There are six major types of connective tissue in vertebrates.

Adipose tissue is an example of fibrous connective tissue.

In pseudo-stratified epithelia, the cells are so crowded that the nuclei become aligned in one row.

Adipose tissue is a type of dense connective tissue that stores fat.

Osteoblasts mature into osteocytes as new bone is formed.

Cartilage is a rigid and inflexible support material.

Osteoclasts release an acid to dissolve calcium and phosphate ions in bones.

The combination of hard minerals and flexible collagen makes bone softer than cartilage.

Chondroblasts produce chondrocytes and the extracellular matrix of cartilage.

Chondrocytes are found in the matrix of cartilage, maintaining it by secreting collagen and elastin.

Cartilage is a rigid support material due to the presence of elastic fibers within its structure.

In humans, cartilage can be found in the nose, ears, and part of the rib cage only.

The matrix of cartilage is primarily made up of a substance called keratin sulfate.

Increasing the surface area of the small intestine allows for a higher diffusion rate, leading to higher absorption of nutrients.

Diffusion is most effective over long distances within an organism.

An organism's size can be limited by the effectiveness of diffusion in transporting nutrients and gases across its body.

The absence of microvilli on the small intestine would result in faster absorption of nutrients due to reduced surface area.

In the context of absorption, diffusion rate in the small intestine is inversely correlated with surface area.

To counteract the limitations imposed by diffusion in nutrient absorption, organisms have evolved structures like microvilli to increase surface area.

Positive feedback loops play a major role in maintaining homeostasis in organisms.

During childbirth, the pressure of the baby's head against sensors near the opening of the uterus triggers negative feedback loops.

Smooth muscles are more prone to atrophy than skeletal muscles when a person leads a sedentary lifestyle.

Negative feedback loops are commonly used by organisms to regulate variables such as blood pressure and blood pH.

Positive feedback brings about a gradual decline in a particular trend.

The failure of a set point in conditions like diabetes highlights the importance of positive feedback in maintaining homeostasis.
