The snorkel tube is 35.0 cm in length and 1.4 cm in radius. How does this affect Omar's breathing? Calculate the increase in relative resistance contributed by the snorkel tube. b. What is dead space and how does that affect snorkeling? Explain your answer, assuming the snorkel tube is a round cylinder and cylinder volume is πr²L. How does the snorkel tube affect alveolar ventilation (assume a ventilation rate of 13 breaths/ min, tidal volume of 600 mL, and normal dead space volume of 150 mL.)? If normal alveolar ventilation is 4200 mL/min, how must Omar breathe during snorkeling compared to normal? c. Omar loves snorkeling, but wishes he could go a little deeper. He decides to create a longer snorkel tube to try to achieve this desire. He isn't sure how radius figures in, so he makes two tubes of 80 cm length, one with a 1.6 cm radius and the other with a 2.2 cm radius. What are the relative resistances of these two new tubes? Do you think he will be able to snorkel well with either of these tubes? Explain.
Histology
Histology is the microanatomy method and a branch of biology that studies the anatomy of tissues. It includes viewing tissue in a magnified view under the microscope. Microanatomy also includes the process of study of organs called organology and the study of cells called cytology. Histopathology is a branch of biology that includes microscopic identification of diseased tissue. The field of histology comprises the preparation of the tissues and collection of cells as specimens for examination under the microscope. These processes are done by technicians like histologists, histotechnicians, and biomedical scientists. Histopathology is the diagnosis and research of tissue diseases that require the examination of tissues and/or cells under a microscope. Histopathologists are in charge of determining tissue diagnosis and assisting clinicians in managing a patient's care.
Endocrine System
Human body functions due to the collective work of the organ systems. One of them is the endocrine system. It is a chemical messenger system constituting the hormones directly released by the endocrine glands into the circulatory system. The study of this system is known as endocrinology. The word 'endon' means inside, and 'crine' means secrete, making the word "endocrine."
