Cutaneous Respiration - skin
o The gaseous exchange between the skin of the frog and the external environment -water and air.
o The skin of the frog is supplied with blood capillaries.
o The skin contains glands called the cutaneous glands, which secrete mucous. This keeps the skin always moist and retains a thin film of water underneath the surface of the skin. This condition enables the exchange of air between the blood vessels and the outside environment. They also resort to cutaneous respiration when they undergo either hibernation or aestivation.
Buccal Respiration - mouth
o When the frog floats on the surface of water or while resting on land they respire through the buccal cavity.
o Atmospheric air is sucked in through the nasal openings when the floor of buccal cavity is lowered.
o In the same manner the air is send out when the cavity rises.
o The alternate lowering and rising of the buccal cavity, buccal respiration is bought about.
o The buccal respiratory system of the frog accounts for 5% of the oxygen intake.
Pulmonary Respiration - lungs
o This type of respiration comprises of: the nasal cavity, buccal cavity, larynx, trachea, a pair of lungs and the alveoli inside them.
o The adult frog has very simple, pinkish, sac like organs called lungs. They are not well developed and are placed in the anterior of the frog's body.
o The numerous sac like structures inside the lung called the alveoli are richly supplied with blood capillaries.
o Pulmonary respiration accounts for 65% of total oxygen intake.
The main organ systems of a horse include the digestive system, respiratory system, circulatory system, nervous system, skeletal system, muscular system, urinary system, reproductive system, and integumentary system. Each of these systems plays a vital role in the overall health and function of the horse.
Aristotle used a classification system based on blood (blooded and bloodless), while Linnaeus used a system based on the number and arrangement of reproductive organs (sexual and asexual).
The main respiratory organ of a lizard is its lungs. Lizards have well-developed lungs that allow them to breathe air efficiently. They also have a unique breathing mechanism that involves the use of muscles to move air in and out of their lungs.
The tracheal system in insects functions to transport oxygen directly to the tissues through a network of tubes called tracheae, eliminating the need for blood to transport oxygen. This system allows for efficient gas exchange, enabling insects to thrive in various environments with high oxygen demands.
A coelom is a space surround by mesoderm. It is used as a sort of cushion for the inner organs. It also allows for the body to bend and move around without possibly harming your inner organs. Also it allows for your organs to expand.
The lungs, nostrils, skin, and vocal sac.
The main organs of the respiratory system are the lungs. The main organs of the circulatory system are the heart, blood, and blood vessels.
The main organs of the respiratory system are the lungs. The main organs of the circulatory system are the heart and blood vessels.
The main organs in the respiratory system are the lungs, pharynx, larynx, trachea, and nasal passages.
No you don't need all the organs in your respiratory system to live you can live with 1 lung.
The main organs of the respiratory system are the nose, pharynx, trachea, bronchi, and lungs.
The nose, lungs and windpipe. These are the main organs involved in breathing.
The heart and blood vessels are the main organs of the circulatory system. The lungs are part of the respiratory system.
The main organ in the respiratory system the lungs.
The respiratory system is a collection of organs that take in oxygen from the air and expel carbon dioxide. The main organs involved in this process include the lungs, diaphragm, trachea, and bronchial tubes.
The main organs involved in the respiratory system are the lungs, bronchi, trachea, diaphragm, and alveoli. The respiratory system is responsible for exchanging oxygen and carbon dioxide between the body and the environment.
Because a system is a group of organs and respiratory has organs.
