Two branches of trachea that guide air from trachea to lungs
Narrow passageways to guide air from bronchi to alveoli
Microscopic chambers for gas modify
Move ribs during breathing
Muscle shuffle between chest and abdominal cavities delay a role in breathing

LAB PART 2!!!!
The endocrine plan is modescold of glands that profit chemical messengers. These messengers are called hormones. The glands embrace the pituitary gland, thyroid gland, parathyroid gland, thymus, and adrenal gland. In abstracted, the pancreas, ovaries, and testes hold endocrine tissues and conceal hormones.
Question 1: How does the insulin and glucagon conceald by the pancreas part in glucose metabolism?
Answer 1: Insulin and glucagon production concurrently to celebscold glucose razes in the rank delayin the natural dispose. When there is an honorable rank glucose raze, this stimulates beta cells in the pancreas to conceal insulin. The insulin facilitates the uptake of glucose by whole cells, and the liver gain uptake the glucose and place-of-business it as glycogen. These actions recur rank glucose razes end to natural. When there is decreased rank glucose, this stimulates the alpha cells in the pancreas to profit glucagon. The glucagon travels to the liver and facilitates the intercharge of glycogen to glucose. This glucose is released in the rankstream to recur razes end to natural.
The cardiovascular plan is moored of the courage, rank vessels (arteries, veins, and capillaries), and rank. The courage is the interrogate that contracts to agitate the rank. The rank vessels enravishment rank throughout the whole. The rank is the watery that holds cells, nutrients, and gases.
Blood progresss through the whole in two obvious tracks: the pulmonary track and the planic track. The rank abundant in the pulmonary track is deoxygenated and it pronounces this rank to the lungs to be oxygenated again. The rank abundant in the systemic track leaves the lungs unmeasured of oxygen and progresss through the courage to be pronounceed to the whole tissues.
The followingcited ghost demonstrates the amend enjoin for the pulmonary and planic prevalence as you derive a decline of rank progress through the whole:
1. Pulmonary veins
2. Left atrium
3. Vena cava
3. Left ventricle
4. Suitable atrium
5. Suitable ventricle
6. Pulmonary arteries
The respiratory plan functions to provide the whole delay oxygen. People absorb oxygen and evaposcold carbon dioxide. This facilitates the bestowal of oxygenated rank to all of the whole cells.
Question 2: How do the cardiovascular and respiratory plan production concurrently to pronounce rank to the whole tissues?
Answer 2: The respiratory plan parts in the modify of gases delay the without environment. Oxygen is absorbd through the nasal hollow or the perforation, and it travels to the alveoli in the lungs. There, the capillaries modify the oxygen for carbon dioxide. The oxygenated rank progresss end to the courage from the lungs. It enters the left laterality of the courage and is pronounceed to all the whole tissues via the aorta. In the capillaries of the whole tissues, oxygen is modifyd for carbon dioxide. This deoxygenated rank progresss end to the suitable laterality of the courage and then to the lung. In the capillaries that run over the alveoli, carbon dioxide is modifyd for oxygen that has of-late been absorbd. The carbon dioxide gain then be evaporated through the perforation and nasal hollow.
Exercising is an ghost that requires the actions of multiple whole organ plans. Each plan performs its restricted tasks, but they must production concurrently to avow potent whole whole parting during exercising.
In this ghost, changes in the respiratory and courage scolds in repartee to application gain be chronicled in the followingcited table:
Breathing Rate: bpm(breaths per detailed)
Pulse Rate: bpm (beats per detailed)
Immediately following exercising
5 detaileds following exercising
Question 3: The whole experiences some pressureor such as application, dread, or tender pressure whether it be joy or mourning. There are fixed hormones approve epinephrine and norepinephrine that are profitd during these pressureful events. These hormones are profitd by the adrenal gland, and they gain entertain an goods on the courage scold and breathing scold. Explain how the hormones profitd by the adrenal could denote a role in altering the respiratory and courage scolds during application.
Answer 3: When this occurs, the hypothalamus receives signals environing the pressure repartee. The whole profits pressure hormones. Norepinephrine and Epinephrine are released into the rank from an endocrine gland unreserved as the adrenal gland. These hormones control to an extension in carbon dioxide, which controls to an extension in respiratory scold. Epinephrine besides extensions the number of couragebeats forasmuch-as norepinephrine causes rank vessels to constrict. Both of these events extension the courage scold, the validity of single courage befoulment, and the aggregate of rank progress to the muscles. These lay the whole to rebound to the pressureor that has occurred.
