Glandular epithelial tissue:
Glandular epithelial cells make up any glands within the body. These include sebaceous glands of the skin and glands in the intestinal lining (exocrine glands), and many of the endocrine glands releasing hormones, such as the thyroid follicle.
The function of glandular epithelial cells is directly related to their location. Exocrine glands hold secretions for linings and coverings of the body until the secretions are needed, at which time the cells follow the above secretion mechanisms.

The midbrain is the portion of the brainstem that connects the hindbrain and the forebrain. This region of the brain is involved in auditory and visual responses as well as motor function.
The hindbrain extends from the spinal cord and is composed of the met encephalon and myelecephalon.

Function of the respiratory system:
Your respiratory system is made up of the organs in your body that help you to breathe. The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide.
The respiratory system also is vital in maintaining normal blood pH and body temperature
All the body cells metabolically consume oxygen, and discharge carbon dioxide. To cover this need, respiration takes place internally (at the cellular level) and externally (ventilation/breathing). Ventilation involves the inhalation of atmospheric air into the lungs via the nose and mouth through branching passageways, and the exhalation of carbon dioxide.
The lung key function is to bring air and blood into inside contact in the alveolar air sacs so that oxygen can enter the blood, and carbon dioxide can leave.

A plasma membrane protects the interior contents present in the cell from spilling out into the external environment and also protects the cell from harmful substances present in the external environment from entering into the cell.
A plasma membrane maintains shape and rigidity to protect the cell aiding its survival by controlling and regulating what chemicals enter and leave the cell due to the selective permeable nature of plasma membrane.
The nucleus contains DNA in the form of chromosomes. The DNA gets transcribed into mRNA, which is translated by the ribosome’s into proteins. When a certain function is needed in the cell, cellular signals (proteins, hormones, etc) will activate transcription, leading to the production of proteins that will perform the necessary function.
The Endoplasmic Reticulum is like the cell 's passage way; the Golgi apparatus package and tag protein products so that they safely get where they need to go.
Secretor vesicles only exist transiently in the cell and are part of the end membrane system that shuttle newly synthesized proteins within the
