nasal cavity is a large air space which is filled above the nose. Each nasal cavity is a part of one of the two nostrils. The trachea is a tube and air-breathing vertebrates from the larynx to the bronchi, acting as the passage conveying air to the lungs. The Larynx is a hollow muscular organ making an air passage to the lungs holding the vocal cords in humans. The bronchi is a large air…
