WebSwimming. Marine mammals have several adaptations for swimming. An obligate swimmer is any species that spends its entire life in water. All whales and dolphins are obligate swimmers. Unlike pinnipeds, otters, and polar bears, cetaceans cannot survive on land for extended periods of time. Similarly, all sirenians are obligate swimmers. Web22 de fev. de 2024 · Adaptations of the alveoli: Moist walls – gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls – allow gases to pass through. Extensive blood supply – ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
WebTracheal System of an Insect. All insects possess a rigid exoskeleton with a waxy coating that is impermeable to gases. Insects have evolved a breathing system that delivers oxygen directly to all the organs and tissues of their bodies. A large number of tracheoles run between cells and into the muscle fibres - the site of gas exchange. WebThe lungs are divided into bronchi, and the bronchi are divided into bronchioles. The alveoli are small, round, or balloon-like structures at the ends of the bronchioles that increase …
