The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.

Answers

Answer:

Explanation:

The  primary purpose of the  systemic  circuit is for blood to release carbon dioxide and pick up oxygen

The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.

What is pulmonary system?

It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.

Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.

The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.

The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.

This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.

Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

These 5 pictures can be related to finding the main message of the diagram. This diagram can be interpreted as the evolution of species on planet Earth because a dinosaur is shown first, a species that lived millions of years ago.

An image of the Earth is then displayed showing the familiar shape of the continents to demonstrate evolution on the Earth's surface.

Then show the grass because this represents the evolution of plant species that were expanding throughout most of the Earth.

Subsequently, a cow is shown as an example of the mammalian animals that exist today and finally the human who is the product of various evolutionary processes that resulted in the society and the world that we know today.

Answer: pulmonary vein; left atrium; left ventricle; aorta

Explanation: I just did this question in the final exam of A&P and it was correct, hope this helps:)

The basic pattern of blood flow from the lungs to the rest of the body is: pulmonary vein; left atrium; left ventricle; aorta. The option (B) is correct.

What are pulmonary vessels?

Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart. Your pulmonary veins are part of your body's pulmonary circuit. This is a system of blood vessels that moves blood between your heart and your lungs. This circuit also includes your pulmonary arteries.

For the exchange of gases to occur effectively, the lungs require a dual vascular supply known as pulmonary and systemic circulations. The pulmonary circulation is responsible for bringing deoxygenated blood from the body to the lungs for gaseous exchange and then returning oxygenated blood to the heart.

There are 4 total pulmonary veins—with 2 pulmonary veins coming from each lung, left and right—that empty into the left atrium of the heart.

An atmosphere is defined as the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is comprises of about 78% nitrogen, 21% oxygen, and 1% other gases.

Dissolved oxygen and carbon dioxide are important for marine life. Marine plants use dissolved carbon dioxide, sunlight and water to make carbohydrates through the process of photosynthesis.

Cold water holds more gas than warm water and seawater with low salinity holds more gas than high salinity water. Deep water, that has a high pressure, holds more gas than shallow water.

Why do parrots mimic people?

Answers

Answer:

Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.

Explanation:

Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.

helper t cells secrete ________ to stimulate the proliferation of b cells.

Answer:

Helper T cells are activated when they bind to their target antigen being displayed on an antigen-presenting cell. These cells then release what chemical? Cytokines, which is a chemical that signals B cells and other T cells to activate.

Helper T cells secrete cytokines to stimulate the proliferation of B cells.

What are Helper T- Cells?

Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the adaptive immune response. They are called "helper" cells because they help activate and coordinate other cells in the immune system, including B cells and cytotoxic T cells, to mount an effective response against a specific pathogen or foreign substance.

Helper T cells recognize and bind to antigens presented by antigen-presenting cells, such as dendritic cells, and then secrete cytokines that activate and differentiate other immune cells.

They also play a role in regulating the immune response to prevent excessive inflammation and tissue damage. Helper T cell dysfunction or depletion is associated with a number of autoimmune and infectious diseases.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman both produce melanin, but both have one parent with albinism. What is the probability that their first child will have albinism

Answers

Answer:

The child has a 1/4 chance of having albinism

Explanation:

I hope this helps!

For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still, carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.

What is the probability that their first child will have albinism?

This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.

Do both parents have to carry the albinism gene?

Yes, albinism is passed down (inherited) through families. People are born with albinism when they inherit an albinism gene from their parents. In albinism, both parents must carry an albinism gene for their child to be born with albinism.

Answers

Answer:

Explanation:

As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.

What is osmotic potential?

Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.

The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

in humans, how does the circulatory system bring oxygen to every cell in the body?

Answers

Answer:

I found this in a science text, hope it helps.

Explanation:

"Blood from the heart is pumped throughout the body using blood vessels. Arteries carry blood away from the heart and into capillaries, providing oxygen (and other nutrients) to tissue and cells. Once oxygen is removed, the blood travels back to the lungs, where it is reoxygenated and returned by veins to the heart."

Basically, blood from the heart is taken away by arteries and then into capillaries, transferring oxygen to cells.

I hope I could help!

The circulatory system of human body brings about oxygen to the every cell by the help of blood. The heart of human body helps to pump up the blood with oxygen and makes it oxygenated.

What is the size of a human heart ?

A size of a human heart is a size of a human fist it has 4 chambers where with 2 auricles and 2 ventricles. The auricles receive the oxygenated blood and the ventricles get the deoxygenated blood.  

The human heart is bringing oxygen to the cells of the body where the oxygen combined with the Fe component that is iron of the blood and reaches every cell of the blood through the blood. Blood is transported to every cell of the body through the blood vessels.

Arteries carry the oxygenated blood and ventricles carry the deoxygenated blood where the blood that reaches the cellular level by the veins and the arteries along with the blood vessels that form a network.
