Explanation:WOMEN
Age 50 & younger 1,000 mg* daily
Age 51 & older 1,200 mg* daily
MEN

Answer:
Irregular, short, long, and flat
Explanation:
Having stronger bones
Easier to do household chores
Lower blood pressure
Larger lung capacity
The heart, the blood vessels, and the veins are the components that carry oxygen from the heat to all parts of the body
Alveoli is the smallest part of the respiratory system. The best description about it is “they are the smallest tubes in the respiratory system”.
EXPLANATION
Alveoli’s function is to exchange oxygen and carbon dioxide. Thus, it becomes an important part of the respiratory system. Alveoli’s shape is like tiny balloon-shaped. Its location is at the very end of the respiratory tree. It is arranged in clusters which are throughout the human’s lungs. Alveoli also can be said as the endpoint of the respiratory system. Without alveoli, a human cannot breathe normally.
Due to the important function of alveoli, here are some medical conditions that people have to be aware of:
• Emphysema
• Pneumonia
• Tuberculosis
• Bronchioloalveolar carcinoma
• Acute respiratory distress syndrome
• Respiratory distress syndrome
• Pulmonary edema
We also have to be aware of the effect of tobacco and smoking because these things can affect the function of alveoli. Tobacco and smoking cause the damage, right down to the molecular level. It will disrupt our body’s ability to repair itself. In a serious condition, it will lead to an infection or trauma. The effect of tobacco and smoking also cause a risk to human’s lungs. The damage of the alveoli will cause human’s lungs exposed to the toxic fumes.
