Hyaline cartilage is rigid, glassy in appearance, and provides cushioning for smooth joints. Fibrocartilage is fibrous and provides support in high-stress areas, such as the pubic symphysis. Elastic cartilage is flexible and makes up fleshy appendages, such as the nose and ears. 

Homeostasis, or "steady-state" physiology, is the system of feedback loops that enables an organism to create a stable, adaptive environment. For example, the pancreas and the brain together work to regulate the blood sugar levels via the hormones insulin and glucagon.

The four types of tissue are muscular, connective, nervous, and epithelial.

Muscular tissue encompasses skeletal, cardiac, and smooth muscle. Nervous tissue creates the central and peripheral nervous systems (CNS, PNS) and consists of all neurons and glial cells. Epithelial tissue makes up "borders" and lines most organs. Connective tissue generally fills spaces and provides the suspensory matrices for the body, such as bone, fat, blood, and cartilage.

Immovable joints are fused shortly after birth, so that they are no longer functional for articulation. The bones of the skull remain open, joined with strips of cartilage, until an infant has passed through the birth canal. They stay open for a short period, giving the baby's brain room to grow. After the brain has finished its major growth stages, the bones of the skull knit together, forming a protective barrier.

Tendons connect muscles to bones, allowing for the muscle contraction to affect the bone and result in articulation. Tendons are essential to provide articulation and leverage points to for motion and locomotion.

Cartilage does not contain blood vessels. Chondrocytes, the specialized cells of cartilage, are supplied by diffusion, which slows growth and repair. While they do produce collagen, this is not the direct reason for the relatively slow growth of cartilage.

The type of muscle that lines the walls of most blood vessels in the human body is smooth muscle. We are told to make the assumption that the muscle types and cells present in Lorempis marengis are the same, structurally and functionally, as those found in humans. Therefore, the type of muscle that lines the walls of most blood vessels in Lorempis marengis is also smooth muscle.  Blood vessels contain a specific subtype of smooth muscle, called vascular smooth muscle, that helps to regulate the distribution of blood volume throughout the entire body by either appropriately contracting or relaxing to restrict or increase blood flow to various parts of the body to best meet bodily needs (typically oxygen delivery).

Skeletal muscle cells, also known as striated muscles, are the type of muscle cells that make up the larger, weight-bearing muscles of the body. These are not the type of muscle cells that are found within the walls of blood vessels. The biceps muscles are the muscles responsible for flexion of the forearm at the elbow. They are not a type of muscle cell, per se, and they are made up of skeletal muscle cells. 

Cardiac muscle cells are the type of muscle cells that make up the myocardium, or muscle cells of the heart. These are not the type of muscle cells that are found within the walls of blood vessels.

Bronchioles end is clusters of small air sacs, the alveoli, where gas exchange occurs. Gases diffuse through the walls of the alveoli into the capillaries.

As CO₂ is blown off by the lungs, the equilibrium is shifted away from carbonic acid via Le Chatelier's principle. The system is attempting to recapture the lost carbon dioxide by producing more, thus depleting the volume of free carbonic anhydrase. Ultimately, the same principle will shift the equilibrium away from bicarbonate.

Via Le Chatelier's principle, the equilibrium is quickly shifted toward CO₂, however, as the passage details, CO₂ does not build up. Instead, it is blown off via the respiratory system.
