Out with the old and in with the new—that's what the respiratory system does, delivering air to the lungs, bringing oxygen into the body, and expelling the carbon dioxide back into the air. Understanding the structure and intricacies of the respiratory system is vital to human anatomy. The respiratory system is made up of more than just the lungs; it also includes your nose, throat, larynx, windpipe, bronchi, alveolar ducts, and respiratory membrane.The function of the respiratory system is to deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs. Respiration includes the following processes:
External respiration is the process of gas exchange between the atmosphere and the body tissues. In order to accomplish this task, the following events occur:
1.Pulmonary ventilation is the process of breathing—inspiration (inhaling air) and expiration (exhaling air).
2. Gas transport, carried out by the cardiovascular system, is the process of distributing the oxygen throughout the body and collecting CO 2 and returning it to the lungs.
Internal respiration is the process of gas exchange between the blood, the interstitial fluids (fluids surrounding the cells), and the cells. Inside the cell, cellular respiration generates energy (ATP), using O 2 and glucose and producing waste CO 2.
Answer:
The correct answer is option D. loss of calcium.
Explanation:
The appropriate protein intake in an average person is 0.8 gm per kg of body weight. By calculating it is clear that he is taking a very high amount of protein that can lead to many negative impacts and one of them is the loss of calcium.
Studies have suggested that protein intake in high amounts can lead to an increase in urinary excretion of calcium.
Thus, the correct answer is option D. loss calcium.
The answer is D this help flex the neck and rotate the head upwards and side to side.
It is important to help people who don’t have food because they can die or starvation or dehydration. The human body is 60% water. 79% muscles and kidneys, 64% skin, and 73% brain and heart. If the people don’t have food their percentage will decrease.
Other benefits you receive from physical activity is that it strengthens your mind, slows aging and helps you have more of a positive feeling.
