Food moves in the alimentary canal from one region to another by a process called

1. locomotion
2. pumping
3. peristalsis
4. diastole

The undigested, semisolid food is called

1. anus
2. faeces
3. rectum
4. villi

Food is absorbed through

1. villi
2. blood
3. blood platelets
4. amylase

Digestion starts and ends from

1. mouth to small intestine
2. mouth to large intestine
3. mouth to anus
4. mouth to rectum

Various steps of human nutrition are in the order

1. ingestion, egestion, digestion, absorption and assimilation
2. ingestion, egestion, assimilation, absorption and assimilation
3. ingestion, assimilation, digestion, absorption and egestion
4. ingestion, digestion, absorption, assimilation and egestion

Bile is secreted by

1. stomach
2. small intestine
3. pancreas
4. liver

The length of small intestine is about

1. 60 cm
2. 6-7 m
3. 1.2 cm
4. 86 cm

The function of hydrochloric acid in the stomach is

1. To digest carbohydrates
2. To clean the stomach
3. To kill the germs
4. To break down proteins

Gland in the walls of the stomach secretes an enzyme

2. Trypsin
3. Pepsin
4. Serotonin

Stomach secretes

1. Dilute hydrochloric acid
2. Dilute sulphuric acid
3. Dilute citric acid
4. Dilute nitric acid

The glands situated around the mouth that secrete amylase enzyme are called

1. Salivary glands
2. Pituitary glands
3. Hypothalamus glands
4. Extra cellular glands

The salivary glands secrete

1. Amylase
2. Pepsin
3. Trypsin

The digestion of food in amoeba is

1. Intracellular
2. Intercellular
3. Intravenous
4. None of these

Assimilation is

1. The process of breaking large food molecules into simpler molecules
2. The process by which undigested food is ejected out of the body
3. The process by which the digested food carried by the blood is taken in by the cells of the body
4. Process of inter-exchange of oxygen and carbon dioxide between haemoglobin and the cells of the body

Amoeba procures food through

1. Proboscis
2. Pseudopodia
3. Cilia
4. Tongue

Respiration is
