Question

Почему кровь у насекомых не участвует в газообмене?

Answer 1

Кровьунасекомых доставляет кислород к тем тканям и клеткам куда не доходят трахеоллы , а так же кислород потребляют сами клетки крови. Так же клетки кровиучаствуетв удалении СО2.

Answer 2

Возможно потому что у насекомых не развита кровеносная система т.к дышат они с помощью разветвленных трубочек,которые заканчиваются отверстиями на поверхности тела. поэтому им не нужен тот кислород,который как у человека поступает вместе с кровью..

Answer 3

Why doesn't blood participate in gas exchange in insects?

Insects have a unique respiratory system that differs from mammals and other vertebrates. Instead of relying on blood for gas exchange, insects have a specialized network of tubes called tracheae that directly deliver oxygen to their tissues. This system allows for efficient gas exchange without the need for blood involvement.

The tracheal system in insects consists of a network of tiny tubes that branch throughout the insect's body, delivering oxygen directly to the cells. These tubes open to the outside through small openings called spiracles, which are located on the insect's body surface. Oxygen enters the spiracles and travels through the tracheae, reaching the cells where it is needed for respiration. Similarly, carbon dioxide, the waste product of respiration, diffuses out of the cells and exits the body through the same system.

The absence of blood involvement in gas exchange in insects is advantageous for several reasons. First, it allows for a more efficient exchange of gases. Oxygen can be delivered directly to the cells without the need for it to be transported through the circulatory system. Second, it eliminates the need for a specialized respiratory pigment, such as hemoglobin, which is responsible for carrying oxygen in the blood of vertebrates. Insects do not require a respiratory pigment because oxygen is delivered directly to the cells through the tracheal system.

It's important to note that while blood does not participate in gas exchange in insects, it still plays a vital role in other physiological processes, such as nutrient transport, waste removal, and immune responses.
