Why is the ventricle of the frogs heart thicker than the atria

Biology
1 answer:
Lemur [1.5K]2 years ago

Answer:

The ventricles of the frog are thicker than the atria because the ventricles have to pump blood to more important areas of the frog's body. The atrium shows less resistance to the flow of blood hence they do not need as thicker walls as the ventricles. The heart of a frog has one ventricle and two atria. Hence, this single ventricle should be powerful enough to pump blood to the important parts of the body.

Vesnalui [34]

Answer:

The correct answer is option C) phagocytosis in the inflammatory response.

Explanation:

Our body has an immune response mechanism for when we get hurt or when<u> it feels that something outside our body wants to harm us</u>, so its automatic reaction is to defend against all those bacteria and viruses that want to attack us.

The system is responsible for <u>identifying the antigens and destroying them.</u> The antigens are all bacteria, harmful viruses and dead substances that are found on the cells. Our system has its own proteins that are HLA antigens. But as these are normal for the body, it does not counterattack them.

There are <u>several defense mechanisms that work as barriers</u> to prohibit the passage of any bacteria that harm us, and one of these mechanisms is inflammation.

In this case, when our body suffers some kind of injury from a bacterium, a cut or a blow, the damaged cells release substances that spill onto the tissue through the blood vessels, causing inflammation.

This allows the foreign substance to be “locked up” and cannot enter the body.

These spilled substances also attract white blood cells, which are called phagocytes which<u> are responsible for eating dead germs and cells</u> through the phagocytosis process.

valkas [14]
<span>In getting her plants to grow, the gardener should use the color blue for her colored translucent sheets. The reason for this is because it will be absorbed by the plants, causing them to get the light absorption that they so desperately need. Other colors, such as green, are absorbed into plants (as can be observed by their green colors), and thus they do not absorb the light through this color.</span>

Carbon chains are principal features of both carbohydrates and lipids.what is the primary difference between these two types of
solong [7]
While both carbohydrates and lipids are made up of carbon, hydrogen and oxygen there are several differences:

1. Carbohydrates are chains of 2 or more carbon atoms.  These can be very lengthy (like long cellulose chains of glucose units). They have many polar OH groups (e.g. glucose - C6H6O6). Most carbohydrates are hydrophilic and are soluble in water because of their polar OH groups. They are not necessarily sugars nor are they necessarily sweet. They are also important components of DNA, RNA and ATP.

2. Lipids are more diverse in their chemistry. They generally have a polar region at one end (this end attracts water) and a large non polar hydrocarbon region that repels water. Lipids don't dissolve in water and instead clump together with their hydrocarbon regions on the interior. Lipids include oils, fatty acids, waxes, steroids and hormones.

EleoNora [17]
Ileostomy is a procedure where the end of the small intestine, called the ileum, is brought out of an opening in the belly through surgery. The opening is called a stoma, and its shiny, bright red in color. It is often done after the large intestine has been removed due to cancer or serious physical injuries. Having a stoma, and the need of emptying it several times a day, is disfiguring so the patient often suffer from poor self image. The patient in the case, may be concerned of being unable to continue romantic relationships due to having a stoma. As a nurse, make sure to first make patient understand that ileostomy surgery does not involve the reproductive organs or the gonads. Then, acknowledge that while having a stoma is disfiguring, many organizations are helping increase awareness and acceptance of those who have the condition. Refer the patient to such local stoma advocacy organizations.
