1. What is digestion? a. Digestion is the intake of food and its journey through all the digestive organs, with the help of enzymes and other digestive molecules. 2. What are the three types of organic molecules (energy yielding) broken down by the digestive system? b. Proteins, sugars, and carbs.
3. What are the three types of inorganic (non-energy yielding) molecules processed by the digestive system? c. Fats.
4. For each of the three types of organic molecules explain what they are broken down into. Where they are broken down (primarily). Give a food as an example of each type of organic molecule. d. Amino Acid, Simple Sugar, Pyloric Acid 5. How does chemical digestion differ from mechanical digestion? e. Chemical is bacteria breaking down food, mechanical is chewing,
6. What is peristalsis? f. It is the involuntary constriction and relaxation of muscles. 7. Explain how activities in the large intestine help maintain homeostasis. g. They provide you with nutrients and it helps you stay healthy. 8. What is a bolus? h. A chewed food.
For Questions 9 and 10 you need to be specific and thorough. You are basically walking someone through the process of digestion with your answer. 9. What happens to food in the upper GI? Name the organs involved. i. In the upper GI the food is mushed with the teeth in the mouth and broken down by the saliva with the help of the salivary glands. Then though food is sent to the pharynx and then to the esophagus where it is sent to the stomach. 10. What happens to food in the lower GI? Name the organs involved. j. In the lower GI the stomach
2. Discuss the two divisions of the ANS. 1. Sympathetic Division – concerned with increasing alertness, metabolic rate, & muscular abilities A. prepares the body for heightened levels of somatic activity B. when fully activated, produces what is known as the “fight or flight” response C. readies the body for a crisis that may require sudden, intense physical activity D. elevates muscle tone, blood pressure, heart rate, breathing rate, and depth of respiration E…
Elizabeth was 22cm long from tail to snout, making it 115 days old, It was a female pig. The umbilical cord was still on Elizabeth, it was a tube connected to Elizabeth. The mouth of Elizabeth had sharp teeth which were hard pointy and as long as about 0.2cm in length. There was also a tongue in its mouth which was a stiff muscle. It was a very big tongue and took up most of the room in the mouth. It was 5cm by 1.5 cm. The epiglottis was a stiff but flimsy thing at the back of the mouth. It decided…
Muscle functions: 1. Movement of bones or fluids (blood) 2. Maintaining postures and body position 3. Stabilizing joints 4. Support soft tissues 5. Guards entrances and exits 6. Heat generation (skeletal muscle) Muscle Characteristics 1. Excitability (responsiveness or irritability) ability to receive and respond to stimuli 2. Contractility ability to shorten when stimulated 3. Extensibility ability to be stretched 4. Elasticity ability to recoil to resting…
ANATOMY & PHYSIOLOGY I WORKSHEET I Plasma Membrane and Cellular Transport Structure of the Plasma Membrane 1. Why do you think it is important to have a membrane surrounding each of our trillions of cells? Expect varying answers, but the idea is have the students understand the plasma membrane separates the cells from their environment and each other while also regulating the material within each cell. 2. What are two distinctive physical features of phospholipids? Heads are polar (water soluble…

The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information…
Exam questions wrong PAPER 1 22) Anti-diuretic hormone (ADH) mainly acts on the: A) renal pelvis B) efferent arteriole C) collecting duct D) ureter E) urethra 23) Micturition occurs when: A) internal urethral sphincter relaxes and the detrusor muscle relaxes B) internal urethral sphincter relaxes and the detrusor muscle contracts C) internal urethral sphincter contracts and the detrusor muscle relaxes D) internal urethral sphincter contracts and the detrusor muscle contracts E) both C and D…
animals each with their own specific anatomical and physiological features. This report will critically analyse and compare the traits of a Ring-Tailed Lemur and a Human, focusing on the Integumentary, Reproductive and Skeletal systems. These species were distinctively chosen as clear comparisons and differences can be identified. The Human surpasses the wild, terrestrial ring-tailed lemur in evolutionary form highlighting obvious anatomical differences; however these two species belong to the same…
DaVinci and Henry Gray worked the anatomy of the human body. A few of their similarities are that they both worked on the dissection of the human body. However, Leonardo DaVinci took his work a bit further and also drew what he saw when he dissected part of the human body. However, both DaVinci and Henry Gray used their dissections and included it in their writings. Leonardo DaVinci and Henry Gray both used their general knowledge to teach themselves the anatomy of the human body by dissecting corpses and…
After he graduated with his degree and became very interested in anatomy. Contributions and Achievements ● Vesalius was the one who thought it was essential to analyze the human corpse to figure out more about the human body, but it was illegal by the Catholic Church to dissect or in today’s terms an autopsy on a human body. ● Vesalius published his influential book about human anatomy “De Humani Commis Fabrica” (The Structure of The Human Body) in 1543. ● It contained over 200 anatomical illustrations…
comparative anatomy predates the modern study of evolution. Early evolutionary scientists like Buffon and Lamarck used comparative anatomy to determine relationships between species. Organisms with similar structures, they argued, must have acquired these traits from a common ancestor. Today, comparative anatomy can serve as the first line of reasoning in determining the relatedness of species. However, there are many hidden dangers that make it necessary to support evidence from comparative anatomy with…
