What else can I help you with?
Why are the capillary walls thinnest?
to allow gas exchange (oxygen and carbon dioxide)
Insects exchange oxygen and carbon dioxide through?
They exchange them through spiracles.
Describe two wys in which the structure of a capillary is adapted to its function?
Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.
Why do capillaries cover the alveoli?
Capillaries cover the alveoli in order to maximize the area for gas exchange between the lungs and the blood. Carbon dioxide is released from the blood through the capillary walls and into the alveoli, while oxygen is picked up from the alveoli through the capillary walls and into the blood.
Which type of blood vessel allows for oxygen and carbon dioxide to exchange?
Capillaries are the thin-walled vessels that allow oxygen and carbon dioxide exchange. Their thin walls make it easy for gases to diffuse across the membranes.
What insects exchange oxygen and carbon dioxide through?
They exchange them through spiracles.
In which capillary beds does oxygen enter the capillaries and carbon dioxide exit the capillaries?
The capillary bed in the lungs is where the oxygen and carbon dioxide are exchanged.
What does alveoll mean?
A tiny, thin-walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place.
What gas exchange takes place in the capillaries throughout the body?
Oxygen is delivered to, and carbon dioxide is removed from, cells near the capillary.
How do earthworms exchange oxygen and carbon dioxide in their environment?
Earthworms exchange oxygen and carbon dioxide through their skin. They absorb oxygen from the air and release carbon dioxide into the environment through their moist skin. This process is called cutaneous respiration.
What occurs during gas exchange?
External Respiration is where gasses are absorbed into the blood through the alveolar capillary beds. Internal respiration is where the gasses are transferred into the cells from the blood.
The layers through which the respiratory gases diffuse are known as the?
The layers through which respiratory gases diffuse are known as the respiratory membrane. This membrane consists of the alveolar epithelium, basement membrane, and capillary endothelium. The exchange of oxygen and carbon dioxide occurs through this membrane during respiration.
