Do flatworms have respiratory system?

Do flatworms have respiratory system?

Flatworms have no specialized respiratory system; gases simply diffuse across the body wall.

How is respiration in aquatic animals is different from respiration in humans?

Respiration in aquatic plants is different from that of humans because there is small amount of oxygen dissolved in water as compared to the amount of oxygen present in air, So respiration in Aquatic animals are much faster than terrestrial animals ( humans also ).

What is human respiration?

The process of getting oxygen into the body and releasing carbon dioxide is called respiration. Breathing is only the movement of oxygen into the body and carbon dioxide out of the body. The process of respiration also includes the exchange of oxygen and carbon dioxide between the blood and the cells of the body.

What are different respiration process in different organism?

External Respiration or Breathing This is mainly two phases. Inspiration: It is the process by means of which oxygen is taken to the lungs. Expiration: During expiration, carbon dioxide is expelled out from the respiratory organs into the environment.

What are 4 types of respiration?

Respiration consists of 4 distinct processes:

• Pulmonary Ventilation. moving air into and out of the lungs.
• External Respiration.
• Transport. transport of oxygen and carbon dioxide between the lungs and tissues.
• Internal Respiration. diffusion of gases between the blood of the systemic capillaries and cells.

What is the type of respiration?

There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic).

What type of respiration requires oxygen?

Aerobic respiration

What is a normal respiration rate?

Normal respiration rates for an adult person at rest range from 12 to 16 breaths per minute.

What does respiratory rate indicate?

Respiratory rate (RR), or the number of breaths per minute, is a clinical sign that represents ventilation (the movement of air in and out of the lungs). A change in RR is often the first sign of deterioration as the body attempts to maintain oxygen delivery to the tissues.

What is the average number of breaths per minute for CPR?

After every 30 chest compressions at a rate of 100 to 120 a minute, give 2 breaths. Continue with cycles of 30 chest compressions and 2 rescue breaths until they begin to recover or emergency help arrives.
