Match the words in the left column to the appropriate blanks in the sentences on the right. make certain each sentence is complete before submitting your answer. gastrin cholecystokinin gastric inhibitory peptide secretin 1. : increases output of enzymatic-rich pancreatic juice. 2. : increases output of pancreatic juice rich in bicarbonate ions. 3. : increases hcl secretion and stimulates contraction of intestinal muscle. 4. : stimulates insulin release and mildly inhibits hcl production.

1.  Increases output of enzymatic-rich pancreatic juice- cholecystokinin

2. Increases output of pancreatic juice rich in bicarbonate ions-  secretin

3. : Increases HCl secretion and stimulates contraction of intestinal muscle- gastrin

4. : Stimulates insulin release and mildly inhibits HCl production-Gastric inhibitory peptide

Explanation:

1. Cholecystokinin is secreted by the duodenum of the small intestine and serves to stimulate the release of enzymes of the pancreas. In response to the presence of fatty acids and partially digested proteins in the duodenum, cholecystokinin triggers the release of pancreatic juice having enzymes and also stimulates the emptying of bile in duodenum.  

2. The secretin hormone is also secreted by duodenum in response to the presence of acidic chyme in duodenum. The hormone triggers the release of sodium bicarbonate from the pancreas in pancreatic juice.  

3. Hormone gastrin is released from the mucosa of the stomach in response to distension of the stomach by food and triggers gastric glands to secrete the enzyme pepsinogen and HCl. It also triggers contraction of lower esophageal sphincter and relaxes pyloric sphincter. 

4. Gastric inhibitory peptide hormone is released from duodenum in response to the presence of glucose-rich partially digested food in the duodenum. The hormone stimulates the secretion of insulin from the pancreas.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
