Respiratory System


respiratory System

carbon dioxide can be blown off, and more oxygen can be absorbed into the bloodstream. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. These include the nose, pharynx, larynx, trachea, bronchi and lungs. Anatomy in invertebrates Insects Air enters the respiratory systems of most insects through a series of external openings called spiracles. Physiology in mammals Edit Ventilation Edit In respiratory physiology, ventilation (or ventilation rate) is the rate at which gas enters or leaves the lung. The converting enzyme also inactivates bradykinin. Industrial, professional items, world psychology, biological: Behavioural genetics, evolutionary psychology. Upon inhalation, gas exchange occurs at the alveoli, the tiny sacs which are the basic functional component of the lungs. The pleurae are important because they help you breathe in and out smoothly, without any friction.

12 Pre-term birth can lead to infants with under-developed lungs. It is important that the air in the alveoli and the blood in the capillaries are very close together, so that oxygen and carbon dioxide can move (or diffuse) between them. 11 In fact, once a pre-mature birth is threatened, every effort is made to delay the birth, and a series of steroid shots is frequently administered to the mother during this delay in an effort to promote lung growth. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product. When the air pressure is high inside the lungs, the air from lungs flow out.

These consist of sternocleidomastoid, platysma, and the scalene muscles of the neck. 8 Mollusks Mollusks generally possess gills that allow exchange of oxygen from an aqueous environment into the circulatory system. 6 Fish In most fish respiration takes place through gills. Normally, a foetus will begin producing surfactant from around 28-32 weeks gestation. Travelling in the opposite direction is carbon dioxide, which crosses from the blood in the capillaries into the air in the alveoli and is then breathed out. At birth, the respiratory system becomes fully functional upon exposure to air, although some lung development and growth continues throughout childhood. The cilia beat in one direction, moving mucus towards the throat where it is swallowed. The sections are the pneumotaxic center, the apneustic center, and the dorsal and ventral respiratory groups.
