How is digestive system different from
Answers
Explanation:
The main difference between ingestion and digestion is that ingestion is the taking of food into the body whereas digestion is the breakdown of food into small molecules that can be absorbed by the body. ... Chemical digestion facilitates the absorption of nutrients from the alimentary canal.The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts:
The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus. It includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. Food passing through the internal cavity, or lumen, of the digestive tract does not technically enter the body until it is absorbed through the walls of the digestive tract and passes into blood or lymphatic vessels.
Accessory organs include the teeth and tongue, salivary glands, liver, gallbladder, and pancreas.having lobopodia
A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that are developed in the direction of movement. Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments.[1][2] Pseudopods are used for motility and ingestion. They are often found in amoebas.
Different types of pseudopodia can be classified by their distinct appearances.[3] Lamellipodia are broad and thin. Filopodia are slender, thread-like, and are supported largely by microfilaments. Lobopodia are bulbous and amoebic. Reticulopodia are complex structures bearing individual pseudopodia which form irregular nets. Axopodia are the phagocytosis type with long, thin pseudopods supported by complex microtubule arrays enveloped with cytoplasm; they respond rapidly to physical contact.[4]
Explanation:
define the following terms :
1.Ingestion - the process of taking food, drink, or another substance into the body by swallowing or absorbing it.
2.Absorption - the process by which one thing absorbs or is absorbed by another.
3.Alimentary canal - the whole passage along which food passes through the body from mouth to anus during digestion.
4.Digestive system - The system of organs responsible for getting food into and out of the body and for making use of food to keep the body healthy.
5.Pseudopodia - a temporary protrusion of the surface of an amoeboid cell for movement and feeding.
6.Villus - any of the fingerlike or threadlike projections from the surface of certain membranous structures, typically serving to increase surface area and facilitate the passage of fluid or nutrients.
name the following
1.differentt organs of digestive system
A. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The small intestine has three parts.
2.three ruminants animal
A.Sheep , goat and camal
answer the following question :
1.how is digestive system different from ?
A.The digestive system works very closely with the circulatory system to get the absorbed nutrients distributed through your body. ... While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine.
