Respiratory of the human body

This body plan is most clearly evident in the embryo ; by birth, the plan is apparent only in the trunk region—i.

This allows a movement similar to the "pump handle effect", but in this case it is called the bucket handle movement.

There the cells absorb the oxygen from the red blood cell and pass on their waste carbon dioxide. CPAPor continuous positive airway pressure, in which a controlled air compressor generates an airstream at a constant pressure.

It then enters the lungs where it is exhaled into the atmosphere. During heavy breathing, exhalation is caused by relaxation of all the muscles of inhalation.

The Respiratory and Circulatory System in the Human Body

Thus the animal is provided with a very special "portable atmosphere", whose composition differs significantly from the present-day ambient air. The arteries take the blood from the heart out to the different organs. The surface tension of a watery surface the water-air interface tends to make that surface shrink.

Proteins also serve as a major structural component of the body. The driving pressure forcing air into the lungs during inhalation is therefore halved at this altitude.

The color of the ribs refers to their classification, and is not relevant here. This ensures that equilibration of the partial pressures of the gases in the two compartments is very efficient and occurs very quickly. Hemoglobin can also carry a small amount of carbon dioxide from the tissues back to the lungs.

The urinary system also called excretory system or the genitourinary system is the organ system that produces, stores, and eliminates urine. The upper airway system comprises the nose and the paranasal cavities or sinusesthe pharynx or throatand partly also the oral cavitysince it may be used for breathing.

The Left Primary Bronchus has the same setup as the right with the lobar, segmental bronchi and the bronchioles. Upper Respiratory Tract Infections[ edit ] The upper respiratory tract consists of our nasal cavities, pharynx, and larynx.

External Respiration[ edit ] External respiration is the exchange of gas between the air Respiratory of the human body the alveoli and the blood within the pulmonary capillaries. The respiratory system is divided into two main components: When a doctor puts hisor her hand on your shoulder or back and looks at the clock, they are keeping track of how many times you breathe within one minute.

The body wall forms the cylinder. This is called expiratory reserve volume and is about ml of air. In the dorsal part of the body they are temporary; in the ventral part they become permanent, forming the two pleural cavities, which house the lungs; the peritoneal cavity, which contains the abdominal organs; and the pericardial cavity, which encloses the heart.

There are three factors in this process: When a person inhales, the lungs expand and fill with fresh air. To exhale air, the diaphragm and external intercostal muscles relax while the internal intercostal muscles contract to reduce the volume of the thorax and increase the pressure within the thoracic cavity.

They also release a variety of substances that enter the systemic arterial blood, and they remove other substances from the systemic venous blood that reach them via the pulmonary artery. Breathing becomes difficult and affected individuals run the risk of choking to death on their own secretions unless strenuous effort is made to clear the lungs multiple times every day.

If you were to spread out flat all of the air sacs in the lungs of an adult, the tissue would cover an area about the third of the size of a tennis court. In this way oxygen is gained and carbon dioxide is lost by the body.

The nasal cavity with its adjacent spaces is lined by a respiratory mucosa. This phenomenal exchange works with the assistance of the red blood cells in your bloodstream. The reduction in the partial pressure of oxygen in the inhaled air is therefore substantially greater than the reduction of the total atmospheric pressure at altitude would suggest on Mt Everest: In such situations, the resultant form is seldom perfect for the new conditions, but it is adapted to present needs well enough to maintain life with the least waste of energy.

Smooth muscle tissue in their walls helps to regulate airflow into the lungs. Furthermore, surfactant deficiency and pulmonary immaturity together leads to alveolar collapse.The human respiratory and circulatory systems work together to supply the body with oxygen and get rid of waste carbon dioxide.

While the former deals with air and the latter with blood, they work together seamlessly by coordinating the functions of the many parts of each system.

You usually don't even notice it, but twelve to twenty times per minute, day after day, you breathe -- thanks to your body's respiratory lungs expand and contract, supplying life.

In this lesson, you'll learn about the 11 organ systems, which are made of multiple organs that work together to keep the human body functioning. The organ systems of the body include the musculoskeletal system, circulatory system, digestive system, endocrine system, integumentary system, urinary system, lymphatic system, immune system, respiratory system, nervous system and reproductive system.
