Answer 1

Explanation:

1. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
2. Epithelial cells
3. Work in conjunction with mucus glands and cilia to secrete and remove mucus and foreign particles from the nasal cavity.
4. The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.
5. Carbaminohemoglobin is a compound of hemoglobin and carbon dioxide, and is one of the forms in which carbon dioxide exists in the blood.
