Answer:
Endocardium: is the innermost layer of the heart.
Myocardium: is the muscle layer
Pericardium: is a double-wall sac that cointains the heart.
Explanation:
While the Pericardium protects the heart against infection, provides lubrication and fixes it to the mediastinum, the Myocardium is the middle layer from the heart and the thickest one. It has specialized muscle fibers that carry electrical impulses to the ventricles. It is the muscle layer comprised of cardiomyocytes. The endocardium is comprised of two layers: the inner one is made of endothelial cells and the second one is a subendocardial connective tissue where branches of the heart's conduction system are inmersed.
I think it means Heart/Lungs.
Cardio = Heart
Respiratory= Lungs
The following are the ways to keep the lungs free of germs and dirt from the air:
Mucus found in the bronchial tubes collects dirt and germs that gets into your lungs.
Tiny hairs called cilia work to sweep out the debris collected to keep your lungs clean.
<u>Explanation</u>:
The lungs are air-filled organs that are responsible for breathing. Lungs are located on either side of the chest. Exposure to pollutants should be avoided to maintain the lungs healthy and clean.
Cilia are tiny hair-like cell structure that is located on the surface of the cells. These tiny hairs help in sweeping out the collected debris to keep the lungs clean.
Mucus is a substance secreted by the mucous membranes and is found in the bronchial tubes. The dirt and germs are collected by mucus and prevents that from passing into the lungs.
