What are the 4 main structures of the skin?
The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
What are the different types of capillaries?
The 3 types of Capillaries
- Continuous capillaries. These are the most common types of capillaries.
- Fenestrated capillaries. Fenestrated capillaries are “leakier” than continuous capillaries.
- Sinusoid capillaries.

What are the three different types of capillaries and how do they differ functionally?
For capillaries to function, their walls must be leaky, allowing substances to pass through. There are three major types of capillaries, which differ according to their degree of “leakiness:” continuous, fenestrated, and sinusoid capillaries.
What is the most common type of capillary?
Continuous capillaries
Continuous capillaries are the most common type of capillary in your body. Like other blood vessels, they have a lining made up of a type of cell called endothelial cells.
What is the inner layer of the skin?
subcutis
The subcutis is the innermost layer of the skin, and consists of a network of fat and collagen cells. The subcutis is also known as the hypodermis or subcutaneous layer, and functions as both an insulator, conserving the body’s heat, and as a shock-absorber, protecting the inner organs.
What is the 5 layers of the epidermis?
The layers of the epidermis include the stratum basale (the deepest portion of the epidermis), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum (the most superficial portion of the epidermis).
