Which type of tissue prevents toxins from entering the blood from the GI tract?
The epithelial tissue lining the gastrointestinal (GI) tract acts as a barrier to prevent toxins from entering the bloodstream. The tight junctions between epithelial cells help regulate the passage of molecules, allowing nutrients to be absorbed while blocking harmful substances.
Which layer of the alimentary canal contains loose connective tissue glands and lymphatic vessels and nerves?
The submucosa layer of the alimentary canal contains loose connective tissue, glands, lymphatic vessels, and nerves. This layer supports the mucosa and helps to transport absorbed nutrients from the digestive tract.
What absorbs nutrients and removes waste?
The digestive system absorbs nutrients from food through the walls of the intestines, while the excretory system removes waste products from the body, primarily through the kidneys and urinary system.
Which process propels the food through the digestive tract?
Peristalsis is the process that propels food through the digestive tract. It involves rhythmic contractions of the muscles in the gastrointestinal tract that push food and nutrients along the digestive system.
What nutrients are absorbed from the digestive tract directly into the blood?
Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed from the digestive tract directly into the blood.
What are the two major routes of nutrient transportation in the body?
Some nutrients are consumed by diffusion and others are actively transported from the digestive tract.
True or false. fat is adsorbed directly from the digestive tract to the blood.?
False, fats go to the lymphatic system.
What is lymphatic tissues?
The nasopharyngeal lymphatic tissue is the mucosal lymphoid tissue of the respiratory tract.
What organ system removes substance from the blood combats disease maintains tissues fluid balance and absorbs fat from the digestive tract?
The lymphatic system.
Nutrients from the digestive tract enter from what veins?
Hepatic portal system (vein)
What organ system transports fats from the gastrointestinal tract to the cardiovascular system?
The lymphatic system defends the body against disease by producing lymphocytes. It also absorbs lipids (fats) from the intestines and delivers them to the blood.

What system is the gastrointestinal tract?
The gastrointestinal tract is part of the digestive system, which is responsible for processing food and extracting nutrients to support the body's functions. It consists of various organs including the mouth, esophagus, stomach, small intestine, and large intestine.
What are the small lymphatic vessels that extend into the villi called?
The small lymphatic vessels that extend into the villi of the intestines are called lacteals. These specialized vessels play a crucial role in the absorption of dietary fats and fat-soluble vitamins, transporting them into the lymphatic system. Lacteals help facilitate the movement of chyle, a milky fluid containing fat droplets, from the digestive tract into the bloodstream.
Which process propels the food through the digestive tract?
Peristalsis is the process that propels food through the digestive tract. It involves rhythmic contractions of the muscles in the gastrointestinal tract that push food and nutrients along the digestive system.
