Respiratory General Questions 1. What is the function of the epiglottis? a. The main function of the epiglottis is to prevent food and other particles from gaining entry into the trachea and other airways. 2. Do you see any anatomical reason why the right lung has more lobes than the left lung - and is subsequently larger and heavier? a. The right lung may be larger and heavier because it has more room to develop as such. The heart is roughly centered in the chest cavity; however‚ it is slightly

This requires body to communicate with the organs‚ this is established through two very highly specialized systems; nervous system and endocrine system‚ they use electrical impulses and hormones to communicate respectively1. It is vital for our body to maintain homeostasis for our survival‚ this ability of the body allows us to adapt to our environment which is why we can live

The second is nutrient medium‚ which is the standard growth medium for most microbes. It contains heat stable digestive products of proteins called peptones and beef broth to promote bacterial growth.

process of converting the food you eat into nutrients that your body can use for energy‚ growth and cell repair needed for survival. The digestion process not only takes in nutrients but also eliminates the waste products from your food. The digestive system is a series of long twisted tubes that start at your mouth and goes all the way down to your anus. It’s made up of different tissues that have important functions in breaking down the food. Here is where the whole process starts‚ the mouth

Respiratory system: Minute ventilation is the quantity of oxygen which is taken in by your lungs per minute. When we exercise there is a higher oxygen intake per minute due to a higher breathing rate‚ we will also need more oxygenated blood cells to go round to the muscles in use to help try and prevent muscular injuries. The reason why when minute ventilation increases is positive to an athlete is because there is a higher intake of oxygen and nutrients needed. This will mean that the athlete

dairy‚ there are no good answers that apply across the board. Estimates show that 3/4 of people are intolerant to dairy. If you have any digestive discomfort‚ or if you’ve been diagnosed with any other food sensitivities‚ like celiac disease‚ it might be a good idea to cut out all dairy in order to heal your digestive system. Having a functioning digestive system is one of the most crucial aspects of health‚ as your digestion takes the nutrients from your food and turns it into fuel that is usable

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without
