THE BRONCHIOLES
No, Platyhelminthes lacks a circulatory system and a respiratory system.
Cartilage is a flexible connective tissue found in various parts of the body, such as the joints, ribs, and ears. It provides structure and support while being more flexible than bone. Cartilage lacks blood vessels, nerves, and lymphatics, which affects its ability to repair and heal compared to other tissues.
One vertebrate that lacks a bony spine is the shark. Many different types of shark have cartilage instead of bones.
A haemal system is a network of vessels found in certain invertebrates that functions in circulation. It helps transport nutrients, gases, and waste products throughout the organism's body.
The bacterium would be less likely to colonize the patient's lower respiratory system.
A tissue that lacks a blood supply and heals very slowly is referred to as avascular tissue. Examples include cartilage and cornea. These tissues rely on diffusion of nutrients and oxygen from surrounding tissues for repair and maintenance.
Steam has the capacity to flow through the system without support of external energy sources like pumps. However, it lacks modulating quality
Cartilage is a connective tissue due to its composition of specialized cells (chondrocytes) embedded in an extracellular matrix of collagen and proteoglycans. It also provides structural support, flexibility, and cushioning between bones in joints. Additionally, it lacks blood vessels and nerves, characteristics common to connective tissues.
Cartilage tissue contains a specialized matrix composed of collagen fibers, proteoglycans, and water. It lacks blood vessels and nerves, and primarily receives nutrients and removes waste through diffusion. Cartilage cells called chondrocytes are responsible for maintaining the extracellular matrix.

Cartilage is a connective tissue that is avascular, meaning it lacks blood vessels. It relies on diffusion for nutrient exchange and waste removal.
Compact bone is more organized than hyaline cartilage. Compact bone is dense and composed of repeating structural units called osteons, while hyaline cartilage is a type of connective tissue that is less organized and lacks a regular structural pattern.
