These structures embryologically originate from the epidermis and can extend down through the dermis into the hypodermis. Many of the organs have specialized cells and glands that secrete fluids and many of the organs are also lined with smooth muscle.

3 Acinar cells that secrete and transport enzymes or bicarbonate into the duodenum for the digestion of the food.
. Clockwise from nervous tissue LM 872 LM 282 LM 460 LM 800. As animals became more complex specific organs and organ systems developed to support specific functions for the organism. Hair is a keratinous filament growing out of the epidermis.
These accessory organs of digestion play key roles in the digestive process. It playa a role in the secretion of lubricants that lubricate and protect the intestinal wall from digestive enzymes. Nerve cells are long thin and covered in myelin natural insulation.
Nerve cells conduct impulses which are used to communicate. The muscle layer has tiny folds which contain villi which are small projections from the epithelial lining. The reproductive structures that evolved in land animals allow males and females to mate fertilize internally and support the growth and development of offspring.
Islets of Langerhans a cell cluster secretes insulin and glucagon hormones that affect blood sugar levels directly into a capillary network that is connected with the. Structure composed of lymphoid tissue located in the nasopharynx pharynx region of the conducting zone that forms a tube of skeletal muscle lined with respiratory epithelium. Accessory structures of the skin include the hair nails sweat glands and sebaceous glands.
The mucosa is the innermost layer of the intestinal track. Hepatic artery - brings oxygenated blood to the liver tissues. It performs hundreds of essential functions.
Nails also made of dead keratinized cells protect the extremities of our fingers and toes from mechanical damage. That is they are homologous structures. Red blood cells are flat and discoid-shaped.
These structures embryologically originate from the epidermis and are often termed appendages. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal. Theyre basically the telephone wires of the body and they look the part.
The outermost layer is smooth muscle middle is connective tissue and the inner layer is epithelial tissue. They can extend down through the dermis into the hypodermis. Accessory structures of the skin include hair nails sweat glands and sebaceous glands.
An organ is made of several types of tissue and therefore several types of cells Cells Often thought of as the smallest unit of a living organism a cell is made up of many even smaller parts each with its own function. Islet cells that secrete insulin or glucagon that increase the glucose level in the blood. Connective tissue stroma - continuous w Glisson capsule blood vessels nerves lymphatic vessels and bile ducts travels within this CT Sinusoidal capillaries - vascular channels between plates of hepatocytes.
Perisinusoidal Disse spaces - lie between the sinusoidal endothelium and hepatocytes. Tissues that produce a penis in males produce a clitoris in females. It is made up of three layers.
Describe human male and female reproductive anatomies. Hair is made of dead keratinized cells and gets its color from melanin pigments. 1 Tissues in the intestinal tract made up of loose connective tissues.
Acinar cells and specialized cells can produce digestive. Accessory structures of the skin include hair nails sweat glands and sebaceous glands. Pancreas Acinar cells create digestive enzymes that are secreted into tiny ducts that feed into a main pancreatic duct.
The four types of tissues are exemplified in nervous tissue stratified squamous epithelial tissue cardiac muscle tissue and connective tissue in small intestine. Describe the common tissues and structures found in accessory organs. This layer comes in contact with the chyme.
Muscle cells are thick and elongated like live rubber bands. The salivary glands liver and gall bladder and the pancreas aid the processes of ingestion digestion and absorption. The hair is a keratin structure growing out of the epidermis.
Most of the male reproductive system is located outside of the body external structures and includes penis scrotum epididymis and testes. The tissue that will become the scrotum in a male becomes the labia in a female. These organs participate in digestion by secreting their substances into the gastrointestinal tract through ducts accessory organs of digestion this is located on the right side of the body inferior to the diaphragm.
4 points - There are many different accessory organs in the gastrointestinal tract that help aid digestion. It contains nerves blood vessels and elastic fibers with collagen. Portal vein - brings nutrient rich blood from the GI tract to the liver.
Accessory digestive organs have common specialized cells ducts and secrete digestive hormones to help in digestion. Organs are the bodys recognizable structures for example the heart lungs liver eyes and stomach that perform specific functions. Describe the structure of the liver.
Accessory structures of the skin include hair nails sweat glands and sebaceous glands. Located between the nasal conchae and the esophagus and trachea philtrum concave surface of the face that connects the apex of the nose to the top lip pulmonary surfactant. It is primarily made of dead keratinized cells.
These structures embryologically originate from the epidermis and can extend down through the dermis into the hypodermis. Describe the basic tissue structure of these digestive accessory organs.
