How do the finger-like projections facilitate the absorption?

Biology

Nesterboy [21]3 years ago

Finger- like projections facilitate absorption in the following ways;
a) They increase the surface area of the organ eg. small intestines to allow more area of nutrients to be absorbed. The larger the surface area the more nutrients are absorbed.

b) They contain many capillaries which helps to increase the rate of nutrients absorption in the small intestines.

Schizocoelic development

The coelom is a fluid-filled body cavity, where the internal organs are suspended in. It is the cavity between the wall of the body and the digestive tract.

In the schizocoelic development of the embryo, the coelom, called the schizocoel, develops as a split in the mesoderm. The outer layer of the mesoderm attaches with the ectoderm to form a body's musculature, while the inner layer attaches with the endoderm to form the wall of the digestive tract. 

This type of development is commonly found in annelids, arthropods, and mollusks.

Feliz [49]

Answer:

1. Ends of the respiratory branches are called alveoli.

2. C. To control blood flow to different areas of the body depending on activities

Explanation:

1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.

The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.  

2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.

This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.

The same agricultural practices are used in every country of the world.
makkiz [27]

Answer:

Well you already know the answer is false but I want to elaborate on this for other people who have the same / similar question.

The main source of meat, milk and eggs in most, if not all, countries are Factory-Farms, which are highly abusive, cruel industries that provide meat to around 99% of business I assume haha. A lot of businesses that claim to use "humane" practices of getting meat, dairy and eggs are not true, there is really no human way to get meat or dairy (you can humanely get eggs though factory farms don't) you can read more about this stuff on SentientMedia (graphic content warning)

Farms around the world though use different ways of harvesting (by hand, by machine etc.) planting, different kinds of crops, different ways of waters, what kind of land they plant their crops in.

Hope this helps

have a nice day((:
