There are alveoli in your lungs and in your mouth.
mammary alveolus
The bony socket that surrounds the tooth root is called the alveolus, or dental alveolus. This socket is part of the jawbone and provides support and stability for the tooth. The alveolus is lined with a layer of tissue called the periodontal ligament, which helps anchor the tooth in place.
Metastasis
The mouth is the part of a river of stream where it meats a sea or ocean.
They are called neurons.
the nostrail trachea bronchi lungs alveolus diaphrarm
The respiratory system does not contain any structure that filters air. The trachea and bronchus are lined with a mucous membrane that helps trap debris and carry it out of the body, but this is not a filtration system.
Metastasis
Moving of a body part toward the main axis of the body is called adduction. Moving away from the main axis of the body is called abduction.
The muscles that bring a body part toward the body are called adductor muscles. They are responsible for moving a part of the body closer to the midline.
Tissue transplanted from one part of the body to another in the same individual. Also called an autotransplant.
Those people are called plastic or reconstructive surgeons. They perform skin graft procedures where skin from one part of the body is transplanted to another part to promote healing and reconstruct tissue.
