Thank you Niccolo amazing images!

Incisors

Incisors

Incisors are sharp, flat-edged teeth located at the front of the mouth. They are used for cutting and biting into food.

Canine

Canines, also known as cuspids, are the pointed teeth located on either side of the incisors. They are used for tearing and grasping food.

Carnassial

Carnassial teeth are specialized molars found in carnivorous animals, such as minks. They have sharp, shearing edges that are used for slicing and shearing meat.

Mouth

The mouth is the opening where food enters the digestive system. It contains the teeth, tongue, and salivary glands. The mouth plays a vital role in chewing and beginning the process of digestion through saliva production.

If you need a picture for this just drop the class tbh (just kidding)

Pharynx

The pharynx is a muscular tube located behind the mouth and nasal cavity. It serves as a passageway for both food and air, directing food into the esophagus and air into the larynx and trachea.

Larynx

The larynx, also known as the voice box, is located at the upper part of the trachea. It contains the vocal cords and plays a crucial role in producing sound and facilitating breathing.

Trachea

The trachea, or windpipe, is a tube connecting the larynx to the bronchial tubes in the lungs. It allows the passage of air during inhalation and exhalation.

Esophagus

The esophagus is a muscular tube that connects the pharynx to the stomach. It carries food from the mouth to the stomach through rhythmic contractions called peristalsis.

Cardiac Sphincter

The cardiac sphincter, also known as the lower esophageal sphincter, is a circular muscle located at the entrance of the stomach. It prevents stomach acid and partially digested food from flowing back into the esophagus.

Lungs

The right apical lobe and left apical lobe are the uppermost parts of their respective lungs, while the right cardiac lobe is in the middle of the right lung. The left diaphragmatic lobe and right diaphragmatic lobe are the lowermost parts of the left and right lungs, respectively. The intermediate lobe is a unique lobe found between the right apical and right diaphragmatic lobes in some individuals. Together, these lobes contribute to respiratory functions and gas exchange in the lungs.

Stomach

The stomach is divided into three main regions: pyloric, cardiac, and fundic. The pyloric region contains the pyloric sphincter, regulating the passage of partially digested food to the small intestine. The cardiac region contains the cardiac sphincter, preventing the backflow of stomach contents into the esophagus. The fundic region is responsible for storing and mixing food with gastric secretions.

Pyloric Sphincter

The pyloric sphincter is a muscular valve located at the exit of the stomach, leading to the small intestine. It regulates the flow of partially digested food (chyme) from the stomach into the small intestine.

Greater and Lesser curvature

The greater and lesser curvatures are the outer borders or contours of the stomach. The greater curvature is the convex outer curve, while the lesser curvature is the concave inner curve.

Greater and Lesser Omentum

The greater and lesser omentum are folds of connective tissue that hang from the stomach and cover the abdominal organs. They provide support and protection for the organs and also play a role in immune response.

Rugae

Rugae are ridges or folds in the inner lining of the stomach. They allow the stomach to expand and contract as it accommodates food and aids in mechanical digestion.

Thymus

The thymus is a gland located in the chest, near the heart. It plays a crucial role in the development and maturation of certain immune cells called T-cells, which are essential for the immune system's functioning.

Pericardium

The pericardium is a sac-like structure that surrounds and protects the heart. It consists of two layers, the outer fibrous pericardium and the inner serous pericardium. The pericardium helps prevent friction between the heart and surrounding structures.

Heart

The heart is a muscular organ responsible for pumping blood throughout the body. It consists of four chambers: the right and left atria and the right and left ventricles. The heart receives deoxygenated blood from the body and pumps oxygenated blood to the body's tissues.

R & L Auricles

The right and left auricles, also known as atria, are the upper chambers of the heart. They receive blood returning to the heart and transfer it to the ventricles.

R & L Atria

The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. Both atria contract to pump blood into the respective ventricles for further circulation.

R & L Ventricles

The right and left ventricles are the lower chambers of the heart. They receive blood from the atria and pump it out to the lungs and body.

Interventricular sulcus

The interventricular sulcus is a groove that separates the left and right ventricles on the outer surface of the heart.

Aortic Arch

The aortic arch is a curved portion of the main artery called the aorta. It bends over the heart and gives rise to branches that supply oxygenated blood to the head, neck, and upper limbs.

Thoracic Aorta

The thoracic aorta is the portion of the aorta located within the chest. It supplies oxygenated blood to the organs and tissues of the thoracic cavity.

Abdominal Aorta

The abdominal aorta is the portion of the aorta located within the abdomen. It supplies oxygenated blood to the organs and tissues of the abdominal region.

Falciform ligament

A thin, crescent-shaped ligament that attaches the liver to the anterior abdominal wall, separating the right and left lobes of the liver.

Liver

A large, reddish-brown organ located in the upper right portion of the abdomen. It plays a vital role in various metabolic processes, including detoxification, protein synthesis, and production of bile.

Gallbladder

A small, pear-shaped organ located beneath the liver. Its function is to store and concentrate bile produced by the liver, releasing it into the small intestine to aid in the digestion and absorption of fats.

Spleen

A soft, purplish organ located on the left side of the abdomen. It serves as part of the immune system, filtering blood, and removing old or damaged red blood cells.

Pancreas

A glandular organ located behind the stomach. It has both endocrine and exocrine functions, producing digestive enzymes to break down food in the small intestine and releasing hormones, such as insulin, to regulate blood sugar levels.

Mesenteries

Sheets of thin, membranous tissue that suspend and support the organs in the abdominal cavity. They provide a pathway for blood vessels, nerves, and lymphatics and also help to hold the organs in place.

Small Intestines

The small intestine is divided into three regions: duodenum, jejunum, and ileum. The duodenum is the first part where the majority of digestion takes place, while the jejunum and ileum are primarily involved in the absorption of nutrients.

Villi

Tiny, finger-like projections present in the lining of the small intestine. They increase the surface area for absorption, allowing nutrients to be efficiently taken up by the body.

Duodenum

The initial segment of the small intestine that receives partially digested food from the stomach. It plays a crucial role in the breakdown of food through the action of digestive enzymes.

Large Intestines
