A decreased respiratory drive can also be the result of metabolic alkalosis, a state of decreased carbon dioxide in the blood; Central sleep apnea. During sleep, the breathing centers of the brain can pause their activity, leading to prolonged periods of apnea with potentially serious consequences. Hyperventilation followed by prolonged breath ...
The tunicate epicardium separates digestive organs from the pharynx and heart, but the anus returns to the upper compartment to discharge wastes through an outgoing siphon. Thus the diaphragm emerges in the context of a body plan that separated an upper feeding compartment from a lower digestive tract, but the point at which it originates is a ...
Decreasing metabolic rate by reducing body temperature lowers oxygen demand and consumption, and can minimise the effects of tissue hypoxia, especially in the brain, and therapeutic hypothermia based on this principle may be useful. [8] Where the problem is due to respiratory failure. it is desirable to treat the underlying cause.
Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration. [1] The most important function of breathing is the supplying of oxygen to the body and balancing of the carbon dioxide levels.
The diaphragm is the major muscle responsible for breathing. It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward).
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...

The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
