villi
Intestinal villi are small, finger-like projections that extend into the lumen of the small intestine
kidneys
The kidneys are bean-shaped organs that serve several essential regulatory roles in vertebrates
liver
The liver is a vital organ of vertebrates and some other animals
epididymis
The epididymis is a tube that connects a testicle to a vas deferens in the male reproductive system
gametes
A gamete is a cell that fuses with another cell during fertilization in organisms that sexually reproduce
testes
The testicle is the male gonad in animals
cervix
The cervix or cervix uteri is the lower part of the uterus in the human female reproductive system
embryo
An embryo is an early stage of development of a multicellular diploid eukaryotic organism
medulla
The medulla oblongata is located in the hindbrain, anterior to the cerebellum
ovaries
The ovary is an ovum-producing reproductive organ, often found in pairs in the female as part of the vertebrate female reproductive system
uterus
The uterus or womb is a major female hormone-responsive reproductive sex organ of most mammals, including humans
dermis
The dermis or corium is a layer of skin between the epidermis and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain
epidermis
The epidermis is the outer of the two layers that make up the skin , the inner layer being the dermis
subcutis
The subcutaneous tissue , also called the hypodermis, hypoderm , subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates
joints
A joint or articulation is the connection made between bones in the body
meniscus
In anatomy, a meniscus is a crescent-shaped fibrocartilaginous structure that, in contrast to an articular disk, only partly divides a joint cavity
AV valves
A heart valve normally allows blood to flow in only one direction through the heart
gas exchange
Gas exchange is a biological process through which different gases are transferred in opposite directions across a specialized respiratory surface
esophagus
The esophagus or oesophagus , commonly known as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach
