This includes the pancreas, liver and the gall bladder. Digestion is the process of digesting food it is a process in which the food is converted or broken down into a substance that can be absorbed and assimilated by living organisms in this case it is mammals. During this process the digestive system is involved mainly the digestive

The urinary bladder is a sac-like hollow organ that is used for the storage of urine. Urine slowly fills up the bladder and stretches its elastic walls and can hold 600 to 800 milliliters of urine. The urethra is the tube that transports urine from the bladder to the exterior of the body. There are two muscles in the urethra that control the flow of the urine. They are the internal sphincter which when open results in the sensation of needing to urinate and the external urethral sphincter a skeletal muscle that will allow urine to pass through or delay urination.

The process of digestion starts in the mouth, then makes its way to the stomach and large intestine, and concludes in the small intestine. At each step along the way, specific enzymes break down specific types of food. This process is chemically balanced as each site along the digestive tract has a different degree of acidity that allows certain enzymes to function while restraining others. Each specific enzyme can bind to only one specific substrate, or group of allied chemical substances. After leaving the stomach, food pulp enters the upper portion of the small intestine where the pancreas (digestive organ that feeds enzymes into the gut) provides pancreatic enzymes to further break down the

. Genetics of Homarus americanus • 100 pairs of inverted U-shaped chromosomes, common in crustaceans. Physiology of Homarus americanus Nervous System: Homarus americanus have a primitive nervous system, one similar to those of insects. Lobsters lack a brain and only contain about 100,000 neurons, a figure a million times less than the 100 billion found in humans. Ultimately, the American lobster has a bilaterally symmetrical nervous system.

The mouth is very large with a beak-like snout (figure 2). They have jagged teeth. The maximum length caught was approximately 250 centimeters but range from 85-105 centimeters with a maximum weight of 83 kilograms (Luna, n.d.). It does not have any gill rakers. Pectoral fins (2) on each side of its body is present.

Selected Answer: two specific carbohydrates in this piece of pizza are amylopectin and amylose. When these starches enter the mouth, it stimulates the salivary glands in the mouth to secrete saliva which contains salivary amylase and begins chemical digestion of the starch. Then once chewed and swallowed, the starches make their way into the stomach where it does not undergo any further chemical digestion until it reaches the small intestine. Once the stomach is done churning the food, the pancreas secrets bile for lipid digestion..... Im sorry I cant finish this, my stomach is killing me. Correct Answer: [None] Response Feedback: the pancreas does not secrete

Cuttlefishes Introduction: Cuttlefish are small to medium sized marine animals that belong to the class Cephalopoda, which also includes squids, and octopodes. Despite their name, cuttlefish are not fish but they are molluscs. There are more than 100 species of cuttlefish which significantly vary in size from the small ones of about 15 cm in length to the Australian giant cuttlefish which can grow to up to about 50 cm in length (excluding its tentacles) and about 10 kg in weight. Based on research findings, cuttlefish have one of the largest brain-to-body size ratios of all invertebrates indicating that cuttlefish are among the most intelligent invertebrates. Distribution and habitats: The family Sepiidae, which contains all cuttlefish, is found in shallow temperate and tropical waters.

Swift, strong, stealthy, and fascinating, sharks are marvelous fish. They are well known for their incredible sharp teeth, and vicious behavior. Sharks are extremely unique and an essential part of the ocean and sea ecosystem. There are over five hundred different types of sharks living in the world. Sharks can be divided into two main groups, large and small.

* The wall of the trachea is supported by many tracheal rings.Trachea ends near the heart, where it branches into two bronchi. * The left bronchus leads to the left lung, which is very small or completely vestigial. *In most snakes, the left lung is completely vestigial. *In Boas respiratory system and pythons it is a third of the size of the right lung while in sea snakes the right lung stretches the entire length of the body to aid in buoyancy *The right bronchus leads to the right lung, which is elongated. *The anterior part of the lungs is vascular and functions in gas exchange, but the second half of the lung is nonvascular.

Anatomy and Physiology Assignment 2 – Essay The Lymphatic System The lymphatic system has three primary functions. It drains excess interstitial fluid from tissue spaces and returns it to the blood, enabling circulatory blood volume to be maintained; transports lipids and lipid-soluble vitamins A, D, E, and K absorbed through the gastrointestinal tract; and is responsible for the body’s adaptive (specific) immunity, ie. defences against microbes that breach its innate (non-specific) immunity (eg. skin, fever, inflammation): it adjusts or adapts to perform specific responses to specific microbes. In this essay, I will focus on the lymph nodes, particularly their role in adaptive immunity, and how they relate to the lymphatic system as a whole,
