Answer:
The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus.
In mammals, the digestive tract is made up of multiple organs such as the stomach, pancreas, and intestines. These all work together to form the alimentary canal we use to digest food.
The digestive system in mammals is a complex network of organs and structures responsible for breaking down food into nutrients that can be absorbed and utilized by the body. The digestive tract, also known as the alimentary canal or gastrointestinal tract, consists of several organs that collaborate to facilitate the digestion and absorption process.
Stomach: The stomach is a muscular organ that receives and churns food, mixing it with gastric juices containing enzymes and acids to begin the process of digestion. It plays a crucial role in breaking down proteins.
Pancreas: The pancreas is both an endocrine and exocrine gland. Its exocrine functions involve producing digestive enzymes that are released into the small intestine to further break down carbohydrates, proteins, and fats.
Mouth: The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down carbohydrates.
Esophagus: The esophagus is a muscular tube that carries food from the mouth to the stomach.
Small intestine: The small intestine is the longest part of the digestive tract. It is where most of the nutrients from food are absorbed.
Large intestine: The large intestine is shorter than the small intestine. It absorbs water and salts from food and stores waste products until they are eliminated from the body.
Rectum: The rectum is the last part of the digestive tract. It stores waste products until they are eliminated from the body.
The digestive tract is a vital organ system that is essential for the survival of mammals. It allows mammals to obtain the nutrients they need from food to stay alive and healthy.

Blood is distributed from the surface of a bone to deeper central canals through channels known as Haversian canals.
What is Haversian canal?
Haversian canals are small channels that run through the bone tissue, and they serve as the highways for blood vessels, nerves, and lymphatic vessels. They distribute blood and other essential nutrients to the bone tissue and allow for the removal of waste products.
These canals are surrounded by concentric layers of bone matrix, known as lamellae, and they help to maintain the structural integrity of the bone. The distribution of blood through the Haversian canals is essential for the health and maintenance of the bone tissue.

What are the three kinds of muscle tissues? Where is each located?
Answer:
Cardiac, smooth, and skeletal muscle tissues.
Explanation:
Muscle tissue is classified into three types: cardiac, smooth, and skeletal. Cardiac muscle cells are found in the heart's walls, are striped (striated), and are under involuntary control. Except for the heart, smooth muscle fibers are found in the walls of hollow visceral organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are similarly under involuntary control. Skeletal muscle fibers are found in muscles that are connected to the bones. They have a striated look and are controlled voluntarily.
