what are the major organs in the respiratory system and their functions?

These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.

Lung tissue consists mainly of alveoli (Figure 16.2. 6). These tiny air sacs are the functional units of the lungs where gas exchange takes place. The two lungs may contain as many as 700 million alveoli, providing a huge total surface area for gas exchange to take place.

The nose and paranasal sinuses are part of the upper respiratory tract. The functions of the nose include the sense of smell and conditioning of inhaled air by warming it and making it more humid. Hairs inside the nose prevent large particles from entering the lungs.

Anatomy & Physiology. The Anatomy and Physiology module introduces the structure and function of the human body. You will read about the cells, tissues and membranes that make up our bodies and how our major systems function to help us develop and stay healthy.

The respiratory and digestive systems work together to power the body. A properly functioning respiratory system delivers adequate oxygen to the blood. Because the digestive system breaks down food and uses muscular contractions to move food through the digestive tract, it needs oxygen to function properly.

Although the urinary system has a major role in excretion, other organs contribute to the excretory function. The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water. The skin is another excretory organ that rids the body of wastes through the sweat glands.

The Role of the Respiratory System is to breathe in oxygen and breathe out carbon dioxide. This is known as respiration. The cells of the body use oxygen to perform functions that keep us alive. The waste product created by the cells once they have performed these functions is carbon dioxide.

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.

There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body's exterior.

The skeletal system provides structure to soft tissue in the upper respiratory tract. The respiratory and nervous systems work together to identify odors in your environment. The respiratory system communicates with the nervous system through foramina in the ethmoid bone.

There are 11 major organ systems in the human body, which include the circulatory, respiratory, digestive, excretory, nervous and endocrine systems. The immune, integumentary, skeletal, muscle and reproductive systems are also part of the human body.

Organs are the body's recognizable structures (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions. An organ is made of several types of tissue and therefore several types of cells.

In summary, the human body is made of 11 important organ systems, including the circulatory, respiratory, digestive, excretory, nervous and endocrine systems. They also include the immune, integumentary, skeletal, muscle and reproductive systems. The systems work together to maintain a functioning human body.
